The D50 is engineered for heavy-duty diesel vehicles with 401–500L (approximately 106–132 gallon) fuel tanks. This includes Class 8 trucks, long-haul buses, heavy construction equipment, and similar commercial vehicles. If your tank is smaller (≤100L), consider the D10/D11; for 200L tanks, use D20/D21. Vehicles with dual tanks or capacities exceeding 500L may require 2–3 units for optimal performance.

Installation requires a qualified technician. The D50 ceramic device is placed directly into the diesel fuel tank through the filler neck or access port. Critical: avoid contact with the fuel level sensor float, as this can cause inaccurate gauge readings. The device is non-invasive—no engine modifications, cutting, or drilling required. Once installed, it works passively for approximately 10 years with zero maintenance.

No. The D50 is a fuel-only solution—it does not include the air purifier component found in the D51 model. It uses the same patented ceramic molecule-enhancing technology to improve fuel atomization and combustion, but focuses solely on the fuel system. If you want both fuel and air optimization, consider the D51 package.

The D50 contains a proprietary ceramic formulation that emits far-infrared radiation. This energy breaks down diesel fuel molecule clusters, reducing viscosity and enabling finer atomization during injection. The result: more complete combustion, improved fuel efficiency (typically 5–15% in heavy-duty applications), and lower emissions (HC, CO, NOx). The technology is patented and has been validated by TÜV Rheinland, Taiwan, and multiple commercial fleet operators including KSRTC India and IFFCO UAE.

Absolutely. The D50 is a passive, non-invasive device—it does not chemically alter the fuel or interact with engine components. It simply enhances the physical properties of diesel molecules through far-infrared energy. The ceramic material is inert, non-toxic, and designed for long-term contact with diesel fuel. It will not void manufacturer warranties or cause corrosion, clogging, or sensor interference when installed correctly (avoiding the fuel level float).

The D50 is a B2B product designed for fleet operators, authorized distributors, logistics companies, government transport departments, and commercial vehicle operators managing multiple heavy-duty diesel units. While individual owner-operators can purchase for their own trucks, we do not offer retail-style trials or single-unit promotions. Pricing and commercial terms are tailored for volume buyers—contact us with your fleet size, tank specs, and timeline for a proper quote.

Real-world results from commercial deployments show fuel efficiency improvements of 5–15% and emissions reductions up to 85% (depending on baseline vehicle condition). Examples: KSRTC India heavy-duty bus fleet achieved 8–10% fuel savings and converted BSII buses to BSIV emission standards; IFFCO UAE diesel trucks averaged 7.4% monthly fuel savings; Saudi logistics operators reported 18% improvement. Your results will vary based on vehicle age, maintenance history, fuel quality, driving habits, and load conditions. This is not a magic bullet—it's a proven enhancement tool.

No. Greentech does not provide free samples, risk-free trials, or client-funded proof-of-concept programs. The way to validate the D50 is through your first commercial order—just as our established customers (KSRTC, IFFCO, Volvo/Mercedes fleets in Portugal) did. We provide technical documentation, third-party certifications, and case study references upfront. If you're a serious fleet operator or distributor, we're happy to discuss commercial terms and deployment timelines—but validation happens through purchase, not free testing.

The D50 has an operational lifespan of approximately 10 years under normal commercial use. It requires zero maintenance—no cleaning, recharging, or replacement of components. Once installed, it works continuously and passively. After 10 years, you can replace it with a new unit to continue benefiting from enhanced fuel performance.

Distributor-level pricing and territorial rights are evaluated case-by-case and only apply to regions where we do not currently have authorized distributors. If you're interested in becoming a distributor, please provide: (1) your company name and business type, (2) target country/region list (be specific—include all territories), (3) estimated first-order volume, and (4) deployment timeline. Our team will verify current distributor coverage in those areas and respond accordingly. We do not disclose pricing or grant exclusivity in regions where we already have active partners.

The D50 package (SKU: GT-D50, US$499) includes one Greentech D50 Heavy-Duty Diesel Fuel Enhancer unit (ceramic device only, no air component). To place an order or request a fleet quote, contact us with your company details, fleet size, fuel tank specifications, and expected order quantity. Our business development team (Rita) will provide a formal quotation, lead time, and shipping terms. We do not publish checkout pricing online—all transactions are B2B and require direct engagement.

Installation is straightforward but should be handled by a qualified technician or fleet mechanic. The D50 device is placed directly into the diesel tank through the filler neck — no engine modification required. Critical: position the device away from the fuel level sensor float to avoid interfering with your fuel gauge reading. While experienced DIYers can manage it, we recommend professional installation to ensure correct placement and avoid sensor issues.

Both cover the same tank capacity (401–500L) and use identical patented ceramic fuel-enhancing technology. The D51 includes an additional air purifier device for the intake system; the D50 is fuel-side only (no air device). Choose D50 if you want fuel efficiency and emission improvements without modifying the air intake, or if your fleet already has aftermarket intake systems. Performance and lifespan are comparable.

Real-world fleet data shows fuel efficiency improvements typically range from 5–25%, with emission reductions (HC, CO, NOx) up to 85% depending on baseline vehicle condition. For example, KSRTC India's heavy diesel bus fleet averaged 8–10% fuel savings and met BSIV standards from older BSII vehicles; IFFCO UAE trucks saw 5–13% monthly savings (7.4% average); Saudi logistics fleets recorded up to 18% improvements. Actual results depend on engine age, fuel quality, maintenance history, and driving patterns — older, poorly maintained vehicles often see larger gains.

Absolutely safe. The D50 is a completely non-invasive device — it sits passively in the fuel tank and requires no drilling, wiring, or engine modification. It's been certified by TÜV Rheinland, Taiwan, and Australia's DOTARS/Orbital under ADR-79/81 standards. Because there's no alteration to factory components, it does not void OEM warranties. The ceramic material is chemically inert and poses no contamination risk to fuel systems.

Greentech operates on a B2B commercial model — we do not offer free trials, risk-free pilots, or client-funded proof-of-concept programs. Product validation happens through your first commercial order. If you're a fleet operator or authorized distributor interested in testing, your initial purchase serves as the validation phase. We're happy to provide case studies, third-party test reports, and volume pricing to help you make an informed decision. Contact us with your fleet size, tank specs, and timeline for a formal quote.

The D50 is a B2B product aimed at fleet operators, logistics companies, transportation authorities, authorized distributors, and EPC contractors managing heavy-duty diesel operations. While individual owner-operators with qualifying vehicles (401–500L tanks) can purchase, our pricing and support structure are designed for volume buyers and commercial deployments. If you're running a single truck, you're welcome to order — just note that we don't provide personalized ROI calculators or custom trial terms for one-off buyers.

Pricing is not published online — we quote based on order volume, tank configuration, and deployment timeline. To receive a formal quote, please provide: (1) your company name and type (fleet operator, distributor, contractor), (2) country/region of operation, (3) number of vehicles and fuel tank sizes, and (4) planned implementation schedule. If you're interested in becoming an authorized distributor, we'll also need your target territory list so our team can verify current representation in those regions before discussing terms. Contact us directly to start the conversation.

The D50 (and the entire Greentech line) is validated by multiple independent bodies: TÜV Rheinland and Taiwan for safety and performance, Australia's DOTARS/Orbital for ADR-79/81 emissions compliance, and field-tested by government and commercial fleets worldwide. Notable deployments include India's KSRTC bus fleet (25–85% emission cuts, BSII-to-BSIV upgrade), UAE's IFFCO heavy truck fleet (7.4% avg. fuel savings), Portuguese Volvo/Mercedes fleets (6–8% savings), and Saudi Arabia's Steady Routes Logistics (18% improvement). All tests were commercial or government-funded deployments, not free pilots.

Real-world fleet results typically range from 5–25% fuel savings, depending on vehicle age, maintenance condition, driving habits, and fuel quality. For example, IFFCO's UAE heavy truck fleet (550L tanks) averaged 7.4% monthly savings, while Saudi logistics operators reported up to 18%. The D50 works by reducing fuel molecule clustering and viscosity, leading to finer atomization and more complete combustion — but actual savings vary. This is why we require a commercial first order as your validation, not a free trial.

Yes, the D50 is ideal for any heavy-duty diesel application with a 401–500L tank — including excavators, loaders, dump trucks, transit buses, and coach buses. India's KSRTC government bus fleet uses our technology across hundreds of vehicles, achieving 25–85% emission reductions and significant fuel efficiency gains. If your equipment uses diesel and falls within the tank size range, the D50 will work.

Yes, we offer B2B volume pricing for fleet operators, authorized distributors, and institutional buyers. However, pricing is not disclosed in this chat — we need to understand your fleet size, tank specifications, timeline, and (for distributors) target markets first. Please provide your company name, location, estimated order quantity, and implementation timeline, and our sales team (Rita) will follow up with a tailored quote. Note: distributor pricing is only available in regions where we don't currently have an authorized distributor.

We ship globally to B2B customers — fleet operators, distributors, and institutional buyers. Lead times depend on order volume and destination, typically 2–4 weeks for standard orders. For large fleet deployments or new distributor partnerships, we'll coordinate logistics and timelines during the quoting process. If you're inquiring about becoming a regional distributor, we'll need to verify whether your target markets already have authorized distributors before proceeding.

No, Greentech does not offer free trials, free pilot programs, or client-funded proof-of-concepts. We are a B2B product with validated performance across multiple government and commercial fleets worldwide — including KSRTC India, IFFCO UAE, and fleets in Portugal, Saudi Arabia, Qatar, and Vietnam. Your first commercial order serves as your product validation. We're confident in the technology, and our global track record speaks for itself. If you need performance data before committing, we're happy to share third-party test reports and case studies during the sales process.

The D50 is designed for heavy-duty diesel vehicles with fuel tanks between 401–500 liters (approximately 106–132 gallons). This includes Class 8 trucks, heavy-duty buses, large construction equipment, and similar applications. If your tank exceeds 500L, consider the D51 (which includes an air device) or multiple units for larger configurations. For tanks under 400L, check out our D20/D21 or D10/D11 models.

The D50 is installed inside the diesel fuel tank — no engine modification required. Simply drop the ceramic device into the tank, ensuring it doesn't interfere with the fuel level sensor or float gauge (incorrect placement can affect fuel gauge readings). We recommend professional installation by a qualified mechanic or fleet technician to ensure proper positioning. The device remains submerged in diesel and works continuously for approximately 10 years with zero maintenance.

Greentech's patented ceramic formula emits far-infrared radiation that breaks down fuel molecule clusters, reducing viscosity and improving atomization. This means finer fuel mist, more complete combustion, better fuel efficiency, and lower emissions (HC, CO, NOx). The technology is non-chemical, non-invasive, and requires no power source — it works purely through the physical properties of the ceramic material in contact with diesel fuel.

Yes. The D50 is completely non-invasive and chemically inert — it doesn't alter fuel composition or introduce additives. It's compatible with all diesel engine types, including modern common-rail, turbocharged, and emissions-compliant (Euro 6, EPA Tier 4) systems. The device is certified by TÜV Rheinland, Taiwan, and other international bodies. Just ensure proper installation to avoid interfering with fuel sensors.

The D50 is a B2B product designed for fleet operators, logistics companies, heavy-duty trucking businesses, construction firms, mining operations, and authorized distributors. It's ideal for organizations running multiple heavy-duty diesel vehicles (buses, Class 8 trucks, large machinery) with 401–500L tanks and looking to reduce fuel costs and emissions at scale. We do not offer individual consumer sales, free trials, or client-funded proof-of-concept programs.

Yes. We provide distributor-level pricing for qualified fleet operators, authorized distributors, and institutional buyers. To request a quote, please provide: your company name and type, country/region, fleet size and tank specifications, estimated order quantity, and implementation timeline. Our sales team (Rita) will assess your needs and respond with pricing. Note: regional distributor pricing is only available in territories where we do not currently have exclusive representation.

No. Greentech does not offer free trials, free pilot programs, or client-funded POCs. Product validation occurs through your first commercial order — this is standard B2B practice for our technology. We provide extensive third-party test data (TÜV, , KSRTC India, IFFCO UAE, etc.) and case studies to support your purchasing decision. If you need further technical documentation before ordering, contact our sales team.

The D50 is engineered for heavy-duty diesel vehicles with 401–500L fuel tanks — think Class 8 trucks, large buses, construction equipment, and agricultural machinery. If your tank is closer to 200L, check out our D20/D21. For tanks over 500L or dual-tank setups (common in long-haul tractors), you'll typically need 2–3 units of D50 or D51 to cover the full capacity.

The D50 uses the same patented ceramic core as the D51 — it releases far-infrared energy to break down diesel molecule clusters, reducing viscosity and improving atomization for more complete combustion. The difference? D50 is fuel-only (no air intake component), making it simpler to install in certain fleet configurations. You still get fuel efficiency gains and emission reductions; the air device in D51 just adds an extra boost for intake air quality.

Installation involves placing the D50 device inside your fuel tank — but it's not a pure DIY job. You'll need to ensure it doesn't interfere with the fuel level sensor float (or your gauge will read incorrectly). We recommend having a qualified mechanic or fleet technician handle the install to avoid sensor issues and ensure optimal placement. No engine modifications required — it's completely non-invasive.

The D50 is a B2B product designed for fleet operators, authorized distributors, logistics companies, and institutional buyers (e.g., municipal transport, construction firms). If you run a single heavy-duty truck and want to trial the technology, you're welcome to purchase — but we don't offer free samples or risk-free pilots. Your first order is your validation. For bulk orders or distributor pricing, contact us with your fleet size, tank specs, and timeline, and our team (Rita) will provide a commercial quote.

You get one GT-D50 fuel enhancer unit (no air device) for US$799. That's it — no subscriptions, no filters to replace, no maintenance. The ceramic core lasts approximately 10 years under normal operating conditions. Installation labor is separate (arranged by you), and if you're ordering for a fleet, volume pricing is available. Shipping costs depend on your location and order size.

We don't offer free trials, client-funded POCs, or risk-free pilots. Greentech validation happens through your first commercial order — just like the fleets in India, UAE, and Saudi Arabia did. If you're a fleet operator or distributor, we're happy to discuss your requirements and provide references from similar deployments, but the product proof comes from real-world use in your own operation. Contact us with your fleet details, and we'll help you size the right solution.

D50 is fuel-only; D51 includes both fuel and air intake devices. If your priority is simplicity and you're okay with fuel-side gains alone, D50 works great. For maximum performance (fuel + air), go D51. For dual-tank heavy-duty trucks (common in Class 8 long-haul rigs with 300+ gallon total capacity), you'll typically need 2–3 units of D50 or D51 to cover both tanks. Share your exact tank configuration with us, and we'll recommend the optimal setup.

The D50 (and the Greentech platform) is certified by TÜV Rheinland, Taiwan, and Australia's DOTARS/Orbital under ADR-79/81. Real-world fleet testing includes India's KSRTC government bus fleet (25–85% emission reduction, 8–10% fuel savings), UAE's IFFCO heavy trucks (7.4% average savings), Portugal's Volvo/Mercedes fleets (6–8% savings), and Saudi Arabia's Steady Routes Logistics (18% savings). We've also been validated by Hong Kong Polytechnic University dyno tests and Vietnam's Grab fleet trials. All are commercial deployments or government trials — not free pilots.

Both use the same patented ceramic fuel-enhancing technology and are rated for the same tank size (401–500L). The D50 is fuel-only — no air device included — making it a more cost-effective option if you don't need intake air treatment. The D51 includes both fuel and air components for maximum emissions reduction. Choose D50 if your priority is fuel efficiency and lower upfront cost; choose D51 if you need comprehensive emissions control for compliance or environmental goals.

Installation is non-invasive: the ceramic device is placed directly into the diesel tank through the filler neck or access port. Critical: position it away from the fuel level sensor float to avoid interfering with your fuel gauge. Professional installation by a fleet technician or diesel mechanic is strongly recommended to ensure correct placement and avoid sensor issues. The device requires no wiring, no engine modifications, and no ongoing maintenance.

Fleet operators typically see 5–15% fuel efficiency improvements, with some heavy-duty applications reaching up to 25% under optimal conditions. Real-world results depend on vehicle age, maintenance history, driving patterns, and fuel quality. For example, IFFCO's UAE truck fleet (550L tanks) averaged 7.4% monthly savings; Saudi logistics operators reported 18% on highway routes. The D50 works by breaking down fuel molecule clusters for finer atomization and more complete combustion — older engines with poorer fuel systems tend to show larger gains.

Greentech is a B2B product, and we do not offer free trials, risk-free pilots, or client-funded proof-of-concept programs. The way fleets validate our technology is through an initial commercial order — not free samples. We have extensive third-party test data (KSRTC India, IFFCO UAE, TÜV Germany, etc.) and can share case studies and certification reports to support your decision. If you're a fleet operator or authorized distributor interested in volume pricing, contact us with your fleet size, tank specs, and timeline, and our sales team (Rita) will provide a formal quote.

US$799 gets you one GT-D50 ceramic fuel enhancer unit, designed for one 401–500L diesel tank. Installation hardware and labor are not included — you'll need a qualified technician for proper placement. For fleet operators ordering multiple units (10+, 50+, 100+ units), we offer volume pricing. Authorized distributors in regions without existing representation may qualify for distributor-level pricing. To request a fleet quote, provide: company name, location, number of vehicles, tank sizes, and deployment timeline. Our team will follow up with a customized proposal.

Yes — while the D50 focuses on fuel enhancement (no air device), it still significantly reduces emissions by improving combustion efficiency. Fleets report visible reductions in black smoke, and lab tests show drops in HC, CO, and particulate matter. For example, India's KSRTC bus fleet achieved 25–85% emissions reductions and upgraded BSII vehicles to meet BSIV standards using our technology. If your fleet faces strict emissions regulations or you want maximum reduction, consider the D51 (fuel + air) for even stronger results. The D50 alone delivers measurable improvements at a lower cost.

The D50 is ideal for any heavy-duty diesel application with a 401–500L tank: line-haul trucks, intercity coaches, construction equipment, agricultural machinery, and stationary gensets. For marine vessels, we have a dedicated Marine Fuel Saver (MFS) line — one MFS unit per 1,000L (1 ton) of tank capacity, with professional onboard installation required. If your equipment uses LPG or CNG instead of diesel, we have a separate Gas Fuel Saver product that installs inline in the gas pipeline. Contact us with your equipment type and fuel system specs, and we'll recommend the correct Greentech solution.
