Integrated LNG & L-CNG Infrastructure Solutions
Turnkey cryogenic fueling systems powered by Endurance technology. From vacuum-insulated storage to high-flow dispensing, we deliver 99.9% reliability for heavy-duty transportation and industrial energy.
Overview
Shubh Tradex delivers complete, turnkey LNG and L-CNG refueling infrastructure in strategic partnership with Endurance Energy. We bridge the gap between world class cryogenic engineering and local project execution, offering solutions that range from high vacuum storage tanks to high flow dispensing systems for heavy duty transportation and industrial gasification.
Our L-CNG solutions specifically cater to the growing demand for "Integrated Energy Hubs," where a single LNG source is used to provide both LNG for heavy trucks and high pressure CNG for passenger vehicles. Every system we deploy is optimized for low boil off rates, rapid refueling, and 24/7 reliability in the demanding Indian environment.
Key Technical Differentiators
- Vacuum Insulated Excellence: Utilizing Endurance's high vacuum, multi layer spiral winding insulation to ensure a static evaporation rate of ≤ 0.15% per day.
- Dual Fuel Capability: Seamlessly convert LNG to high pressure CNG (L-CNG) through high pressure cryogenic pump skids and modular ambient vaporizers.
- High Flow Refueling: Advanced dispensing technology capable of delivering 180 - 200 L/min, significantly reducing filling times for heavy duty fleet operators.
- Rapid Deployment Skids: Containerized and skid mounted designs that minimize onsite civil work and allow for "Plug & Play" commissioning.
- ZBO (Zero Boil-Off) Technology: Integrated pressure management systems designed to prevent gas wastage during low traffic periods.
Target Applications
- Heavy Duty Logistic Corridors: Establishing LNG "Green Highways" with high capacity storage and high flow dispensers for long haul trucking.
- Integrated CGD Hubs: Serving as Mother Stations that provide both LNG and high pressure CNG to local distribution networks.
- Industrial Gasification (IGS): Skid mounted gasification stations providing a reliable natural gas supply to factories and industrial clusters not yet reached by pipelines.
- Private Fleet Depots: Dedicated containerized refueling units for corporate mining or construction fleets.
