Natural gas is stored in tanks on board the vehicle at a “tank pressure” ranging from 250 psi to 3600 psi. A regulator is used to regulate this pressure to a value typically around 115 psi. As a result of the pressure drop through the regulator, the natural gas reaches temperatures nearing –200° F.
The high quality, 100% stainless steel heat exchangers from Arctic Fox, LLC designed for CNG applications. The Arctic Fox heat exchanger is utilized to prevent the natural gas from dropping below an acceptable temperature based on engine temperature and load. At low fuel rates, a thermostat is required to prevent heating of the gas above an acceptable temperature.
Features and advantages:
15 tube heat exchange increases efficiency
100% stainless steel construction
350 psi maximum operating pressure
100% independent lab certified for pressure rating
Minimum burst pressure on destructive tests of 6,000 psi.
Compact Design – mounts in tight locations
Integrated Thermostat Option Available (SFT models) steps to the front in the alternative fuels market
with an easy way to convert Compressed Natural Gas (CNG) and other alternative fuels to combustible
energy sources. It is no longer necessary to apply an “off the shelf” heat exchanger to alternative fuel
applications; now you can choose heat exchangers designed for applications in alternative fuels.
