IMPCO Technologies Unveils New CNG Pressure Relief Devices


IMPCO Technologies Inc., a division of Westport Fuel Systems Inc., has released an expanded line of GFI-branded, high-pressure compressed natural gas (CNG) thermal pressure relief devices. According to the company, the new products now available globally include the following:

– High performance in-line (Model# PRD-4E);
– High performance end of line (Model# PRD-4L); and
– High performance 1 1/8″ End Plug (Model # PRD-4P; also available with integral temperature sensor).

IMPCO Technologies says the technology was developed to supplement the existing models of thermal pressure relief devices, with the new models being certified to ANSI PRD 1-2013 and available with both eutectic and glass bulb technology. The high flow discharge design ensures that, in the unlikely event that the device is activated, the integrity of the CNG system will remain intact, the company adds.
