NATURAL GAS ENGINES DESCRIPTION

The HPR-3600 is a single stage high pressure regulator designed for high pressure CNG (Compressed Natural Gas) systems. This regulator is engine coolant heated to prevent freezing and has dual outlet ports for universal installation flexibility. The HPR is rated up to 3,600 psi (248.2 Bar) inlet and provides a regulated outlet pressure of 150 ± 20 psi (10.3 ±1.4 Bar) which makes it compatible with the IMPCO “P” (positive) type regulators. It is also supplied with an external pressure relief valve. A mounting bracket is available separately.
