EZ CAL

Safe, Simple Calibration Solution Complies with IIAR-6 Safety Standards

The Frick EZ-CAL™ test block is designed to be installed between the compressor discharge connection and the high pressure cut-out (HPCO). The unit provides a simple calibration method in compliance with safety standards, while reducing the risk of prematurely lifting a safety relief valve with a resultant ammonia release. The test block functions as a check valve for low-pressure drop — not a stop valve. This simply-designed device will safely meet the yearly testing of the HPCO as will be required by the new IIAR-6 standard. (The standard does not allow removal and bench testing of the HPCO or testing on a shutdown compressor.)
