The design, materials, fabrication, examination, and testing of every Colmac Coil ammonia evaporator coil complies fully with the requirements of the ASME Code for Pressure Piping B31.5 “Refrigeration Piping and Heat Transfer Components”. Colmac Coil utilizes the quality systems defined by ASME Sections XIII and IX of the Pressure Vessel Code for the design and manufacture of its ammonia heat exchangers. IIAR-2 requires that ammonia piping systems be built and installed according to the requirements of ASME B31.5. Full compliance with ASME B31.5 for evaporator construction insures that your ammonia refrigeration system is constructed with the same consistent quality standards throughout. Don’t settle for anything less than full B31.5 compliant ammonia evaporators!
