Raypak offers its complete line of residential gas heaters in an ASME version. You can select the Millivolt, Digital Electronic or Digital Low NOx to be factory equipped with ASME waterways. Raypak has state inspectors on-site daily performing certifications for our pool and commercial boiler production that may require ASME. Being in the boiler business for over 50 years truly makes Raypak the leader for your commercial needs.

Why ASME?
Some local codes require that public pools, pools that are in a condominium and apartment or other commercial application be ASME certified. ASME stands for American Society of Mechanical Engineers. They are a non-profit group which sets many industrial and manufacturing standards. A pool heater that is made to ASME standards will perform to a set of specifications as determined by ASME, specifically in relation to the operating water pressure the appliance can handle. Each and every ASME heat exchanger that goes into a Raypak heater is certified by a state inspector to make sure it complies with the ASME code for that particular product

ASME Code Heat Exchanger
++ Cast Iron Glass-lined Header
Raypak applies its years of commercial boiler experience to the design of its cast iron glass-lined headers. A metal header design allows for the higher working pressures required by ASME. All ASME headers are inspected upon arrival at Raypak and each lot (pour date) tested by an independent laboratory. Only after the material passes stress analysis and metal composition tests is it approved for use in an ASME unit.

++ All Copper Fin Tube Heat Exchanger
All Raypak RP2100 ASME gas heaters come standard with .065-IN wall integral copper finned tubes. This tubing is over 50% thicker in wall thickness than standard tubing. Since the fins are integral to the tube, maximum heat transfer is attained. The fin tubing is made from one piece of extruded copper tube, not from separate fins attached to the copper tubes. Every RP2100 has the same robust design tube bundle that is used in Raypaks large gas commercial boilers. Built to last, built Raypak tough.

++ CPVC 2-IN Water Connections
Standard with every RP2100 is a set of 2-IN slip fit CPVC water connections to make your installation secure and effortless. These couplings screw into the 2-IN flanged header. You can also direct plumb your copper pipe into the flanged header.
