Specifications

ASME
The Raypak Digital heater is also available in an optional
ASME version. Raypak has state inspectors on-site daily
performing certifications for our pool heater and commer-
cial 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? Most
local codes require that public pools, pools that are in
condominiums, apartments, or other commercial appli-
cations, be ASME certified. ASME stands for American
Society of Mechanical Engineers, a non-profit group
which sets many industrial and manufacturing standards.
A pool heater that is made to ASME standards must per-
form 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 all ASME codes
for pool heaters.
Glass-Lined Cast Iron Headers
Raypak has applied its years of commercial boiler experience to the design of the cast iron
glass-lined header. A metal header design allows for the higher working pressures required by
ASME. Only after the material meets the stress analysis and metal composition tests is it
approved for use in an ASME unit.

Copper Fin Tube - Residential
The Raypak Digital is built to last with the highest quality integral
copper fin tube available. Copper is well known for its ability to
efficiently transfer heat, and is the first choice for pool and spa
heat exchanger construction. Pure copper has stood the test of time
as the industry standard for efficiency, quality and product life.
ASME Copper Fin Tube - Commercial
The Raypak Digital ASME is designed specifically to meet
State and local code requirements for public pools and commercial
applications. This heater is equipped with a thicker walled fin tube
allowing it to meet the ASME certification requirements.
Cupro-Nickel Fin Tube - Specialty
Raypak Digital heaters can be ordered with cupro-nickel fin tube
heat exchangers for added protection against aggressive water
chemistry. Although rare, there are certain applications, like health
club spa’s, where copper is just not the best choice. Cupro-nickel
offers superior tolerance to bad and fluctuating water chemistry,
thanks to a harder surface and a thicker walled fin tube.
