Raypak 267 - Manual (Page 4)

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 commercial boiler production that may
require ASME. Being in the boiler business for over 50
years truly makes Raypak the leader for your commer-
cial needs. Why ASME? Most local codes require that
public pools, pools that are in condominiums, apart-
ments, or other commercial applications, 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 stan-
dards must perform to a set of specifications as determined by ASME, specifically in rela-
tion 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 composi-
tion 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 appli-
cations. 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.
