Raypak’s Hi Delta
Decades of expertise and technological innovations went into
creating the Hi Delta boiler, a product that incorporates features
sought after by engineers, installers and end-users alike.
In 1948, Raypak introduced the first straight copper finned tube
boiler designed with reliability and serviceability in mind. The
tradition continues with Raypak’s Hi Delta model. It’s patented burn-
er “security blanket,” an ingenious enhancement that provides a
perfected air-gas pathway for complete combustion, makes the
Hi Delta the most adaptable sealed-combustion boiler on the market
today.
While many manufacturers claim simple, convenient heat exchanger
removal, servicing the Hi Delta couldn’t be more straightforward.
Just open the unit from the front and slide it out on built-in runners.
Adding to the Hi Delta’s ease of use is the On-board Diagnostic
Center. In the event of an operating problem, this key enhancement
allows an on-site technician to quickly review the unit’s entire fault
history, in easy to understand “real English”. No cryptic codes to
deal with. Our diagnostic center even offers possible solutions to the
problem at hand.
The Hi Delta product family covers the full spectrum of both indoor
and outdoor applications including space heating, process heating,
pool heating and domestic hot water heating.When installed
indoors, the Hi Delta’s versatility is revealed in smaller vent
diameters, direct-venting and the convenience of stacking without
an increased footprint.
Raypak’s focus on customer satisfaction goes beyond product
design. Like all Raypak boilers, every Hi Delta is factory-fire tested,
assuring reliable start-up upon installation.
For over 60 years, Raypak professionals have earned their reputation
as The Hot Water Management Experts. From system design through
installation and start-up, you can count on your local Raypak
Representative and the backing of the industry’s best sales staff,
applications engineers and service department.
