Cold Water Solutions

Cold Water Start – For applications

that require reliable protection against

harmful condensation caused by frequent,

extended, cold water start-ups. Raypak’s

Cold Water Start protection system utilizes

a proportional valve to bypass water from

the boiler outlet to the inlet during start-

up, when the system return water temperature is below the

minimum acceptable level.

Cold Water Run – For applications

requiring constant condensation protec-

tion. Raypak’s Cold Water Run system uti-

lizes a variable-speed pump to inject just

the right amount of water from the main

system loop into the boiler to maintain

the optimum inlet temperature. This

approach allows the full capacity of the

boiler to be utilized to meet the system load, while at the same

time continuously maintaining the optimum inlet water tem-

perature to prevent condensation.

Multi Boiler Solutions

tures on all applications including outdoor

temperature when outdoor reset mode is

selected. Can also be used to control a mix of

condensing and non condensing boilers using

our Hybrid control algorithm. Now available

Smallest Installed Footprint

The MVB’s compact design allows for easy installation in the most challenging equip-

ment rooms. It’s easy to handle and install, but still user friendly to service. The MVB

503A thru 2003A has the smallest installed footprint of any vertical boiler, only 5.4 square

feet. MVB models 2503 thru 4003 are just 11.7 square feet.

The MVB contains all of its

components to the inside of the cabinet, so there won’t be any fans or valves hanging

off the cabinet that need extra clearance. The compact design fits through a 32” door

opening making it the perfect choice for those hard to reach retrofit projects.
