It is commonly known that prolonged internal condensation will dramatically shorten the life of standard boilers and

water heaters.While Raypak boilers and water heaters can operate without harmful condensation at lower inlet water

temperatures than the competition, there are still applications that require reliable protection against harmful conden-

sation caused by frequent,extended,cold water start-ups. Raypak’s ColdWater Start protection system utilizes a pro-

portional three-way 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 START

Raypak’s Cold Water Start system:

• Continuously monitors and adjusts inlet water temperature to prevent condensation

• Regulates minimum inlet water temperature during system start-up

• Shuts down boiler if the minimum inlet water temperature is not achieved

• Eliminates job site set-up with proprietary self-tuning controller and system-matched components

• Utilizes proportional three-way valve to achieve bypass

• Allows high-temperature system operation without cycling on high-limit

• Activates alarm if shutdown occurs (option)

For the same reason stated for Cold Water Starts, it is even more important to provide protection against condensation

from cold inlet water on systems where the return water temperature to the boiler will always be below the acceptable

minimum. Raypak’s Cold Water Run system utilizes 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 opti-

mum inlet water temperature to prevent condensation.

COLD WATER RUN

Raypak’s Cold Water Run system:

• Continuously monitors and adjusts inlet water temperature to prevent condensation

• Regulates minimum inlet water temperature regardless of system temperature

• Shuts down boiler if the minimum inlet water temperature is not achieved

• Protects boiler from constant low return water temperatures with its proprietary self-tuning controller

• Utilizes variable-speed injector pump to control boiler loop temperature

• Activates alarm if shutdown occurs (option)

• Pool Heating

• Low-temperature Industrial Process

• Very Low-temperature Return Water

2. Many variables can impact the proper valve sizing for multiple boilers. This sizing is provided as a guide. When in doubt consult the factory.

3. Multi-unit system ALWAYS shipped loose- Not available mounted.

4. 4” flanges, bolts and gaskets supplied by others. Multi-units with 4” valves are to be used on hydronic heating only.The valve body is cast

iron.
