WATER - (For Condensers)

Water-cooled condensers are designed to operate 
with a water/propylene glycol solution, supplied at 
a temperature of 41°F to 118°F (7.2°C to 10°C). A 
minimum of 10 percent propylene glycol by weight 
is recommended. If water piping is run outdoors, 
35 percent propylene glycol by weight will give burst 
protection, (not freeze protection), to approximately 
–40°F (–40°C). Regardless of the amount of 
propylene glycol, it must be ensured that the water 
loop has adequate corrosion inhibitors.

The water flow requirements for each case are:

 

5-Door: 4 Gallons per Minute (GPM)

Auto balance valves are provided. 

The inlet and outlet water connections are attached 
using a 3/4 inch adapter. Use clamps (not supplied) to 
tighten the hoses in place.

There are hand valves for system isolation located 
on the inlet and outlet water connections. The hand 
valves, hose adapter and their locations on the case are 
shown on the illustrations on the next page. Trapped 
air must be removed at high points of the water piping.
