* Based on 50° F (10° C) water temperature (100% water) leaving the chiller, standard pump selections, 95° F (35° C) ambient air

conditions.

Consult factory for other conditions.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Standard pump selection. Larger pumps available as options.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Based on 50° F water temperature leaving the chiller 60° F (15° C) water temperature returning to the chiller. § Pressure at pump discharge.

** Control can be extended upward approximately 11 inches, which may or may not increase the overall height of the unit.
