Dual refrigeration circuit, 230 kW to 420 kW
KSA Series industrial outdoor air-cooled chillers feature a compact, all-in-one package designed to minimize installation cost, maximize usable space and lower electric bills. Designed for harsh outdoor environments KSA Series chillers require no options to operate within the standard -20°C to 52°C ambient environment conditions. Standard fluid set point temperatures of -7°C to 27°C make the KSA ideal for industrial applications. The modular design allows up to 6 refrigeration circuits to be combined into a single system for up to 2,130 kW of cooling capacity.
Chillers are available with or without integrated pumping packages, including high and low pressure pumping with dedicated stand-by and built-in pressurized and non-pressured tanks.
KSA Series chillers come standard with Dynamic Lift technology, which continuously calculates the lowest allowable refrigerant pressure for any combination of operating conditions to maximize chiller energy savings. Under steady-state process load conditions, KSA chillers provide stable process fluid temperatures within ±1.1°C.
