Accuchiller KSE Series Packaged Outdoor Chiller

Dual refrigeration circuit, 40 to 60 Ton

Dual fluid & refrigeration circuit, 80 to 120 ton

KSE 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 KSE Series chillers require no options to operate within the standard -20°F to 125°F ambient environment conditions. Standard process fluid temperatures of 20°F to 80°F are ideal for industrial applications. The modular design allows up to 12 refrigeration circuits to be combined into a single system for up to 720 tons 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.

KSE Series chillers come standard with Dynamic Lift technology to continuously calculate the lowest allowable refrigerant pressure for any combination of operating conditions for maximize chiller energy savings and stable process fluid temperatures of +/- 1°F.
