ClimaCool Corporation's (Oklahoma City, OK) Modular Chiller Series is available in 30 ton and 50 ton capacities and measures 29 1/2 in. in width, allowing them to pass through existing equipment room doors or into standard passenger elevators, according to the manufacturer. In addition, the module's shorter depth provides a tighter turn radius for maneuverability in hallways and around tight corners. The units are designed to be field-coupled to meet tonnage requirements of up to 400 tons.
