Process Cooling | Temperature Control | Size Reduction | PCA SERIES 0.5 - 1.5 HP Packaged Chillers Technical Data Sheet PCA Series Packaged Chiller by AEC are specially engineered for small, demanding industrial applications. Each self-contained unit is designed for immediate hookup and is ready to supply clean, cooling water at constant temperatures. A wide range of economical options are available to meet or exceed the demands of almost any application. Control within +/- 2°F (1.1°C) is achieved using microprocessor based PID controls with autotuning capability. NEMA 1-style electrical enclosures, non-ferrous wetted surfaces, and all refrigerant safeties. In order to conserve valuable floor space, the PCA chillers offer a space-saving footprint of 20” wide x 26” deep.
