Modular Air-Cooled Chillers

Jetson Modular Air-Cooled Chillers feature an industry leading small-footprint and modular design that makes them ideal for easy replacement, retrofit, or new construction applications. With high efficiency, EC motor driven condenser fan, and low sound fan blade design, the unit produces a very low noise level and offers increased part-load unit efficiency and superior redundancy to single machines. By adding modules to the Jetson array, modular chillers can satisfy both current and future chilled water needs.
