THE ESC-SERIES: CAMBRIDGE EVAPORATIVE COOLING

Choose from Indirect, Direct or Two-Stage Evaporative Cooling Machines to meet your cooling needs.

With indirect evaporative cooling, leaders can maintain a temperature controlled work environment for their team by utilizing Cambridge’s ESC-Series.

The ESC-Series evaporative cooling unit is a semi-custom fabricated air handler that can utilize direct (DEC), indirect (IEC) evaporative cooling, or a combination of both indirect/direct (2-Stage) evaporative cooling to meet specific usage and dimensional requirements. Heating options are also available. The evaporative cooling unit uses 100% outside air to provide tempered make-up air and building cooling. The ESC-Series unit is designed for industrial, commercial, and institutional buildings needing better indoor air quality without the equipment or operating costs associated with mechanical cooling.
