Technical Systems, a division of RAE Corp., added adiabatic evaporative cooling equipment to its product line. Dubbed Adiabatic Pre-cooling Evaporative X-change (APEX), the cooling technology combines evaporative cooling technology with air cooling to deliver low maintenance, highly efficient cooling systems.

Technical Systems will target data centers and light-industrial-scale applications such as hospitals, colleges and universities. The adiabatic technology optimizes energy efficiency by only utilizing evaporative cooling technology when ambient air temperatures are high enough to render air cooling inefficient. During all other times, precooling with evaporative technology is not needed and the water supply can be shut off. Adiabatic cooling systems can reduce operating costs by optimizing water usage in climates that support them.
