Ambient Cooling Systems

Ambient liquid cooling systems are very energy efficient systems for removing heat. Unlike compressor or thermoelectric based cooling systems there is only a pump and fans that need to be powered. These systems are the ideal solution whenever ambient temperatures are low or the heat source accepts temperatures above ambient such as CPUs or power electronics.

Our turbo compressor recirculating chillers operate in the ambient cooling, i.e. free cooling mode most of the time all year long, only during hot summer days the compressor is powered on. In the free cooling mode EER (energy efficiency ratio in W/W) values of up to 50 can be reached. Our turbo compressor recirculating chillers are available in 35 kW and 45 kW models and a 120 kW model is to be launched in 2021.

Our compact liquid cooling systems against ambient air are the ideal solution where heat loads of 1 to 4 kW need to be removed and coolant temperatures of 10 to 30 K above ambient temperature are acceptable. The system consist of high performance Fans, a reservoir and a fan and a pump, both operated from mains AC voltage.

The copper tube heat exchanger versions are suitable for water as coolant, the all aluminum heat exchanger versions for oil and brines. The specific performances range from 50 to 125 W/K, i.e. cooling capacity per degree initial temperature difference, which is defined as difference between hot coolant temperature and cold ambient air temperature. A variety of positive displacement and centrifugal pumps are available.
