AET has launched a range of absorption chillers that can produce cooling using heat from a solar-thermal installation or waste heat from an industrial process or a CHP system. The SAB-HW range of chillers have a single-effect absorption cooling cycle using a solution of lithium bromide in water. They have cooling capacities from 52 to 3516 kW and can modulate down to 10% of full capacity.
Noise levels are said to be low — 75 dB(A) according to ARI Standard 575. They also have low levels of vibration, enabling them to be installed on the upper floors of a building.
