DmRC-C-900-24-KIT" Double Compressor-based Recirculating Chiller

Two recirculating chillers in one cabinet, up to 900 W cooling capacity, 24 V DC power supply

The DmRC-C-900-24-KIT is a development kit suitable for applications requiring high water cooling performance in the smallest of spaces for water coolers. Based on miniature compressors, this "mini Recirculating Chiller" development kit provides two independent water cooling systems in a 19-inch rackmount insert, which can provide a combined maximum cooling capacity of 900 W. With this double chiller concept, DmRC-C-900-24-KIT can cool two heat loads independently of each other – the target temperatures for each of the two heat loads can be set individually.

The compressors’ BLDC motors are speed controlled and offer low vibration and low noise throughout the speed range. Since the water circuit is pressurized, DmRC-C-900-24-KIT manages with very small tanks (2 x 275 ml) – without the risk of cavitation in the smoothly operating centrifugal pumps. Overpressure on the cooling system also prevents the ingress of bacteria and oxygen and thus extends the maintenance intervals. An electric air pump generates the pressure on the two water circuits and is also used for automatic complete filling and emptying of the cooling water circuits, simplifying the maintenance of the system.

For customer requirements that cannot be covered by the DmRC-C-900-24-KIT, our thermal management specialists at AMS Technologies are happy to develop a completely tailor-made solution and offer all services from development through to series production.
