Liquid to liquid thermal management assemblies like our range of , energy efficient and environmentally friendly turbo compressor recirculating chillers or our LCS cooling systems are the ideal solution when water or water-glycol mixtures are used to cool power electronics or energy storage systems.
LCS cooling systems
Our LCS liquid to liquid cooling systems are available with 20 kW and 150 kW cooling capacity. The LCS cooling systems are used in systems with different materials including copper.
Turbo compressor recirculating chillers
Our turbo compressor recirculating chillers are available with 35 kW and 45 kW of cooling capacity, both in one- and two-stage versions, as well as with 120 kW of cooling capacity. The single-stage versions allow for return water (of facility water or from air blast coolers) temperatures of +25°C to +30°C, whereas the two-stage versions have an extended range of up to +45°C. The turbo compressors themselves can be speed-controlled such that they can be operated at partial load conditions down to 50% of their maximum capacity.
The eChiller 35 and 45 models are installed into a cabinet of 1300x1980x700 mm WxHxD. The dry weight is 510 kg. For operation 60 liters of tap water (refrigerant R718) are added. The eChiller 120 model comes installed into a cabinet of 2015x1932x900 mm WxHxD. Standard features are PID control, communication interfaces to upper control system and peripheral components and a fully integrated free cooling process. Optional features are master-slave control, remote control and monitoring. The chillers may be connected to outdoor air blast coolers.
AMS Technologies’ broad range of liquid cooling components includes high-performance, liquid-cooled cold plates, available in a wide variety of materials, dimensions and cooling capacities, as well as fin heat exchangers in various sizes comprising metal tubes expanded into fins for good heat transfer to the surrounding air.
For slightly lower heat loads, our liquid to air thermal management assemblies like our range of recirculating chillers, OEM liquid cooling kits, ambient cooling systems or liquid-based cabinet coolers provide ready-to-use solutions for removing heat from laser systems, power electronics or industrial processes and dissipating the heat to the ambient air.
are used whenever a secondary coolant circuit is needed that protects heat sources from contamination, is temperature-controlled to prevent too cold temperatures and condensation or provides electrical isolation on high-voltage equipment. The secondary loop is cooled by primary raw water, i.e. ship water, facility water, sea water or district cooling water.
Turbo compressor recirculating chillers are used to cool water to temperatures between +10°C and +28°C, ideally around +20°C, and meet the demand for increased energy efficiency and environmental friendliness. Tap water is used as refrigerant – normal water, which is known to be the fluid with the highest enthalpy of evaporation. Utilizing this natural source together with the integrated “free cooling” process control, turbo compressor recirculating chillers achieve an all year 20% to 30% reduction in energy consumption.
The turbo compressors operate at up to 88000 rpm – the low density of steam at +20°C/20 mbar requires a high volumetric flow, but at comfortable low noise levels of below 50 dBA. The systems are assisted by integrated small vacuum pumps that compensate eventual and harmless leaks. Maintenance and leakage control as known from refrigeration systems charged with kilograms of environmentally unfriendly refrigerants become obsolete. Currently available for stationary applications, turbo compressor recirculating chillers are the ideal solution for data centers, energy storage and many industrial applications.
