Liquid to Liquid Thermal Management Assemblies

Liquid to liquid thermal management assemblies like our range of water cooling pump stations , 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.

Water cooling pump stations 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.

Used in marine applications, for data center cooling or in energy transmission HV applications the liquid-to-liquid cooling systems feature utmost reliability thanks to a unique manifold block, a pressurized loop, selected materials and redundant pumps, temperature control via 3-way-valve, short commissioning time, automatic de-aeration, leakage monitoring and PLC control.

Turbo compressor recirculating chillers are used to cool water to temperatures between 10 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 the eChillers achieve an all year 20 to 30% reduction in energy consumption. The turbo compressors operate at up to 88.000 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 they are the ideal solution for data centers, energy storage and many industrial applications.

Water cooling pump stations

Our pump stations are available in 3 series: M, C and L. The M series has a footprint of 400 x 600, is mounted on an open frame and is available as single or double pump system with up to 120 lpm. The C series requires a minimum footprint of 600x600 and is available for up to 750 lpm, mounted in open frames or into a cabinet. The L series is used in energy transmission facilities for static var compensators, STATCOMs or HVDC. They are equipped with a water treatment loop that keeps deionized water below 0,1 µS/cm and often fully redundant systems are required. Flow rates range from 200 lpm up to 10.000 lpm.

Battery cooling pump station

Energy storage systems require moderate temperatures even in high ambient temperatures. For battery cooling applications the B series is equipped with a compressor, i.e. an additional refrigeration cooling loop, and a larger storage tank. Cooling capacity is up to 200 kW and flow rates of up to 750 lpm are available.

LCS cooling systems

Our LCS cooling systems are available with 20 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. The single stage versions allow for return water (of facility water or from air blast coolers) temperatures of 25 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. A 120 kW model will be available in 2021.

The eChiller 35 and 45 models are installed into a cabinet of width 1300 mm, height 1980 mm and depth 700 mm. The dry weight is 510 kg. For operation 60 liters of tap water (refrigerant R718) are added. 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.
