Description
Cooling capacities from 1kW to 300kW
Fluid to Fluid Heat Exchangers
Self-contained systems with modulated primary supply, fluid to fluid heat exchanger, coolant storage tank, and pump.
Description
Our closed loop fluid to fluid exchangers utilise chilled facilities water to remove heat from the process coolant via a heat exchanger, providing an efficient way to cool without the need for additional refrigeration plant. They provide a barrier thus protecting your process coolant e.g. ultra-pure deionised water or other thermal transfer fluids that are incompatible with water. Our units also overcome problems associated with insufficient pressure, fluctuating flow or very cold water by providing a stable supply of coolant to your process regardless of the facilities water condition, thus ensuring your process remains at optimum performance.
The LR & LB range of self-contained water to water heat exchange units are fully packaged, self-contained, and complete with heat exchanger, pump, coolant reservoir and all necessary controls. The LR range is suitable for mounting in standard 19″ racks or bench top location whilst the LB range is free standing.

Heat Exchangers
This usually takes the form of a plate heat exchanger with a matrix of corrugated plates. Dependant on the size requirements, the individual plates will be either brazed together or sandwiched between two heavy end plates and pulled together by tie bolts. Supplied in 304 & 316 stainless steel as standard and Titanium for more aggressive applications.
Water Circuit
A wide range of non-ferrous/stainless steel pumps with varying flows and pressures are available to suit thecustomer’s requirements. Pumps are of positivedisplacement or centrifugal mono-bloc construction with fan-cooled electric motors having class E or F insulation. A coolant tank of adequate capacity be either brazed together or sandwiched between two heavy end plates and pulled together by tie bolts. Supplied in 304 & 316 stainless steel as standard and Titanium for more aggressive applications.
