Cooling capacities from 1kW to 300kW
Self-contained systems with heat exchanger, coolant storage tank and pump.
Water-to-water cooling systems utilise chilled house water to remove heat from process coolant. They provide a barrier thus protecting your process coolant from potentially harmful cooling water that may be contaminated by corrosion, bacteria, or may simply not be compatible i.e. oil — water, ultra pure deionised water - water. They are ideal for high heat load applications where precise temperature control is needed and chilled house water is available. The LR & LB range of self-contained water-to-water heat exchange units is 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.
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.
A wide range of non-ferrous/stainless steel pumps with varying flows and pressures are available to suit the customer's requirements. Pumps are of positive displacement or centrifugal mono-bloc construction with fan-cooled electric motors having class E or F insulation. A coolant tank of adequate capacity including a generous ullage allowance for drain-back is incorporated within the cabinet. The coolant circuit is completely non-ferrous including copper pipe, two ply reinforced SBR hose and appropriately sized BSP female fittings for inter-connection to external process.
Bolted construction from pre-fabricated panels generally manufactured from polyester powder coated, Zintec steel with semi gloss finish. Assembled using BZP fasteners. Sufficient working space envelope and easy access panels allow safe, trouble free maintenance.
