ERW ax Liquid Chillers

RW ax systems for industrial refrigeration of process fluids (water, water and glycol) are air-cooled: the only resource used is therefore electrical energy, a decisive advantage in contexts where it is advisable to save water (because of its cost or scarcity). The IP54-grade machine protection (against dust and other agents) facilitates their installation in outdoor environments, which is also possible at temperatures up to +40°C and above, at the customer’s request. RW ax liquid chillers from Frigofluid are suitable for achieving average fluid outlet temperatures (between +1°C and 20°C), with excellent control of the resources used for their operation.

The secret of this system is the combination of the refrigeration section and the free-cooling section depending on the time of day and year: the first mode allowed by these liquid chillers takes advantage of the normal operation of a refrigeration circuit, the second allows cold outside air to be directly conveyed to the fluid to be cooled: maximum efficiency, minimum energy use due to the clear separation between the two sections.

Low outlet fluid temperatures (water or water and glycol, down to -8°C) characterize RW ax LT liquid chillers: air condensation ensures that they use are electrical energy, and not water, for their operation: a resource that is then optimized by the electronically controlled “brushless” type axial fans. Up to +40°C ambient temperature allowed in standard execution.

Liquid chillers for low temperatures, also in outdoor environments The RW CW series of process fluid coolers (water, water/antifreeze) are water-cooled and operate with environmentally friendly gas compression. They allow cooled liquid temperatures between -8°C and +20°C. In standard design, ambient temperatures of up to +40°C are permissible, but in the “RW ax/HTA” version even higher ambient temperatures can be achieved. IP54 degree of protection as standard, allowing outdoor installation without a protective roof.
