Serfriair SFR Range has been designed to meet the demands of industrial processes that require chilled water production. Our range of water chillers is designed specifically for injection molding machines, extrusion and blow molding.
In the industry increasing production flexibility is required. A water cooler is another component in the chain, but never should determine the pace of work or cause a shutdown. Therefore, both the quality and the response of the after-sales service in front of a breakdown are paramount.
In case of major breakdown, have machines in stock is essential to quickly respond to any request for replacement. In order to have an acceptable stock, machines must bring all embedded options.
Our machines come with hydraulic kit included (tank + pump + expansion tank), water bypass and all options integrated in the cooling circuit (LP and HP gauges, condensation control, etc…).
Heat Exchanger unique design
The quality of a water chiller depends on the type of evaporator used. SFR range incorporates an patented water/freon exchanger. This is an exclusive design (immersed in water tank) with much exchange surface.
By design, the machine can work with a return water temperature much higher than that required by traditional plate or multitubular exchangers. It is very robust, so that resists corrosion of water (dirt or lime) and, if frost is not deformed. Its design also eliminates the need for an external water tank.
To prevent short cycling of compressor operation, the evaporator has a water capacity in line with the cooling capacity of the chiller.
The SFR range, from 5 to 802, is certified PED-H-73 (Directive 97/23/EC of May 29, 1997) and, of course, incorporates the latest technology in components: Copeland SCROLL compressors, Danfoss expansion valves, etc…
Therefore, these machines have an optimal COP (efficiency) and offer optimal results far superior compared with Asian models.
