A complete, high-performance water chilling plant: that was the need of a company in the Brescia area active in the processing of semi-finished metal products. Frigofluid supplied three chillers, a dry cooler and the complete installation by drawing on its expertise in the sector and exploiting group synergies. One plus: energy efficiency.
Refrigeration systems for the metal oxidative treatment industry often have to meet a peculiar requirement: very low output temperatures. This was no exception to a metal treatment company in the Brescia area, which was served with a true turnkey water chiller system.
Chillers were supplied in conjunction with Frigofluid dry coolers: this is because production lines of the same company may be served by different machinery, with different output temperatures. In this case, the line served by two chillers gives fluid output temperatures (water and glycol) of 7°C.
Some technical notes on the industrial chillers supplied: these are two RWE 730/4 ax-ST chillers, equipped with cooling capacity of about 700 kW and four refrigerant gas circuits (R410A, efficient and very safe). Finally, a hydraulic distribution system, nstalled on site with supervision by Frigofluid personnel, is also part of the supply.
A plus of the plant: high energy efficiency, enabled especially by the use of machinery with different technical-functional characteristics depending on the process line supported.

These liquid chillers combine efficiency and performance control with brushless axial fans: they are chillers suitable for achieving average fluid outlet temperatures while optimizing energy use. In standard execution, ambient temperatures up to +40°C are allowed, but set-ups for even higher ambient temperatures can be requested.
How to cool process fluids in the total absence of water? By employing industrial air coolers, or “dry coolers,” such as Frigofluid’s RAW/E series: simple, environmentally friendly, low acquisition cost.
This is a classic industrial refrigeration application: often, metalworking chillers operate on several production lines in the same plant, with different temperature ranges and different outlet fluid temperatures. It is not infrequent that a complete cooling plant is also supplemented by temperature control units: these are useful for keeping the temperatures of the process fluids constant, according to preset values.
There is Frigofluid's signature on the refrigeration of Almag's production processes: an opportunity to strengthen relations with a large company in the Brescia area, recognized worldwide. Two industrial chillers and a dry cooler were supplied to the company.
