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.
Almag – Azienda Lavorazioni Metallurgiche e Affini Gnutti – manufactures brass bars for turning and stamping: it is based in Roncadelle (Brescia) and is now the second largest company in the world for the manufacture of high quality semi-finished bars. Among the sectors its products and services address: construction, automotive, and electromechanics.
Elasticity, precision and innovation: these are the values that have inspired the company since 1946 in its workings: the last twenty years with the contribution of Frigofluid’s refrigeration technologies.
Production at the Roncadelle plant includes the processing of brass alloys by extrusion process.The company commissioned Frigofluid to provide a refrigeration system for the process liquids (water plus glycol) connected to the presses.
The following were selected:
The capacity of the unit supplied to Almag reaches 2.7 MW for the press section alone. The temperature of the process fluid output, according to customer requirements, is 20°.
All this with significant energy savings, thanks to the combination with appropriate separate free cooler: quantifiable up to 80% lower than installations without the “free-cooling” device.

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.
The biomass sector is one of the most interesting for its implications related to energy recovery: Frigofluid supplied an industrial chiller to an international broker, with final installation in Colombia.
