Castel is a leader in the sector of components for refrigeration and air conditioning: an entirely family-run Italian company that has grown and consolidated since 1961 thanks to a marked search for innovation and a constant desire for national and international commercial expansion. Castel has been recognised as one of the best factories in the mechanical sector for over fifty years: the quality of its products is recognised in Italy and worldwide.

Castel products of controlled origin are synonymous with innovative capacity, attention to detail and serious customer service. Its solid and proven production organisation, its working environment and the enhancement of human resources, perceived by the company as the fundamental ingredients of success, are the ideal environment within which experience meets creativity.

The wide range of Castel products includes: thermostatic and electronic expansion valves, solenoid valves, coils, connectors, safety devices, water pressure switches, pressure regulators, indicators, dehydrating and mechanical filters, oil level control systems, taps for refrigeration systems, anti-vibration mountings, brass fittings and connections and charge valves.

Solutions for all refrigerants

The PolyHedra line on display at Refrigera 2019

In step with the transformation the HVAR sector is currently undergoing, Castel has brought new product lines to the market. The PolyHedra line presented for the first time at MCE 2018 is now complete and includes components to meet the needs arising from the use of HC, HFO and R32 flammable refrigerants: high pressures and high discharge temperatures from the compressor, as well as safety of use.

The Green line, on the other hand, is exclusively dedicated to CO2 and therefore includes components designed to work at the high pressures typical of this gas, from small taps with 60 bar PS to taps with 140 bar PS, in copper, K65, steel. The Green line offers components suitable for all technological applications, including heat pumps, commercial refrigeration, civil or industrial air conditioning systems and transportation.
