Refrigeration plants with ammonia

A sustainable solution for industrial refrigeration

Refrigeration plants with ammonia have a high cooling capacity. This is particularly advantageous for industrial applications that require refrigeration at low temperatures, such as freezing rooms and blast chilling tunnels.

The advantages of refrigeration plants with ammonia

Refrigeration plants with ammonia offer several advantages compared to conventional systems. It is essential to design and operate these systems with extreme caution, due to the toxicity and slight flammability of this fluid. On the other hand, ammonia has a high cooling capacity that allows very low temperatures to be reached. This is particularly advantageous for industrial applications that require refrigeration at extremely low temperatures, such as freezing rooms and blast chilling tunnels.

Natural coolant fluid

Outstanding thermophysical properties

High energy performance coefficient

Does not contribute to the greenhouse effect

Does not damage the ozone layer

The Stefani proposal

Stefani offers a selection of machines dedicated to plants using ammonia as a coolant fluid. The distinctive feature of all these machines lies in their construction system, which uses a heat exchange coil made of stainless steel with aluminium fins.
