This type of system is ideal when it is necessary to refrigerate several cold rooms at different temperatures above zero.
Typically used in slaughterhouses, this system is equipped with different pre-cooling rooms, each dedicated to a different type of meat (pork, sheep, goat, horse…).
In our past projects, the HFC refrigerant gas was only and exclusively present inside the refrigeration plant, which cools the glycol, with the advantage of minimizing the amount of refrigerant and the possibility of possible leaks.
When using potentially dangerous gases (e.g. ammonia, hydrocarbons, etc.) we believe it is even more advisable to use a glycol refrigeration system to keep the circuit containing the refrigerant gas away from areas open to the public.
The glycols we commonly use at Friostar are:
– Ethylene glycol, the most cost effective and widely used fluid for heat exchange.
– Propylene glycol, used for food grade applications, as it is less toxic than ethylene glycol
The glycols are then skillfully mixed with water in various percentages, depending on the degree of protection against freezing required, allowing these solutions to be used in a temperature range ranging from -45°C to +120°C.
All systems are designed and manufactured to always guarantee:
- Compliance with established budgets
- Meticulous attention to detail
- High quality materials
- Long lasting durability
- Ease of use
- High energy efficiency
- Reduced operating costs
- Efficient, productive, and safe working conditions
