Frigotherm Ferrari has been one of the main points of reference for refrigeration and air conditioning for over 50 years. "70% of our market is in Italy. We have extensive experience in the apple sector, but also provide innovative solutions to other operators as well as to the logistics sector," explains sales representative Stefano Tasinato.
Solutions adopted by Frigotherm Ferrari
"We set up refrigeration and air conditioning systems, heat pumps and automation systems for the food, industrial and process cooling sectors. The size of our company means we can be reliable, flexible and customer-oriented. Constant and intensive training of our operators is reflected in the high-quality of our solutions."
"A team of highly-skilled technicians will be at your side from the first consultation to after-sales assistance. Our solutions are made to measure and employ modern reliable technologies. Our team boasts 12 consulting and design experts, 10 assembly and installation managers, 18 service specialists, 6 panel and electrical installation technicians, 8 PLC and SCADA software programmers and 5 administrative operators."
Different types of refrigerants
Ammonia systems (NH3) have always been employed by Frigotherm Ferrari. The need to protect the environment from greenhouse gases is leading towards the use of natural refrigerants, including NH3. Its characteristics make it suitable to be used in industrial cooling cycles as the cooling power, therefore the energy efficiency attainable, compensates the investment.
To reduce the risk connected to the use of NH3, the refrigerant charge is reduced to a minimum. Low-charge chillers or indirect cooling chillers are developed where ammonia is confined to the refrigerating unit and is used to cool the vector fluid. The objective is to develop safe, reliable and efficient systems with a low environmental impact.
Carbon dioxide (CO2) is a refrigerant with excellent thermodynamic characteristics and a low global warming potential. "Over the past few years, we have developed various industrial applications that use CO2 both during a sub-critical and trans-critical phase, as primary refrigerant and/or as heat carrier fluid."
Other solutions are propane, a natural gas whose flammability means the charge must be contained and explosion-proof electrical components must be used, and synthetic refrigerants with a low GWP known as HFOs. The thermodynamic characteristics of these mixes mean they do not perform as well as natural refrigerants, which are to be preferred if possible.
