Installed products

In the cold store anteroom: the cold cycle is maintained and ambient humidity is reduced with 3 Zefiro double-flow air coolers, for a total of 60 kW cooling capacity.
In order to minimise the overall dimensions, it was decided to use machines that are very close to the ceiling, while, to guarantee efficient condensate drainage, it was decided to insert particularly inclined tanks.
In the positive temperature cold rooms, 0°C: 6 Grecale 560 industrial cubic air coolers, for a total of 360 kW cooling capacity
The machines used are very compact and are characterised by optimised ventilation, guaranteed by a specially sized plenum.

In the negative temperature cold rooms, -25°C: 4 Grecale 800 industrial cubic air coolers, for a total of 240 kW cooling capacity.
These industrial cubic air coolers provide a reduction of 1°C every 5 minutes.
Remote condenser: 1 Scirocco condenser for a total of 400 kW heat exchange.
This condenser guarantees a standard level of silent operation, with 55 dB(A) at 10 metres.
It is a “contact free” system, offering excellent reliability against leakage and requiring a low refrigerant charge.

Advantage obtained

Thanks to our machines, the system is able to maintain the cooling cycle with excellent energy efficiency.

A delicate order, managed thanks to the collaboration with an important and loyal customer who, over the years, continues to choose our products to create high performance systems characterised by very high quality.
