Destinations of use, intended and unintended use
Keyfrost refrigeration equipment is agri-food machinery (MACHINE DIRECTIVE 2006/42/EC), intended for treatment
of food products.
The machine is intended for the preservation of “fresh“ foodstuffs and/or products at the temperatures indicated in the technical documentation.
It was designed to be able to work at room temperature from 0°C to +43°C (class T).
It was designed to maintain a certain temperature in a cold room designed for such use.
The machine is not intended to be installed and used in cells located outside.
The machine is not intended to be installed and used in an atmosphere at risk of explosion.
Any use outside the permitted ones is considered “improper use“ and therefore the manufacturer disclaims any responsibility for it.
The unit is not intended to be used for the storage of products that develop corrosive substances.

External motor capacitor unit.
The load-bearing body made of galvanized steel sheet, with powder coating for protection from the elements.
The easily disassembled paneling for convenient access to internal components.

Inside the unit are housed:
• Electric motor-driven hermetic compressor with thermal protection or motor-driven semi-hermetic compressor
electric with thermistor protection. Mounting on anti-vibration elastic supports.
• Capacitor consisting of copper tubes and aluminum fins blocked by mechanical expansion of the tubes.
• Directly coupled axial single-phase fans with protective grille according to UNI EN 292/1
• Painted steel liquid receiver
