Features
Advantages
Wide operating range

This series of CO2 subcritical reciprocating compressors is suitable for use in a wide range of applications, guaranteeing reliable, safe and efficient operations in subcritical processes.

High safety

The use of CO2 natural refrigerants guarantees high safety standards and reliability, thanks to their many features. Non-flammable and chemically inert at low concentrations, they feature a very low GWP and lower air emissions, for the utmost respect for the environment.

Low oil carryover

SK3 series reciprocating compressors are designed to guarantee low oil carryover, minimising losses and providing high protection and lubrication for all moving parts. This guarantees optimal, high-quality operation, which also ensures maximum efficiency and the highest performance.

High standstill pressure (SSP)

The high standstill pressure (SSP) of all reciprocating compressors in the SK3 series allows the best management of plant downtime pressure, guaranteeing perfect maintenance and a quick start-up, without having to use active or passive systems.

Compact and quiet design

Frascold subcritical reciprocating compressors are unique in their lightness, compactness and quietness, which allows them to be used in a very wide operating range and also in small systems.

Partnership - Frascold, Friul Frigo, Villa Food
An all-in-one CO2 industrial system by team Friul Frigo and Frascold

A turnkey system that successfully combines performance and respect for the environment to respond to the LT and MT refrigeration and conditioning needs of the new Villa Food production site, dedicated to the creation of ready-made meals: this was the challenge won by Friul Frigo and Frascold. The work plan entailed a study of the layout, the sizing and development of the chilled and controlled temperature areas of the plant.
