CO2 - SUBCRITICAL SERIES

Frascold SK3 reciprocating compressors are recommended for use with CO2 natural refrigerants and are the perfect solution for the commercial, industrial, and process cooling sectors.

The models in this series are suitable for single-phase, booster, and cascade systems and have been designed to withstand high plant downtime pressure. This helps provide lower maintenance efforts and the perfect start-up sequence to protect vital components.

The particularly strong construction of the compressors allows them to operate with evaporation temperatures down to -50°C (-58°F) and with condensation temperatures up to 20°C (68°F). With the latest technology built-in, great performance and enhanced safety features are achieved in a single package.

Features
Advantages
Wider Operating Ranges

This series of CO2 subcritical reciprocating compressors are perfectly suited for use in a wide range of applications and provides reliable, safe, and efficient operations in subcritical processes.

Higher Degree of Safety

The use of CO2 natural refrigerants guarantees high safety standards and reliability. Non-flammable and chemically inert at low concentrations, they feature a very low GWP and lower air emissions, lessening environmental impacts.

High Efficiency with Low Oil Carryover

SK3 series reciprocating compressors are designed to guarantee low oil carryover, minimizing losses, and providing high protection and lubrication for all moving parts. This provides for an optimal operation level and ensures maximum efficiency and the highest performance levels possible.

High Standstill Pressure (PSS)

The high standstill pressure (PSS) of all reciprocating compressors in the SK3 series allows for the best management of plant downtime pressure—providing easier maintenance and a quick start-up without having to use active or passive systems.

Compact, Quiet Design

Frascold subcritical reciprocating compressors are unique in their lightness, compactness, and reduced noise levels making them ideal for tight spaces and the widest range of applications.

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.
