CO₂ multi compressor packs



SCHIESSL is your specialist for subcritical R744 systems with extremely high robustness. CO₂ systems are environmentally friendly, energyefficient and future-proof.

From food refrigeration to air conditioning, CO₂ is used in a wide range of installations. The adaptability of this refrigerant makes it the ideal choice for various industries. In the commercial refrigeration industry, CO₂ has established itself as the standard refrigerant and is increasingly replacing synthetic refrigerants in both larger and smaller capacity ranges.

CO₂ is characterized by a very high volumetric cooling capacity, which is about 5 to 8 times higher than that of NH₃, which allows the use of smaller compressors for large cooling capacities. The challenge with CO₂, however, lies in its high pressure requirement and a critical temperature of just 31 °C (74 bar).

We have focused our in-house production on water/brine-cooled systems that are always operated in the subcritical range. F o r transcritical solutions, we work together with renowned external suppliers. Our experts have many years of experience and guarantee the highest quality.

 

 

Advantages

Environmentally friendly: CO₂ is a natural refrigerant that has no negative impact on the ozone layer and has a low greenhouse effect. The use of CO₂ as a refrigerant actively contributes to environmental protection.

Energy efficiency: CO₂ is extremely efficient and enables significant energy savings. This leads to lower operating costs and an improved environmental footprint.

Versatility:  CO₂ is used in a wide range of installations, from food refrigeration to air conditioning.

Safety: CO₂ (R744) is neither flammable nor toxic.

Cost-effective: CO₂ refrigerant is very cost-effective and does not require recycling or disposal
