CoolNat - ZIEGRA
Ice machines with natural refrigerants for consultation
The best for food:
Food deserves only the best when it comes to handling. Above all, absolute freshness - and preferably natural and environmentally friendly.
This is exactly how ice machines from the ZIEGRA CoolNat series produce the best broken ice.

The refrigerant CO2 (R744 - carbon dioxide) is being used more and more frequently in refrigeration systems for the food sector. Supermarkets are currently increasingly using ice makers connected to a CO2 refrigeration network, and the same trend can be seen in other sectors.
CO2 has two main advantages as a refrigerant:
- Environmentally friendly: The refrigerant has no ozone depletion potential and only an extremely low greenhouse effect (GWP of CO2 = 1 / for comparison: GWP of R134a = 1430)
- Efficiency: Compared to other refrigerants, the efficiency of a CO2 compound is usually significantly better thanks to physical conditions, so the same ice output can be generated with less energy input (improved COP)
ZIEGRA is already known worldwide for its environmentally friendly ice makers; in line with this philosophy, we have developed this new CO2 product line to market maturity.
Take a look at the wide range of ZIEGRA ice machines with CO2 as a natural refrigerant.
The ZBE 350 EV to UBE 15,000 EV ice makers with a daily output of 350 to 15,000 kg cover the ice requirements of many applications. They are specially designed for the pioneering technology of a CO2 refrigeration system. You can find more information on our environmentally friendly CO2 ice makers in our ZIEGRA CoolNat CO2 brochure.
We will be happy to find the perfect solution for your project - we look forward to hearing from you!
