Standard units
We have developed a range of standard units that can be purchased as-is or used as a foundation when we build a customized solution. The collection is called EcoChill and is available in three sizes.
EcoChill Collection
Unit package with a Bitzer screw compressor and ammonia as
refrigerant, ensuring energy-efficient and reliable operation.
These robust and future-proof units offer easy service and
customization options to meet various cooling requirements.
Reliable and proven solutions
With an advanced control system and carefully selected components, ensuring reliable and energy-efficient operation for many years.
Robust design and easy service
Designed for high performance and long service life, the units offer a robust construction that is also easy to maintain and service.
Future-proof and environmentally friendly
Thanks to ammonia as refrigerant, EcoChill Mono NH3 is a sustainable solution that is not affected by future refrigerant regulations or restrictions. Therefore, you can trust that an investment in an EcoChill is future-proof.
Flexible capacity adjustment
The units are designed to communicate with each other, enabling efficient capacity control when multiple units are required in the facility. The compressors are frequency-controlled for optimal performance and energy consumption.
Model range and customization options
8 models to choose from:
- 4 for AC
- 4 for refrigeration
Customization possible for deviating cooling requirements.
Quality-assured performance
All units undergo comprehensive testing in our factory. If required, we can also offer factory testing as an option.
