Refra‘s range of CO2 transcritical boosters consists of two compact frame types and a standard customizable frame that suits customer needs:
Smallest and lightest type is called “Light”. It can be up to 50 kW of refrigeration capacity split between medium temperature and low temperature refrigeration. Enclosure limits the system to 3 compressors. It can be either 2 (MT) + 1 (LT) or 3 (MT) + 0 (LT) configuration.
- Compact and light frame
- Up to 3 compressors (50 kW of MT and LT refrigeration capacity)
- Up to 50 L receiver
- Outdoor installation
Second of compact frame type is called “Vertical”. This is because of its design of being built upwards to reduce the footprint, but maintain the same composition of elements as the Refra standard customizable CO2 booster. This type of frame can be used for up to 4 compressors and provide up to 100 kW of refrigeration capacity. Configuration can be: 4 + 0, 3 + 1 or 2 + 2 compressors, medium temperature and low temperature respectively.
- Compact and robust frame
- Up to 4 compressors (100 kW of MT and LT refrigeration capacity)
- Up to 75 L receiver
- Option for outdoor installation
Standard customizable CO2 transcritical booster rack can be as small or as big as required. This kind of product can be used for most types of supermarkets, other commercial application or industrial applications. It is built on a rigid frame, designed for easy maintenance and durability. Refrigeration capacity provided can be from 50 kW to 1 MW or more.
Customization of products doesn’t end with refrigeration capacity of compressor amount changes. Technologies like parallel compression, liquid injection, optimization with internal heat exchangers, different capacity regulation solution etc. can be implemented and adapted for each individual rack Refra builds. Different control systems are available, like Danfoss or Carel.
- Robust frame designed individually
- Delivers the refrigeration capacity that is required (MT and LT)
- Option for multiple receivers
- Option for outdoor installation as a “Reach-In” type or a container solution
