The SENNA Xtra Smart refrigeration booster offers excellent value-for-money in medium and large format retail stores, while retaining the well-known Enex quality and reliability, using highly sustainable R744 refrigerant. Thanks to its narrow width (850mm up to 200kW), it is ideal in retrofit applications. With up to 6 medium temperature and 5 low temperature compressors, the unit can be configured with several efficiency enhancing solutions, such as parallel compression, liquid and vapor ejectors and permanent magnet compressors. Suitable for indoor or outdoor installation with optional cladding, it can be also delivered as a plug & play monoblock unit, mounted on a skid with an integral gas cooler and complete with refrigerant piping and electrical connections.
