The new Bitzer Orbit+ models enable system manufacturers to fulfil the requirements of the European Ecodesign Directive. They are equipped with a line start permanent magnet motor, which achieves unmatched efficiency levels that improve the seasonal performance (SEER/IPLV) by up to 8 per cent while also increasing cooling capacity by up to 5 per cent.
Additionally, Orbit+ compressors can replace or be combined with standard Orbit models without redesigning the system significantly. Tandem and trio combinations can be easily tailored towards system capacity and efficiency targets according to the customers’ specific needs and annual load characteristics. For even better capacity modulation, customers can add a frequency inverter like the Bitzer Varipack.
All Bitzer Orbit models are designed to work with R410A as well as the most recently introduced low-GWP refrigerants, such as R454B and R452B, which belong to the A2L category. Similar to the Orbit 6 and 8 series that have already been introduced, the new Orbit+ models are able to operate with a frequency inverter at 35 to 75 Hz while performing with a low sound level and industry-leading low oil carry-over rate. They are interchangeable, thus allowing systems designers and manufacturers to simplify development work by using existing frameworks, footprints, piping layouts and manufacturing processes, which results in reduced complexity and operating cost as well as a quicker time to market for new systems. Orbit scroll compressors operate at peak efficiency despite demanding conditions, helping to reduce system footprints thanks to their compact size and unique compound solutions.
Orbit scroll compressors were developed especially for air-conditioning and heat pump applications. They are easy to install, offer high energy efficiency when fully or partially loaded and have the lowest noise emissions in their capacity class. What is more, the energy consumption is extremely low, especially at low condensing temperatures where the Orbit Boreal series can be applied.
So far, users have been able to choose from two families: Orbit 6 and Orbit 8. For increased market requirements, such as F-gas Regulation and Ecodesign Directive, Bitzer has developed the new Orbit+ series with high efficiency motor technology and Orbit Fit with economiser technology.
