Bitzer is now offering a range of compressor units for use with the natural refrigerant ammonia (R717). The Bitzer ammonia compressor packs (ACP) are available with a capacity range of 100 to 450 TR. The modular compressor units comprise up to three compressors. For higher capacities, as many as three compressor packs can be connected (up to 9 compressors) and connected to a single controller, increasing the overall capacity up to 1,200 TR. The company says this is ideal for industrial systems.
Johnson Controls introduced the Luxaire® Ovation™ Ultra High Efficiency Packaged Unit. The combination of the unit’s two-stage compressor, VFD, high-efficiency indoor/outdoor coil, and premium-efficiency indoor/outdoor motor, delivers up to 18.1 SEER and 14.35 EER.
Bitzer’s Oribt 6 Series Scroll Compressors for R410A are based on the design of the company’s Orbit 8 Series Scrolls. The 6 Series is designed for applications ranging from 10-20 HP, and according to Bitzer officials offers market leading energy efficiency and the lowest sound levels in their class by 2 – 4 dB(A).
Danfoss will extend its inverter scroll compressor range VZH to include three new models. According to the company, the variable speed VZH compressors provide efficiency at part-load conditions, and can improve efficiency by more than 30% compared to fixed-speed compressors.
Bosch Thermotechnology has launched its new LM Series water-to-water (W2W) heat pump line for new commercial and retrofit applications. The LM Series includes five models from 2 to 6 tons. They can be used in horizontal and vertical configurations depending on the application, and feature a two-speed scroll compressor and a commutated motor as standard components for efficiency and comfort. They achieve up to 32 EER part load and up to 22 EER full load.
Bitzer says its new Ecoline reciprocating compressor series is now more versatile and available for use with R134a, R404A, R407A, R407C, R407F, and R507A. With the new series, the company claims it is transferring all the advantages of the Ecoline series for R134a refrigerant to an even broader range of applications.
