GA: Bitzer launches Orbit 6 Series Scroll Compressors for Light Commercial Applications

Bitzer’s Orbit 6 Series Scroll Compressors for R410A are based on the proven design of its popular Orbit 8 Series Scrolls. The 6 Series is designed for applications ranging from 10-20 HP and, like the Orbit 8 models, are very robust and offer market leading energy efficiency and the lowest sound levels in their class by 2 – 4 dB(A).

Designed for both A/C and heat pump applications, they offer high power factors and have a large application range (from a SST of -4°F to a SCT of 122°F) and a high condensing temperature limit up to a SCT = 155°F.

Bitzer‘s new patent pending Advanced Header Technology for uneven Scroll compressor tandems and trios provides multiple compressor combinations for OEMs designing their next generation systems. Taking advantage of the unique design characteristics of the Orbit series, including an isolated oil sump
design and good miscible PVE oil, Bitzers’s Orbit series has exceptionally low oil carry-over rates. The Advanced Header Technology then operates by ensuring that small differences in pressure drop in header tubing does not impact oil balance between compressors in low mass-flow situations like those found in many air-to-water heat-pumps.

The result is a powerful combination of benefits for OEMS. A single header package can be used for up to 20 different capacity combinations resulting in lower inventory costs. Uneven tandems can be selected to maximize full load, part-load or other customer requirements. Addtionally, Bitzer’s advanced header technology does not require internal restrictor washers that can be difficult to manage on the production floor and, therefore, works well with many OEMs’ lean production systems.
