BITZER Orbit 8 Scroll compressors are now available for use with R410A.  With capacities from 39 kW to 103 kW, they are designed primarily for air and water cooled rooftop air conditioning and chiller OEM applications.

The compact size and lightweight of the Orbit 8 Scroll compressors is a major advantage.  They are claimed to be up to 10% lighter than competitive models across large parts of the range (25, 32, 35 + 40 HP models), as well as having a market leading low operational sound level which is some 3dB (A) lower than the comparable competition.  They also offer industry standard interchangeability in terms of capacity ratings, footprint and fittings/connections across the range.

The Orbit 8 Scroll scores well under Integrated Part Load Value (IPLV) and European Seasonal Energy Efficiency Ratio (ESEER) performance criteria which take into consideration seasonal operating conditions and weight different key operating features to promote energy efficient operation.  For superior lubricity and performance reliability, PVE oil, compatible with HFC refrigerants, is used.  The low oil circulation rate means higher efficiency at the heat exchanger and higher reliability as the oil stays inside the compressor.

The Orbit 8 Standard Scroll is for high condensing temperatures and is optimised for air cooled chillers.  The Orbit 8 Boreal is optimised for low condensing temperatures and ideal for water cooled chillers.  Tandem and trio systems are also available.
