UK: BITZER Advanced Header Technology (BAHT) for tandem and trio Orbit scroll compressors makes it easier to use these products in parallel circuits for air conditioning and heat pump systems. The newly developed suction gas header with integrated oil distribution plays a key role, specifically directing oil to one of the compressors in the tandem and trio units. The system even works when uneven compressors are combined and allows the frequency of a single compressor to be adjusted.
The benefit of BAHT is that only one suction line is required for many compressor combinations. The system functions with consistent reliability at high and low suction gas volume flows and promotes uneven capacity adjustment through different displacements and compressor housing sizes in one unit. Another benefit is that active oil management with an oil separator is no longer necessary for distributing the oil. Even when a compressor is shut off, oil distribution is maintained in the unit.
BITZER’s ORBIT 6 scroll compressor range comprises five models with cooling capacities between 27 and 51 kW. They are ideal for air conditioning systems and heat pumps, featuring low sound levels. The larger ORBIT 8 series has six displacement volumes between 29 and 77 m3/h with 15 to 40 hp outputs. The sound level is about three dB(A) lower than that of conventional compressors. The very low oil carry over rate of less than one per cent improves heat transfer properties and increases system efficiency and reliability.
