Scroll compressor ESH Tandem - 2 x ESH730(B)Y

BITZER offers kits for tandem units for parallel operations. They consist of two compressors connected in parallel and provide significant benefits over individual compressors with the same output. The compound compressor units are distinguished by groundbreaking technical features, extraordinarily high energy efficiency and reliability.

Efficient capacity control through pairs of compressors with equal and unequal displacements
Optimised pressure and suction pipe arrangement in combined compressor unit
Reliable oil and gas equalisation
Solid frame construction for low vibration levels
Compressor with Rotalock or direct brazing connections
Suitable for the refrigerants R134a, R407C, R404A, R507A and R22
