Scroll Compressors ELH - ELH725(B)Y

Bitzer scroll compressor ELH - ELH725(B)Y

Scroll compressor ELH - ELH725(B)Y

With the ELH series, BITZER has a horizontally oriented scroll compressor series for use in transport air conditioning. Thanks to their horizontal and compact designs, the compressors are best suited to compact air conditioning units in rail- and electric bus applications. The range includes models with a rated motor power ranging from 7.5 to 15 hp for the refrigerants R134a, R407C and R22.

  • High output and efficiency bacause of optimised spiral geometry, high motor efficiency and precise manufacturing
  • Controlled contact pressure on both spirals – radial and axial
  • Optimal jointing between the compression chambers
  • Robustness during liquid slugging or if debris is sucked in

With R134a (Polyolester oil BSE55 required.)
