Scroll Compressors ESH - ESH736-Y

Bitzer scroll compressor ESH - ESH736-Y

Scroll compressor ESH - ESH736-Y

With the extended ES series, BITZER has innovative scroll technology for applications in air conditioning systems and heat pumps. The compressors are distinguished by groundbreaking technical features and extraordinarily high energy efficiency. The range includes models with a rated motor power ranging from 7.5 to 15 PS for the refrigerants R134a, R407C, R404A, R507A 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 BSE35K required.)
