Compressor description by Ralkin

Bitzer ECOLINE H Series 6HEH-35

The Bitzer ECOLINE H series represents a creative advancement of the robust and powerful semi-hermetic ECOLINE range, designed for high efficiency, smooth running, and high reliability. Specifically engineered for demanding conditions, this series features a reinforced drive gear and lubrication system, making it the ideal specialist for high-temperature heat pumps (using refrigerants like R1234ze(E), R515B, and R245fa) and transport applications such as railway air conditioning.

Model Identification

  • 6: Number of cylinders (6-cylinder configuration).
  • H: Special design for transport applications and high-temperature heat pumps, equipped with an additionally reinforced drive gear and lubrication system.
  • EH: Identification for bore x stroke (Series specific bore/stroke dimension).
  • 35: Motor size identifier.

Technical Features

  • Specialized Design: Reinforced drive gear and lubrication system tailored for high-temperature heat pumps and transport refrigeration.
  • New Valve Plate Design: A new geometric concept for pressure valves ensures low rear expansion, providing high cooling capacity with minimal energy requirements.
  • Efficient Motor: Broadband motor characteristics ensure high efficiency under both full- and part-load conditions.
  • Capacity Control: The CRII system allows for intermittent blocked suction, offering a control range from 100% down to approximately 10% (on 4-cylinder models).
  • Downward Compatibility: The series is designed to replace predecessors with the same connection sizes.

Specifications & Data

Based on the Bitzer ECOLINE H series data tables:

  • Displacement: 110.5 m³/h (at 50 Hz).
  • Heating Capacity (Qh): 92.50 kW (Rated condition: R515B at evaporating temperature 30°C / condensing temperature 85°C).
  • Oil Charge: 4.75 dm³ (Typically Polyolester oil BSE85K for high-temperature applications).
  • Weight: 241 kg.
  • Electrical Data (Part-Winding Motor): Max. operating current is 64.4 A.
  • Primary Refrigerants: R1234ze(E), R515B, R245fa.
