Bitzer 4VES-7Y-40P Ecoline Semi-Hermetic Reciprocating Compressor - R134A

Description

Bitzer 4VES-7Y-40P Ecoline Semi-Hermetic Reciprocating Compressor - R134A
The ECOLINE series has now been extended to all models and the optimisation package has been developed further for universal use with different refrigerants – at the same time extending the operating ranges.
The refrigerants include: R134a, R404A, R407A, R407C, R407F, R507A, R22, R290 and R1270.
The compressors are already designed for operation with "Low-GWP" HFO refrigerants and HFO-/HFC blends.
BITZER Ecoline  -  Model: 4VES-7Y-40P
The coefficient of performance (COP) of the new ECOLINE models has been improved by an average of 6% up to a maximum of 12% compared with preceding series. This is not achieved with a single component, but by optimizing the valve plates, reducing flow losses and discharge gas pulsation as well as specially adapted highly efficient motors with broad band characteristics. Each ECOLINE is compatible with its predecessor compressor.  These predecessor compressors can be substituted without the need for modifying the system.   Whereas many of the major internal components have been redesigned, the outer shape has remained virtually unchanged: the same outer dimensions, unchanged mounting points, valve and sensor positions, connections for oil and gas equalization, as well as for oil level regulators.
Motor version 2 covers the classic refrigeration applications – medium and low temperature refrigeration – with one single product. In many cases it can thus replace a predecessor compressor with motor version 1.
For supermarket applications with R134a, a version with specially adapted motor is available for the ECOLINE models CE4, BE5 and BE6 – motor version 3 – in addition to motor version 2.
Motor version 3 has been specially designed for the pressure levels of R134a and focuses on applications in the medium temperature refrigeration range in modern systems.
For compressors with motor version 3, the standard motor can be operated with a frequency inverter up to 70 Hz (for mains voltage 400V/3/50Hz)
