The hermetic compact screws complete the compressor screw programme in the lower capacity spectrum. They are suited for insertion into factory finished air conditioning units, liquid chiller units and in particular also for the air conditioning of railway carriages.
The space saving design with integrated oil separator and reservoir enables the simplest installation. With their small height, low weight and very smooth running over a wide speed range, they already meet today the increasing demands of confined roof and under floor installations.
The deciding features:
Approval according to the EC Pressure Equipment Directive 97/23/EC Maximum allowable pressure 25 bar.
For the series VSK41 a new form of regulating system has been developed (accessory). The basic principle corresponds to that of a control slide of industrial compressors. Thereby the displacement is reduced by moving the suction side sealing controur. The control unit is so designed that it does not reduce the stability of the compressor housing. The gaps between the rotors and the housing thus remain within tight tolerances, even with high temperatures. This measure is an important stage of development for a good overall efficiency of smaller screw compressors, due to the higher demands on precision.
BITZER's new SPEEDLITE ELV52 is the ideal total package for mobile air conditioning and heat pump systems.
Due to their horizontal and space-saving design, the BITZER hermetic scroll compressors are suitable for compact train A/C units.
BITZER's CO₂LITE compressor ideally suits HVAC units in the rail sector with low height requirements, such as metro applications.
The new SPEEDLITE ELV52 scroll compressor from BITZER is optimally designed for railway-specific requirements.
