Features
Single-stage, air-cooled, compressor for compressing purified gas.
Note: permissible H2S content up to 4,000 ppm depending on application.
The rotary vane gas compressor complies with Directive 94/9/EEC.
Suitable for transporting explosive gases and vapors in explosion group IIB, temperature class T2 in zone 1. It can be operated in zone 1.
ATEX
II inside 2G c IIB T2
II outside 2G c IIB T2
Design
- Compact unit
- All components are mounted on a main frame
- Rubber-metal elements to reduce vibrations
- Electrical control panel wired to terminal boxes
- Installation does not require foundation.
Compressor stage
- Rotary vane compressor stage
- Fresh oil injection cooling
- Multi-cell design principle, driven directly via an elastic coupling between the drive motor and the compressor stage
- Suitable for compressing purified gas
- Outstanding operating reliability
- Dynamic oil film between vanes and the inner wall of the compressor housing
- Low rpm and self-centering rotor
Gas Path
The gas flows through the suction line to the compressor stage. Here it is compressed as a result of the increasingly smaller volumes of the compression chambers. The compressed gas exits from a compression fitting on the compression stage through a check valve and enters the compression-side piping system.
Cooling
The compressor is cooled by a direct-drive cooling air blower on the A side of the compression stage. The heat of compression is transferred to the incoming cooling air via the cooling ribs on the exterior of the compressor housing. The L 50-100 sized compressors have an additional cooling air blower on the A side of the compressor stage.
Drive
The compressor stage is driven directly via an elastic coupling with coupling protection between the drive motor and the compressor stage shaft.
Safety Equipment and Display
- Temperature switches to monitor the gas outlet temperature
- Level monitor to check the oil level in the lubricating oil tank
- Pressure gauge for compressor pressure
- Check valve on the pressure side
Service
Service and maintenance are costly and time consuming necessities. To keep your costs down we offer hands-on workshops for your technicians to empower them to carry out service fast and efficiently at your plant. Successful attendance of our in-depth trainings for ATEX machines is rewarded with a certificate. If your machine actually breaks down we provide fast and efficient support from the factory.
