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 2014/34/EU
- 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 with acoustic hood and cooling air blower.
- All components are mounted on a main frame
- Rubber-metal bonded elements to reduce vibrations
- Electrical control panel wired to terminal boxes
- Can be installed without the need to provide a foundation
Compressor Stage
Rotary vane compressor stage with
- Fresh oil injection cooling
- Multi-cell design principle
- Direct drive via elastic coupling between the drive motor and the compressor stage
- Suitable for compressing purified gas
- Outstanding operating reliability
- Dynamic oil film between the rotor 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 separate cooling air blower in the acoustic hood. The intake cooling air flows through the acoustic hood from the bottom to the top and is discharged to the outside through the discharge air hood.
Drive
The compressor is driven by a built-in electrical motor via V-belt.
Safety Equipment and Display
- Check valve on the pressure side
- Contact pressure gauge to monitor the compressor pressure, with two electric switching contacts, measuring range: 0 to 4.0 bar
- Contact thermometer to monitor the outlet temperature, with two switching contacts, measuring range: 0 to 300 °C
- Emergency stop switch to shut off the compressor in emergency situations
- Terminal box (Exe/Exi) for wiring of electrical components
Service Offer
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.
