Quality assurance – bench test of every air end
Highest flexibility for your package design - Suitable for all types of driving motors
- Drive options: Belt drive, direct drive, internal gear drive
- Base and face-flange mounting
Electric motor Only electric motors from well-known manufacturers of protection class IP55, TEFC, SF1.2, IE3/IE4 are used. As a standard, the drive motors are monitored both thermally (via the thermistor of the motor) as well as electronically (overload protection via the frequency inverter).
Oil separation system Compressors up to 132 kW are equipped with external separators that can be changed in a simple spin-off/spin-on process. Larger units have an internal separator cartridge. Due to the excellent separation efficiency of the system as a whole, the compressors can be used in the pressure range of 5.0 to 15.0bar. Special pressures available upon request.
Oil circuit
- The design of the oil circuit can effectively enhance the sealing performance so as to extend the interval between lubricant changes. An oil level sensor is integrated to effectively sense the oil level. It is visual and can alert users to maintain the machine.
- All the units in this series have a horizontal oil separation vessel in which the oil is separated from the compressed air highly efficiently at low speeds.
High durability& performance intake valve system
- We use high end AIV/JIV/MPV series intake valves
- Safe: 16bar design pressure
- Reliable: higher quality
- Longer life: reliable spare parts
High efficient& enlarged cooling system, centrifugal fan (optional)
- Motor IP class: IP44;
- Motor with self-cooled function;
- Motor with high efficient service factor;
- Low cooling air flow;
- Lower cooling air pressure;
The SMART CONTROLLER ensures efficient control and system monitoring The controller can work in block mode with multiple compressors. Up to 16 machines can be remotely connected.
Frequency inverters (optional) The frequency converter minimizes idle times and optimizes supply with fluctuating compressed air.. Start-up peaks are avoided and the compressor’s delivery rate is controlled continuously–that saves electricity costs! The total costs for your compressed air supply are significantly reduced and investment costs are amortized in the shortest possible time.
Designed to meet your needs Our LGCD series direct drive rotary screw compressor can be designed and configured according to your specific needs, such as air-cooling / water-cooling method, oil content, weight and dimension.
