How it works

The air end is driven by an electric motor. The fluid injected primarily for cooling purposes during the compression process is re-separated from the air in the fluid separator. The integrated fan ensures cooling of the compressor package and also provides sufficient flow of cooling air through the oil cooler and compressed air aftercooler.
The controller ensures that the compressor produces compressed air within the set pressure limits. Safety functions protect the compressor against failure of key systems via automatic shutdown capability.

  • The world-renowned German GHH mainframe is characterized by remarkable efficiency and stability.
  • The classic Siemens motor is suitable for constant speed or variable frequency speed control applications of Kotech air compressor.
  • Siemens man-machined control panel, let Kotech air compressor simple operation, farewell cumbersome.
  • VMC intake valve ensures stable intake adjustment and loading and unloading of the Kotech air compressor.

 

2. Intellectual

KOTECH air compressor preferred Siemens CPU controls the operating status of the air compressor in real time.

 

3. Reliable

Hot and cold partition design ensures the best operation of each component.
2.1.Independently inhaled and inhaled natural gas at normal temperature;
2.2.Ensure the drive motor has good heat dissipation;
2.3.Independent electric cabinet ensures good heat dissipation and service life;
2.4.The machinery and electrical appliances are completely isolated, more safer and stable;
2.5.The compressor can be operated at an ambient temperature of up to 46 ℃.

 

4. Energy Saving

Minimal operating costs – exceptional productivity
High efficiency in partial-load operation
Significantly greater efficiency- especially in the partialload range – than comparable asynchronous systems helps achieve considerable energy savings.The ultra-high stability of Siemens motors increases the productivity of machines and systems.
For example, Siemens motors maintain a constant efficiency over a partial load range,This allows savings of up to 8 % conpared with conventional variable-speedsystems.

 

5. Environmental Protection

Process , heating and service water
Hot water , up to70 ℃, can be produced from reusable compressor heat via heat exchanger systems. Please contact Fu promise air regarding higher temperature requirement.

Clean Hot Water
If no other water circuit is interconnected, special fail-safe heat exchangers meet the highest demands for the purity of the water being warmed, as is the case with cleaning water in the food industry for example.

How it works

The air end is driven by an electric motor. The fluid injected primarily for cooling purposes during the compression process is re-separated from the air in the fluid separator. The integrated fan ensures cooling of the compressor package and also provides sufficient flow of cooling air through the oil cooler and compressed air aftercooler.
The controller ensures that the compressor produces compressed air within the set pressure limits. Safety functions protect the compressor against failure of key systems via automatic shutdown capability.
