Advantages
1. Low Temperature, High Efficiency
With an exceptionally low running temperature of less than 60ºC, near isothermal compression is achieved. The superior cooling capability of water removes the heat and gives more air per kW of power. This also eliminates the need for an internal cooler and aftercooler, reducing power consumption and pressure drop to a minimum.
2. Cutting Maintenance Costs
Spare parts only require air filter elements and water filter elements. Low operating temperature ensures the long service life of the screw air end, avoiding expensive maintenance costs for the screw rotor and reducing stress on other components.
3. Avoid Extra Energy Costs
Combat pressure drop costs efficiently. These hidden costs, though not apparent at the time of purchase, are very high and contribute substantially to the total cost of ownership.
4. No Gearbox
Features a configuration with no gearbox, completely eliminating the need for associated oil lubrication.
5. Simple Structure
Fewer moving parts than the dry oil-free screw air compressor, meaning there is less to go wrong, while balance bearing loads extend the compression element service life for low-cost operation.

Frequently Asked Questions
What are the benefits of the low operating temperature of the compressor?
▼
With a running temperature of less than 60ºC, near isothermal compression is achieved. The superior cooling capability of water removes heat, providing more air per kW of power. It also eliminates the need for internal/after coolers, minimizing pressure drop.
How does this system cut down maintenance costs?
▼
Maintenance is simplified as the system only requires replacement of air and water filter elements. The low operating temperature ensures a long service life for the screw air end, preventing expensive maintenance on the screw rotor and other components.
Does the compressor system feature a gearbox?
▼
No, the system is designed with no gearbox, which completely eliminates the need for associated oil lubrication, simplifying the operation and saving costs.
What configuration voltages are supported for the scroll machines?
▼
Supported voltages include 380V 3PH 50HZ, 380V-3PH-60HZ, 460V-3PH-60HZ, 220V-3PH-60HZ, 400V-3PH-50HZ, 6000V-3PH-50HZ, and other customized voltage options.
Why does a simpler compressor structure lead to lower-cost operation?
▼
Having fewer moving parts than dry oil-free screw air compressors means there is less to go wrong. Balanced bearing loads also extend the compression element's overall service life.
