DH series water lubricated rotary screw compressor
DH
The DH series contains absolutely no oil, no matter where the compressor is used, and is ISO 8573-1 Class Zero (2010) and silicon-free certified.
The unique design allows for lower speeds and cooler operating temperatures - both contributing to increased efficiency and reduced component wear. A single-stage direct drive motor with no gears or belts maximizes efficiency. Using variable speed technology to limit compressed air to application demands ensures that no energy consumption is wasted.
• Single-stage direct-drive compressor element maximizes efficiency and reduces maintenance
• Premium water spray lubricates, cools and seals the compression process for maximum efficiency
• No gearbox means no need for associated oil lubrication
• Lower bearing loads and speeds mean permanently sealed bearings can be used without oil lubrication
• Variable speed technology available to reduce energy costs
• Comprehensive control functions ensure safe and reliable operation, including remote communication capabilities
• Fully sealed and sound-dampening enclosure reduces noise and simplifies installation
• Unique design allows for lower speeds and cooler operating temperatures - both for increased efficiency and reduced component wear. A single-stage direct drive motor with no gears or belts maximizes efficiency. Using variable speed technology to limit compressed air to application demands ensures that no energy consumption is wasted.
• Compared to similar equipment, DH compressors have significantly fewer moving parts, which reduces the chance of failure, while lowering operating speeds, balanced bearing loads, and longer compression element life, resulting in lower operating costs.
• Can achieve ultra-low operating temperatures below 60°C with near isothermal compression. This also eliminates the use of an internal secondary cooler and associated energy consumption, reducing pressure drop to an even lower level.
• Balances compressive loads, reducing bearing loads for greater reliability:
• Tested reverse osmosis filtration provides high quality purified water to lubricate, seal and cool compression processes. Using an osmotic pump, the required water volume can be reduced to even lower levels.
