Hydraulically Driven, Dry-Running Piston Compressors
Hydraulically driven, dry-running NEA|HOFER TKH piston compressors have a particularly simple design. They compress lubricant-free, non-corrosive gases such as hydrogen, helium, argon, nitrogen, carbon dioxide and ethylene. The maximum discharge pressure is 4,200 bar. NEA|HOFER TKH are characterized by their ease of maintenance: Depending on the compressor size, a piston seal can be replaced in 10 to 30 minutes.
If the compressor is used in an ex-zone, the hydraulic unit is usually installed outside the zone. The pressure oil connection is made through a gas-tight wall.
We can also provide explosion-proof hydraulic units on special request. The NEA|HOFER TKH is characterized by its small space requirement. As the stages can be easily arranged above one another, it is ideal for installation in containers.
