Page 6: Operating Principle
Conveying of other media leads to an increased thermal and/or mechanical load on the machine and is permissible only after a consultation with Busch. The machine is intended for the placement in a non-potentially explosive environment. The machine is capable of maintaining ultimate pressure, see Technical Data [➔ 40]. -
Page 7: Standard Features
Product Description | 2 Standard Features 2.4.1 Air Cooling The machine is cooled by a cooling liquid circuit in the cylinder cover and cylinder. The cooling liquid pump (CLP) allows a recirculating flow in the cooling liquid chamber. The cooling liquid is cooled by an air-water heat exchanger (AHE). A motor driven fan, integrated to the heat exchanger, allows the cooling air to be drawn through the heat exchanger. -
Page 8: Nitrogen Panel
2 | Product Description 2.5.6 Nitrogen Panel The nitrogen panel fitted to the base frame allows the supply of nitrogen to a number of different points on the machine. Each device consists of a solenoid valve to open or close the gas circuit, a pressure regulator and a flow meter to adjust pressure and volume flow separately. -
