Page 7: Description
2 Description The CN20033 - CN20090 range of nitrogen generators operate on the Pressure Swing Adsorption (PSA) principle to produce a continuous stream of nitrogen gas from clean dry compressed air. Dual chamber columns, filled with extruded beads of adsorbent (Carbon Molecular Sieve [CMS]) material, are joined via an upper and lower manifold to produce a two bed system. -

Page 11: Locating The Equipment
2.4 Locating the Equipment 2.4.1 Environment The equipment should be located indoors in an environment that protects it from direct sunlight, moisture, and dust. Changes in temperature, humidity, and airborne pollution will affect the environment in which the equipment is operating and may impair the safety and operation. It is the customers' responsibility to ensure that the environmental conditions specified for the equipment are maintained. -
Page 12: Installation And Commissioning
3 Installation and Commissioning Only competent personnel trained, qualified, and approved by Compair should perform installation, commissioning, service and repair procedures. 3.1 Recommended System Layout Description Description Description Description Compressor Dryer pre-filtration Generator Dust filter Wet air receiver Pre-treatment dryer... -
Page 13: Mechanical Installation
3.2 Mechanical Installation Fit one of the 1/2Ý ball valves supplied to the compressed air inlet port on the generator and attach the compressed air supply to this ball valve. Ensure that the valve is in the closed position. Fit another of the 1/2Ý ball valves supplied to the port marked “To Buffer vessel”. Install 1/2” NB / 16mm ID piping between the ball valve and the buffer vessel inlet port. -
Page 14: Electrical Installation
3.3 Electrical Installation A fully qualified electrical engineer must undertake all field wiring and electrical work in accordance with local regulations. In order to maintain the IP rating of the generator, all cables entering the electrical enclosure must do so through the dedicated cable glands located on the side of the generator. -
Page 15: Generator Supply
3.3.2 Dryer Supply If a Compair pre-treatment air dryer is used, it should be connected to the generator at the dedicated DIN rail terminals. Refer to the documentation provided with your dryer for additional information on installation requirements. -
Page 16: Operating The Generator
4 Operating the Generator 4.1 Overview of controls There are two control options available for this range of generators: A–Control with O Analyser. When fitted with an O analyser the controller provides a visual indication of the operating status of the generator. In addition to this the menu driven interface provides access to essential information such as oxygen purity, hour meters and fault logs. -
Page 17: Starting The Generator
4.2 Starting the generator Make sure that all connection points are secure and all of the ball valves on the system are closed. Open the ball valve (BV1) on the compressed air inlet port. Switch ‘ON’ the electrical power to the generator and wait for the controller to complete the initialisation routine. -
Page 18: Start Clean Up
The Start clean up cycle can be disabled within the customer settings menu (applies only to generators fitted with an O analyser), however Compair strongly recommend that the start up cycles remain enabled. 4.5 Economy Mode Economy mode is designed to switch the generator into standby mode when there is no demand for gas. -
Page 19: Menu Interface
4.6 Menu Interface The default menu displays the current operating status of the generator and, when running, indicates the purity of the gas delivered at the “Nitrogen Outlet” port. Note. The purity reading is for indication purposes only. The menu driven interface provides access to the essential operational parameters of the generator. From the default menu use the keys to scroll through to the desired menu and press The interface will automatically default back to the main operating menu if no key activity has been detected for one minute. -
