Oil-Injected Rotary Screw Compressor Dryer Maintenance

Check mark

Safety Precautions

Check mark

Refrigeration dryers of ID type contain refrigerant HFC. When handling refrigerant, all applicable safety precautions must be observed.

Check mark

Contact of refrigerant with the skin will cause freezing. Special gloves must be worn. If contacted with the skin, the skin should be rinsed with water. On no account may clothing be removed.

Check mark

Fluid refrigerant will also cause freezing of the eyes; always wear safety glasses.

Check mark

Refrigerant is harmful. Do not inhale refrigerant vapours. Check that the working area is adequately ventilated.

Check mark

Be aware that certain components such as the refrigerant compressor and the discharge pipe can become quite hot (up to 110 °C - 230 °F). Therefore, wait until the dryer has cooled down before removing the panels.

Check mark

Before starting any maintenance or repair work, switch off the voltage and close the air inlet and outlet valves.

4000 Hourly Oil and Oil Filter Replacement

Check mark

WARNING! The operator must apply all relevant Safety precautions

Check mark

Always drain the compressor oil at all drain points. Used oil left in the compressor can contaminate the oil system and can shorten the lifetime of the new oil

Check mark

Never mix lubricants of different brands or types as they may not be compatible and the oil mix will have inferior properties. A label, indicating the type of oil filled ex-factory, is stuck on the air receiver/oil tank

Check mark

Run the compressor until warm. Stop the compressor after 3 minutes of unloaded operation. Close the air outlet valve and switch off the voltage. Wait a few minutes and depressurise by unscrewing oil filler plug (FC) just one turn to permit any pressure in the system to escape

Check mark

Air cooled units: loosen the vent plug (VP) of the oil cooler and wait for 5 minutes

Check mark

Remove drain plug (DP1) and open drain valve (Dm)

Check mark

Also drain the oil by removing the drain plug: on the check valve and on the gear casing

Check mark

Collect the oil in a collector and deliver it to the local collection service. Refit and tighten the drain and vent plugs after draining

Check mark

Close the drain valve (Dm)
