Cold weather and air compressors aren’t best friends. When the temperature drops, the oil in your system becomes more viscous and the condensate within the system can freeze. Both can be bad news for your compressed air system.
• Viscous oil or coolant can prevent the air compressor from switching on or cause it to trip
• Condensate (that is, condensed water and oil) will collect at the lowest parts of the system and freeze, blocking airways, filters and dryers, potentially placing too much stress on the compressor, and damaging other downstream components
A frozen air compressor, therefore, can damage multiple components and bring production to a halt – but here’s how you can avoid the cost of a callout:
• Drain all air receivers, condensate drains and electronic drain valves of water. The less condensate in the system, the less chance it will freeze, and the less damage it will cause if it does
• If possible: insulate any oil/water separators that are exposed to the elements
• Cover all rotary screw air compressors or install small cabinet heaters within them to prevent the ambient temperature dropping below freezing. If you need advice on this, just call us
• Service regularly: servicing delivers lots of benefits, but one of the less obvious ones is that it prevents a build up of water within the lubricating oil. Too much water within the oil and it will freeze
