Just as we winterize our cars or winterize our homes; we can winterize our compressed air system.
Drain all excess water from system - Open drain valves on air receiver tanks and let excess water escape.
Make sure all drains (automatic or manual) are working properly.
Monitor ambient temperature in the compressor room. We suggest adding an inexpensive thermostat to the area that is visible from the door of the compressor room.
If compressor room is not heated from plant heat/air, we suggest adding a small portable electric heater to the room that is thermostatically controlled. This will help to maintain ambient temperature above freezing. As with all portable heaters; use necessary precautions. Keep all flammable material away from heater.
Close any windows, doors or louvers that are a source of cold air. We suggest installing thermostatically controlled louvers in the compressor room.
Make sure that the coolers and cooling coils are clean and free of dirt and dust.
Make sure the oil levels are at the appropriate levels.
If your compressed air system in housed outside or in a shed: Heat tapes or cold weather packages may help.
We recommend that the compressed air system be in a room that can be heated during the winter and have proper ventilation in the summer.
