Are you aware of DV Systems Heater Kit (DSC-002734) for rotary screw air compressors?
This heater kit is typically used in special cases where either:
the air compressor is located outdoors in a location where the temperature dips below 5ºC/41ºF at night, but returns to warmer temperatures during the day, or the air compressor is located in a 'cold room', or space where the temperature dips below 5ºC/41ºF or is unregulated.
Why is a Heater Kit necessary in these situations? The controller on DV Systems rotary screw air compressors prevents the unit from starting during extreme ambient conditions when the oil temperature sensor indicates that the lubricant is below 5ºC/41ºF.
The heater kit (DSC-0012734) ensures the temperature of the lubricant in the rotary screw air compressor is maintained above the temperature inhibit limit of the air compressor controller.
