Oil heater /OH

An oil heater is required to ensure lubrication during a cold gear unit startup when the ambient temperature is low.

The heater is screwed into the gear unit housing at the factory and is controlled by a thermostat. Depending on the lubricant used, the temperature limit below which the oil must be heated is set at the factory.

When performing a cold gear unit startup, also observe the oil viscosity outside of the gear unit, e.g. in the oil pipes.
