Anti-condensation heater

A space heater can increase the internal temperature and keep dry inside the actuator to avoid the freezing lubricant and moisture causing actuator failure under low temperature or high humidity. Heater is not recommended if the ambient temperature is higher than 35℃ (95℉). However, when the temperature varies much from day to night or between summer and winter, heater and thermostat are recommended.
