Ambient temperature
* Environmental temperature range for use : –25℃～55℃.
* For use in minus temperature, in-fit space heater is available at option.
* For use in temperature beyond the specified range, refer to our Sales Dept.
Fluid temperature
It is occasional that if the actuator is applied to a high temperature fluid line, the unit may
overheat by transmission of line heat. In such a case, use radiation type bracket and couplings.
(available at option)
* Standard bracket and couplings : Fluid temperature max. 65℃
* Radiation type bracket and couplings : Fluid temperature over 65℃
