IMI Heimeier
​​​​​​​ Thermal actuator for heating, ventilation, and air conditioning systems The EMOtec thermal actuator with position indicator (NC) can be installed in temperature and/or timerelated 2-point control systems.

Compact sizes especially suited to manifold cabinets

Simple functional testing by means of position indicator (with NC model)

Safe because of overvoltage protection (with 230 V model)

Trouble-free because it is silent and needs no maintenance
