Ambistat for the control of ventilation flaps in elevator shafts
The room thermostat ASE40 from Swiss-based Trafag AG is used for the regulation of ventilation flaps in elevator shafts. Between 25°C and 35°C the thermostat switches the ventilation flaps with an accuracy of 0.15°C. The switching differential delta T for this usage is fixed by Trafag to 10°C. The flap opens at 35°C and closes again at 25°C. The thermostat can thus be adjusted according to the wishes of the customer.
The thermostats made by Trafag have a closed capillary system. The repeating accuracy of the temperature regulator is 0.5% of the temperature range. The mechanical temperature regulator or -limitator does not need an electrical supply. It is maintenance-free over decades with the same constant high accuracy.
