TEMPERATURE AND PRESSURE SWITCHES

 

 

TEMPERATURE SWITCHES

DYNO-TRON THERMO-FAN sensors and relays will control the operation of a fan system by monitoring the temperature of water, oil or air. Available for 12- and 24-volt applications, the normally open bi metal snap action switches will close on temperature rise sending a signal to a relay to start or stop a fan system. For accurate fan control and optimum performance, sensors should be installed in the return line of the cooling system. Other locations are not recommended. Sensors must be used with a relay. When ordering, specify 12- or 24-volt.

PRESSURE SWITCHES

DYNO-TRON on/off pressure switches and relays will continue the operation of a fan by monitoring high head pressure in an air conditioning system. When the AC pressure rises, the normally open switch closes, sending a signal to start a fan system. Sensors must be used with a relay and be installed by a qualified person familiar with air conditioning systems. When ordering, specify 12- or 24-volt.
