EXPO THERMOCONTROLS PVT. LTD. Delhi

The Simmerstat provides infinitely variable control of the heat output of electric hotplates, boiling rings, grills, Grill – boilers, warming cupboards etc. Its smooth action allows any heat from zero to full to be selected at the turn of a simple control. The simmerstat cuts down electricity consumption by up to 50 percentage. No special allowance for fitting are necessary as it occupies the same space and utilizes the same fixing holes as ordinary three-heat switch and wiring is simplified.

Expo hydraulic thermostats have proved effective as regulating and controlling units in heat convectors, electric ranges, washing machines, OTG, room heaters, storage heaters, heating appliances, deep fryers, water baths, oil baths etc. These thermostat s are intended to regulate the temperature of liquids, gases and solids. Manufacturing of these thermostats requires the finest workmanship.

It is a snap action thermostat in which the contacts open instantaneously as soon as the fixed temperature is reached. Any temp. upto 280°C can be set in the factory as per customer’s requirement. It is mostly used in toasters, iron, incubators, sterilizers, surgical & industrial equipment’s, hot plates, etc.  

The  Expo switches are of high quality and are used in hot plates, coolers, washing machines, electric cooking ranges etc. Rotary Switches are to 5 Amps and 15Amps rating and are fitted with very fine quality contracts for long lasting. The contacts close or open as per the diagram shown. The switches consist of Bakelite body except for the hot plate switch. The hot plate switch has a ceramic base to withstand high temperature. The switches have a 360° rotation. The switches are provided with a black or white knob with proper marking. Single hole fixing is provided by a threaded brush. The switch is secured by a single center  fixing nut. The connections should be made as per the diagram shown.

Expo stem type thermostats are very accurate thermostats. These are specially designed for controlling the temperature of geysers, oil and water baths, sterilizers, air ducts, etc. STEM TYPE GEYSER TH. 7" STEM TYPE GEYSER TH. 11" STEM TYPE GEYSER RESET 7" STEM TYPE GEYSER RESET 11" Other sizes as according to our customer need. Stem type therostat operates by opening and closing a snap-action switch in the load circuit. It consists of a brass tubing which is the sensor for operating and as soon as the particular temperature is reached the switch opens and thus switched off the mains supply to the load. When the temperature at the brass tube fall below a certain level the switch makes the contact and the mains supply to the element is restored. In this way the temperature can be set by adjusting the screw.
