Our designers at Calco Electric create premium thermostats that are accurate and efficient. Each of our thermostats has a specific design to meet your specific needs, whether you own a home or an industrial business.

Temperature Regulation

Thermostats are components that measure temperature in a given space. The system is preset for a specific temperature, called a setpoint, and the thermostats turn the heat on or off to meet the exact or approximate temperature. Thermostats may also stop or start a heat transfer fluid, which would also regulate the temperature.

Any equipment, system, or device that cools or heats at a setpoint need thermostats. These include HVAC systems, central heating, heating, air conditioning, scientific incubators, medical equipment, refrigerators, ovens, and more.

Thermostats are built many different ways. Typically, thermostats contain a bimetallic strip or a thermistor to measure and regulate the temperature. Using an output sensor, the thermostat then manages the cooling or heating.

Most thermostats operate either the heating or cooling element until the sensor detects that it has met the set temperature. Then the thermostat turns off the electricity until it detects that it needs to turn on to meet the set temperature again.

Narrow Differential Thermostats

Our teams at Calco Electric provides customers with high-quality Narrow Differential Thermostats. These thermostats are typically used in industries that need accurate heat treating ovens.

Extreme Precision from Calco Electric

Because these thermostats are integral to industries, they must be especially precise. To do this, the narrow differential thermostat must turn on and off at closer tolerances. This means that its differential is more narrow, making the heat turn on and off more rapidly.

Narrow Differential Thermostats use snap action with bimetal discs to open and close the contact. Bimetal discs are made of two different kinds of metal, with one loosening faster than the other. This places tension inside the thermostat, disconnecting the contact that keeps the heat turned on.

The bimetal thermal switch is a 17AME-H. Its lowest temperature is from 0°C to 180°C. It is particularly designed to handle lighting, heating, and motors. Engineers made the switch to concentrate on small temperature differential (called the narrow differential) and the low-temperature range.

With the bimetal heat expanding and the cold contracting, the thermal switch is able to turn on and off. This allows the element to control the area’s temperature within a small range of heat.

The narrow differential thermostats from Calco Electric include:

  • 100% regulated temperature
  • Snap action as well as creep action
  • Personalized wire length and type
  • 100% RoHS Compliant
  • 100,000 life cycles for long-term capacity
  • Personalized terminals located at the same or opposite ends

Creep Action Thermostats

At Calco Electric, we give our customers the top quality and service for thermal cutoffs, thermostats, thermal protectors, thermistors, insulated heater wires, thermal cutouts, and more. One of our products is a Creep Action Thermostat, which has the best accuracy in staying at the setpoint

Precision & Accuracy

Thermostats contain two dissimilar metals that are bound together. As the thermostat regulates the temperature, one of the metals will expand faster than the other metal, creating a rounded arc. As the arc increases, the contact between the metals is lost, turning the thermostat on and off to adjust the temperature.

Regular thermostats have a range of accuracy that can vary between 1 or 2 degrees of the setpoint. Creep Thermostats are more precise, using a coil form of the metals to remove the range and meet the setpoint.

Sustained Response

Creep Action Thermostats guarantee you a sustained response. It has a slow cutout set at your specific trip point. Its low make and slow break action are triggered precisely around the setpoint.

Our line includes a wide variety for any need you may have:

  • JRMC, JRMD, and JRMD-E Creep Action Thermostats use a bimetal slow break and slow make mechanism to regulate temperatures and limit thermal activity. These are also available in gold diffused contacts.
  • WAA2 Creep Action Thermostats are specially designed to provide temperature control for different appliances. These are typically found in medical cushions, car seats, and heating pads.

Bimetal Thermostats

Bimetal Thermostats, which regulate the temperature inside heating pads, blankets, and medical pads, are used in any case where the applications need control for a low temperature.

Bimetal Thermostats use two different kinds of metal to regulate the temperature setting. When one of the metals expands more quickly than the other, it creates a round arc, like a rainbow. As the temperature changes, the metals continue to react differently, operating the thermostat. This opens or closes the contact opener, turning the electricity on or off as needed. Accuracy and efficiency are important for bimetal thermostats.

At Calco Electric, we have a variety of bimetal thermostats for your selection:

  • ½” Snap Action Bimetal Disc Thermostat: HB-2 is compact, reliable, and cost-efficient. It is also compact with its ½” design.
  • ¾” Snap Action Bimetal Disc Thermostat: HB-7 uses snap action to create high-speed contact separation, giving you a versatile, cost-efficient method of regulating temperatures.
  • AMT-P1 Series Bimetal Thermostat provides more reliable, safe protection for your circuits. It uses an open frame design for efficiency.
  • High Temperature Bimetal Thermostat: H702 can control temperatures reaching 400°C; typical disc thermostats can’t handle temperatures over 230°C because of a refractory issue.
  • JUC 31F Series TO-220 PCB-Bimetal Disc Thermostat meets RoHs standards. As a snap action SPST bimetallic thermostat, it gives accurate regulation for one device. We are the only company that provides low-temperature regulation reaching 0C (32F).

Thermostats are used to monitor and maintain temperatures within an expected range of heat or cold. Thermostats are used in countless everyday applications, as all devices that heat or cool to a certain temperature use thermostats. Some common items include:

  • Home temperature thermostats
  • Refrigerators
  • Medical equipment
  • Ovens
  • HVAC systems
  • Electric hot pots or clothes irons

Resist Water Damage

Waterproof thermostats complete the same function while also resisting water damage. These types of thermostats are highly beneficial for use in designs where moisture may be present, such as refrigerators or other appliances.

All thermostats use a “closed loop” control device to guarantee the accuracy of temperature. These components unite sensing and controlling elements within a controlled action system to make certain the temperature is maintained.

Thermostats include a bimetallic strip or sometimes a thermistor to manage the temperature’s range in a given area. Once the temperature reaches a setpoint, the thermostat will shut off the electricity until it senses that the temperature needs adjusted again.

At Calco Electric, designers created the KSD301-M Watertight/Waterproof Thermostat to be waterproof. Its main body protection class measures at IP57, sealing out moisture so that it can be used in liquid applications.
