Also known as snap discs, these thermostats switch on cooling systems or switch off heating systems when equipment gets too hot.

Commonly used with hydronic heaters, this thermostat senses the temperature of liquids. The thermowell protects the sensor.

Regulate line-voltage HVAC systems.

Set these thermostats to adjust the temperature at certain times each day. They regulate heaters that use direct electrical power, such as baseboard and wall heaters.

Commonly used with hydronic heaters, this thermostat senses the temperature of liquids. The thermowell protects the sensor.

Place sensor in enclosures or different rooms than the rest of the thermostat to control temperature from outside the space.

Regulate temperatures in washdown areas for HVAC systems that use direct electrical power, such as air conditioners and heaters.

Keep electronics in your enclosure from getting too hot or cold with these thermostats that control two devices at once.

These thermostats work with low-voltage HVAC systems that have only one speed.

If ambient air temperature rises above or falls below an actuation point, this thermostat flashes the current temperature reading on the display and shows a “high” or “low” message.

Since these switches don’t have a housing above the probe, they are often used in tight spaces and low-clearance areas.

Install the threaded probe directly into tanks, pipelines, and other process components to turn heating equipment on or off at a specified temperature.

Often used in hazardous locations, such as chemical plants, refineries, and grain elevators, these switches have a housing that’s UL listed for environments with flammable gases, combustible dust, and ignitable fibers.

Safe for use in chemical plants, refineries, and other hazardous locations, these switches maintain your surface’s temperature by turning equipment on or off when they reach a set temperature. They’re FM approved for use where flammable gases may be present.

These temperature switches mount on walls and take remote temperature readings with a probe on a cable.

Housing is UL listed for environments with flammable gases, combustible dust, and ignitable fibers, such as chemical plants, refineries, and grain elevators.

Send signals to trigger two different processes, each with their own set temperatures.

For protection in washdown conditions with splashing water, corrosive liquid, and dust, these controllers have a wall-mount housing that meets NEMA 4X. They’re ideal for systems with rapid, unpredictable, or complex temperature changes.

For high accuracy in applications with fluctuating conditions, these controllers have proportional-integral-derivative (PID) software with fuzzy logic that learns system behavior and automatically compensates for changes.

Install these controllers in DIN panel cutouts to maintain your heating equipment’s temperature. When your machine gets too hot, they turn it on and off in short cycles to cool it down.
