Ideal in systems with rapid, unpredictable, or complex temperature changes, these controllers turn heating equipment on and off using a proportional-integral-derivative (PID) control algorithm to make fine adjustments, giving you the most precise and stable temperature control.

Mount these temperature controllers directly onto DIN rail for controlling systems with rapid, unpredictable, or complex temperature changes. They turn heating equipment on and off using a proportional-integral-derivative (PID) control algorithm to make fine adjustments, giving you the most precise and stable temperature control.

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.

Rated IP65 and NEMA 4X to seal out water and dust, these temperature controllers turn your equipment on and off in areas with frequent washdowns.

Regulate the amount of power flowing to your heater with the turn of a dial. Instead of a temperature sensor or input, these controllers work like a dimmer on a light switch.

To control heating equipment in washdown environments with splashing water, corrosive liquid, and dust, these switches have a housing that meets NEMA 4X.

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.

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

To protect these switches from splashing water, corrosive liquid, and dust, the housing meets NEMA 4X for washdown conditions.

Often used to control heat cable output, these switches maintain your surface’s temperature by turning equipment on or off when they reach a set temperature.

Install directly into drilled and reamed holes.

An adjustable reset lets you control the amount of temperature change, also known as deadband and differential, before these switches reset. When they reach the set temperature, they send an electronic signal to your programmable logic controller (PLC) to turn equipment on or off.

Plug in the thermostat, then plug your heater into the socket on the thermostat's plug.

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

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.

Use to regulate line-voltage HVAC systems where flammable gases, vapors, and dust are present. Thermostats are rated Class I, Divisions 1 and 2, Groups C and D; and Class II, Divisions 1 and 2, Groups E, F, and G.

Control, monitor, and program your HVAC system from anywhere. These thermostats connect to a Wi-Fi network, so you can use a computer, tablet, or smartphone to view and adjust settings.

Set these thermostats to adjust the temperature at certain times each day.

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

As the temperature goes up, the pressure in the system goes up.
