Install these air conditioners in an opening in an exterior wall.

Produce twice as much cool air as standard mobile evaporative air coolers.

Be comfortable year-round with units that cool and heat your space.

Protect equipment in enclosures and cabinets from overheating with chilled air.

Suitable for washdown applications, these air conditioners are rated NEMA 4X to resist dirt, washdowns, and corrosion.

Set the thermostat and these vortex tubes switch on only when needed.

In addition to being quieter than standard enclosure-cooling vortex tubes, these stand up to washdowns and weather. They convert compressed air into a stream of cold air to keep electronics within enclosures from overheating while also keeping dust and other contaminants out.

These NEMA-rated vortex tube are designed to keep water out during washdowns.

Quietly cool electronics inside enclosures to your desired temperature while keeping out rain, snow, splashing water, and dirt.

Quietly cool electronics inside enclosures while keeping out rain, snow, splashing water, and dirt.

Tablets gradually dissolve, preventing deposits from developing on the pan.

Kits include a handle and six interchangeable heads to fit a variety of fin spacings.

Pump liquid and vapor refrigerant out of a system and into a refrigerant cylinder.

Monitor refrigerant pressure on an LCD when servicing air conditioning systems.

Dispense programmed amounts of refrigerant.

Remove moisture and contaminants from your system to prevent corrosion and maintain efficient operation.

Kits include one vortex tube for converting compressed air into a stream of cold air as well as airflow adjusters, a cold-air muffler, a tube fitting, and tubing.

Control one- and two-speed heaters and air conditioners.

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.

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

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

Control a single heating or cooling device in your enclosure to keep electronics at a safe operating temperature.

Brush or spray on; then rinse off. These cleaners contain sodium hydroxide for tough jobs.

Each hose is a different color so you can differentiate your lines.

Prevent condensation from forming on refrigeration and air conditioning lines and cold‐water piping.
