Hook these heaters on the side of small drums and pails to quickly and efficiently heat liquid through direct contact. All are for use in metal containers; they should not be used in plastic containers. An adjustable thermostat automatically turns the heater on when the temperature drops below the set temperature and off when it rises above the set temperature. Adjust the set temperature with the dial. The heating element is 316 stainless steel for excellent resistance to harsh chemicals.

Note: Immerse the heating element in liquid up to at least the minimum coverage level to prevent heater failure.

To heat oil and coolant without creating hot spots and damaging the heating element, these heaters have a lower watt density than heaters for water or chemicals. They install into threaded container openings or pipe couplings to quickly and efficiently heat liquid through direct contact.

Heaters without temperature control require a temperature switch or controller (sold separately) to regulate heat output.

Heaters with an adjustable thermostat automatically turn on when the temperature drops below the set temperature and off when it rises above the set temperature. Adjust the set temperature with the dial.

Incoloy heating elements are more corrosion resistant than steel heating elements.

Note: Fully immerse the heating element in liquid to prevent heater failure. These heaters install through threaded container openings or pipe couplings.

Also known as shell and tube heat exchangers, these transfer heat using liquid or steam that flows through the shell to heat or cool liquid in the tubes. They’re commonly used in refrigeration and engine cooling systems. Btu/hr. cooling capacity is based on cooling 180° F process water with 85° F water and a 10 psi pressure difference.

Heat exchangers with a 316 stainless steel shell and tubes are the most corrosion resistant.

Heat exchangers with baffled tubes direct liquid to make four passes through the tubes for more efficient heat transfer than other heat exchangers.

ASME BPVC VIII.1 heat exchangers meet the ASME Boiler and Pressure Vessel Code (BPVC) for construction of pressure vessels.

Stacked, corrugated plates maximize contact with liquid or steam flowing through these brazed plate heat exchangers for faster heat transfer than shell and tube heat exchangers. Plates are brazed in a vacuum furnace to ensure 100% sealed construction.

Copper-brazed heat exchangers have a Btu/hr. cooling capacity based on cooling water from 120° to 100° F using 70° F water.

ASME BPVC VIII.1 copper-brazed heat exchangers have a Btu/hr. cooling capacity based on cooling 100 SSU oil to 125° F using 85° F water.

Nickel-brazed heat exchangers have a Btu/hr. cooling capacity based on cooling oil from 140° to 120° F using 70° F water.

ASME BPVC VIII.1 heat exchangers meet the ASME Boiler and Pressure Vessel Code (BPVC) for construction of pressure vessels.

With more than three times the pressure rating of standard heat exchangers, these are often used for high-pressure condensing, evaporating, heating, and cooling. Also known as shell and tube heat exchangers, they transfer heat using liquid or steam that flows through the shell to heat or cool liquid in the tubes. Btu/hr. cooling capacity is based on cooling 180° F process water with 85° F water and a 10 psi pressure difference. Shell and tubes are 316 stainless steel for excellent corrosion resistance.

Often used to monitor boiler water quality without shutting down the system, these heat exchangers cool hot liquid samples to safe temperatures for testing. Sample liquid flows through the tubes, and cold water from an external water supply flows around the tubes to cool the liquid in the tubes.

316 stainless steel tubes have the best corrosion resistance.

Roll these powerful space heaters to where you need heat for big jobs. All have a built-in thermostat.

The electronic spark ignition makes them good for drafty areas where a pilot light could be extinguished. The safety shut-off cuts the gas supply if the flame goes out.
