An adjustable thermostat automatically turns the heater on when the temperature drops below your set temperature and off when it rises above your set temperature.

Also called tankless water heaters, these provide hot water on demand and take up less space than heaters with a tank.

Install these heaters into threaded container openings or pipe couplings to quickly and efficiently heat liquid through direct contact.

Often used for temporary heating in sinks and pails, these heaters have a circular base that sits at the bottom of containers. Remove them from the container after heating its contents.

Sized to fit drums, these heaters have a bracket to hook on the side of drums and in bung openings.

Often used for freeze protection in outdoor containers, these heaters float on the water’s surface and automatically keep the temperature between 45° and 65° F.

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.

Place these flat-panel heat exchangers in open tanks to heat or cool their contents by transferring heat from liquid or steam that flows through passageways in the panel.

Cool hot liquid samples to safe temperatures for testing. These heat exchangers are often used to monitor boiler water quality without shutting down the system.
