L-SHAPED IMMERSION HEATERS

Our L-shaped heaters are designed to maximize application flexibility and minimize installation costs. Compared to other standard Immersion Heaters, such as Over the Side, Side Wall, and Tank Heaters, an L-shaped immersion heater delivers heat at the bottom of the tank making it safer for tanks with lower liquid levels. Explore the features and capabilities of our L-shaped immersion heaters to discover the customizable solutions that can improve the safety and efficiency of your project, application, and industry.

L-Shaped Heater Features

Each custom-made L-shaped immersion heater is designed to fit your requirements, including different sizes, materials, and wattage.

Mounting Options

An L-shaped heater can be top-mounted into tanks and drums keeping the terminal enclosure at the top while applying heat at the bottom of the tank.

Easy Installation

The L-shaped design allows for easy installation and removal for cleaning or use in multiple tanks. L-shaped heaters do not require tank drainage for heater removal.

UL Listed

UL Listing means that UL has tested representative samples of a product and determined that the product meets specific, defined requirements. (Excludes L-Shaped heaters with Thermostat and Titanium)

Terminal Box

Rugged terminal boxes provided for wiring connections on our custom L-shaped immersion heaters. NEMA 4 terminal boxes are standard and NEMA 4/7/9 terminal boxes are available upon request.

Straight, Circular, or Custom

Standard immersion heater models with straight or circular elements (sometimes called O-Shaped) are designed to fit most tank and drum configurations. If our standard models don’t fit, our L-shaped immersion heaters have a variety of dimensions, heater sheath materials, and capabilities available.

Materials Available

Talk to us about which material is best for your application, and we will find a solution that works for your project. Sheath elements for our L-shaped heaters are available in Stainless Steel, Titanium, and Incoloy®. The riser is available in Stainless Steel and Titanium.

Thermostats

Thermowell and thermostats are available to improve the safety and efficiency of your L-shaped immersion heater.

Puts Heat at the Bottom

An unheated vertical riser makes L-shaped heaters a safer option for tanks with lower liquid levels.

Heatmax History

Founded by an ex-Navy engineer, George Strokes, the company got its start making quartz immersion heaters in Euclid, Ohio in 1952.

George called the company Glo-Quartz®.

Growing rapidly he moved the company to bigger premises in Willoughby and then Mentor. Other factories were opened in Pasadena, California (now closed) and then Tucson, Arizona.

Tom Strokes took over leadership of Glo-Quartz in the mid-70s and moved to roll reduced metal heating element range.

A final legacy, Tom launched a new brand name, Heatmax Heaters, in 2020. The new brand name both better represented the wide range of products we make and challenged the common perception that we were quartz heater specialists only.
