Heating Liquids

Heating a liquid can be accomplished using any of several heater types and/or a combination of types. Some heaters physically lend themselves to direct immersion in the liquid, while others are better suited for heating a pipe or vessel containing the liquid. The application descriptions below will give you a general idea on how a particular heater type is applied to heating liquids and some common examples.

Band Heaters

Clamped to exterior or interior cylindrical surfaces.

Applications

• Freeze protection of liquids in pipes
• Heating liquids in processing lines

Cable Heaters

Wrapped around a pipe or vessel containing a liquid, as an immersion heater, or coiled inside a short section of tubing to form a circulation heater. Often used in applications with limited space.

Applications

• Photo processing equipment
• Scientific instruments
• Heat tracing

Cartridge Heaters

Mounted with a screw plug or placed in a protection well. Direct immersion recommended for water or 90+ percent water soluble solutions.

Applications

• Food preparation
• Laboratory equipment
• Boilers

Ceramic Fiber Heaters

Heater panels assembled into a chamber that surrounds a tank, vessel, crucible or bath. Made-to-Order heaters can accommodate sinuated tubing and more. Radiant and convection heat transfer heats the load.

Applications

• Fluidized beds
• Non-ferrous metal melting and holding

Flexible Heaters

Bonded or vulcanized to the surface of a pipe or vessel. Well suited for curved and irregular shaped objects.

Applications

• Freeze protection
• Respiratory therapy units
• Hydrotherapy baths

Strip Heaters

Bolted or clamped to the flat wall of a tank or vessel. Used in applications offering a suitable mounting surface and location.

Applications

• Freeze and moisture protection
• Food warming
• Tank heating

Tubular and Immersion Heaters

Most often used for immersion heating as screw plug, flange, circulation or over-the-side heater assemblies. Elements can also be clamped to a tank wall. Well suited for high kilowatt requirements.

Applications

• Deionized water rinse tanks
• Chemical baths
• Heat transfer fluids
• Vapor degreasers
