Features■HeavyDutyConstruction Hubbell electric immersion heaters are constructed using

only the highest grade materials and are put through a rigorous quality assurance testing procedure to ensure that each heater conforms to specification.

■WideSelection Hubbell electric heaters are fabricated in a wide variety of

types and styles including cartridge heaters, screw plug heaters, and flanged heaters.

■Delivery Hubbell maintains a large inventory to meet even the

most demanding delivery requirements.

ElectricImmersionHeaterConstructedForLongServiceLife Hubbell electric heaters have been in service since 1920. In that time Hubbell engineering, production, and quality control systems have been continually refined to ensure that each electric heater performs to the highest standards. Available in virtually any configuration, Hubbell electric heaters are manufactured to meet the

requirements of the most demanding application. So whatever fluid type you are heating, you will have confidence in knowing that when you specify and install a Hubbell electric heater the owner will be provided with a trouble-free and long lasting product.
