Innerline Heaters

This unique family of products is the industry-standard for excellence in water systems for freeze protection down to -65F. They provide 100% efficient heating through direct immersion of the heating element in potable or gray waterlines. These high reliability heaters offer significant cost benefits over common tape heaters by eliminating labor intensive wrapping and insulation. They are inherently safe, as the potential of "bridging burn-outs" (due to improperly installed or damaged heaters) is eliminated. Innerline Heaters are completely safe for dry pipe operation and comply with FDA requirements for materials in contact with potable water.

  • 2880 Series Heaters - include temperature sensor and self-contained controller (zero-cross electronics) meeting EMI requirements for sensitive fly-by-wire aircraft applications. Additional user selected options include remote temperature sensing and self-test circuitry.

  • 2941 Series Heaters - include an additional temperature sensor for remote, aircraft-supplied control and over-temperature protection. Optional thermostatic control is also available.

  • 3046 Series Heaters - an economic solution to waterline freeze protection consisting of a basic heating element only.

  • Innerline and Thinnerline Heater Elements are available in lengths up to 65 feet (19.8 meters) and power outputs up to 12 watts per foot (39.4 watts per meter). The standard Innerline Heater element diameter of 0.19 inches (4.8 mm) is suitable for a waterline with an inner diameter of 0.5 inches (14mm) or greater. Our Thinnerline Heater element has a diameter of 0.13 inches (3.3 mm) and is available for waterlines with diameters less than 0.5 inches (14 mm), typically used on business or regional jets.

  • Temperature Control Settings for Cox's 2880 Series Innerline Heaters are available in standard or remote temperature sensing versions with a standard set-point of approximately 65F. Other temperature control settings are available upon request. Customized Innerline Heater products and systems are available to meet specific customer applications.
