Spiral Heater Spec Sheet

CHR manufactured preformed silicone spiral heaters to suit pipework and tubular applications, however, manufacturing techniques for standard preformed heaters meant that for small diameter pipes the heater could only be manufactured in short lengths for rigid pipe work. Through continued product development, CHR can now offer the Spiral Wrap Heater range to suit flexible or rigid pipes.

Key silicone spiral heater features

  • Suitable for straight or curved pipe sections<
  • Robust spiral heating element.
  • Easy to install.
  • Can be supplied with incorporated temperature sensor for accurate control with a suitable controller.
  • Stand alone heaters or parallel option to cater for longer pipe runs.

    New application or replacing a previous solution?*

    Can we define the shape & size? If cylindrical what is the OD of the cylinder and length confirmed?*

    Do you have any photos of the vessel to be heated?

    Attach photo/files/drawings. Max file size 4mb.

    Are there any features that need to be accommodated?

    Material the vessel/item to be heated made of?

    Supply voltage desired?

    Amperage available?

    Starting temperature?

    Target temperature?

    Temp. accuracy needed? +/- 5F or more precise <2F?

    Do you require a temperature sensor in the heater? This sensor can work with an existing Temperature Controller if desired

    Do you desire we quote you a Digital Temperature Controller? We can provide both On/Off or PID Logic Enabled Temperature Controllers

    Adhere the heater to the cylinder or do you need to remove it?

    Is the area Classified/Explosion Proof?

    What is the Classification of the area? For example Class 1, Division 2

    It is the heating application outside? If so, will the heater going to exposed to the elements?
