Chemelex / Raychem HTV
Heating cables and assemblies · Process temperature maintenance
HTV is intended for industrial duties with high maintain and exposure temperatures. Pro Therm distinguishes continuous temperature maintenance from short process peaks. This informs output selection and requirements for controls and system components.

A self-regulating cable’s output depends on temperature. Heat loss and the cable output curve must be compared under matching conditions. Cold start, maximum circuit length and protection are assessed separately. Self-regulation does not replace the review of controls, electrical protection and permitted operating conditions.

Can I enquire about this product directly?
First specify the version and quantity in the product finder. For heating cables, provide voltage and output or explicitly request technical selection. Then enter your contact details and submit the form.
Can another manufacturer’s product be considered?
An alternative may be offered after technical review. Output, temperature limits, connections and existing system requirements are assessed together. Cross-brand interchangeability is not assumed.
