02. Security _

█Super long service life ✔

HTU + is an ultra-high temperature self-regulating heating cable. It has been greatly improved in terms of product indicators and design service life. At the same time, it can also have higher output power in high temperature environments, so it can be applied to applications with high temperatures piping and equipment to maintain temperature requirements, and frost protection needs at high exposure temperatures. The product design life is not less than 30 years and provides a 10-year warranty.

03. Stability _

█Super stable power maintenance ✔

1st Experiment:

In accordance with Chapter 5.1.12 of the IEC/IEEE 60079-30-1 standard, after completing 1500-cycle hot and cold cycle tests, the power of the sample tape showed no attenuation and the power retention rate was 100%, which proved that the HTU + series products can guarantee normal power output under harsh application environments.
