OBSOLETE: SL - Self-Regulating Temptrace™ Bundles for Low Temperature Maintenance

Parflex SL-Self-Regulating Temptrace™ Bundles are designed to provide freeze protection and low temperature maintenance for gases, liquids or other viscous materials in chemical processing and refinery applications. The tubing is thermally insulated with a non-hygroscopic inorganic fiberglass material and protected with a flexible, black, flame-resistant PVC jacket for added protection. The thermal insulation allows for the transfer of fluids or gases up to 185°F (85°C) while maintaining an outer jacket surface temperature of 140°F (60°C), meeting NEC Personnel Protection Code 427.12. Standard SL designs come with an internal tinned copper braid on the heating cable for grounding purposes and a TPR jacket over the heating cable to provide additional protection against many inorganic chemical solutions. For order details, refer to our latest literature on the Product Support tab.
