Obsolete: IS - Intermittent Steam Purge Bundles for Freeze Protection
Brand: Parker HannifinParflex IS - Intermittent Steam Purge Bundles are thermally insulated with a composite layer of fiberglass that allows for occasional, high-temperature steam purge up to 1100°F (593°C) while ensuring freeze protection during winter through the use of self-regulating heating cables.
The bundles are properly insulated to ensure that the outer surface area of the bundle remains at or below 140°F (60°C) during steam purge conditions at the highest specified ambient temperature, meeting NEC Personnel Protection Code 427.12.
Standard Parflex IS designs come with an internal tinned copper braid on the heating cable for grounding purposes and a Fluoropolymer jacket over the heater to provide additional protection against harsh environments.
The intermittent design permits the bundles to be steam purged for a period of 5 minutes once a day.
During steam purge, the outer jacket surface temperature will not exceed 140°F (60°C). Review the literature provided on the Product Support tab for more information regarding Parflex IS - Intermittent Steam Purge Bundles.
