Description

Type RPA Industrial Electric Heating Tapes are Constant Watts Output electrical heaters supplied in fixed lengths, with factory-made cold-lead terminations.

Multiple-element woven construction provides high mechanical
strength combined with reduced electrical and thermal stresses on the heating element.

The RPA heating elements are individually insulated in PFA
integrally woven into a glass fibre carrier.

An optional copper wire over-braid can be applied (RPA/BR).

Cold-leads are made from silicone rubber insulated cable. Standard cold-lead length is 500mm..

Units are highly resistant to moisture and most chemicals. Flame and radiation resistance is very good.
B.S. 6351 Grade: RPA (2.1) RPA/BR (2.2).

Field of Application:

RPA heating tapes are designed for maximum versatility. They can be used in a wide range of applications, maintaining flow temperatures of process lines or providing frost protection of water lines in chemical and petro-chemical and food processing plants, oil refineries, power generation, water treatment plants, mines.

Temperature maintenance of heavy fuel lines (including pumps, valves and strainers) caustic solutions, waxes, fats, glucose, chocolate. Frost protection of water lines, safety showers, sprinkler systems, drain lines, steam purged lines.
