Type M-T-PFA (PFA Teflon)

High Temperature – Constant Wattage

Features

PFA Teflon
Entire construction employs Dupont PFA Teflon which is unaffected by chemicals and solvents that may cause rapid deterioration of other plastics and all but the most expensive metal alloys.  High resistance to moisture, flame, and radiation is also realized.

Optional Nickel Plated Bus Wires
For maximum thermal and corrosion protection.

Constant Wattage
Uniform heat; wattage remains the same regardless of circuit length.

Zone Modules
Hand soldered and inspected to maintain 100% contact with bus wires.

Cut to Length on Site
Parallel resistance type heater eliminates the need for inventories of different size heaters.
