PTEF Single Tubular Spiral Heaters

Introduction:

Over the side vertical or horizontal bottom position heater constructed of thick gauge metal elements covered with 

heavy wall fluoropolymer (PTFE).

Offers outstanding 10watts/square inch of heating capacity and a corrosion resistant terminal enclosure.

The PTFE Jacked SINGLE SPIRAL Tubular Element Series is an Over-the-Side Vertical Or Horizontal – Bottom heater 

designed to offer superior performance utilizing 10 watts per square inch (1.5w/cm²) of heating capacity. Fluoropolymer 

(PTFE) heaters are an excellent choice for heating Aqueous acid, alkaline, anodizing and pickling solutions up to 212°F 

(100°C).

The heater head (terminal enclosure) is available in Nema 4X compliant (consult factory) or vapor tight, corrosion resistant 

– flame retardant polypropylene, equipped with 3 foot (.9m) corrosion resistant thermoplastic flexible conduit.

This product offers thick gauge stainless steel tubular elements covered with heavy wall fluoropolymer (PTFE) reducing 

permeation, eliminating the need for gas purge systems. This product is an excellent choice for heating electroless chemistries 

– not for use in Chromic Acid.

 Characteristics 

~Excellent Chemical resistance

Durable heavy wall fluoropolymer (PTFE) encases the stainless steel tubular elements offering maximum chemical resistance.

~Superior Performance

Low watt density, 10 watts/sq.inch (1.5w/cm²) minimizes buildup for longer heater life. Fast heat dissipation.

~ Excellent Uniform Heating

Over the side design parallel to tank heating.
Bottom design heater section provides even heating with varying liquid levels.

~Corrosion Resistant Terminal Enclose Head

Vapor tight, corrosion resistant – flame retardant polypropylene terminal enclosure with 3 foot (.9m) flexible corrosion resistant thermoplastic flexible conduit. Available in NEMA 4 compliant enclosure (consult company for specifications).

 ~Safety Features

-Grounded internal stainless steel elements.
-Over Heat Thermal Fuse Protector is built in (Option A), suitable for solutions up to 190°F (88°C). Available with automatic reset or manual reset thermal protection. Consult factory for available options.

² Voltages

500 to 9,000 watts at 120, 240, 480 volts. 208, 380, 415 and 600 and other custom voltages available. (Consult company)
