GENERAL

FIRE/EXPLOSION HAZARD. This heater is not intend- ed for use in hazardous atmospheres where flamma- ble vapors, gases, liquids or other combustible atmos- pheres are present as defined in the National Electrical Code. Failure to comply can result in per- sonal injury or property damage.

Chromalox type PTH over-the-side immersion heaters are especially suited for use in plating tanks, rinse tanks and other aqueous solutions.

IMPORTANT: It is the responsibility of the purchaser of the heater to make the ultimate choice of sheath material based upon his knowledge of the chemical composition of the corrosive solution, character of the materials entering the solution, and controls which he maintains on the process.

Sheath corrosion can result in a ground fault which, depending upon the solution being heated, can cause an explosion or fire.

Heater Construction Characteristics.

A.High quality resistance wire held in place by compacted mag- nesium oxide in type 316 passivated stainless steel sheath.

B.Medium watt densities.

C.Vapor resistant junction box with 3’ PVC flexible conduit with ground wire.

D.Spacer bar prevents elements from touching tank wall.

E.Flat profile consumes little tank work area.

The system designer is responsible for the safety of this equipment and should install adequate back-up controls and safety devices with their electric heating equipment. Where the consequences of failure could result in personal injury or property damage, back-up controls are essential.
