Safety Guidelines

The safety and performance of this heater is dependent on proper
handling, installation, control and maintenance. As Chromalox can not
anticipate all conditions under which this information and heater, or
this heater in combination with other manufacturer’s products may be
used, it is advised that you conduct your own tests to determine the
safety and suitability of this heater in combination with other products
in your application. Where the consequences of overheating or failure
could result in personal injury or property damage, back-up controls
and safety devices are essential.

The Safety Alert Symbol: is found throughout these installa­tion instructions to identify potential hazards that can result in person­al injury. The seriousness of the potential risk is identified by one of
these three words:

– will result in serious injury or death.

– could result in serious injury or death.

– may result in minor or moderate injury.

Read and follow these instructions to minimize risks of electric

shock or fire. Save these instructions for future reference.

Chromalox Type TLC, TLO,TLS,TLI, KTLC, KTLO, KTLS,
KTLI, KBLC, KBLS, BLCK, & BLCS series industrial Over-The­Side immersion heaters are designed for a wide variety of heating
applications.

1. Heater Construction Characteristics

A. High quality resistance wire held in place by compacted

Magnesium Oxide Refractory or compacted proprietary
cement enclosed in a wide variety of sheath materials.

B. Low to high watt densities.

C. Standard selection of sheath materials include copper, steel,

INCOLOY

®

alloy and stainless steel. This broad selection of
sheath materials will operate successfully in many corrosive
solutions.

GENERAL (cont’d.)

D. Riser type construction puts the heat at the bottom inducing

natural “stirring action” and evenly distributed temperatures.

E. Units are available with E1 General Purpose, E4 Moisture

Resistant, E2 Explosion/Moisture Resistant and E3 Explosion
Resistant terminal enclosures.

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. CHROMALOX
cannot warrant any electric immersion heater against
failure by sheath corrosion if such failure is the result
of operating conditions beyond our control.

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