Hi Limit Controls

ITW EAE –Despatch Recommends

A Hi-Limit control for ALL Ovens and Furnaces

A HI-LIMIT CONTROL IS INCLUDED ON THIS EQUIPMENT.

IT IS INSTALLED TO PROTECT THE EQUIPMENT.

The location of the Hi-Limit Sensor is at the supply duct louver and has been

chosen to supervise that temperature. The Hi-Limit controller should be set to

approximately 5⁰C to 10⁰C (9⁰F to 18⁰F) higher than the maximum operating

temperature. This setting will eliminate nuisance shutdowns when operating at

the maximum temperature of the equipment and still give maximum protection

to the equipment.

ITW EAE CANNOT BE RESPONSIBLE FOR EITHER THE PROCESS

OR QUALITY OF THE PRODUCT BEING PROCESSED.

If the product on which the equipment is being used is critical of over

temperature, the Hi-Limit may be used as a “Process Hi-Limit”. The sensor

element is located on the supply duct where the hot air enters the work chamber.

The temperature setting on the “Process Hi-Limit” should be set somewhat below

the temperature at which the product would be damaged. If the product has an

ignition temperature at which it would ignite, the setting should be well below

this temperature. It is recommended that a certified instrument be used to make

proper setting.

IT IS THE PURCHASER’S RESPONSIBILITY THAT THE “EQUIPMENT” HI-

LIMIT AND/OR THE “PROCESS” HI-LIMIT BE SET PER THE

INSTRUCTIONS ON THIS SHEET AND ALSO THE INSTRUCTION SHEET

FOR THE PARTICULAR HI-LIMIT INSTRUMENT FURNISHED WITH THIS

EQUIPMENT.
