Here's how some of our customers use this product...

Preventing Boiler Stacks from Overheating

The Background: The customer is a large industrial plant that needs a solution that provides protection against overheating the boiler stack. If the stack temperatures exceed 750˚F, the burners must be shut down to avoid damaging the equipment.

The Problem: The high temperatures encountered at this plant are outside the range of many temperature switches or limit controllers.

The Solution: The customer selected the Ashcroft G Series Temperature Switch which is ideally suited for this application. The G Series is available in temperature ranges up to 750˚F and has a remote mount option so that it can be mounted in the burner cabinet for easy troubling shooting and resetting of the control.
