Induction Coil Refurbishment
Inductotherm Heating & Welding offers a complete refurbishment service for the many types of induction coil which are in operation with our induction heating power supplies from the Banyard, Radyne and Newelco brands.
Today’s market conditions will often determine that it can make good economic sense to have an existing, well used and even partly damaged induction coil completely refurbished – rather than have it discarded and replaced by a brand new one.
Prior to returning units for total refurbishment, Inductotherm Heating & Welding recommends that photo of the subject coil(s) are forwarded to the spares department for an initial assessment. An on-site inspection can also be carried out by an our highly skilled engineers at minimal expense to the customer if required.
During the annual shutdown period it is becoming increasingly popular for customers to take a coil out of service and replace it with a spare unit from their stock. A coil change-out programme such as this will enable the customer to carry out a planned refurbishment with no costly production downtime.

Offshore Induction Coil Refurbishment
Our offshore Merlin and Clam Coils require specialist knowledge and tailor made assessments to ensure the durability and reliability of the equipment in the harshest of conditions.
After carrying out the refurbishment, offshore heating coils are drained down then winterised by the addition of anti-freeze solution in order to facilitate winter storage (if necessary) prior to redeployment.
