Ten Reasons to Choose Caltherm



We are confident when we say that you won’t find another manufacturer with our experience and expertise.


Caltherm started in 1978 as a local engineering company supplying industrial mechanical, electrical and, particularly, gas engineering services.


Now, 40 years later, with three generations of the same family on the same site where it all began in 1978, Caltherm are Britain's leading industrial oven, furnace and dryer manufacturer.




At Caltherm quality is key. When you work with the most prestigious names in the aerospace and automotive industries, electrical and engineering, composite, rubber and plastics manufacturers, glass and pharmaceutical firms, there is no room for error.


With vast experience working to standards such as AMS2750E for the aerospace industry, Caltherm are meticulous when it comes to the detail that goes into our design and manufacturing process.


This also carries through to our smaller projects. Whether you are ordering a small box oven or a specialist furnace, the same amount of care and attention goes into every project we undertake.


We Are a One Stop Shop


From the moment you make your first call to Caltherm to the finished product arriving on site and being installed and commissioned, the whole process is handled from our one site in Newcastle-Under-Lyme.


We have a small dedicated sales team who will be with you every step of the way to deal with any queries and help develop the right product to suit your requirements.


We have our own design team, designing in CAD and using 3D to bring the concept to life.


We design and build our own control panels with directly employed electricians.  All frame fabrication, sheet metalwork, mechanical fitting, etc. is completed in-house by Caltherm employees.


Installation, commissioning and training at the customer's site is also carried out by Caltherm fitters and electricians.


We are with you every step of the way and Caltherm is the only company you will deal with during the process.


After Sales Care


Our relationship with our customers doesn’t stop once a sale is complete. Any queries or questions that you have post sale are dealt with by the same people who you will deal with during the sales process. At Caltherm we don’t have a Customer Service department because we have never needed one!

Just call us up and speak to the same familiar faces you dealt with previously. We are always happy to help.




Caltherm offer a standard 12 month Warranty with all of our products. Once this warranty expires it is important to have a maintenance contract in place to ensure that your equipment stays in tip top shape.


Who better than to maintain the equipment than the company who designed and manufactured it. We can offer fully comprehensive service and maintenance contracts at competitive rates to ensure that you always have piece of mind that your equipment is safe and operating as it should be.
