Caltherm designs and manufactures industrial box ovens in the UK, custom built for curing, drying, ageing, annealing, and heat treatment. Also known as batch ovens, these versatile systems process materials in discrete loads rather than continuously, making them the ideal choice where flexibility, varied components, or changing production schedules are involved.
With over 40 years of experience, and box ovens as the very first products Caltherm built back in 1978, every oven is designed, fabricated, and pre-commissioned at our Staffordshire facility before dispatch.

Frequently Asked Questions
Are box ovens the same as batch ovens?
Yes, the terms box oven and batch oven are used interchangeably. Both describe an oven with a rectangular chamber that processes materials in individual loads or batches, rather than continuously on a conveyor. At Caltherm, we design and manufacture custom box and batch ovens for curing, drying, and heat treatment across a wide range of industries.
What is an industrial box oven used for?
Industrial box ovens are used for thermal processes including curing, drying, ageing, annealing, preheating, and general heat treatment. Their flexible batch format suits varied components and production schedules across aerospace, automotive, composites, and general manufacturing.
What temperatures can a box oven reach?
Caltherm box ovens are available in low, medium, and high temperature models, ranging from ambient +10°C up to 700°C. For processes above this, we manufacture a full range of industrial furnaces.
Should I choose a batch oven or a conveyor oven?
Batch ovens suit varied loads, mixed components, and flexible production schedules. If you process high volumes of similar parts continuously, a conveyor oven may be more efficient. Our engineers can advise on the right configuration for your throughput.
Can your box ovens be integrated into a production line?
Yes. Caltherm box ovens can be fully integrated into existing or new production lines, with automation interfaces, loading systems, and tailored controls designed around your workflow and space.
Are your ovens CE and UKCA compliant?
Yes. All Caltherm industrial ovens are CE and UKCA compliant, and we manufacture to AMS2750H with Nadcap support for aerospace customers.
