Caltherm is the UK’s leading manufacturer of top loading ovens — also known as well ovens or well dryers.
Our top loading/well ovens can be engineered for virtually any application – from finishing lines to advanced aerospace thermal processing systems – and are fully customisable to meet your exact process requirements.
Easily loaded using an overhead crane or hoist, top loading ovens (or well ovens) are ideal for heavy or bulky components. These vertical-loading ovens can be built as standalone units or integrated into manual or automated lines. Thanks to their vertical chamber design, they typically require less floor space than traditional front-loading ovens, making them perfect for compact manufacturing environments.
Whatever your requirements, Caltherm can design, manufacture, install, and commission a bespoke top loading/well oven to match your specifications. Every unit undergoes rigorous quality and safety testing, including full product trials, before dispatch.
We additionally supply front loading oven configurations for operations where horizontal access and ergonomic loading are required.

Front Loading Industrial Ovens Also Available
In addition to our top loading models, we also offer a full range of front loading industrial ovens designed for applications where easy horizontal access is essential. These ovens provide excellent ergonomics for loading and unloading, especially when working with heavy components, large batches, or production setups that rely on trolley or rack systems.
Our front loading ovens deliver the same high standards of performance, temperature uniformity, and durability as the rest of our range, and can be fully customised to meet your specific process requirements.
