Dye Penetrant Inspection (DPI) Equipment

Bespoke Drying Ovens

Industrial Drying Ovens

Programmable multi-purpose Drying Ovens

Bespoke programmable industrial drying ovens designed and manufactured in-house and tailor made to meet customer requirement - Ranging from drying ovens small enough to sit on work benches to much larger ovens measuring several meters in length. Ovens are of Stainless Steel construction, using quality components and built to last. Ideal for speeding up inspection procedures making it possible to test larger volumes of components compared to air drying methods.

Johnson & Allen consider all builds. While we typically make ovens for use in NDT sector we have previously built ovens for many other varied applications.

Thermostatic Control

Typically maximum oven temperatures are either 75°C or 120°C depending on the heating element with thermostatic control built in as standard. Ovens also include inter-wall insulation and have fan assisted heating to achieve uniform internal temperatures. Drying ovens are supplied fully calibrated and include a temperature distribution survey with measurements at multiple positions to verify internal temperature uniformity.

High Efficiency Design

All drying ovens are designed to recirculate air - By recirculating air ovens can often warm up quicker and it also increases running efficiency - Giving notable running cost savings in the long run.
