Box Ovens
Numerous processes used in today's manufacturing industries need the application of heat for either the curing, stoving, drying, annealing, pre-heating or baking of a product or a coating. These can be undertaken using a modern effiecient Box Oven.
Where the work piece is simply not suitable for hanging on a conveyor, where the quantity to be processed isrelatively small or where there is a variety of product shapes and sizes to be processed then a forced air recirculation Box, or Batch Oven as it is sometimes called, proves invaluable.

Whether it's curing composite materials, powder coatings, plastic components - or drying insulation materials, lacquer finishes - or pre-heating and annealing components all these applications present manufacturers with a number of challenges such as:

- Curing the finish on a product without running the risk of it scorching, before it is fused to the products surface. As could be the case when using infrared Ovens.
- Providing and maintaining uniformity of temperature for critical application such as in the Aerospace industry where AMS 2750 D specification and Rolls Royce specification RPS 953 are the norm.
- Providing sophisticated yet easy to use temperature controls for the heat treatment of metals as, defined in BS 2M 54.
- Fulfilling safety and operational requirements in compliance with BS EN 1539 and HS(G) 16.
- Accommodating product components that may be on trolleys, racks, shelves or multi-rail loading systems.
A Forced Air Recirculation Box Oven addresses all these problems because:
- Even temperature is provided by the Ovens warm air recirculation system thereby eliminating the risk of scorching a surface finish.
- High air recirculation volumes at low pressures ensure close uniformity of temperature, with ±5°C being readily achievable.
- The Ovens control and monitoring system can be tailored to suit the specific application.
- Box Ovens designed and constructed by an accredited and BS EN ISO 2001 approved manufacturer will ensure compliance with all safety and operational requirements.
- Side hinged double doors, vertical lift doors, manually operated or fully automated can all be incorporated into the Box Oven design so as to provide ease of access for trolleys, racks etc.
On many sites, such as those found in the Chemical and Petro-Chemical industries, the location where the Box Oven is to be positioned is often designated as a hazardous zone, as defined in EN60079-10. For these applications the Ovens have to be designed and rigorously constructed inline with the ATEX directive 94/9/EC - "Equipment intended for use in potentially explosive atmospheres".
Particular care should be taken when purchasing a Box Oven for these applications so as to ensure that the manufacturer is fully aware of the ATEX requirement and has had previous experience in supplying suitably rated Ovens and associated control equipment.
Heated by either natural Gas, LPG, electricity, oil, steam or hot water Box Ovens have been found to be the most economical and practical solution where the heating, curing, drying of a product etc. at elevated temperatures is required.
