An electrically heated batch oven with a maximum temperature of 400°F (205°C) will be used by an aerospace manufacturer to composite cure parts. Combination airflow provides both horizontal and vertical upward airflow, which maximizes heating rates and temperature uniformity.

Used to finish batch loads of metal parts, No. 828 has workspace dimensions of 26 x 26 x 38”. The 500°F (260°C) cabinet oven has 6.6 KW installed in Nichrome wire heating elements.

In an interview with Editor Linda Becker, Despatch Industries’ Rolf Kragseth shares further insights about drying products with solvent loads — the type of drying typically done in Class A ovens.

Drying applications vary: from drying frac sand — a relatively simply process often performed for screening purposes — to applications like drying wetted primer in ammunition — a process that depends on accurate temperatures sustained over time. Yet, in drying applications from simple to complex, airflow and temperature uniformity makes a difference.

A batch oven will be used for aging aluminum exterior components for aircraft engines. Wisconsin Oven, East Troy, Wis., manufactured the indirect gas-fired aluminum aging oven for the automotive and aerospace parts manufacturer.

An electrically heated, enhanced-duty batch oven will be used for preheating and tempering steel components. Wisconsin Oven Corp. shipped the heating system with a powered load car to a heavy equipment manufacturer.

The 500°F (260°C), top-loading oven can be used for applications such as drying water from racks of piston rings. Workspace dimensions of this oven measure 48 x 48 x 36", and 40 KW are installed in Incoloy-sheathed tubular heating elements.

Used for curing epoxy, No. 942 is a gas-fired, 350°F (177°C) walk-in batch oven. Workspace dimensions measure 84 x 144 x 108", and 400,000 BTU/hr are installed in a modulating natural gas burner to heat the unit.

A composites maker will use an electrically heated, batch core-forming oven for its patented process of forming honeycomb material for aircraft engines.

An electrically heated 750°F (399°C) walk-in oven, No. 941 is used for drying resin mixtures at one customer’s facility.
