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.

Wisconsin Oven shipped two steam-heated batch ovens to a manufacturer of industrial products.
