Thermal Cleaning Systems

The Winona Van Norman Thermal Cleaning Systems are a next generation of cleaning equipment designed to meet the needs of high production while remaining environmentally friendly. Thermal cleaning removes the need to use harsh chemicals with costly disposal costs.

Each system is based on a modular basket design that allows the work piece and basket to be completely removed from each cell and placed into the next stage while saving time and protecting the operator. Standardized cells can be added to speed up processes or expand production.

Each Thermal Cleaning system consists of a thermal oven, a shot blast cabinet (with dust collector), and a shaker/tumbler cooling unit. Each oven features a main burner that will bake and carbonize and grease, oil, debris or dirt on the work piece. A second stage afterburner in the exhaust eliminates any potentially hazardous fumes. After baking, the parts are transferred (via a material handling fixture) to the part is blasted while rotating to clean and prepare the surface for painting or reassembly. After blasting, the parts are again transferred to the shaker/tumbler cool down cabinet where the parts are rotated to remove shot or debris and a cooling fan removes any residual heat from the process.

Overview

Thermal cleaning systems are listed by the model number in the series:

The WVN Eliminator Oven uses a horizontal gas flame to quickly remove oil, grease, scale, rust and carbon without damaging hot spots. The patented, built‐in afterburners makes the WVN 36EN the cleanest in the country and you avoid costly chemical disposal problems.

Following use of the WVN Eliminator Oven we recommend the use of the WVN Shot Blaster to remove the ash. The shot is thrown onto the surface of the part using a horizontal rotor that provides an even blanket of shot for an efficient and consistent clean finish. The WVN Shot Blaster includes a WVN DC‐1 dust collector to contain the dust created in the blasting process.

The final stage recommended in the Thermal Cleaning System is the WVN Shaker Tumbler Cooler. In this stage the part is removed of any shot in the crevices and cools the part for handling. The machine rotates, oscillates and blows cool air over the part.
