VTUW Series

Explosion-proof heating ovens and drying ovens, series VTUW, in GMP-/FDA-suitable design

The amount of combustible solvents is nearly unlimited in this oven. It can be installed in the explosive zones 1 and 2, because of permanent monitoring of the discharge air flows. This eliminates the danger of an explosion. The VTUW is suitable for the temperature classes T1, T2, T3, T4 in the explosion groups IIA and IIB. For this oven, warm water or vapour of other processes can be used as a heating medium.

Working chamber volume 700 - 3125 liters Product Image (Main)
Temperature 20 – 200 °C
Temperature classes T1, T2, T3, T4
Installation Zone 1 and 2

VTUW Series

During many heat treatment processes, flammable substances (solvents, gases etc.) are emitted that can result in an explosive mixture when combined with air. In order to prevent this mixture from causing an explosion, special precautions must be taken.

The solution

Vötsch Industrietechnik has developed special concepts for a variety of requirements to prevent risks of explosion. For critical conditions as they occur, e. g. in the chemical, pharmaceutical and electronics industry, the heating and drying ovens of the VTUW series have been designed to fulfil considerably higher requirements than conventional dryers for

coating materials. Special measures of protection against explosion prevent the dangerous

explosive atmosphere from igniting and ensure safe and reliable heat treatment processes.

The VTUW series is a combination of safety, reliability and sophisticated functionality. A well thought out concept, high-quality materials and components plus accurate production ensure fail-safe, reliable heating and drying ovens.

For heat treatment of material used by the aerospace & defence industries, Vötsch Industrietechnik offers the appropriate ovens which fulfil the requirements of the standard AMS 2750 D.

Safe

The volume of flammable substances that can be introduced is virtually unlimited. The heating

and drying ovens comply with category 2 devices and can thus be installed in zones 1 and 2 of areas where there is a danger of explosion.

Flexible

Design in compliance with device group ll, i. e. suitable for solvents of temperature classes T1, T2, T3, T4 and explosion groups llA and llB.

Economic

Warm water or steam emitted from processes can be introduced as a heating medium.

Low energy consumption and short process times thanks to circulating air with low fresh air

volume.

Precise

High constancy of temperature in the entire working chamber.

CE-compliant as per 94/9/EU

Installation

For installing in explosive zones, all components are explosion-proof according to the respective zone. Fresh air required for safe and reliable operation must be supplied

from a neutral zone

Temperature conditioning devices

Fresh air grid

Exhaust air fan

Door window

Shelves and grids

Charging trolleys

Flow control valves
