Heating and drying ovens VTU

Heating and drying ovens VTU are available in 7 sizes with a comprehensive range of accessories, e.g. loading trolleys, temperature controller etc. They can be used globally for heating and drying processes in the production and research.

Process characteristics

• Short process duration due to high volume of circulating air.
• Short recovery time due to automatic switch-off of heating and circulating air fan when door is opened.
• Homogenous temperature distribution, thanks to directed air ductwork.
• Reproducible production results by high quality standards.
• Application-orientated air ductwork, both horizontal (standard) and vertical (optional).

Production characteristics

• Economical and environmentally friendly, thanks to the enhanced thermal insulation.
• Optimum thermal separation of inner and outer casing.
• Minimum loss of energy and effective operator protection when coating, thanks to the heating and circulating fan being switched off.

A high degree of safety, thanks to

• Low external wall temperatures
• Safety temperature limiter (protects units)
• “Cold” heating connection
• Service and maintenance friendly
• All heating and drying ovens naturally comply with EMC guidelines.

Standard Version

• Nominal temperatures 250 / 300 / 350 / 400°C
• Outer casing made of galvanized sheet steel, coated with RAL shade 9002 (grey-white).
• Corrosion-resistant inner casing made of aluminised sheet steel.
• Low external wall temperature and minimal loss of energy due to highquality, generously dimensioned thermal insulation.
• Grid rails in working chamber, facilitating height adjustment of wire-mesh shelves and grates.

• The temperature-resistant door gasket is easily exchanged.
• Door of walk-in units can be opened from inside (from model size 75/100).
• Tubular heating elements made of stainless steel.
• Safety temperature limiter (protects unit).
• Microprocessor-based temperature control with solid state relays ensure minimal control fluctuations.

• Control panel with additional display and control elements which can be upgraded, thanks to its modular construction.
• Exemplary air ducting system which enables an incredibly even temperature distribution to be achieved, even with a fresh air supply. The air in the working chamber is mixed in this system with fresh air sucked in via a heating register, mixed by the circulating air fan and conveyed once more to the working chamber.
•  Air exchange via air intake and exhaust flanges. Air intake flanges are closed by delivery.
