WEIBER vacuum resistance furnace is widely used in the heat treatment of metallic material in coarse vacuum, in reducibility or protective atmosphere. It Can also be used for special heat treatment of materials such as carbon products in the development process of carbonation. It can heat materials, typically metals, to very high temperatures and carry out processes such as brazing, sintering and heat treatmentwith high consistency and low contamination. In a vacuum furnace the product in the furnace is surrounded by a vacuum. The absence of air or other gases prevents heat transfer with the product through convection and removes a source of contamination.

Weiber designs and manufactures advanced vacuum furnaces with the highest quality standards in a wide range of geometries and dimensions. The Furnace are designed to meet temperature & vacuum atmosphere requirements.

Uniform temperatures in the range 11001500C (20002800F)
Low contamination of the product by carbon, oxygen and other gases
Quick cooling (quenching) of product.
The temperature control unit consists micro-processor based PID controller cum indicator. benefits of using PID controller:

Processing speed is high
Provides flexibility to alter the system by changing software.
Compact in size.
Operation and maintenance easier.
Maintain precise values

Over temperature limiter.
Programmable Vacuum automatically control the vacuum on/off according to the user-defined value of temperature (vacuum start & stop temperature) and time (vacuum holding time).
PCRC Sheet Body- Powder coated steel body assures corrosion resistant furnace and allows working of chamber at high temperature applications.
Digital Output Target and Performance Output of the furnace operations are in digital format(digits) giving precise reading.
Precise Control of Environmental Parameters-The set/ programmable parameters of thefurnace are precise or have less deviation from original value, thus ensuring correct measurement.

WEIBER batch ovens are used for a wide variety of heat processes including drying, curing, aging, annealing, stress relieving, bonding, tempering, preheating, and forming. Batch ovens are essentially heated boxes with insulated doors that process products one at a time or in groups. These are for applications where load size or production volumes vary substantially. Batch oven have been designed to accommodate a variety of load sizes and production volumes. It accommodates horizontal air flow virtually from Front-to-back without restricting air passage to provide rapid heating with high thermal transfer to the chamber contents and high uniformity within the chamber. It also helps to eliminate water or moisture accumulated during the pre-treatment washing process.

Temperature range upto 8500F(4550c)
Microprocessor based temperature control.(HMI+PLC as an option)
Uses horizontal recirculating airflow to ensure uniform temperatures throughout the oven.
