SNO, SNZ chamber furnaces

 SNO, SNZ series chamber furnaces for heat treatment under air or protective atmosphereat a temperature of up to 1250 °C.

The furnacesare used for annealing, baking,quenching, normalizing and meltingof metal products. They can be used as multi-purpose chamber furnaces for heat treatment of ceramics, porcelain and other materials.The furnaces can beequipped bylift of wing door, pull-out hearth, fans and screens. Additionally the fire-proof bottom plates can be provided.

Working chambers of SNO and SNZ furnaces are made of modern high-performance fireproof materials.

The spiral heating elements aremounted on theceramic tubes along the side walls.Additional heating elementscan be mounted on furnace hearth, back wall and cover.

Control system is based on a modern MBU series controller(made by MIUS). Control system continously diagnoses the power circuits, protecting the heating spirals from overheating, blowing-out and preventingfrom concequences of breakage and short-circuits.

Thefurnaces are certificated and complied with terms of reference 3442.009.24662585-04 (statement of compliance#ROSS RU.42.00040 26.08.2011).
