The chamber kilns in the NW series combine the convincing quality benefits of the proven chamber kilns that are heated from five sides with a special feature. Charging these chamber kilns is much simpler, more ergonomic and also time-saving. With a drawer mechanism in the models up to 300 liters the floor can be easily pulled out. The larger models from 440 liters are designed as shuttle kilns with freely moving bogies. The optimal access in front of the kiln allows for simple and easy charging. 

These models are especially suitable for ceramic workshops, studios, clinics and schools. Most kilns are available from stock, even larger models can be delivered within a short time. 

The chamber kilns are available for maximum temperatures of 1300 °C or 1340 °C. If the kiln is often fired to its performance limits, we recommend our chamber kilns to 1340 °C.

ADDITIONAL EQUIPMENT

• Motorized exhaust air flap for models NW 150 -  NW 300/..
• Fan system for faster cooling with manual or automatic control
• Multi-zone control for optimal temperature uniformity in the work space
• Over-temperature limiter with adjustable cutout temperature as temperature limiter to protect the furnace and load
• Process control and documentation via VCD software package for monitoring, documentation and control 

Equipment:

 

• Ergonomic loading from three sides
• Heating elements on support tubes ensure free heat radiation
• Heating from five sides and a special arrangement of the heating elements provide for optimal temperature uniformity
• Scope of delivery includes SiC floor plates to protect the floor heating and provide for safe stacking of the kiln furniture
• Door cover made from structured stainless steel
• Semi-automatic air inlet flap that closes automatically after the drying phase in the firing program for chamber kilns up to 300 liters
• Motorized exhaust air flap in the middle of the kiln roof for optimal ventilation of the kiln with chamber kilns from 440 liters
