Chamber kilns Nabertherm

Chamber Kilns, Heated from Five Sides

Chamber kiln N 300	Chamber kiln N 440

Heating from five sides and a special arrangement of the the heating elements ensure optimal temperature uniformity

Semi-automatic air inlet flap for residual drying in chamber kilns up to 300 liters. The flap closes automatically at a set temperature and does not have to be closed manually after the drying phase.

First-class craftsmanship, professional design, long service life and excellent temperature uniformity – chamber kilns from 100 liters up to 2200 liters round off the range of kilns for professionals. These kilns have proven their worth for many years, firing porcelain and stoneware and annealing glass, even when tightly stacked and at high working temperatures. You will find these chamber kilns in ceramic workshops, studios, clinics, schools and in private homes. They are recommended for frequent firing, when the kilns are tightly stacked and when excellent temperature uniformity is needed.

A kiln should not be operated permanently to its performance limits. If the kiln is often fired to its performance limits, we recommend our chamber kilns to 1340 °C. Most chamber kilns are available from stock.

Chamber Kilns, Heated from Three Sides

Chamber kiln N 280 E	Chamber kiln N 140 E

Chamber kiln N 500 E

Three-sided heating with heating elements protected in grooves (N 140 E - N 280 E)

Three-sided heating with heating elements on support tubes (N 500 E)

Due to their good price-performance ratio, the Nabertherm chamber kilns heated from three sides are suitable for use in schools, kindergartens or occupational therapy. The heating elements are protected in grooves. For an intensive, professional use, we recommend our five-side heated chamber kilns.

The dual-shell, back-ventilated housing keeps the housing temperature low. A semi-automatic air inlet flap is included with standard scope of delivery. After the drying phase in the heating program, the flap closes automatically at a chosen temperature. No base flap has to be closed manually. The controller can be removed from the door bracket for convenient operation.

Standard design N 140 E - N 280 E

• Heating elements protected in grooves
• Heating from three sides (both sides and floor)
• Scope of delivery includes 3 ceramic supports and lower shelf to protect the bottom insulation and for safe stacking of the kiln furniture
• Base included in scope of delivery
• Defined application within the constraints of the operating instructions

Standard design N 500 E

• Freely radiating heating elements on support tubes
• Heating from three sides (both sides and floor)
• Scope of delivery includes SiC floor plate for even stacking of the kiln furniture
• Motor-driven exhaust air flap in the middle of the kiln roof for optimal ventilation of the kiln
• Defined application within the constraints of the operating instructions

Chamber Kilns, Heated from Two Sides

Chamber kilns N 70 E with base as an accessory	Chamber kiln N 40 E as a tabletop model

Designed as chamber kilns with wide-opening door these models can be easily and clearly loaded. The appealing design and attractive price are convincing arguments for this kiln series. The heating elements are protected in grooves.

The kilns can be used for ceramics and glass or porcelain painting or also for simple fusing works. Most chamber kilns are available from stock. The infinitely adjustable air inlet opening in the door and the exhaust air opening in the roof ensure good ventilation inside the kiln and reduce cooling times.

Standard design

• Heating elements protected in grooves
• Heating from both sides
• Designed as a tabletop model, base available as an accessory
• Infinitely adjustable fresh air inlet
• Scope of delivery includes an option for connecting an exhaust air pipe (80 mm diameter)
• Dual shell housing for low outer temperatures
• Defined application within the constraints of the operating instructions
