Nabertherm Gas Heated Chamber Kiln NB300

Available

Product Description

Some firing processes or connecting conditions require a gas-fired chamber kiln. Fast heating times and unique firing results are strong reasons for using such equipment.

Equipped with powerful gas burners the chamber kilns NB 150 - NB 600 are suitable for creative applications. An automatic temperature regulation is included in the basic model. The controller starts controlling after the burner has been manually ignited by automatic switching the burner between high and low loads. The burners have been optimized to allow relatively precise control from 300 °C. Despite this, we still recommend drying the charge completely to avoid waste caused by rapid heating up in the lower temperature range. At the end of the program, the burners are automatically shut off.

High-performance, atmospheric burners for operating with liquid petroleum gas (connected pressure 1.5 bar/20 mbar or 50 mbar) or natural gas (connected pressure 20 mbar or 50 mbar)
Depending on the application, special positioning of the gas burners with flame guidance provides for optimal temperature uniformity
Manual set-up of burner power and atmosphere (oxidizing or reducing)
Gas fittings with flame control and safety valve in accordance with DVGW (German Technical and Scientific Association for Gas and Water)
Multi-layer, reduction-proof insulation with light-weight refractory bricks and high-quality back-up insulation result in low gas consumption
Rugged, self-supporting, vaulted arch construction
Environment-friendly, long-life powder-coating of housing
Dual shell housing
Dual shell door with long-live sealing
Door is adjustable
Exhaust hood
Base included in scope of delivery
Comfortable charging height with base of 760 mm (NB 150, NB 300) and 600 mm (NB 400, NB 600)
Defined application within the constraints of the operating instructions

CONTROLLER

Program Controller B400:

Easy and individual programming
5 programs can be stored
Delayed start time of the kiln (e.g. for using economy 7)
4 freely adjustable segments
Input of the set points in increments of 1°C and/or 1min.
Skip-button to bypass a segment while the program is running
Hold times may be extended while the program is running

Controller pre-set programs (B400 and C440):

Normal biscuit firing -> 900°c
Slow biscuit firing -> 900°c
Glaze firing -> 1050°c
Glaze firing -> 1150°c
Glaze firing -> 1250°c

There is an option to upgrade to the C440 controller. The C440 has the same functions as the B400 but the larger memory means you can store 10 programs with 20 segments each.
