Combi Chamber Furnaces up to 1400 /掳C: Top Choice in Malaysia, Selangor, KL Obsnap Instruments Sdn. Bhd.

Description

The combi chamber furnaces N 100 DB - N 1500/14 DB are specially developed for debinding and sintering in one process. The furnaces have a fresh air supply providing for dilution of the exhaust gases produced during debinding, for safe prevention of an inflammable atmosphere in the furnace chamber. The standard version of the furnaces is equipped with the debinding package DB100. This debinding package provides for an injection of fresh air for atmosphere dilution which means that the furnace works under overpressure during debinding.

As a professional solution for production furnaces, we recommend the debinding package DB200. The furnace then has a warm fresh-air injection with variable speed through distribution tubes in the furnace chamber. The exhaust fan operates also with a variable fan speed. The PLC automatically regulates a negative pressure inside the furnace chamber.

Tmax 1280 °C, 1340 °C or 1400 °C
Dual shell ventilated housing made of textured stainless steel sheets for low surface temperature and high stability
Five-sided heating from all four sides and from the floor for a good temperature uniformity
Heating elements on support tubes provide for free heat radiation and long service life
Multi-layer insulation consisting of lightweight refractory bricks backed by special insulation
Exclusive use of insulation materials without categorization according to EC Regulation No 1272/2008 (CLP). This explicitly means that alumino silicate wool, also known as “refractory ceramic fiber” (RCF), which is classified and possibly carcinogenic, is not used.
Self-supporting and long-life ceiling construction, with bricks laid in arched construction
Bottom heating protected by SiC tiles with an even stacking base
Motorized exhaust air flap on the furnace roof
Debinding package DB50 for chamber furnace N 100..
From model N 200: debinding package DB100 with fresh-air fan, air-preheater and controls
Over-temperature limiter with adjustable cutout temperature as temperature limiter to protect the furnace and load
Defined application within the constraints of the operating instructions
Controller with touch operation P570 (50 programs with each 40 segments) for models N 100..
From model N 200: HiProSystems H1700, including Siemens PLC control and 7” touch panel as operator interface
