When equipped with various equipment packages, the tube furnace product lines can be adapted for operation with nonflammable or flammable gasses or for vacuum operation.
Gas Supply System 1 for non-flammable protective or reactive gases Not gastight, no vacuum operation
This package represents a basic version sufficient for many applications, for operation with non-flammable protective or reactive gasses. The standard working tube made of ceramic C 530 delivered with the furnace can still be used.
-
Available for tube furnaces RD, R, RT, RSH and RSV
-
Standard working tube can be used
-
2 plugs made of porous, non-classified ceramic fiber incl. protective gas connections
-
Gas supply system for nonflammable protective gas (Ar, N2, forming gas, others on request) with shutoff valve and flow meter with control valve, optionally with magnetic valve. One gas intake pressure at 300 mbar to be provided by customer.
Gas Supply System 2 for non-flammable protective or reactive gases/vacuum operation
For increased atmospheric purity requirements in the working tube, we recommend this gas supply system. The system can also be equipped for vacuum operation.
-
Available for tube furnaces R, RSH, RSV, RSRB, RSRC, RHTC, RHTH, RHTV
-
Gas supply system for nonflammable protective gas (Ar, N2, forming gas, others on request) with shutoff valve and flow meter with control valve, optionally with magnetic valve. One gas intake pressure at 300 mbar to be provided by customer.
-
Additional equipment for static tube furnaces:
-
Longer, gas tight working tube of ceramic C 610 for furnaces to 1300 °C or of C 799 for temperatures above 1300 °C
-
2 vacuum-tight, water-cooled stainless steel flanges with fittings on the outlet side (cooling water supply with NW9 hose connector to be provided by the customer)
-
Mounting system on furnace for the flanges
-
Additional equipment for RSRC models (continuous operation): charging system
-
Additional Equipment for RSRB models: gas-tight rotarylead-outs on gas inlet and outlet, gas cooler and gas outlet valve
Vacuum Operation
-
Vacuum package for evacuation of the working tube, consisting of connector for the gas outlet, ball valve, manometer, manually operated rotary vane vacuum pump with corrugated stainless steel hose connected to the gas outlet, max. attainable end pressure in working tube depending on pump type
-
Pumps for max. final pressure of up to 10-5 mbar (models RSRB/RSRC up to 10‑2 mbar) on request
-
The decrease in strength of the working tube at high temperatures limits the maximum operating temperature under vacuum
Gas Supply System 4 for hydrogen, fully-automatic, unattended operation
Adding gas supply system 4 to the tube furnace allows operation under a hydrogen atmosphere. During hydrogen operation, a safety pressure of approx. 30 mbar is ensured in the working tube. Surplus hydrogen is burnt off in an exhaust gas torch. With extended safety logic and an integrated nitrogen purge container, the system can be used for fully-automatic, unattended operation. Equipped with a Safety-PLC control system, pre-purging, hydrogen inlet, operation, fault monitoring and purging at the end of the process are carried out automatically. In case of default, the tube is immediately purged with nitrogen and the system is automatically switched to a safe status.
-
Available for tube furnaces RSH, RSV, RSRC, RHTH and RHTV
-
Safety system for operation with flammable gases including monitoring of torch function and overpressure
-
Extended safety control system with emergency tube purging in case of default
-
Emergency purge container
-
Safety-PLC control system with touchpanel for data input
-
Exhaust gas torch
-
Pressure switch for monitoring the safety pressure
-
Gas supply system for H2 and N2. Volume adjustment is carried out by hand (the customer provides an H2 supply at 1 bar, an N2 supply at 10 bar, an O2 supply at 6-8 bar and a propan supply at 300 mbar)
