Instrument Introduction:

By equipping different accessory packages,RSTheRHTC, RHTHandRHTVThe series of kilns can perform non combustible, combustible, or vacuum operations.

Key Features:

Gas distribution bag1: Used for simple protective gas operation(Non vacuum operation)
This accessory kit can meet the basic needs of various non combustible operations. Standard working pipes supplied with the kiln (made of materials)C 530The product can continue to be used. Standard work tube can be used2A ceramic fiber end plug with a protective gas joint and a non combustible protective gas distribution system(Ar,N2,mixed gas)Flow meter with shut-off valve and regulating valve (volumetric flow rate)50 -500 l/h）The pipeline has been connected（300 mbaAdditional configuration of second or third non combustible gas expansion gas distribution system gas cylinder pressure reducers for automatic gas supply systems (with additional solenoid valves on the distribution plate), connected and closed through additional programmable functions of the controller (such asP 330）//orThe import pressure is the responsibility of the customer

gas supply system2Used for working in non flammable protective atmosphere and vacuum atmosphere

If the purity of the gas inside the tube needs to be improved, we recommend using this gas distribution bag. The standard working tube is made of airtight tube (made of material)C 610orC 799Replace the product. The scope of supply includes not only extended working pipes, but also airtight flanges and corresponding fixing devices. The system can also be used for vacuum operation to extend the airtight tube, made of materialsC 610(Used for temperatures below1300 °CThe kiln orC 799(Used for temperatures above1300 °CMade in kilns
2A vacuum sealed stainless steel water-cooled flange installed on the outlet side (through a water pipe interface)NW9The cooling water supply is the responsibility of the customer
fixture

Used to fix flanges to non combustible protective gas distribution systems in kilns(Ar,N2,mixed gas)Flow meter with shut-off valve and regulating valve (volumetric flow rate)50 - 500 l/h）,Exhaust valve, pipeline connected（300 mbarThe import pressure is the responsibility of the customer
Additional configuration
Use the second or third non combustible gas expansion gas distribution system gas cylinder pressure reducer for automatic gas supply systems (with additional solenoid valves on the gas distribution plate), which can be connected and closed through additional programmable functions of the controller (such asP 330）The end water-cooled flange with quick connect device is used for closed water circulation. The cooling device flange is equipped with a window inside, which can observe the condition of the material
vacuum operation
A vacuum system used to evacuate a working tube, consisting of the following components: exhaust plug1A single-stage rotary valve vacuum pump with a ball valve, pressure gauge, and manual operation (with a stainless steel bellows connected to the exhaust port). The maximum final pressure that can be achieved in the working pipe is10^-2 mbarOther final pressures reach10^-5mbarThe pump can be supplied on demand (see“vacuum pump”）

gas supply system3 Used for working in a hydrogen atmosphere and manually operating under the supervision of staff by installing a gas supply system3Tube furnaces can operate in a hydrogen atmosphere. When working in a hydrogen atmosphere, the safety overpressure control inside the working pipe is30 mbarabout. The excess hydrogen is burned by an exhaust combustion device. Before, after, and in the event of a malfunction during the process, operators need to manually complete the inerting of the working furnace. Safety techniques for working in a combustible gas atmosphere, including monitoring flame function and monitoring pipeline rupture using overpressure to extend airtight working pipes2A vacuum sealed water-cooled stainless steel flange (cooling water supply to be solved by the customer through water pipe joints)

gas supply system4 Used for working in a hydrogen atmosphere, fully automatic,
No need for manual supervision
By using the built-in nitrogen emergency flushing container to enhance safety performance, the kiln can operate fully automatically without supervision. Equipment safetyPLCThe controller, pre flushing, hydrogen introduction, operation, fault monitoring, and flushing are all automatically performed at the end of the process. When a malfunction occurs, the working pipe will be immediately flushed with nitrogen and the equipment will automatically enter a safe state.

Additional safety control device, emergency flushing of work pipe and container in case of malfunction
Through securityPLCDevice control, touch screen for data input
system3 - 4Additional configurations
Simple safety technology is used for hydrogen introduction operations, only for temperatures above800 °Cthe situation
The working temperature is higher than800 °CYou can open the work tube at that time
Guide the flame onto the outlet of the work pipe
temperature below800Hydrogen cannot be introduced at ℃, the system is locked
RSSeries can be used
Expansion device for gas supply system, used for other non combustible gases
Gas cylinder pressure reducer, used for supplying gas to gas cylinders
Cooling platform, used for closed cooling water circulation
Vacuum system (can only be used for pre vacuuming during hydrogen operation)
PLCController (in gas supply system)4Internal standard configuration)
Gas supply implemented by programmable quality flow controller (only applicable for use)PLCFurnace type of controller

vacuum pump
We offer various vacuum pumps based on the final pressure (see also below)“vacuum pump”）：
One stage rotary valve vacuum pump, with a final pressure of approximately20 mbar.
A two-stage rotary valve vacuum pump with a final pressure of approximately10^-2mbar.
PT70 DryThe final pressure of the pump workstation (membrane pump with rear mounted turbo molecular pump) can reach10^-5 mbar.
Hint:
To protect the pump, only the cold vacuum method can be used. Due to the fact that high temperatures can reduce the strength of the working tube, it is necessary to comply with the maximum working temperature under vacuum conditions (see“Control mode and work management”）.
