Model | HT-1800-80 |
Working Temperature | 800 -1750ºC continuous Max: 1800ºC < 2 hour |
Heating Elements | Kathal Super-1800 MoSi2 heating elements - 270mm L ( 4 pcs ) made in Sweden |
Furnace Structure of bench top tubular furnace | Double-layer steel casing with air cooling. Two cooling fan inside to keep case temperature < 60oC. High purity Alumina refractory chamber with max energy saving. Alumina tube, vacuum flange, gauge & valves are included. Such a compact space-saving furnace can be placed on the 600mm x 600mm mobile cart (available in the optional parts list below). |
Power Consumption | Max. 6KW |
Input Voltage | Single Phase, 220V AC, 50/60 Hz (30A breaker required) |
Max. Heating / Cooling Rate | 10ºC / min |
Heating Zone | 120 mm |
Constant Temperature Zone | 80mm within ± 5ºC at 1500oC |
Temperature Controller | PID automatic control via SCR (Silicon Controlled Rectifier) power control with phase angle fired, current limiting resistor. 30 programmable segments for precise control of heating rate, cooling rate, and dwell time. Please click here to learn why SCR is more accurate than SSC (Solid state relay). Built-in over-temperature alarm and protection allow for operation without an attendant. +/- 1 ºC temperature accuracy. RS485 Communication Port. Optional: The vacuum tubular furnace may be operated by a PC by installing a control module. Please order an MTS-02 control module at extra cost. If you order the PC control module together with the furnace, we will install and test it before shipping. We recommend you to order a computer (laptop) from us to avoid software installation problems. |
Tube Materials | High purity Al2O3 ceramic, Purity > 99.9% |
Processing Tube | Premier Grade alumina tube made in USA. 70 mm (I.D) x 80 mm (O.D) x 800 mm length. Four fiberous ceramic tube blocks are included for blocking heat radiation from inside tube. (Ceramic blocks must be fully inserted into the furnace chamber before heating). For 80mm tubes, it is recommended that customers purchase two pairs of tube support to prevent tube from bending under high temperature. |
Sealing Flanges | One pair sealing flange with double silicone high-temperature O-ring is included. Two SS needle valves and one dial vacuum gauge are installed with a flange for immediate use. Vacuum pressure can reach 50 mTorr by a quality mechanical vacuum pump and 10^-5 torr by turbo molecular pump. |
Fitting Ports | Standard 1/4‘’ Barbed fittings with needle valves. For supplying high-pressure gas, you may replace the standard barbed hose fitting with the 304SS 1/4" Tube Fitting. Optional: In order to increase the throughput and achieve high vacuum, you may replace the standard barbed hose fitting with the KF25 adapter, please order the underlined again. Optional: You may also consider using the parts in below to increase the vacuum efficiency Please click here to order a digital vacuum gauge for precision vacuum control up to 10-4 torr. You may click here to order flow meter and install in tube flange. KF25 Stainless steel Bellows KF25 Quick Clamps You may order a pressure control module to keep the chamber at constant pressure |
Vacuum Level | Limited by vacuum pump 50 mtorr can be achieved by a mechanical pump 10^-5 torr can be reached by molecular pump The vacuum pump is not included, please order separately. |

Net Weight | 150Kg |
Shipping Dimensions | 38"x 38"x 38" |
Shipping Weight | 375 lbs |
Warranty | One year limited manufacture warranty with life time support (consumable parts such as furnace liner, processing tubes, and O-rings are not covered by the warranty, please order replacements at related products below). |
Application Notes | In order to obtain accurate temperature inside tube furnace, you need to perform a temperature calibration before use, please click here to learn how. How to set up ceramic tube and vacuum flange for Horizontal Tubular furnace Proper placement of tube blocks The high temperature tubular furnaces with alumina tube are designed for use under vacuum and low pressure < 0.02 MPa Attention: A pressure regulator must be installed on your input gas tank and have the output gas pressure set below 3 PSI at all times after opening the gas tank with the gas maintained in a continuous flowing condition. Gas build-up with pressure levels exceeding over 3 PSI may cause irreversible damage to the furnace chamber. Never heat the 1800 tubular furnace while the gas release valve is closed and a positive pressure condition exists within the furnace chamber. The pressure gauge must be used to closely monitor the chamber condition at all times during the heating process; please open the gas release valve immediately once the chamber pressure has reached over 3 PSI to prevent unforeseeable damages. The flow rate for gases should be limited to < 200 SCCM (or 200ml/min) Vacuum pressures may only be safely used up to 1500°C |
