The HT-1200X-H8 is a high-performance horizontal chamber furnace featuring a quartz chamber with dimensions of Ø7.5" inner diameter (ID) and 13.4" length (L). Equipped with a hermetically sealed chamber, it enables precise heat treatment processes under controlled atmospheric environments or vacuum conditions, supporting a maximum operating temperature of up to 1100°C.
Its airtight design ensures excellent gas tightness, effectively preventing external air infiltration and maintaining stable internal conditions—ideal for applications requiring strict atmosphere control and contamination-free heat treatment. This furnace combines reliable temperature uniformity with versatile environmental adaptability, catering to diverse industrial and laboratory heating needs.
SPECIFICATIONS
Power | Voltage: Single-phase 208 - 240 VAC / 50/60Hz, (25 A breaker installed) 3 KW max. Note: Power cable included but without the plug. Please install a plug by your own or choose a plug according to your country or your lab requirements |
| <1100°C under ambient pressure <1000°C under vacuum GE214 quartz tube is available for 1150oC working temperature at extra cost. |
Heating Rate | <20°C/ min Recommended: 10°C/ min |
Heating Elements | Ni-Cr-Al resistance wire |
Quartz Tube & Effective Heating | Tube size: Ø200×Ø190×H425 mm Max. loading 40Kg Heating area Ø240×H245 mm |
Vacuum Flange | Stainless steel vacuum flange with dual high-temperature silicone O-rings with water cooling jacket One 1/4 gas inlet and one gas outlet with needle valves. One bored Al2O3 foam refractory block (190Dia x 50mm) is provided K25 port is built-in for connecting to the vacuum pump Mechanical Vacuum Gauge (included as standard accessory), which ranges from -0.1 to 0.15Mpa |
Water Cooling | A water-cooling jacket has been built inside the flange to protect the vacuum sealing assembly from melting at over 200°C. 16L/min water flow required. |
Temperature Controller | NRTL certified digital temperature controller is included Proportional–integral–derivative control (PID control) and auto-tune function 30 segments programmed with ramping, cooling, and dwelling steps Built-in over-temperature alarm and thermocouple failure alarm +/- 1 ºC temperature control accuracy THE Default DB9 PC communication port included for connecting to PC Eurotherm Temperature Controller is available at the extra cost with +/-0.1°C accuracy |
Options | Digital Pressure Gauge (optional) A gas-type independent(above 10mbar) digital vacuum gauge with a wide range between 3.8 x 10-5 to 1125 Torr. You may choose a gas mixer to deliver multiple gasses with control over gas composition and flow rate The furnace can be modified into a faster heating and cooling furnace |
| Vacuum Level is dependent on the vacuum pump used, connected pipe, interior refractory block's materials, etc. By using KFD25, stainless steel pipe, STA's two-stage mechanical pump, and KF25 Ball valve, the furnace can achieve vacuum levels below: 10-2 torr via mechanical pump within 30 minutes without thermal Block 10-5 torr via turbo-pump within 30 minutes with the Quartz Thermal Block at 900C Optional: The vacuum pump and pipe are not included, For achieving a higher vacuum level, a Turbopump Station is necessary. Spare sealing O-ring is available at extra cost KF25 Right-Angle Valve for quick connection to KF25 Bellows |

Net Weight | 70 kg |
Shipping Weight | 200 lbs |
Shipping Volume | 45"(L) x 28"(W) x 35"(H) |
| One-year limited warranty with lifetime support (consumable parts such as processing tubes, and O-rings are not covered by the warranty, please order replacements at related products below.). ATTENTION: Any damages caused by the use of corrosive and acidic gasses are not under the coverage of STA One Year Limited Warranty. |
Compliance | CE Certified |
Warning
| Tube furnaces with quartz tubes are designed for use under vacuum and at low-pressure < 0.2 bars Attention: A two-stage pressure regulator must be installed on the gas cylinder to limit the pressure to below 3 PSI for safe operation. A maximum temperature of 1000°C should be imposed on all quartz tube furnaces to avoid the quartz tubes undergoing deformations under vacuum. The flow rate for gasses should be limited to < 200 SCCM for reducing thermal shocks |
