Product Details

Dual Heating Zone 1100°C Split Tube Furnace with Optional Tube (Dia 50, 85 mm) & Flange

TMAX-DSP1100-HP is a UL certifiable compact two heating zone split tube furnace with a max. working temperature of 1100°C. The furnace can adopt a pair of stainless steel vacuum sealing flanges. The furnace has two 8" L heating zone , which can provide 200 mm long constant temperature zone. Built-in two precision temperature controllers can provide up to 30 segments of heating and cooling steps with +/- 1°C accuracy.

Product Dimensions (mm)




AC 208-240V Single Phase, 50/60 Hz

Temperature range

100~1000° C (Continuous); 1100 C (<1 hour) 

Max. Heating Rate

<= 20° C /min

Heating Zone length

1.     Two zones: each zone length 8" (200 mm)

2.     Total 16" (400 mm) heating zone

Constant Temp. Zone

1.     150mm (+/-1°C) for each heating zone

2.     A longer constant temperature zone ( about 250mm ) can be created by setting both zones at the same temperature 

Temperature Controllers

1.     2 certified digital controllers with 30 programmable segments for precise control of heating rate, cooling rate and dwell time.

2.     Built in PID Auto-Tune function with overheating & broken thermocouple protection.

3.     Over temperature protection and alarm allows for operation without attendant(s).

4.     +/- 1 ºC temperature accuracy.

5.     Two K-type thermocouples (one for each zone).

6.     RS485 Communications Port.

Temperature Accuracy

+/- 1° C

Heating Element

Fe-Cr-Al Alloy doped by Mo

Vacuum Flange & Fitting Ports

1.     One pair of SS 304 vacuum flange with double high-temperature silicone O-rings are Included

2.     One Vacuum pressure gauge is installed, one digital vacuum gauge is available upon request at extra cost

3.     The flange set has two 1/4'' Bard fittings, two needle valve, one set of KF25 quick clamp, one blank flange fitting, 1/4'' tube feedthrough port (for 1/4" O.D thermocouple insert) and a KF25 vacuum port.

4.     Vacuum level can reach 10^-2 torr by quality mechanical vacuum pump and 10^-5 torr by molecular pump

Application Notes

1.     Tube furnaces with quartz tubes are designed for using under vacuum and low pressure < 0.2 bars / 3 psi / 0.02 MPa.Vacuum pressure may only be safely used up to 1000°C. The flow rate for gasses should be limited to < 200 SCCM (or 200 ml/min) for reducing thermal shocks to the tube.

2.     Attention: A two-stage pressure regulator must be installed on a gas cylinder to limit the pressure to below 3 PSI for safe operation.


One year limited warranty with lifetime support.
