1500°C Atmosphere Controlled Rapid Heating Furnace (ACRHF) - RHF-1500S

Please email for lead time
Item Number: RHF1500S
Transported by LTL Freight (Truck)
RHF-1500S is a bench-top atmosphere-controlled rapid heating furnace ( ACRHF)  with a max working temperature of 1500oC.  The small furnace is designed for simulating a big kiln to find suitable sintering processing, and it is excellent for making single crystal cathode powders for battery materials.


Furnace Features

  • Two heating zones with ceramic rollers in the middle to produce rapid heating
  • Heating elements are made of SiC rods with max. 1500oC working temperature
  • The heating module is placed inside a vacuum chamber for atmosphere control from oxygen to inert gases.
  • 400 mm long heating zone with 200mm constant temperature zone within +/- 2ºC
  • Dual programmable temperature controllers provide +/-1ºC accuracy
  • Two flowmeters are installed for gas flow control
  • AC 208-240V,  single-phase, 50/60 Hz
  • 12 KW max   ( 30A breaker and plug required )
  • 10-foot power cable included but without plug  
  Heating chamber

  • SiC rod as heating elements
  • Heating Zone: Two heating zones with a total  dimension of L400 x W150 x H89 mm  ( 53L capacity)
  • Constant temperature zone:  200 mm with +/- 3ºC
  • Almina ceramic rods are in the middle of the heating chamber to hold the multi-crucibles
  • Fiberus alumina is used as thermal insulation
  • Max. working temperature:   1500°C max (< 60 minutes )    and  1400°C (continuous )
  • Max heating rate:   50 ºC/s
    Vacuum chamber
  • The heating module is placed into a stainless steel vacuum chamber with
    • KF 25 vacuum port
    • Dail vacuum gauge
    • Gas inlet and outlet port ( 1/4)
  • Two hinged types doors for loading and unloading samples

Temperature Control


  • Two temperature controllers for controlling two zones independently via SCR
  • PID automatic control with up to 30 programmable segments for precise control of heating rate, cooling rate, and dwell time.
  • Over-temperature protection and alarm allow for operation without attendant(s).
  • Two S-type thermal couples are included
  • ± 1 ºC temperature accuracy for dwelling.
  • RS485 Communications Port.
  • PC Control:  
    • An MTS-02 control module is included for PC control on this furnace.
    • We recommend ordering a computer (laptop) from us to avoid software installation problems as we will perform installation and testing before shipping. For more information please click here

Vacuum Level and
Gas compatible

  •  Limited by the vacuum pump
    • 10^-2 torr can be achieved by the mechanical pump
    • 10^-4 torr can be reached by molecular pump
  • The pump is not included. (Please click the picture left to order )
  • The furnace is comparable to oxygen and inert gases ( not for flammable gas )
  • For use with H2 gas,  you must get a permit from MTI, and the furnace must be modified

Crucibles (optional)

  •  Two Alumina Boats / Saggar  (400ml) can fit into the furnace and sinter 1 kg NMC ( Click Pic 1 to order)
  •  8 round crucibles ( 50 mm Dia ) can fit into the furnace for multi-composition materials.(Click Pic. 2 to order )
