IntroductionFeaturesTechnical ParametersInquiryCustomer Case

Application: This vertical fluidized bed CVD system is specially designed for CVD experiments on powder surface deposition.

features

Vertical openable structure. The double-layer shell is a vertically openable structure, making it easy to pick up and place the furnace tube. It is equipped with an air cooling system to keep the temperature of the furnace shell within a safe range.
Multi-stage intelligent PID program temperature control. The temperature control system adopts PID method, and multiple "time-temperature curves" can be set at will, and 30 steps can be programmed.
Excellent dynamic sealing system. Stainless steel metal flange, with valves and related interfaces, easy to disassemble and assemble, can be vacuumed, and can connect two air sources to slightly positive pressure at the same time

Flange	Stainless steel vacuum flange, easy to disassemble
Sealing system	The furnace tube and flange are sealed by O-ring extrusion, which is easy to remove, can be removed repeatedly, and has good air tightness.
fluidized area	1. The reaction gas passes through the reaction zone evenly 2. The solid particles are suspended in the heating zone by the introduced gas. 3. The furnace body is designed to be open. When the experiment is completed, the furnace body can be opened, the quartz tube taken out, and the reacted particles taken out. Note: When gas is introduced to suspend sample particles, the particles may pass through the heating zone because the gas flow is too large. Therefore, the gas flow must be adjusted according to the size of the particles during the experiment.
