Advanced Hot-air Circulation Sterilization Tunnel for
I. Technical Parameters
1. Range of temperature adjustment: room temperature: 10°C--300°C
2. Temperature fluctuation: ±1°C
3. Blast motor power: 40W
4. Heating furnace wire power: 1.6KW
5. Rated voltage: 220V
6. Dimension of working room: 450×450×450 (mm) can be customized
II. Basic Functions and Configuration
1. The outer wall of equipment uses 304-2B1.5 stainless steel board
and the inner wall uses 304-2B 1.5mm stainless steel board. It
presents angle like R all around. Do polished both outer and inner
wall and it complies with a standard of GMP.
2. The heating element uses 304 stainless steel tubular heaters and
distributes in the box. So the hot air convention makes the each
point’s temperature uniformly under internal circulation fan’s
3. It uses horizontal laminar flow wind in the box. (The top sends
air and the side air comes back.) Send the internal hot air to the
box through high temperature high efficiency filter’s side under
the fan’s effect.
4. Convection wall has adjustable air board and let the each
point’s airflow uniformly inside the box.
5. The top of oven has air inlet and air outlet and the air inlet
has cooling fan. It sends the level of ten thousand airs to box
through high efficiency filter and the materials will force cooling
rapidly under the fan’s pressure. The air outlet has high
efficiency filter and air door.
6. The oven door uses interlock device. When a side door opened,
the other side door can not be opened and the indicator light shows
the opening condition. Doorknob uses crankshaft to compact and heat
resisting silicone rubber will seal.
7. The box body has two gauges and reflects high efficiency
filter’s working condition intuitively.
8. Choose high-precision temperature control device and have
Programmable Logic Controller (PLC),HMI touch screen. It also has
temperature of the printer and record device graph of heating,
thermostats and cooling to easily backup and examine.
9. Oven design temperature range:Room temperature -300℃, Working
temperature≧260℃, Temperature control sensitivity±1℃, Temperature
uniformity in the box±2.5℃. The oven has verify hole, so it can
verify temperature uniformity on site.
