Vacuum oven is a box-type drying equipment that dries dry materials under negative pressure conditions. Its working principle is to use a vacuum pump to extract air and moisture, forming a vacuum state in the working room, lowering the boiling point of water, and speeding up drying.
Vacuum system
The door and the inner tank are sealed by silicone rubber strips. There is an air extraction hole at the rear of the working room, which is connected to the vacuum pump, pressure sensor, air inlet solenoid valve, vacuum pressure port on the panel and manual regulating valve at the rear base through pipelines.
The pressure sensor signal is sent to the smart instrument to display the absolute air pressure in the box. The vacuum pressure hole is used for pressure measurement and sampling. Before stopping the machine and opening the door, the air inlet solenoid valve must be opened to inlet air to balance the air pressure inside and outside the box before the door can be opened.
Protection System
1. The PID microcomputer automatic temperature controller used by our company can alarm the over-temperature problem of the machine studio and stop the power output by setting the internal upper and lower temperature limits to protect the products in the machine from over-temperature. and cause unnecessary losses.
2. Over-temperature protection system: When the temperature is out of control due to external forces, this system will automatically stop heating and power supply when it exceeds the set temperature by 10 degrees, thereby protecting the safety of your products and machines.
3. Overload protection system: When the power of the whole machine exceeds the normal power due to excessive external voltage or other reasons, this system will automatically cut off the power to protect the industrial control components of the whole machine from damage.
1.Integrated with incubator and shaker to save space and cost with tempered glass window.
2.ABS shell, stainless steel chamber.
3.Big LCD display showing temperature and shaking velocity.
4.With easy operations of storage function of working parameters.
5.Auto-recovery after power interruption as originally programmed.
6.Auto-stop protection to keep sample safe when the door is opened. Strong air spring rod with easy opening and closing.
