Vacuum Drying Oven — Digital Vacuum Display and Control
Vacuum Drying Test Oven
The vacuum drying (test) oven series manufactured by HINOTEK offers short heating times, precise control, safety and reliability, while gently drying heat-sensitive and easily oxidized materials. Our instruments use digital pressure sensors for microcomputer-based automatic control of vacuum level and the vacuum pump.
Product Features
The rectangular chamber provides a large usable volume, and a microcomputer temperature controller provides precise, reliable control.
A double-layer tempered, bullet-resistant glass door provides a clear view of objects inside the chamber. Inert gas can be admitted.
Door-closing tightness is adjustable, and a one-piece molded silicone-rubber door seal ensures a high vacuum inside the chamber.
The stainless-steel sheet chamber ensures durability and is easy to clean.
Storage, heating, testing and drying can be performed without oxygen or in an inert-gas atmosphere without causing oxidation.
Drying time is reduced by more than 50% compared with conventional vacuum drying ovens;
Drying Process Control
Vacuum drying process control provides programmed vacuum cycles. Setting the highest and lowest vacuum values separately according to your requirements can further shorten drying time. For example, a programmed vacuum cycle can use a minimum vacuum of 50Pa, a maximum of 900Pa and 6 cycles, with the drying process as illustrated. Humidity decreases with each cycle, significantly accelerating drying. Up to 99 cycles are possible;
Cyclic Programmable Control
A user-friendly interface and programming save time and ensure reliable heating or drying processes. Programming can be performed directly on the interface, with 15 preset segments and 1~9999 minutes per segment. Start-up and shutdown times can be preset;
Vacuum Control
The vacuum drying (test) oven uses digital technology to control vacuum level. Manual control is a thing of the past: can a manually operated lever valve really control vacuum precisely in the 21st century? Automatic control through a digital vacuum gauge provides more precise, effective control. From the panel, vacuum can conveniently be controlled between any two points or within a region in the range of 10~10
5Pa (minimum achievable vacuum: 133Pa), with control precision of ±1%. The vacuum gauge uses a silicon resistive pressure sensor to ensure stable pressure readings unaffected by airflow, transmitting the stable pressure value to the gauge’s LED display;
Temperature Control Advantages
15-segment programmable function: in addition to conventional program-control mode, temperature and hold time can be set as “temperature~hold time at that temperature”. BPZ-LC also includes a ramp-mode program defined as “temperature—time—temperature”: the time required to rise or fall from one temperature to another, enabling accurate control of heating or cooling rate. Each heating, constant-temperature and cooling stage of the temperature experiment is therefore controllable;
