convection vertical diffusion circulation. The air circulation adopts the design of upper air outlet and lower
air return. The wind speed and air pressure meet the test
standards, and the temperature stabilization time is fast at the
moment of opening and closing the door. Optimized ventilation design, strong air supply and circulation,
avoid any dead angle, and make the temperature distribution in the
room uniform. More energy-saving, in line with current international and domestic
environmental protection requirements. Quieter, better to ensure a good office environment and the working
environment of operators. The extremely small tube volume and ultra-small volume ensure that
the room is bright, quiet, generous and beautiful. Easy installation, maintenance and repair.
High quality and reasonable design. | | Heater | Using high-efficiency nickel-chromium heating wire The heating system adopts the hot air circulation heating method,
the temperature distribution is uniform, the system is completely
independent, and the control circuit is not affected. The output power of temperature control is calculated by
microcomputer, and the heating power is automatically controlled
according to the size of the internal load, so as to achieve
high-precision and high-efficiency power consumption benefits, and
is more environmentally friendly and energy-saving. |
Refrigeration system (Optional, cost is additional) | Work performance | More energy saving, in line with the current international and
domestic environmental requirements. | | Refrigeration compressor | Quieter, better to ensure a good office environment and operating
staff working environment. | | Evaporator | Extremely small volume of tube and super small volume, to ensure
that the room is bright and quiet, generous, beautiful. | | Condenser | Easy to install, maintain and repair. | | Throttling device | High quality and reasonable design. | | Refrigerator control | All components have high reliability. | | Refrigerant | Environmental refrigerant R404A (Ozone depletion index is 0) |
Electrical control system | Controller | E600 Intelligent LCD touch screen PLC | | Monitor | 5.7 Inch 640X480 lattice TFT color LCD monitor | | Operation mode | The product adopts a resistive high-precision touch screen
operation mode, and you can directly use a USB mouse or a touch pen
to click on the screen to select functions or set parameters. | | The programmable function has a capacity of 160Patten×1600 step×999
cycle. | | Screen display function: LCD display, which can display test
conditions (including temperature segment, cycle times, running
time and remaining time, etc.). | | With program control and fixed value control functions, it is
convenient for the use of various production conditions. | | The setting of the temperature slope can freely control the running
time and the heating rate. | | Reservation start function, after the system time reaches the set
time, the system will run automatically, which can freely control
the running time and working conditions of the aging room. | | Power-off restart function, you can select cold start/warm
start/interruption for operation. | | The temperature control adopts P.I.D.+S.S.R. system synchronous and
coordinated control, which can improve the stability and life of
control components and interfaces. | | Real-time curve and historical curve query, which is convenient for
users to observe temperature changes in real time. | | History dump function. With two USB interfaces, it is convenient
for users to save historical data. | | File backup function. | | The external computer connection interface can be connected to the
computer for remote operation. It has the functions of saving and
printing curves and experimental data. | | Running the cumulative function, it is convenient for customers to
check the use status of the product for corresponding maintenance
and maintenance. | | Screen saver function, better prolong the life of the LCD screen. | | When the system is faulty, it can display fault information, fault
causes and solutions. | | It has the function of permission level setting to avoid user mis
operation. | | The function of switching between Chinese and English is convenient
for users of different languages to operate. | | Control mode: PID (proportional-integral-derivative) automatic
calculation, PID control is simple and easy to understand, and does
not require an accurate system model and other prerequisites in
use. | | In the setting, if an error occurs, a warning signal will be
provided. | | The on-off function can save costs for designers and increase the
convenience of use. | | Exhaust system | One set of exhaust system. Satisfy the temperature balance when the test product itself
generates too much heat in the aging room. When the aging room is overheated, the exhaust system is turned on,
so as to achieve the effect of balancing the indoor temperature. After the aging is over, the exhaust air is turned on. The exhaust duct is galvanized steel pipe, and the discharge
position is the position specified by the customer |
