Cooled Incubator BICL-6003

​1. Working principle

​The low-temperature incubator accurately controls the temperature through a PID temperature controller, and uses a Pt100 high-precision temperature sensor to ensure that the temperature in the box is accurate, stable, and uniform. Adopting high-power fan and air duct structure design, the air flow is uniform and controllable, the temperature fluctuation is small, and the air flow is stable. With compressor refrigeration and electric heating tube heating, refrigeration and heating are automatically switched, so that the heating and cooling speed is faster, the temperature stabilization time is short, and the control accuracy is high. It can provide storage of culture media, serum, medicines, microbial cultivation, environmental testing, etc. It is an ideal constant temperature equipment for scientific research institutions such as environmental protection, sanitation and epidemic prevention, drug inspection, farming and livestock, and aquatic products.

2.​Scope of application

​The temperature control range of the incubator is -10~80°C. It can provide high temperature culture environment and low temperature environment. It is an ideal experimental equipment for microbial culture, BOD test culture and other experiments. It is widely used in the storage of culture media, serum, and medicines. Microbial cultivation, environmental testing, etc., are ideal constant temperature equipment for scientific research institutions such as environmental protection, sanitation and epidemic prevention, drug inspection, agriculture and livestock, and aquatic products.

5.2 Structure function overview

The Cooled Incubator series low-temperature incubator is composed of a cabinet, a temperature control system, a heating tube, a blast system, a refrigeration system, etc. The cabinet is made of high-quality steel plate, and the surface is sprayed with plastic. The inner tank is made of high-quality galvanized sheet or mirror stainless steel. It is composed of plates (for users to choose), and the heat insulation layer is filled with ultra-fine glass wool.

The main component of the temperature control system is the temperature control instrument, which is a microcomputer intelligent controller composed of a single-chip microcomputer and peripheral circuits with a dual-row LED four-digit display. It uses Pt100 platinum resistance as the temperature sensing element, and uses PID adjustment to control the heating system and control the temperature. The instrument also has functions such as timing control, temperature control error correction, deviation alarm protection and so on. This series of products have the advantages of high temperature control accuracy, small overshoot, small fluctuation and deviation over-temperature protection. In addition, an independent over-temperature protection system can be added according to the needs of users, which can improve the safety performance of the product.

Cycle: The number of program cycles, 0 means infinite cycles, other numbers, the corresponding number of cycles, such as 1, if the program only runs once, the device stops. Delay: Make an appointment to set the boot time. After setting the time here, return to the main interface and click the run button to start timing. After the time is up, the device will automatically run.

Explanation: 1. This controller has 8 groups of programs, each group of 8 steps, only need to set a stable target temperature value and the time needed to stabilize. For example: using the second set of programs, 100°C, constant temperature for 2 hours, fan speed 75%, 150°C, constant temperature for 4 hours, fan speed 100%, set as shown in the figure below:

Figure 6 2.

2. This controller is a general-purpose controller. If you find that there is no fan speed setting column in the program editing, it means that you have purchased equipment that does not have the function of adjusting the speed of the circulating fan.

8.3 Usage of "Over-temperature Protector"

The over-temperature protector is an independent protection system. When the temperature is out of control due to the failure of the thermal controller and the room temperature of the chamber reaches the set value of limiting temperature in the over-temperature driving plate, the over-temperature protector will automatically cut off heating and alarms. (As shown in the left diagram) when the room temperature of the chamber is lower the limiting temperature value, the protecting system will be off and the meter resumes to normal. It will repeat like this till the breakdown is eliminated.

The particular operation is as follows:

1) The set value of limiting-temperature should be greater than or equivalent to (SV+AL)+(2~5)°C

2) Set the required limiting temperature as per need by using the "+" "-" buttons on the over-temperature setting plate of the penal For example: SV=37°C, AL=2, then set 42°C.

8.4 Operation precautions

1) Turn off the power after each use;

2) If it is not used for a long time, the cabinet must be cleaned inside and outside, and the plastic dust cover on the power plug must be unplugged;

3) If the storage environment has high humidity, it should be energized and heated regularly (about 1 month) for damp-removal treatment;

4) Before reuse or when the process requirements change, the temperature control accuracy should be checked;

5) In addition to the temperature setting, time setting, program setting and other parameters that can be changed, other function menu parameter adjustments need to be approved by our company's service center or operated by professionals.

9. Cleaning and maintenance

1) Routine maintenance, clean and maintain the equipment regularly, wipe the liner and shelf regularly with a dry cloth to make the liner clean and free of foreign matter;

2) Routine maintenance, regular cleaning of the outer surface, pay attention to the impact of the return to the city on the air door and test hole;

3) Long-term maintenance. If it is not used for a long time, the cabinet must be cleaned inside and outside, unplug the power plug and cover the plastic dust cover, and regularly (about 1 month) power on for damp treatment.
