Suitable for use in hazardous areas within Zone 1 (or Zone 2) of explosive gas mixtures with a temperature group of T4 in petroleum, chemical, pharmaceutical, aerospace, laboratory, storage, and other departments. BL series industrial grade integrated explosion-proof refrigerators are Class IIC explosion-proof refrigeration systems manufactured using integrated explosion-proof technology according to industrial environmental requirements.

The electronic temperature control system is adopted, and the electronic temperature controlled explosion-proof refrigerator is the second generation new product after the mechanical temperature controlled explosion-proof refrigerator. The main difference between electronic temperature controlled explosion-proof refrigerators and mechanical temperature controlled explosion-proof refrigerators lies in the temperature controller and its electrical circuit structure. The box structure and refrigeration working principle are roughly the same as mechanical temperature controlled refrigerators, and will not be repeated here.

Electronic temperature controlled stainless steel explosion-proof refrigerators are available in both direct and intercooled types, with a variety of control functions. In addition to controlling the start and stop of the compressor based on the temperature of the refrigeration and freezer, it can automatically display the temperature of the refrigeration and freezer. It also has functions such as automatic defrosting based on the thickness of the frost layer and the working time of the compressor, overvoltage protection, automatic deodorization, and language prompts. Generally speaking, electronic temperature control is more complex than mechanical temperature control. Both electronic and computer-controlled explosion-proof refrigerators are applications of fuzzy control systems, which solve the control problem of multifunctional explosion-proof refrigerators. However, due to the complexity of control, it also brings many inconveniences to maintenance personnel.

Most electronic temperature controllers use thermistor type temperature controllers (temperature sensors) because their temperature sensing probes have a smaller resistance as the temperature increases and a larger resistance as the temperature decreases. By utilizing this feature, the compressor can be started and stopped, thereby achieving circuit control.

The entire machine adopts ultra weak current technology to isolate intrinsically safe circuits. After special manufacturing processes and explosion-proof treatment, the design and manufacturing of the product strictly follow relevant standards:

GB 3836.1-2000 "Electrical Equipment for Explosive Gas Atmospheres - Part 1: General Requirements"

GB 3836.2-2000 "Electrical Equipment for Explosive Gas Atmospheres - Part 2: Flameproof Type" d "

GB 3836.3-2000 "Electrical Equipment for Explosive Gas Atmospheres - Part 3: Increased Safety" e "

GB 3836.4-2000 "Electrical Equipment for Explosive Gas Atmospheres - Part 4: Intrinsically Safe" i "

GB 3836.9-2006 "Electrical Equipment for Explosive Gas Atmospheres - Part 9: Encapsulated" m "

The product surface adopts surface temperature limit protection technology, comprehensive anti-static technology, and various safety protection technologies;

Voltage: 220V/50Hz;

If non-standard, various specifications and usage temperatures can be designed and produced according to user requirements.

This series also has 150 liters, 200 liters, 240 liters, 300 liters, 400 liters, and 500 liters
