The explosion-proof incubator is a microorganism cultivation apparatus featuring a dual-temperature control system with both refrigeration and heating capabilities, capable of timed operation. It serves as vital experimental equipment in laboratories across sectors including public health and epidemic prevention, genetic engineering, environmental protection, pharmaceutical testing and manufacturing, animal husbandry and aquaculture, water analysis, BOD determination, plant cultivation, breeding experiments, and food science. It finds extensive application in low-temperature constant-temperature testing, cultivation trials, and environmental testing.
1. The product complies with IIB explosion-proof standards and is suitable for hazardous locations with explosive gas mixtures in temperature classes T1 to T4. It achieves an explosion-proof rating of IIB T4. The product has been certified as compliant by the ****** Electrical Safety Quality Inspection and Testing Centre and holds a valid ********* explosion-proof certification;
2. The electrical control system employs a composite explosion-proof technology combining flameproof and encapsulated designs. The operating switch is a passive switch that generates no mechanical sparks during operation, ensuring safe and reliable use. Sensors are equipped with external safety barriers for explosion-proof isolation;
3. The explosion-proof digital temperature controller features a menu-driven interface with a 5.7-inch LCD screen. It includes a standard auto-lock screen function to prevent accidental operation; A single screen displays set temperature, operating temperature, constant temperature duration, heating status, and other information, ensuring straightforward operation. The microprocessor-based PID control system delivers precise temperature regulation with minimal fluctuation;
4. The intelligent microprocessor temperature control system incorporates PID logic operations. Based on calculation results, it automatically corrects temperature deviations to achieve precise control;
5. Incorporates a programmable start function with multiple timing modes: forward countdown, reverse countdown, constant temperature timing, and start-up timing. Timing units are selectable in minutes or hours;
6. Core components (refrigeration cycle) utilise imported brand compressors and circulation fans. The compressor employs cast-sealed explosion-proof technology for safety and reliability. Utilises fluorine-free, environmentally friendly refrigerant to foster a healthy laboratory environment;
7. The internal air circulation system employs a high-temperature resistant, low-noise explosion-proof axial fan for forced circulation. The refrigeration system features a classic arrangement proven stable through years of market testing, ensuring safety and reliability;
8. Automatically monitors operational status. Upon exceeding the limit temperature, heating is automatically cut off with audible and visual alarms alerting operators to ensure uninterrupted experiments. Parameters are automatically saved during emergencies, with power-on recovery functionality. Additionally, it incorporates sensor self-diagnosis, over-temperature, and fault alarm capabilities;
9. The inner chamber employs 304 mirror-finished stainless steel with rounded corners, while the outer casing utilises premium cold-rolled steel plate with electrostatic powder coating. The finish is durable, long-lasting, and anti-static;
10. Magnetic seal door facilitates easy opening with excellent sealing performance; adjustable shelves optimise space utilisation;
11. Double-door construction allows 360-degree observation of the working chamber through the inner tempered glass door when the outer door is open, without affecting internal temperature.
