Shenhai a prova d'explosió
Equip de classe A designat per a la zona d'explosió de pols 21 es caracteritza per una temperatura superficial màxima de TA 85°C. En entorns on s'han de prevenir les explosions, l'aire pot contenir materials inflamables i explosius com gasos, vapors, pols, i fibres. Explosions can occur when these substances come into contact with sparks, flames, certain temperatures, or specific air pressures. It is therefore critical to take measures to prevent such explosions.

| An explosive environment in the air that continuously appears in the form of combustible dust clouds, exists for a long time or frequently. | Places where explosive environments in the air may appear or occasionally appear in the form of combustible dust clouds during normal operation. | In the normal operation process, an explosive environment in the air in the form of combustible dust clouds is impossible to occur in places where the instrument exists for a short period of time. |
This highlights the importance of adhering to strict safety standards, especially in industrial environments where explosiu materials are present. The use of Class A devices, with their specified maximum surface temperatura, is a key strategy in mitigating the risk of explosions. These devices are designed to operate safely within explosive atmospheres by limiting their surface temperatures below the ignition temperatures of the surrounding inflamable materials.
The implementation of such safety protocols ensures that operations in hazardous areas remain secure and explosion-free, thereby protecting both personnel and infrastructure.
