200Kw 80Hp Explosion Proof Air Water Screw Chiller
What Is an Explosion-Proof Chiller? Explosion-proof chillers have a reinforced design to protect the chiller's components from ambient flammable materials that could cause an explosion.
How does explosion proof chiller work?
Many designs have all the chiller parts and electronics housed in a continuous explosion-proof housing made of durable materials such as stainless steel. This enclosure protects the device from excessive mechanical shock during operation. These considerations are essential, as an explosion-proof chiller can be a substantial investment. Regular chillers can be customized into explosion-resistant devices through this design.
The Explosion proof grade of this 80HP chiller is EXDIIBT4.
What does the explosion proof grade mean?
Definition of explosion-proof equipment: electrical equipment that will not cause ignition of the surrounding explosive atmosphere under specified conditions.
Explosion-proof products have an explosion-proof grade, and the explosion-proof form and applicable occasions of the product can be seen from the explosion-proof grade. For example, the explosion-proof level of Exd II BT4 is described below.
Ex: Explosion-proof mark
d: The explosion-proof form is explosion-proof type. There are also intrinsically safe types ia, ib; increased safety type e; oil-filled type o; sand-filled type q; potting type m;
II: Refers to Class II explosion-proof electrical equipment. This type of explosion-proof electrical appliances is suitable for other explosive gas environments except coal mines. (Coal mines are Class I). There is also class III: electrical equipment for explosive dust atmospheres other than coal mines. Class IIIA: flammable flying flocs; Class IIIB: non-conductive dust; Class IIIC: conductive dust.
B: Class IIB gas. There are also IIC and IIA grades. Level IIC is the highest level and can be applied to both IIA and IIB. Level IIB can be applied to Level IIA. But the low-level can't apply to the high-level.
T4: The temperature group is T4, and the maximum surface temperature of the equipment is less than 135°C.
