Industrial explosion-proof air conditioning for chemical plants, Class IIC

Introduction

Explosion proof air conditioning is a type of explosion-proof electrical appliance, mainly used for cooling and heating in flammable and explosive environments such as petroleum, chemical, aviation, oil depots, and offshore oil platforms. The appearance and usage of explosion-proof air conditioning are the same as ordinary air conditioning. Explosion proof air conditioners can be classified into high temperature, low temperature, ultra-high temperature, and ultra-low temperature according to their working environment.

Overview

Explosion proof air conditioning products have cooling, heating, and automatic defrosting functions. The compressor, fan, and other components have undergone special explosion-proof treatment, and the explosion-proof type is the whole machine explosion-proof air conditioning. Explosion proof air conditioning can be used in flammable and explosive mixed gas environments such as petroleum, chemical, pharmaceutical, scientific research, military, and dangerous warehouses. In terms of structure, composite explosion-proof technologies such as explosion-proof, intrinsic safety, and sealing are adopted. The control end is fully controlled by intrinsic safety, which does not generate any electric sparks and is convenient and safe to use. An efficient multi fin heat exchanger is used, and the contact between cold coal and air is more complete when passing through, which can greatly improve the cooling and heating effect of the air conditioner. There are two types of manual control and remote control. Explosion proof air conditioners cannot be produced or sold without obtaining a production license.

Scope of Application

Explosion proof air conditioner, suitable forClass II B or C, temperature group T1~T6, explosion-proof air conditioning in hazardous areas containing explosive gases, Zone 0, Zone 1, Zone 2; And for use in all hazardous areas of Zone 20, Zone 21, or Zone 22 containing explosive dust and air mixtures (orders must specify). Explosion proof air conditioning is mainly used in petroleum, chemical, and military industriesworkThe cooling and heating of flammable and explosive environments such as oil depots, chemical warehouses, and offshore oil platforms, as well as the appearance and usage of explosion-proof air conditioners, are the same as ordinary air conditioners. Explosion proof air conditioners can be classified into high temperature, low temperature, ultra-high temperature, and ultra-low temperature according to their working environment.

Operation precautions

1. Do not directly disconnect the power to turn off the explosion-proof air conditioner. After connecting the power, use the switch button of this air conditioner to turn on and off the explosion-proof air conditioner.

2.Explosion proof air conditioners should not block the air inlet and outlet of the air conditioner, nor should anything be stuffed into the air inlet and outlet of the air conditioner. Do not rotate the blades directly by hand.

3.Explosion proof air conditioners should not be charged when opening the doors or covers of the casing. If maintenance is required, the higher-level power switch should be cut off in advance.

4.The surface of the plastic casing of explosion-proof air conditioners is prone to static electricity hazards. Friction is prohibited and must be cleaned with a damp cloth. When wiping the air guide vanes, be careful not to misplace the blades.

5.Explosion proof air conditioner. If the explosion-proof air conditioner display panel displays an error code, please remember and immediately turn off the device (the code may vary depending on the model). Please contact usAnd provide detailed information on the product model and fault code.
