Application of screw explosion-proof chiller 

Explosion-proof chillers are mainly used in special places that are flammable and explosive, such as chemical plants, ink printing plants, petroleum plants, etc. The cooling range is from 30kw to 600kw, and the temperature can also be made according to requirements, such as the commonly used 5 ~ 35℃, between 0~-40℃, or below -40℃. Here is a screw-type explosion-proof chiller.

The screw-type explosion-proof chiller is one of them, and can also be made into a box-sealed explosion-proof chiller according to customer preferences. All components of the chiller are designed and manufactured in accordance with national explosion-proof standards, and provide qualified explosion-proof certificates approved by relevant departments to meet the special needs of users. This water-cooled screw-type explosion-proof chiller is used in petroleum plants.

Since it is an explosion-proof chiller, compared with a standard chiller, it obviously has an additional explosion-proof function to ensure that the unit can operate safely and stably during use:

1. The compressor of the screw-type explosion-proof chiller is a professional explosion-proof compressor of Taiwan Han Bell brand. The screw compressor series not only is explosion-proof, but also can do four-stage capacity adjustment to play the role of energy saving and power saving.

2. Selected US Bangpu microcomputer control panel, you can clearly see the operation status of the unit, you can also adjust the temperature control temperature according to the cooling demand, and you can clear it to eliminate the unit fault according to the fault prompt on the control panel.

3. The use of South Korean LG explosion-proof electrical control system and Omron explosion-proof electrical accessories can protect the chiller from other interference and work safely and stably.

4. The shell-tube evaporator and condenser produced by the factory not only have sufficient heat exchange area, but the externally threaded copper tubes make the two devices have good sealing performance and strong heat exchange capacity, and can better continue the heat exchange cycle. Stabilize the refrigeration efficiency of explosion-proof chillers.

5. The freezing components of explosion-proof chillers are the same as standard chillers. If it is a low-temperature screw chiller, an economic separator is needed to ensure that the temperature can be controlled below 0°C.

6. The explosion-proof chiller is also equipped with various protection measures, such as phase loss and reverse phase protection, compressor overload/delay protection, high pressure/low pressure protection, automatic prompt protection for water shortage, low temperature/anti-icing protection, etc.


With the maturity of explosion-proof chiller technology, more and more chemical companies are already choosing this chiller. As a qualified supplier of chillers, Dongyuejin is responsible for shutting down every process in the production process of chillers to ensure that qualified and durable refrigeration equipment is delivered to users!
