Why Explosion-Proof Chillers Are So Important

In order to protect the safety of employees and facilities, reducing the likelihood of explosions becomes the primary goal of any business owner. Some work-sites are more dangerous than others. Reduce the risk that sparks from the chiller could ignite explosive or flammable materials, which is why explosion-proof chiller is a safety requirement in many industries. Although the price of all explosion-proof equipment is high, the cost is far less than the loss of life caused by industrial accidents due to the use of the wrong machinery.

In addition to safety concerns, explosion-proof chillers are required by law in many locations where with combustible materials in the air. In addition to the danger of igniting flammable substances, non-compliance could result in huge emissions.

How Does a 15 Ton Air Cooled Hazardous Process Explosion-Proof Chiller Work?

There are many types of explosion-proof chillers, and how each one works depends on the components used. For example, there are screw and scroll compressors, air-cooled and water-cooled condensers. The components of the chiller system are not explosion-proof. The design of the entire system. But these components determine the ultimate efficiency of the chiller and the temperatures it can reach. Use this information when choosing a chiller for your workplace.

Most chillers operate in the same way, in short, by continuously flowing refrigerant to the cold end of the evaporator at the desired temperature. The chiller then pumps the cooled fluid through the process to dissipate heat from the equipment and funnel it back to the return side. The range of chiller we choose is -60 F to 30 F. If you have any special requirements for the cooling of chiller, please contact us .

The refrigerant starts the process in a mixture of liquid and gas. The gas and liquid enter the evaporator, where the heat converts the refrigerant into a low-pressure gas. This gas enters a compressor, which compresses the gas to a high pressure state using one of several methods. This gas moves to the condenser, which can cool the refrigerant with water or air. In a condenser, the coolant releases heat and condenses into a liquid. When the liquid is at high pressure as it passes through the expansion valve, the expansion valve controls how much cooled refrigerant enters the evaporator and starts the cycle again.

Danfoss Compressor

5.2 Evaporator

The evaporator is a crucial component of explosion proof chiller, as it is responsible for extracting heat from the liquid being cooled,it is located between the compressor and the expansion valve. There are three types of evaporators : coil in water tank evaporator , shell and tube evaporator, 304SS stainless steel plate type evaporator.

Coil in SS Water Tank Evaporator

Shell and Tube Evaporator

5.3 Water Pump

The water pump for explosion proof chiller is explosion-proof .

5.4 Condenser

The condenser for air cooled explosion chiller is equipped with efficient cross-seam fins and female threaded copper tubes for high heat exchange efficiency and good stability. The fan on the top of explosion proof chiller is also explosion proof .


Aluminum fin+fan Condenser for explosion proof chiller

The condenser for water-cooled explosion proof chiller is shell and tube ,with the internal copper tubes employing an outer thread embossing process.This design effectively enhances the heat exchange efficiency between the refrigerant and water during the process. Compared to traditional smooth copper tubes, the outer thread embossing process increases the surface area of the copper tubes, thereby expanding the contact area for heat exchange and improving the thermal conductivity of the condenser. This optimization design allows the condenser of the water-cooled chiller to transfer heat from the refrigerant to the water more rapidly and consistently, enabling the water to carry away the heat.

6.What are the Applications of a 15 Ton Air Cooled Hazardous Process Explosion-Proof Chiller?

We equip our explosion-proof chillers with extra features and rugged materials to ensure reliable operation in critical applications for many years to come. From nuclear science to plastics and rubber, custom explosion-proof chillers are used in many applications and protect your employees and facilities.Explosion-proof chillers have a variety of applications where cooling and protection from any type of explosion is required, including as below :

Chemical Plants

Chemical factories may generate or store potentially flammable substances. Even in storage spaces, the facility will need explosion-proof equipment.

Petrochemical Plants

To distinguish a petrochemical plant from an oil refinery, the former manufactures substances from petroleum while the latter refines crude oil. Both handle hazardous materials. The popularity of many petrochemicals, such as gasoline, is partly due to their flammability. The same properties also put petrochemical plants at risk of fire.

Cooling Flammable Liquids

Flammable liquids often emit hazardous vapors. These vapors make explosion-proof chillers and other equipment in the space required. If the fluid remains sealed, the area will only require Class I, Division 2 approved equipment.


Petrochemical refinement requires extreme caution with all materials used. Flammable gases produced in refineries require Class 1 explosion-proof chillers.

Sample or Process Analyzers

Using sample or process analyzers, workers can identify the chemical makeup of various substances. Explosion protection in the sample analysis area saves lives as the components are unknown and potentially harmful elements.


Flour is very flammable. Ask anyone who lives near a granary and has heard stories of the explosions. The fine dust in the air only needs a small spark to detonate. This is why silos and grain bins require explosion proof equipment.


Ventilation in laboratories is critical to the safety and health of workers. Fire safety and explosion protection are also important. Anywhere volatile, flammable vapors or gases are present, special electrical components are required to prevent stray sparks that could ignite.

How I Can Choose The Right Explosion-proof Chiller System?

There are four important chiller specifications you need consider when you choose a chiller for your application :the voltage required for operation, the associated pump horsepower and flow rate (contact us for custom selection), refrigerant, and the evaporator type.

7.1 Power

Different countries and regions have different standards for industrial electricity, the common power supplies are 208-230V, 380-420V,440-480V,50Hz or 60Hz, 3phase.

Such in Philippines ,the power supply is 220V 60HZ 3PH , 380V 60HZ 3PH ,460V 60HZ 3PH;

in Singapore and Malaysia ,the power supply is 415V 50HZ 3PH;

in Mexico ,the power supply is 220V 60HZ 3PH;

In USA ,the power supply is 208V 60HZ 3PH;575V 60HZ 3PH;480V 60HZ 3PH and so on

7.2 Water Pump

When you decide the capacity/tonnage of the chiller, we will recommend you the suitable pump in KW,which standard water pump is about 2 bar .If you need more high water pressure , please us when you inquiry.

7.3 Refrigerant

R22, R410A, R407C, R404A, R134A are optional choices.

R22: good cooling effect, but R22 is considered a powerful greenhouse gas, so it’s forbidden in most countries.

R410A: eco-friendly, R-410A has replaced R-22 as the preferred refrigerant for use in residential and commercial air conditioners in Japan, Europe, and the United States. R-410A operates at higher pressures than other refrigerants.

R407C: a good replacement for R22, good cooling effect.

R404A: suitable for application that requires low temperature(below -10°c).

R134A: a non-flammable gas used primarily as a “high-temperature” refrigerant, suitable for air-cooled chiller working at a high ambient temperature above 50℃.

7.4 Evaporator Choose

Chillers generally have two types of evaporators: one is coil in water tank evaporator ,the other one is shell and tube evaporator.

Coil and tank evaporator, which has a built-in water storage tank for more convenient use,so there’s no need for extra buffer tanks. This is also our standard evaporator for chiller , if you don’t have buffer tank ,we just use this evaporator for your chiller.

Shell and tube type evaporator, which requires an additional water buffer tank to connect .

8.Shipping Way of Explosion-proof Chiller

As a professional water chiller supplier &exporter,we have our own shipment forwarder to arrange the shipment .Our chiller machine is with plywood packing,which prevent damage during transportation and meet export standards.There are three ways can delivery your chiller unit :

1. Ship by Air: As the chiller is with compressor ,water pump and fans ,the compressed refrigerant and oil inside the compressor is a dangerous item with the possibility of explosion , so it needs to release the compressed refrigerant before transportation. (It means that water chiller without refrigerant when choosing this shipping way. After the machine arrives at your destination, you need to add refrigerant by local professionals. The airline company also request us to provide many documents to prove that the chiller not a dangerous product. The freight cost by air is very high may be higher than the cost of chiller , So By air for delivery is not the mode of transport recommended to our customer.

2. Ship by Sea: The transportation time is longer than by air , but the freight cost is cheap ,and there is no need to add refrigerant after the equipment arrives at the destination.This shipping way is the most suitable mode of transportation for you to delivery your local port.

3.If you have your own shipment container in your other supplier in China, we can help you delivery the chiller machine to your supplier in any city of China .
