1.What is Plasma Cutting Chiller ?
Plasma cutting Chiller is a process cooling machine that is used to control temperature during spray processing by releasing out heat from the equipment.
The plasma cutting process uses an accelerated jet of hot plasma to transfer energy to the conductive work material. Plasma cutting is commonly used in industrial construction, manufacturing shops, salvage and scrap operations, and automotive repairs.
In these applications,plasma cutting chillers are used to provide stable temperatures during the plasma cutting process. Plasma cutting chillers maintain the integrity of your plasma cutting system with superior performance, providing years of reliable liquid temperature control.

2.What are the benefits of Plasma Cutting?
▪ Plasma cutting is simple to use so it can be operated by hand or robot.
▪ Plasma cutting is more economical than other types of cutting.
▪ Plasma cutting can be used on a wider range of materials, such as stainless steel and aluminum. unlike laser cutting or oxy-fuel cutting, plasma cutting has a high-quality cut edge, which means it doesn‘t leave jagged edges on the cut edges.

3.Why are Plasma Cutting Chillers Useful?
In order to achieve the above goals, the key is to remove the heat during the plasma cutting process, which can be achieved through a plasma cutting cooler cooling system. It can be designed in various refrigeration capacities to meet customers‘ specific cooling requirements.
4.What’s the Difference Between Air-cooled & Water-cooled Plasma Cutting Chillers?
There are two types of plasma cutting chiller: one is air-cooled plasma cutting chiller ,the other is water-cooled plasma cutting chiller ;
Air-cooled plasma cutting chillers use ambient air to dissipate heat from the brewing processes. They are energy-efficient, space-saving, and less maintenance that helps save money.
Water-cooled plasma cutting chillers use water from an external water cooling tower to dissipate heat from the brewing processes. These systems are longer lifespan, Relatively quiet, and more consistent cooling performance than the air-cooled pl chiller.

6.What Are The Main Components of Plasma Cutting Chillers?
6.1 Compressor
The compressor is the key mover in water chiller because it produces pressure variations to stir the refrigerant around.
From 1/2HP(1/2 Ton) to 60HP(5oTon) plasma cutting chiller , which is with Panasonic or Danfoss brand Scroll compressor ,

6.2 Evaporator
The evaporator is a crucial component of air-cooled water 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.

6.3 Water Pump
The water pump is designed to increase the pressure and the flow of the chilled water in a closed space.

High Pressure Water Pump
6.4 Condenser
The condenser for air-cooled plasma cutting cooler is equipped with efficient cross-seam fins and female threaded copper tubes for high heat exchange efficiency and good stability.Its function is to cool down the refrigerant steam released from the compressor into a liquid or gas-liquid mixture.
Aluminum fin+fan Condenser for air -cooled plasma cutting chiller
The condenser for water-cooled plasm spray cooler 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.

8.How to Choose Right Laser Chiller for Your Plasma Cutting Process?
How to calculate right cooling capacity for your plasma cutting chillers?
One of the most frequently ask about how we can know the cooling capacity for chillers.
The range of a chiller at which it can discharge heat from a heated fluid is called cooling capacity.
The cooling capacity of a laser Chiller ranges from 1/2KW to 100KW.
Let’s see the below formula.
Cooling Capacity(kw)= Flow Rate(m3/h)*Temp Change(T1-T2)/0.86
Heat Load= C(specific heat)* M(quality output per hour )*Temp Change(T1-T2)
Oversize the chiller by 20% Ideal Size in KW = KW x 1.2
Noted : T1:Incoming Water Temperature (℃) T2:Required Chilled Water Temperature(℃)
For example, what size of chiller is required to cool 5m³ water from 25°c to 15 °c in 1 hour?
Temperature Differential = 25℃-15℃=10℃
Water Flow Rate = 5 m³/hour
Cooling Capacity in KW = 5 x 10 ÷ 0.86 = 58,14 KW
Oversize the chiller = 58.14 x 1.2 = 69.76 KW
69.96kw cooling capacity for chiller is required.
Types of plasma cutting chiller system?
There are two types of chiller :Air Cooled Plasma Cutting Chiller and Water Cooled Plasma Cutting Chiller.
Water cooled chiller needs a separated water cooling tower and water cooling pump ,if you don‘t have exsiting water cooling tower,we suggest you use air cooled chiller; But if your ambiemt temperature is very high above 55℃ ,we suggest you use water cooled chiller , as it is easier to dissipate heat for water cooled chiller with water cooling tower.
Whether chillers need built-in Tank or not？
In a chiller system, a tank is usually equipped to buffer the thermal load of the chiller.
But should we choose a built-in type of tank or an external type of tank?
A chiller with a built-in tank is easier to install and can be used simply by connecting a water pipe to your application.
But it has a limited capacity and is not suitable for applications with larger chilled water demands.External tank’s capacity can be customized according to specific needs.
It can buffer a larger heat load, store more chilled water, but the installation will be more troublesome.
If you don‘t have external water tank ,we suggest our chiller built-with water tank ,which is easy for you to install.

1 KW=860 kcal/h ;
1 TON=3.517 KW;
1 KW=3412 Btu/h;
