We can also custom design and manufacture chemical chillers to meet your specific needs.If you need a chemical chiller for a different chemical process? Contact Us–we’re here to help.

1.What is Chemical Chillers ?

Chemical &Pharmaceutical Chillers are cooling machines providing low-temperature cooling water, reduce the temperature of the chemical machinery and pharmaceutical cooling processing.
The pharmaceutical industry prepares medicines by processing through different heating and cooling parameters as blending, extrusion, mixing firmly adjusted by the unique efficient working of Pharmaceutical& Chemical Chiller.

2.Applications of Chemical Chiller in Chemical Mechanical Cooling:

(1). Low-boiling point organic matter condenses rapidly. In chemical reactions, the chemical chiller can accurately control the temperature;
(2).Chemical chillers determine the quality, output and cost of chemical products to a large extent.
(3). In the reactor kettle, biochemical reactions need to maintain low temperature conditions. The chiller can provide rapid cooling of raw materials to prevent drug deterioration, low-temperature crystallization extraction, low-temperature extraction and low-temperature drug synthesis.

3.What’s the Difference Between Air-cooled & Water-cooled Chemical Chillers?

There are two types of brewery chiller: one is air-cooled chemical chiller ,the other is water-cooled chemical chiller ;

Air-cooled chemical 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 chemical 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 chemical chiller.

4.What is the Difference Between Chemical Scroll Chiller and Chemical Screw Chiller?

Chemical Scroll Chiller Chemical Screw Chiller

▪1/2 HP-60HP(2KW-170KW) Above 60HP(Above 170KW)

▪ Danfoss/Panasonic Scroll Compressor Hanbell/Bitzer Screw compressor

▪Built with water tank and water pump Without water tank and water pump

5.What Are The Main Components of Chemical Chillers?

5.1 Compressor

The compressor is the key mover in chemical chiller because it produces pressure variations to stir the refrigerant around.

From 1/2HP(1/2 Ton) to 60HP(5oTon) chemical chiller , which is with Panasonic or Danfoss brand Scroll compressor ,
Above 80HP(70 Ton) chemical chiller , which is with Hanbell or Bitzer brand Screw compressor ,
These brand compressors are with high refrigeration efficiency,low noise ,energy saving,environmental protection and durability,safety and stability.

5.2 Evaporator

The evaporator is a crucial component of air-cooled chemical 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.

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

5.4 Condenser

The condenser for air-cooled chemical chiller 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.

The condenser for water-cooled chemical 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.

5.5 Controller Panel
Chemical chillers use precision digital temperature controller, it RS485 communication port，which can do remote monitoring and control. Simple operation, low failure rate, high safety factor, easy installation.

6.How to Choose Right Chmecal Chiller for Your Chemical Process?

How to calculate right cooling capacity for your chemical chillers?

One of the most frequently ask about how we can know the cooling capacity for chillers. 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 chemical chiller system?
There are two types of chiller :Air Cooled chemical Chiller and Water Cooled Chemical 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.

Cooling capacity unit conversion?

1 KW=860 kcal/h ;

1 TON=3.517 KW;

1 KW=3412 Btu/h;
