High Pressure Water Pump
The condenser for packaged water cooled glycol 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.
Shell and tube Condenser
Tongwei 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.

There are two types of low temperature chiller: one is air-cooled low temperature chiller ,the other is water-cooled low temperature chiller ;
Air-cooled low temperature 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 low temperature 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 brewery chiller.

The most commonly used coolant in a chiller is water or a mixture of water-glycol. Glycol-based coolants consist of either ethylene glycol or propylene glycol. The main advantage of glycol coolants is their anti-freeze properties. Pure water freezes at 0 degrees C, while 30% ethylene glycol freezes at -14 degrees C. The low freezing point of glycol mixtures makes them ideal for cooling items that are below the freezing point of water. Although glycol has a lower heat capacity than water (each kilogram of glycol is easier to heat than one kilogram of water), the high temperature difference allows the glycol mixture to dissipate heat more quickly than pure water. The glycol mixtures are more suitable for applications where the chiller must quickly dissipate a large number of heat. In addition to providing excellent heat transfer parameters, glycol tends to discourage algae growth in heat transfer equipment.

A glycol chiller is composed of a refrigeration component and tubing containing a water-glycol mixture as coolant. Chilled fluid from the refrigeration unit is channeled through the piping associated with a thermal exchanger surrounding a heated process. After absorbing heat from the associated process, the hot coolant is returned to the refrigeration unit for cooling after which the process is repeated.
A glycol chiller consists of a compressor, an evaporator, a condenser, a throttling element, and an electric control system. Let’s see what’s the working principle of a glycol chiller:
Glycol Chiller Working Principle
It is important to use the proper ratio of glycol to water mixture in the cooling system depends on the coldest temperature you need during operation, as insufficient glycol can cause the system to freeze, possibly bursting pipes and even destroying the chiller evaporator even may damage the glycol chiller, while too much glycol to a chiller system will result in an inefficient system.
But what’s the best ratio for glycol and water mixtures? Please see below glycol ratio of glycol and water mixtures for the glycol chiller in your cooling process:

Do you need a glycol chiller for an application not mentioned here? Contact us and we’ll customize an affordable solution for your exact demands.
There are four important chiller specifications you need consider when you choose a chiller for your application :the cooling capacity for chiller ,the voltage required for operation, the associated pump horsepower and flow rate (contact us for custom selection), refrigerant, and the evaporator type.
There are two types of glycol chiller: one is air-cooled type, the other one is water-cooled type.
Air Cooled glycol scroll chillers use aluminum fin+fan as condensers that is similar to the “radiators” in a car.They use a fan to force air through the refrigerant coil. Unless they are specifically designed for high ambient conditions, air-cooled condensers need to operate effectively at an ambient temperature of 45℃ or less.
Water Cooled glycol scroll chiller use shell and tube as condensers.The heat enters the condenser water from the refrigerant vapor. The warm condenser water is then pumped to the water cooling tower, where the heat from the process is eventually vented to the atmosphere.
One of the most frequently ask about how we can know the cooling capacity for chillers. We use KW ,Ton, But/h,Kcal/h to choose chiller cooling capacity :1 KW=860 kcal/h ; 1 TON=3.517 KW; 1 KW=3412 Btu/h;
There is also a formula to calculate the cooling capacity for chiller:.
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 10m³ water from 35°c to 15 °c in 1 hour?
Temperature Differential = 35℃-15℃=20℃
Water Flow Rate = 10 m³/hour
Cooling Capacity in KW = 10 x 20 ÷ 0.86 = 232 KW
Oversize the chiller = 232 x 1.2 = 278.4KW
278.4 kw cooling capacity for chiller is required.
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
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.
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℃.
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 .
As a professional low temperature glycol 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 .
