Links | Sitemap | RSS | XML | Privacy PolicyTongwei portable recirculating water chiller is a cooling system engineered for industrial,medical,laser processing and laboratory application .It includes the refrigeration circuit, controls and electrics, process water pump and reservoir(water tank) all within a single unit. Built with Stainless steel evaporator and hermetic scroll compressor,it delivers precision water temperature control (-40℃ to 35℃).
Portable recirculating water chiller has four footprints, are mobile and are located near the process or machines being cooled. The capacity of these water chiller usually range from 1KW to 50KW in cooling capacity .The chiller uses PID temperature control with real-time monitoring ensures accuracy ± 0.1℃,which is critical for laboratory ,semiconductor manufacturing and pharmaceutical processes.Tongwei water chiller is with dual safety protection(low water level,overheat,phase failure alarms) prevents chiller damage and downtime.
»Standard portable recirculating water chiller cooling capacity available from 1/2 tons – 10 tons

»Eco-friendly R410A /R407c refrigerant ensures compliance with global environmental standards.
There are five 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.
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 .
whether it is portable, compact, large and small recirculating water chillers, we can custom design them according to your requirements. no matter how many /KW/tons of chiller you need , we can give you our the best solution.
Tongwei provide recirculating water chillers of various refrigeration types, including but not limited to air-cooled chiller and water-cooled chiller regardless of the type of refrigeration compressor, we can design it according to your requirements.
Tongwei can create a custom solution for temperatures from -40℃ to 35℃ ±0.1°C stability. Custom temperature ranges for specific industries.
Customize chiller voltage and phase according to your needs. Optional 220V/60HZ, 380V/50HZ, 400-415V/50HZ, 460V/60HZ, 440V~480V/60HZ, etc for different countries.

Durable, reliable chiller machine & Competitive Price
Our portable recirculating water chillers are manufactured from high quality materials and we offer a competitive warranty on all industrial chillers.
As a professional Portable recirculating 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 .
