A portable air cooled MRI chiller is specially designed refrigeration device that is used for cooling purposes in MRI machines, working on refrigeration principle producing cooling effect either by using air for heat transferring.The chiller circulates water through coils inside the MRI machine to keep it at a consistent temperature.The working principle of MRI chiller is like this :it works by circulating a refrigerant around a series of coils. As the refrigerant circulates, it absorbs heat from the MRI scanner. This process helps keep the scanner cool and prevents it from overheating. The cold refrigerant then passes through a condenser, which turns it back into a liquid. The liquid refrigerant is then circulated back to the MRI scanner to start the process over again.
MRI Chillers designed and manufactured by Tongwei are with a range of cooling capacity from 5KW to 200KW ,which made of scroll Panasonic/Danfoss compressor, air/water-cooled condenser, stainless steel coil in water tank evaporator , power reverse phase, microprocessor, stainless steel water pump, and protecting devices, etc.The most important is MRI chiller is with R485 communication port for remote control.

Panasonic Compressor
Danfoss Compressor
The evaporator is a crucial component of portable 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 : stainless steel coil in water tank evaporator , 304SS stainless steel plate type evaporator.
Coil in SS Water Tank Evaporator
SS Plate Type+ Water Tank Evaporator
The water pump is designed to increase the pressure and the flow of the chilled water in a closed space,and we use stainless steel material water pump for laboratory chillers.
Water Pump
The condenser for portable air-cooled MRI 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.
Aluminum fin+fan 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.
Controller Panel
There are TWO main types of chillers that are used for MRI machine: air-cooled and water-cooled. The choice of chiller type depends on a number of factors, including the size and shape of the MRI machine, the climate where it will be located,installation ways and the electrical power available
✸ Air cooled MRI chillers use ambient air to dissipate heat from the MRI processes. They are energy-efficient, space-saving, and less maintenance that helps save money.
Air-cooled MRI Chiller
✸ Water cooled MRI chillers use water from an external water cooling tower to dissipate heat from the MRI processes. These systems are longer lifespan, Relatively quiet, and more consistent cooling performance than the air-cooled MRI chiller.
Water-cooled MRI Chiller
Should you choose an air-cooled or water-cooled MRI chiller? Contact Us for help determining the best solution for you.
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.
Chiller sizes are traditionally listed according to Ton,KW, But/h,Kcal/h. Tons does not refer to the actual weight of the chiller, but instead is a historical reference to a time when blocks of ice were harvested for cooling. Just like engines are still measured according to “horsepower”, the term “tons of refrigeration” stuck around:
1 KW=860 kcal/h ;
1 TON=3.517 KW;
1 KW=3412 Btu/h;
There are two types of chiller :Air Cooled MRI Chiller and Water Cooled MRI Chiller.
Water cooled chiller needs a separated water cooling tower and water cooling pump ,if you don‘t have existing water cooling tower,we suggest you use air cooled chiller; But if your ambient 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.
But Most customers use air cooled MRI chiller ,which is more easily install and save space.
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 with buffer tank.
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.
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.
As a professional portable 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 .
