MRI water chillers, chiller for MRI system, MRI equipment chillers
The chiller is an indispensable part of the MRI equipment, which provides effective cooling for the MRI equipment. There are two main parts of the MRI equipment that need to be cooled. One is the gradient coil and the other is the liquid helium compressor. The liquid helium compressor, because it is continuously working 24 hours a day.
MRI chillers Working PrincipleMRI chillers are mainly composed of four parts: compressor, evaporator, condenser and expansion valve. The compressor makes the refrigerant circulate in the system. The liquid refrigerant in the evaporator evaporates and absorbs the heat of the circulating water to lower the water temperature. The gaseous refrigerant is compressed by the compressor and flows into the condenser to dissipate heat and condense into liquid. After throttling and reducing the pressure by the expansion valve, it returns to the evaporator to continue circulating, thereby achieving the cooling of the circulating cooling water.
MRI chillers are used in medical instruments because of their numerous advantages:
1. MRI chillers are energy efficient and maintain the uptime of MRI machines by using chilled water circulation and two water pump configurations that steadily cool the cold head and prevent the machine from heating up, bursting and damaging.
2. The cold head is a special part of the MRI machine that converts gaseous helium into liquid helium by releasing a large amount of heat, which is absorbed by the efficient insulated heat exchanger and released from the machine, thereby preventing gas explosion.
3. MRI chillers are equipped with dual independent refrigeration circuits, configured with a constant flow of refrigerant, working independently to achieve the cooling effect. If one circuit is damaged, the other circuit will continue its performance.
4. MRI chillers use environmentally friendly refrigerants with closed-loop circulation, which prevents water from direct contact with ambient temperature, ultimately preventing the ingress of dust, clogging and corrosion.
5. MRI chillers use branded silent scroll compressors and sound insulation materials for quiet operation.
MRI chillers Function
1. Maintain stable operation of the equipment: A large amount of heat is generated during the operation of the MRI equipment. The chiller provides a constant low temperature environment through circulating cooling water to ensure that the equipment operates within an appropriate temperature range, reduce the failure rate, and extend the service life.
2. Improve diagnostic accuracy: It can effectively reduce the internal temperature of the equipment, reduce the impact of temperature fluctuations on the magnetic field, improve the stability of the imaging magnetic field, and thus improve the diagnostic accuracy.
3. Reducing electromagnetic radiation: It can reduce the internal temperature of the equipment, thereby reducing the level of electromagnetic radiation, and further ensure patient safety.
Applications for MRI chillers:
MRI Chiller is the best cooling device for medical equipment and other clinical applications as: Radiation therapy, cyclotron system, CT scanning, MRI medical machines, cancer treatment, blood cooling, laboratory samples preservation, surgical equipment, body fluids protection, and linear accelerators, etc.In order to help you choose a suitable chiller for MRI system, we need to know some information from you：1. Cooling capacity of the chiller(kw or Kcal/h)? Or you also tell us the power or calorific value parameters of the MRI equipment.2. Chilled water flow (L/min or m3/h) and output temperature range?3. The water flow and pressure of Built-in pump of the chiller?4. Power Input 380V, 50Hz is ok for you or not?5. You will put the chiller indoor or outdoor to use?6. Environmentally friendly refrigerant, we advise to use R407C. Sure, we also have R410A, R134A for you too choose.
