It is heat exchange machines that are being used to maintain temperature accuracy.

An MRI Chiller can be a significant purchase, so it is necessary to see how to keep up and maintain it to get good results and save your investment.

Below is the Checklist for Maintenance:

• Inspection should be done of all water inlets and outlets for leaks ought to be done regularly.

• All parts of the compressor unit ought to be inspected including checks for oil levels, leaks, vibrations, working temperature accuracy.
• Electrical contacts ought to be checked and cleaned regularly.
• Filter dryers ought to be checked, and dirty, old, or broken filters should be replaced completely.
• Cooling coils should be double-checked for distortion in fins, and indications of erosion.
• Condenser fan inspection ought to be done regularly. Belts and couplings ought to likewise be checked and changed when necessary.
• Condenser coils ought to be checked for leaks, corrosion, and areas blockage.
• For MRI Chiller, return air dampers ought to be examined for ideal operations, bearing alignment and lubrication should be done regularly.
• Fresh air dampers ought to be checked in the same way as to return air dampers.

Preventive Maintenance for your MRI Chiller:

Below are a few tips to maintain.

Maintain your Daily Logs: As necessary as this may seem, have a day-by-day record of working conditions.

The pressure, and temperatures in your MRI Chiller, just as the fluid levels and flow rates, could help and can predict future damage.

Keeping your MRI Chiller log sheet is worthwhile as a pre-emptive MRI Chiller maintenance schedule can be organized before any kind of damage.

Maintain Daily Logs of your MRI Chiller

Keep the Tubes Clean: The MRI Chiller working principle is dependent on heat transfer to exert a cooling impact.

In shells and tubes and brazed plate heat exchangers, a block to the progression of cooling fluid through the condenser will reduce the working efficiency.

Over the long run, corrosion can accumulate inside the chiller tubing and block the removal of produced heat.

Consequently, it is necessary that quarterly or yearly cleaning of your MRI Chiller tubes should be carried out.

Reduce the Temperature of the Condenser Water: Decrease the temperature of the water entering the condenser of an MRI Chiller, altogether improving the ability as it needs to work less to exert its cooling effect.

Although not suggested as standard work, reducing the temperature of the water going through the MRI Chiller’s condenser unit may serve as a measure to overcome problems of coils.

Examine the Condenser Water Loops： Some condensers have water loops that use open cooling sources, for example, air-cooling towers.

Because of this environmental exposure, there is a tendency for the water to be contaminated with biological growths and corrosion which could affect heat transfer and MRI Chiller working efficiency.

MRI Chilled water loops must be checked yearly and treated to remove containment.

Regularly do check your chiller’s “Y” strainer and utilize an inline cartridge filter for extra protection.

The light must be visible through the condenser coil for dirty particles.

Coils should be checked deep down with a flashlight and if dirt particles are found, do clean them.

Before starting cleaning always disconnect the power first and protect all electrical parts from water and water entering electrical conduit lines.

Monitor the Refrigerant Leaks: The level of cooling of an MRI Chiller is subject to the measure of refrigerant circulating through its compressor.

Valve stems and then vibrate loose and will cause refrigerant leaks. Refrigerant leaks from the compressor into the system can likewise affect the cooling capacity.

Checking of leaks and keeping an appropriate level of refrigerant in the MRI Chiller’s compressor unit will guarantee ideal performance.

Monitoring MRI Chiller Refrigerant Leak

Measurement of the Glycol Concentration: Protection of MRI Chiller parts from freezing is a basic necessity, as freezing can happen from the outside ambient or inner system temperature.

The evaporator (or another heat exchanger) is the most powerless part to freezing, even during normal working operations.

The liquid entering the evaporator should be able to do going through without forming ice. Ice formation rapidly restricts the flow, bringing about more freezing and possible burst.

The chilled liquid needs to have a freeze point that is well below any temperature that an MRI Chiller is capable of cooling.

Keep Maintain Optimal Chilled Water Flow Rate: The ratio of the flow of chilled water should be maintained to ensure its cooling performance.

MRI Chiller needs somewhere in the range of 2.5 and 3 gallons per minute (GPM) per ton to provide productive heat exchange.

You will have a 10°F temperature exchange at 2.5 GPM per ton, and an 8°F temperature exchange at 3 GPM per ton, and this can give you extraordinary performance.

Check for Non-Condensable: Another major part of your MRI Chiller maintain is keeping air and humidity out of your MRI Chiller system.

As these components can reduce your MRI Chiller efficiency and increase energy consumption, it is imperatively significant that they are immediately cleaned from the condenser circulation.

Check Motors and Starting Mechanism: Routine sensor adjustment, chip control assessment, deep security checks for electrical connections, wiring, and switchgear, are suggested.

Furthermore, standard drive motor checks are needed to keep the MRI Chiller completely functional.

MRI Chiller Electrical Connection Checking

Install Variable Speed Drivers: MRI Chiller motors consume a huge amount of electricity when being used, which increases your operational cost.

The installation of variable frequency drives (VFDs) will provide energy savings. These VSDs will allow it to work normally even on emergency power generators.
