What is the Difference Between Open Loop and in Line MRI Chiller?

There are most commonly two types of an MRI Chiller which comprises of the Open Loop MRI Chiller and the In-Line MRI Chiller

An Open Loop MRI Chiller work by using continuous and constant fluid flow and circulation.

A significant point about it is that they mostly use water in place of air for providing a cooling effect.

An In-Line MRI Chiller contains an internal evaporator which provides a cooling effect to the circulating fluid.

It also comprises a pump that creates a connection between the under operation fluid and a remote tank.

What is the Most Suitable Compressor for an MRI Chiller?

You have a variety of compressor options that can be used in an MRI Chiller.

The basic working is similar for all the compressors, but still, the addition and omission of various features mark the difference between every type.

However, the compressor that works best for it, is the scroll compressor.

The biggest advantage of using the scroll compressors is that they result in minimum noise from your device, which is very convenient for the user.

Moreover, there is very little disturbance produced during the entire cooling process in case this compressor is used.

What is the Difference Between Water Cooled MRI Chiller and Air Cooled MRI Chiller?

The main difference between a Water-Cooled MRI Chiller and an Air-Cooled MRI Chiller is the main component that is completing the whole cooling process.

The Water-Cooled MRI Chiller uses water for getting rid of the extra heat from the machine.

It is mostly placed internally in a special room and makes sure that constant water supply is an essential factor here.

An Air-Cooled MRI Chiller uses air for controlling the temperature of the fluids.

You have to place it outside any room where there is a constant supply of fresh air.
