MRI Chillers > Medical MRI chiller solutions
If you are upgrading, replacing or planning a new GE or Siemens
MRI scan system, Legacy Chillers has MRI chiller cooling solutions
available for GE and Siemens. Our pre-engineered MRI chiller
solutions are designed for the most demanding scanning
environments. If you are also in need of engineering, or
installation services, Legacy has the skills and resources to help
ensure a successful turnkey project in all major U.S. markets.
A typical MRI resembles a large donut in many ways. There is a
small hole in the center of the MRI where the patient slips into.
The outer ring of the MRI is a large super conducting magnet. Our
bodies consist of millions and millions of cells, and these cells
have different densities and makeup. As a body enters the MRI's
magnetic field, each cell reacts differently to this magnetic
field. Using advanced software and super computers, the MRI's can
now distinguish these cells from one another on a molecular level
and map your specific organs into digital images. Once the image
is captured the MRI now has the capability to rotate and slice a
section of the image in a variety of ways.
Key to the efficiency and ability of any MRI is the huge
superconducting magnet within the MRI's outer ring. To reach
maximum performance these magnets must be cooled down to -200 to
-600c. To accomplish this, liquid helium is commonly used as a
refrigerant. In order to maintain the liquid helium cooling
system, a water-cooled gradient compressor needs to be used, and
this is where Legacy Chiller Systems comes in. Our chiller systems
are designed to provide top-rate efficiency, with you the customer
in mind.
There are two types of Mri Chillers:
Air-cooled chillers and
Water-Cooled Chillers
What is the difference between an air cooled chiller and a
water chiller?
These two terms have to do with how the chillers refrigeration
system gets rid of the heat it removed from the water process
loop. In the case of an air-cooled chiller, heat is rejected to
the ambient air. In the case of a water-cooled chiller, heat is
rejected to some other water source such as a cooling tower plant
chilled water system.
Why would you purchase an air cooled chiller?
If the facility does not have a ready water source such as a
cooling tower or plant chilled water system, an air-cooled chiller
is the way to go. The chiller itself is a little more expensive.
However, with respect to the total system, it is much less because
you don't need anything else to carry the heat off other than air.
Why would you purchase a water cooled chiller?
If the facility does have a ready water source such as a cooling
tower or plant chilled water system, then a water-cooled chiller
is the way to go, provided that the existing water system has
enough reserve capacity to service the additional head the chiller
will put in to the system.
