Designated Water Cooled Chillers Can Save MRI Machines

By | Chillers

The images that MRI machines produce can oftentimes save lives. So, it goes without saying that MRI machines need to be accurate in order to be effective in treating and diagnosing patients. However, in order to work precisely and reliably, MRI machines need to maintain a certain temperature. Also, an overheating MRI machine can cause irreversible and costly damage to the machine itself. Having designated water cooled chillers is the best way to keep your MRI machines working perfectly.

Your MRI’s Internal Cooling System Needs HelpCarrier 550 ton chiller

MRI machines need to be relatively cool to be accurate and reliable. Seems simple enough, right? But there is a paradox in this equation, MRI machines run very hot, due to the electricity, magnetic pull and residual motion of the magnets.

MRI Machines have their own means of cooling, but it often isn’t enough. Here is how the process works. A helium-filled compressor called a cryocooler cools the magnet in the center of the machine. There are several layers of coils and heat exchangers that cool the cryocooler even more. However, if liquid helium were to leak out, the MRI machine could overheat, which could cause significant damage to the machine, not to mention a situation like this could delay treatment for patients or overload other MRI machines in the facility or hospital. This kind of loss or delay can cost a facility millions and may cost patients their lives.

Designated Water Cooled Chillers Will Save Your MRI Machines

A designated chiller can save your MRI machine, because it acts as a buffer between the MRI’s internal cooling system and anything that could possibly go wrong with it. When liquid hellion leaks, overheats or vaporizes, the designated water cooled chiller can cool your MRI machine enough to mitigate any damage, saving your facility millions.

The Cooler The MRI Machine, The More Accurate It Is

When patients go for an MRI, they have the right to reliable, accurate results. The cooler the MRI machine runs, the more accurate the imaging is. If an MRI overheats or produces an unreliable image, it could delay a patient’s treatment and diagnosis. Some patients who have urgent, life-threatening conditions, like heart attacks, car accident trauma or strokes don’t have the time to spare to get multiple MRIs. They need accurate and immediate imaging to assess the extent of their injury or illness. A designated water cooled chiller can assure that your MRI machine is operating at the most optimal temperature at all times, ensuring that your patients get the lifesaving results they need the first time.

The Right Cooling Tower Components Can Help You Manage Ice Buildup

By | Chillers

There’s nothing you can do about ice buildup on your cooling towers. There’s also nothing you can do to avoid icy cooling towers and chillers. Although you cannot prevent the ice, you can manage it better by choosing the right kind of cooling tower components.

Choosing The Right Components Matters500 Ton Marley Cooling Towers

Certain cooling tower components manage ice better than others. Here are some of the cooling tower components that will help you to manage icy weather better.

Choose Induced Draft Cooling Towers Over Forced Draft

Induced draft cooling towers control ice better than forced draft cooling towers because it has a fairly efficient deicing sequence. If ice does form, it runs the axial fan in reverse at half speed in short bursts to minimize the buildup.

Choose A Counter Flow Over Cross Flow

When you compare cross flow technology and counter flow technology, counter flow has the winter weather advantage. It provides a layer of protection from the winter weather, because the heat transfer media in counter flow towers is totally encased within the unit. Cross flow towers have fewer cooling temperature gradient throughout the heat transfer media, whereas counter flow has more, so the water is cooled at a more even rate, which prevents pockets of water from causing condensation and freezing.

Choose VFD Controls Over Two Speed Fan Motors

It’s important to keep the water at an above freezing temperature of about 42°F. Using variable frequency drive controls or VFD controls is the most efficient and flexible capacity control method. The two-speed motor does work reasonably well, but it’s not as efficient.

Choose A Multiple Cell Over A Single Cell

Many cooling systems are designed to run on reduced water in the winter to accommodate the lower heat load in the winter. Water can be diverted from one cell to another, which can mediate uneven eater distribution. Uneven water distribution is more prone to freezing and ice production.

Does The Winter Weather Make You Worry About Your Cooling Towers?

Does the winter weather make you worry about how you’ll manage the ice and snow on your cooling towers? Just making a few adjustments to the components of your cooling tower can save you so much time in the future.
