4 Reasons Why Chillers Are Used In Medical Equipment

Like any other heavy equipment, some medical equipment also requires maintaining a cool temperature to function efficiently. This is why medical chillers are needed to remove the medical equipment's heat when they operate. With the help of these chillers, the machine can continue to operate without being shut down to cool off its system.

Medical Equipment That Requires Chillers

MRI Machines

The MRI machines have a magnet inside that heats up and needs to be cooled down to operate efficiently. So air or water-cooled medical chillers are installed in the MRI machines. If the air-cooled chiller is used, it will transfer the heat from the equipment to the surrounding air. These are ideal for facilities that do not have a nearby water source.

On the other hand, water-cooled chillers transfer the heat to a water source such as a cooling tower or plant chilled water system.

CT Scans

The X-ray tube in the CT scanners gets heat up without a chiller requiring around 10 to 30 minutes to cool down. The time consumed in cooling delays patient care, in turn increasing medical costs. Installing a medical chiller would mean that the CT scanner can operate continuously and more efficiently, allowing it to help more patients.

PET Scans

PET scanners are used to produce 3D images of body processes, making the equipment generate a lot of heat. Hence, like other heavy-duty medical equipment, the PET scanner requires a cooling system too. Medical chillers come in as saviours to help them continuously operate for long periods.

Oncology Linear Accelerators

With the help of electromagnetic waves, these machines produce X-rays that accelerate charged particles. Unfortunately, like CT scans, the X-ray tube in this equipment also generates an incredible amount of heat. So using a chiller, this heat can be eliminated from the machine and ensure smooth operation.

Types Of Medical Chillers

Open Loop Chillers

These types of medical chillers circulate a liquid continuously to maintain the temperature of the equipment. A water source is often used in these chillers instead of air for cooling. This helps keep the size of the chillers reduced and allow less energy consumption because the chiller has a water-based condenser that takes a small surface area with no fan. This makes them a lot less noisy and efficient, turning out to be a great cooling system for CT scans, MRI machines, and pharmaceutical processing applications.

In-Line Chillers

In-line chillers have an evaporator inside, which cools down passing fluid under pressure. A remote tank maintains the liquid flow, and a pump circulates this fluid near the tank. These pumps can be of great use to CT scan machines.

Drop-In Coolers

An evaporator coil is surrounded by cool fluid in these chillers, which sit on top of a tank. The evaporator coil is of stainless steel, which submerges into the tank, and the fluid is circulated with an agitation pump around the evaporator coil and provides proper cooling throughout. The fluid's temperature is monitored and controlled by a controller to maintain the temperature.

Closed-Loop Coolers

The coolant is circulated from a tank inside the cooler. A sealed coolant loop moves the coolant and spindles it before sending it back to the tank. The coolant carries the heat is dissipated in an evaporator before the coolant returns to the tank. A temperature controller controls the evaporator to ensure the desired temperature of the coolant. These types of coolers are ideal for x-ray machines, PET scans, and linear accelerators.


Chillers can be a very efficient piece of equipment for medical facilities as they have to operate their machines all day to ensure a continuous service. In addition, it will keep the medical equipment cool and prevent them from heating up and malfunctioning.

So if you're using heavy equipment at your medical facility, you must get a cooling system for it to ensure an extended lifespan.
