Medical Cooling: MRI, CT, PET, Linac
Why medical imaging equipment requires cooling
Without proper cooling for a medical imaging device, image quality can degrade, system calibration may drift, downtimes may increase, sensitive components can fail prematurely, and facilities risk cost-effective service interruptions. A properly sized system chiller promises constant heat removal, protecting not only the equipment performance but also a steady workflow with no interruptions.

Medical Cooling Applications
- MRI systems
- Linear accelerators (LINAC)
- CT machine cooling
- PET scanners
- X-ray imaging systems
- Radiation therapy equipment
Each of these systems has it’s own unique flow rate, pressure, and temperature range requirements. That’s why our chillers are fully customizable to fit any application.
Air-cooled vs Water-cooled chillers for healthcare facilities
Air-Cooled Chillers
- Smaller Imaging Centers
- Facilities without cooling towers
- Retrofit installations
- Rooftop or outdoor installations
Air-cooled chillers do not have as large of cooling capacity as water-cooled chillers. However, they make up for it with easier isntallation, low maintenance, all while still being reliable.
Water-Cooled Chillers
- Large hospitals
- Multiple imaging areas/rooms
- High-capacity systems
- Central indoor located unit
Offer higher efficiency in high intensity environments and integrate well into existing building mechanical systems.
Key Cooling requirements for medical imaging applications
When selecting a chiller for MRI or CT equipment, several technical factors must be carefully evaluated:
1. Temperature stability
Imaging equipment requires a tight and consistant temperature control. Maintaining a proper operating temperature protects equipment and prevents stress over extended periods of use.
2. Continuous operation
Hospitals or other high traffic facilities may run medical imaging machines 24/7, making Legacy Chillers reliable, low maintencance units essential for your operation.
3. Precise flow control
Improper flow rates can trigger machine alarms or damage components. Our chillers are engineered to match imaging manufacturer specifications. Some medical imaging manufacturer brands include Toshiba, GE, Siemens, and Philips.
4. Quiet Operation
Imaging suites require low noise levels to maintain a comfortable patient environment. Making split-system units with an putdoor condenser, or a centrally located water cooled chiller.
5. Compact footprint
Mechanical rooms in hospitals are often tight, our space-efficient desings help simplify installation.
How medical imaging chillers improve equipment longevity
Proper cooling does more than prevent overheating – it extends the lifespan of mission critical components
By maintaining stable operatin temperatures, chillers help:
- Reduce thermal expansion stress
- Protect high-voltage electronics
- Minimize wear on power modules
- Maintain imaging accuracy
- Reduce unplanned service calls
In high revenue imaging environments, preventing any downtime can justify trusting Legacy Chillers to engineer the perfect cooling system for you.
