Why Choose a Legacy Chiller for your MRI/CT/Linac Cooling
MRI, CT, PET and Linac Process Chiller Statement of Value: Each of our fluid cooling systems are specifically designed to meet the 24/7/365 demands for medical process cooling. During production each built to order chiller undergoes rigorous quality control with extensive QC during and after final load testing.
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.
Healthcare Facilities require more than just cooling equipment – they require dependable performance and responsive support from a group of trusted individuals.
Legacy Chillers provides:
- Application-specific engineering
- Industrial-grade components
- High-efficiency compressor options
- Customizable controls
- Technical support
Our chillers are built for durability, stability, and long-term performance in mission-critical environments.

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.
Benefits of a Legacy Chiller
- Consistent product temperatures
- Reduced contamination risk
- Energy-efficient economizer designs
- Stainless component options
- FDA and A2L-compliant configurations
- Low global warming potential refrigerants R454A and R454C
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:
- Temperature stability
Imaging equipment requires a tight and consistent temperature control. Maintaining a proper operating temperature protects equipment and prevents stress over extended periods of use.
- Continuous operation
Hospitals or other high traffic facilities may run medical imaging machines 24/7, making Legacy Chillers reliable, low maintenance units essential for your operation.
- 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.
- Quiet Operation
Imaging suites require low noise levels to maintain a comfortable patient environment. Making split-system units with a outdoor condenser, or a centrally located water-cooled chiller.
- 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 operating 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.
Redundancy & reliability for critical healthcare environments
In medical facilities, downtime isn’t just inconvenient, it impacts patient care and daily operations
Legacy Chillers offers:
- Redundant pump configurations
- Backup compressor options
- Alarms and remote monitoring
- N + 1 system design options
- Custom controls and easy to use HMI display
For imaging centers running multiple MRI or CT systems, we design central chilled water systems to support multiple loads while maintaining precise temperature stability.
Custom chiller solutions for imaging OEM requirements
Strict cooling requirements are offered by numerous imaging manufacturers. We collaborate closely with equipment suppliers, contractors, and facility engineers to create systems that satisfy:
- Required flow rates
- Entering and leaving water temperatures
- Pressure requirements
- Glycol compatibility
- Electrical constraints
Our engineering team can assess your current setup and recommend a chiller that is the right size for your operation, whether you’re replacing an outdated cooling system or upgrading equipment.
