Place workflows so that transfers between zones are efficient (minimize cross-traffic).
Consider door placements, access paths, and loading/unloading proximity.
Tip 2: Choose Panel Thickness Wisely
Thicker panels reduce heat ingress, especially in freezer zones — ideal is 5″ or 6″, depending on span.
Use uniform thickness or vary thickness between cooler vs freezer sides as needed.
Ensure panels meet required flame spread / smoke development ratings (≤ 25 / ≤ 450) as used in their combos.
Tip 3: Ceiling & Roof Design Matters
Use a “lag down ceiling” (flat to wall) to reduce thermal bridging and leakage.
Factor in load for internal equipment, insulation, HVAC ducting, lighting, and defrost lines.
Tip 4: Plan for Proper Airflow & Separation
Prevent thermal bleed between the cool and freezer areas. Insulating headers or airlocks may be necessary.
Position evaporators and return/airflow to ensure uniform temperature in both zones.
Account for defrost cycles, fresh air infiltration, and sealing.
Tip 5: Permits, Drawings & Engineering Ahead of Time
Get architectural drawings, structural, and MEP engineering before permit submission.
International Coolers provides these services to streamline approvals.
Engage local inspectors early to avoid redesign late in the project.
Tip 6: Choose Qualified Installation & Insurance
Use licensed contractors experienced in cold storage installation
Ensure they carry general liability, workers’ compensation, and list you as additional insured, particularly for larger projects.
Check that warranties cover panels, doors, refrigeration systems, and workmanship.
Tip 7: Plan for Maintenance & Monitoring
Include remote temperature monitoring, alarms, and backup systems
Schedule preventive maintenance on compressors, fans, insulation, and door gaskets

Retrofitting Commercial Refrigeration Systems: A Primer
One of the biggest drains on energy consumption in foodservice is commercial refrigeration. So obviously commercial refrigeration can also become an operation’s biggest savings opportunity. How to do that is the question we’ll try to answer.
For most foodservice operations, switching out their entire refrigeration systems is a non-starter. It’s easy to make energy-saving decisions before equipment is actually installed in a facility. But for existing properties like chain restaurants or K-12 school nutrition programs, they are typically not in a position to switch out their entire refrigeration systems.
This doesn’t mean existing operations don’t have the potential to save, though. When you’ve decided to retrofit an existing refrigeration system there are many paths you can follow. One thing is certain you need a qualified and certified commercial refrigeration company to do the work correctly. Let’s take a look.
Retrofitting for Energy Efficiency
Sometimes the low hanging fruit might be enough to meet efficiency standards. Things like replacing old fluorescent lights with LED. Simply replacing flourescents with LEDs can save you 68-85% energy, they also emit less heat, thus reducing the refrigeration load.
Replacing old cooler or freezer doors with new ones and upgrading door gaskets are also key. These reduce cold air leakage because of better insulation, and are easy fixes for many. Installing newer, more modern compressors, fans and door fans can also help you reach your energy efficiency goals.
For more challenging energy concerns however, there are some new technologies that might help.
VSDs
A VSD, or Variable Speed Drive is a compenent used to control motor speed for compressors and fans. Retrofitting a commercial refrigeration system with VSDs involves adding a VSD to an existing motor to adjust its speed based. Traditional HVAC systems operate at fixed speeds, VSDs however allow motors to operate at varying speeds, which significantly saves energy and reduces operating costs.
LED Lighting
Upgrading to LEDs with smart controls (occupancy sensors) to reduce heat load and energy use. LEDs use much less electrity and therefore generate less heat, meaning less work for your compressor.
LED lights also have a longer lifespan. An LED light lasts over 50k hours while the traditional flourescents only 7 to 15k hours. LEDs are more resistant and robust than flourescents. They can handle moisture and vibration much more readily that the traditional floursescents.
Install Electronically Commutated (EC) motors and Variable Frequency Drives (VFDs) on evaporator/condenser fans to match output to demand.
A Variable Frequency Drive (VFD) adjusts the electrical frequency to slow down motors when less cooling is needed. Using them can reduce electricity costs, often 30-50%, by matching output to actual demand. You will also end up with a more quiet operation since they reduce vibration as well.
These measures reduce utility charges at peak hours and reduce cycling for smoohter operatoin and less wear and tear on compressors and fans.
Replacing Doors and Covers
Add doors or night covers to open display cases to drastically cut energy loss. This can dramatically cut energy use by 20-75%. It does this by preventing cold air loss, improving food safety, reducing system strain. Another benefit is creating better customer comfort, as less of that cold air escapes thus creating a ‘cold aisle’ in your store.
Upgrade Compressors
Retrofitting commercial refrigeration with digital compressors can boost efficiency by enabling variable capacity. The variable capacity, precisely matching cooling to demand, reduces energy waste from constant on/off cycling. This can improve temperature control, often achieving significant savings.
Retrofitting commercial refrigeration with digital compressors boosts efficiency by enabling variable capacity. This is done toprecisely match cooling to demand, reducing energy waste from constant on/off cycling, and improving temperature control, often achieving significant savings
Another option is floating head pressure (FHP), which can significantly cutting compressor load and energy use by up to 15-45%. It does this by controlling condenser fans and using advanced controls like EEVs (Electronic Expansion Valves) and LPA (Liquid Pressure Amplifiers), boosting efficiency by letting head pressure drop with ambient temperatures.
Other Options
Refrigerants: Transition to lower Global Warming Potential (GWP) refrigerants. This involves switching to natural refrigerants (like CO2, ammonia, propane) or low-GWP blends (HFOs/HFCs).
Insulation & Gaskets: Improve door seals, insulation, and minimize air infiltration to prevent cold air loss and heat gain.
Controls: Upgrade to electronic controls, advanced sensors, smart thermostats, and occupancy sensors to optimize operation and reduce runtimes.
The Cost
Retrofitting commercial refrigeration for efficiency involves costs for equipment, labor, and potential electrical/piping work, ranging from thousands for smaller upgrades (like VSDs or controls) to tens of thousands or more for major component replacements or chiller retrofits, with typical project costs for larger systems often 10-20% of a new install’s price but yielding significant energy savings (3-7 year payback common) through options like Variable Speed Drives (VSDs), smarter controls, and component upgrades, according to sources like Consulting – Specifying Engineer and R&R Refrigeration.
Smaller upgrades might cost potentially a few thousand dollars, focusing on precise adjustments. Costs for swapping out compressors and fans, etc, etc., can vary, but retrofitting part is is often the lower cost alternative to buying a new unit.
Major retrofits can range from $15,000 to over $50,000. This range depends on whether you need new equipment with major chiller retrofits potentially reaching $500,000+.

Compute Express Link (CXL): This standard allows for flexible memory expansion and more efficient resource utilization, improving performance for AI workloads.
How tradional cooling methods and new cooling methods meet
For AI data centers, the future of cooling lies in a hybrid approach that strategically combines traditional air cooling with more efficient liquid cooling technologies.
Hybrid cooling combines air and liquid cooling to achieve better performance, efficiency, and sustainability than using either method alone. This approach is essential for managing the heat produced by high-density workloads seen in AI and high-performance computing. Hybrid systems offer flexibility, letting operators adapt by using liquid cooling for high-density servers and traditional air cooling for less intensive equipment or to manage internal heat transfer within the facility.
Hybrid cooling strategy: Facilities often combine traditional air circulation and aisle containment with liquid cooling solutions to create a multi-layered system. In this model, liquid cooling targets the hottest components, and air cooling manages the remaining ambient heat.
Rear-door heat exchangers (RDHX): These are commonly used liquid-cooled heat exchangers placed at the back of server racks. They remove heat as it exits the server, preventing it from entering the data center air. These can be used alongside existing air-cooling systems, allowing higher densities without major infrastructure changes.
In-row cooling: These units are placed between server racks and provide more targeted cooling than traditional CRAC units. They help manage heat from lower-density equipment that doesn’t require liquid cooling.
Partial liquid cooling: In this setup, a liquid-cooled loop is used specifically to cool the hottest components, while air cooling is used to remove the remaining heat from the rest of the system.
The future is up for grabs
These various techniques are being used in different combinations, and each situation is unique.
The success or failure of these combined systems will help determine the path forward. Currently, there is no single solution that works for all scenarios.

How to Protect Your Walk-In Coolers and Walk-In Freezers
Natural disasters, like hurricanes, floods, or tornadoes, can be overwhelming to respond to, and present several challenges. The retail grocery industry relies on top-tier commercial refrigeration repair and replacement to keep inventory fresh when these crisis occur. Emergencies such as power outages, electrical issues, and natural disasters can lead to closures for unspecified durations of time.
Natural disasters pose significant risks not only to people but also to critical equipment supporting our food chain, such as commercial walk-in coolers and freezers. This blog focuses on essential steps to address walk-in coolers and freezers after a natural disaster.
Prioritizing customer and employee safety is crucial in any dangerous situation. If a walk-in cooler or freezer suffers damage, follow a series of steps to salvage it whenever possible. However, severe damage may make some units beyond repair. When walk-in coolers and freezers are salvageable, taking the right steps can prevent further damage and preserve these essential systems.
Walk-in Freezers Present Extra Challenges
Walk in freezers often face more challenges than walk in coolers due to their need for lower temperatures. After a power outage, the door heaters in a walk-in freezer can overheat if the freezer hasn’t reached its required low temperature. To prevent this, turn off both the refrigeration unit and door heater circuits. If the door heater circuits stay on without an active refrigeration system, the extreme heat can lead to a fire risk.
Some General Guidelines for Dealing with Power Outages
When your walk-in cooler or freezer loses electricity, immediately remove all perishable food products. If left inside, the products will spoil, and bacteria from thawing items can seep into walls and floor joints, causing further damage to the unit.
Remove all perishable food products as soon as power is lost or as soon as possible. Product spoilage is the most obvious issue, however bacteria produced by thawing can seep into walls and floor joints, further damaging your commercial refrigeration unit.
Drain or mop up any water on the floor and wipe down any wall with excess water. Issues with bacteria are the concern here, but also staining and oxidization can also occur.
Air out your walk-in freezer or walk-in cooler by opening all doors to promote air flow.
Evaluate your commercial refrigeration unit for signs of damage. Door mis-alignment, joint separation, large surface dents or tears, uneven flooring, damaged strip curtains or anything that looks visible broken. You may consider bringing in a qualified professional to inspect your cooler or freezer at a deeper level.
Before turning your commercial refrigeration unit back on, you should measure the moisture content to ensure there is no moisture left in your cooler or freezer. Should your unit be turned on with moisture in the floor or walls can cause further damage. An extended draw-down period will also help eliminate moisture.
Some General Guidelines Without Electrical Outages
While dealing with a natural disaster that does not include an electrical outage is less intensive, there are still several steps you should follow:
Inspect your commercial refrigeration unit to ensure it is holding temperature. If the unit is not holding correct temperature, remove all products from the walk-in and dispose of them to ensure safety. Perishable products could have warmed up to the point of growing bacteria, making them dangerous to consume.
The second step is to evaluate and inspect the damage that has been done to the walk-in freezer. Sometimes you might need a trained professional to more closely evaluate potential damage, and plot a course forward.
If severe exterior damage has occurred, water from the natural disaster can leak into the walk-in cooler and freezer. Furthermore, moisture can also accumulate simply from an internal temperature drop. If this happens, dry the unit out as best as possible. Do this by mopping and wiping all surfaces as well as propping open the door for improved airflow. If possible also use fans to aid in the drying process.
Lastly we suggest examining the moisture content inside the unit. If moisture remains even after the previous step, you can use the refrigeration unit to pull the moisture and humidity out. An extended draw-down schedule will use the refrigeration unit to draw the moisture content and humidity out of the unit and create the perfect restored environment.

Another challenge is temperature consistency, which is critical for preserving perishable goods. Even slight fluctuations in temperature can result in spoiled inventory, especially in industries like food and pharmaceuticals, where safety is paramount.
Compliance with environmental regulations also poses difficulties, as refrigerants used in these systems are often subject to strict government standards. Businesses must ensure their systems meet the latest environmental guidelines to avoid penalties.
Finally, equipment longevity is another concern. Commercial refrigeration units are expensive investments, and businesses face the challenge of maximizing the lifespan of their equipment while ensuring optimal performance. Regular maintenance, monitoring, and timely repairs are essential to overcoming these challenges and maintaining efficient, reliable refrigeration systems.
Replacing commercial refrigeration systems
Replacing commercial refrigeration systems involves a multi-step process that requires careful planning and execution to ensure minimal disruption to business operations. The first step is assessing the current system. Businesses should evaluate their refrigeration needs, considering factors like capacity, energy efficiency, and temperature control. This helps determine whether an upgrade or a full replacement is necessary.
Next, the business selects a suitable replacement unit. Factors such as energy consumption, size, refrigerant type, and regulatory compliance should be considered. It’s crucial to choose a system that meets the business’s current needs while allowing for future growth.
Once a unit is selected, the removal of the old equipment takes place. This step involves safely disconnecting and disposing of the old system, following environmental guidelines for refrigerant disposal.
The installation of the new refrigeration system requires professional technicians to handle the electrical connections, refrigerant charging, and ensuring that the unit is properly calibrated for optimal performance.
Finally, testing and calibration are essential to ensure the new system operates efficiently, maintains consistent temperatures, and meets energy efficiency goals. Ongoing maintenance and monitoring are recommended to maximize the lifespan of the new system and avoid potential issues.
