Energy-Saving Upgrades for Commercial Refrigeration Systems
For many business owners in Orem, Utah, the monthly utility bill is a constant reminder of the high cost of doing business. In restaurants, grocery stores, and cold storage facilities, refrigeration is often the single largest consumer of electricity. Unlike heating or cooling, which can be dialed back after business hours, commercial refrigeration must run twenty four hours a day, seven days a week, to protect inventory and ensure food safety. This constant demand makes refrigeration systems prime candidates for energy saving upgrades that can significantly impact the bottom line.
Technological advancements in the refrigeration industry have moved rapidly over the last decade. Many systems currently in use across the Wasatch Front were installed when energy was cheaper and efficiency standards were less stringent. Continuing to run an outdated or unoptimized system is essentially an ongoing financial drain. By investing in modern upgrades, business owners can reduce their energy consumption, lower their carbon footprint, and decrease the mechanical strain on their equipment, which leads to fewer emergency repairs and a longer lifespan for their units.
The goal of energy efficient upgrades is to achieve the same cooling results with less electrical input. This is accomplished by improving insulation, optimizing airflow, and utilizing more advanced motors and control systems. When a business in Orem works with the experts at Vortex Air, they can identify the specific areas where their refrigeration is wasting power and implement targeted solutions. These upgrades often pay for themselves through energy savings in a surprisingly short amount of time, making them one of the smartest investments a commercial operator can make.
High Efficiency Fan Motors
One of the most effective and common upgrades for commercial refrigeration systems is the replacement of old evaporator and condenser fan motors. Traditional systems often use shaded pole motors or permanent split capacitor motors. While these are reliable, they are notoriously inefficient, as they convert a large portion of the energy they consume into heat rather than mechanical movement. This is a double blow to efficiency because the refrigeration system then has to work even harder to remove the heat generated by its own fan motors.
Modern electronically commutated motors, often referred to as EC motors, are a vastly superior alternative. EC motors use permanent magnets and integrated electronics to control the motor’s speed and torque. They are significantly more efficient than older motor types, often reducing fan energy consumption by fifty to seventy percent. Because they run much cooler, they also reduce the heat load on the refrigerated space. In a walk in cooler or a large reach in display case, swapping out multiple old motors for EC models can lead to substantial and immediate savings on the monthly electric bill.
Beyond just raw efficiency, EC motors offer better control. Many of these motors can be programmed to run at variable speeds, allowing them to slow down when the compressor is not running or when the cooling demand is low. This further reduces energy waste and also creates a quieter environment for both staff and customers. For businesses in Orem looking for a high return on investment with minimal downtime during installation, upgrading to high efficiency fan motors is often the best place to start.
Advanced Refrigeration Controllers and Floating Head Pressure
Older refrigeration systems typically operate on a fixed setpoint. The compressor and fans run at a constant rate to maintain a specific temperature, regardless of the conditions outside the building. This “one size fits all” approach wastes a significant amount of energy, especially in a climate like Orem’s where temperatures fluctuate wildly between the heat of summer and the freezing nights of winter. Advanced refrigeration controllers can modernize these systems by introducing intelligence and adaptability into the cooling cycle.

One of the most impactful features of these modern controllers is the ability to implement floating head pressure. In traditional systems, the head pressure is kept artificially high to ensure the expansion valve functions correctly during hot weather. However, when the outdoor temperature drops, the system can actually run much more efficiently at a lower head pressure. A smart controller monitors the ambient outdoor temperature and automatically adjusts the head pressure to the lowest safe level. This reduces the workload on the compressor, which is the most energy hungry part of the system.
These controllers also optimize the defrost cycle. Many older units are set to defrost on a rigid timer, regardless of whether there is actually ice buildup on the coils. This wastes energy by heating up the evaporator unnecessarily and then requiring the system to cool back down. Smart controllers use sensors to detect ice buildup and only initiate a defrost cycle when it is actually needed. This “defrost on demand” approach saves energy and provides more stable temperatures for the stored products, which is a win for both the utility bill and food quality.
Door Gaskets and High Efficiency Hardware
The most efficient refrigeration system in the world will still waste money if the cold air is leaking out through the doors. For Orem businesses with walk in coolers or reach in cases, the integrity of the door seals is paramount. Over time, rubber gaskets become brittle, torn, or compressed, creating gaps that allow warm, humid air to enter the refrigerated space. This causes the compressor to run much longer than necessary and can lead to excessive ice buildup on the evaporator coils.
Regularly replacing worn door gaskets is one of the simplest and least expensive ways to improve efficiency. When a door seals tightly, the unit can maintain its setpoint with far less effort. In addition to gaskets, upgrading to high efficiency door hardware can make a big difference. Self closing hinges and automatic door closers ensure that doors are never accidentally left ajar by busy staff members. Even a door that is cracked open just an inch can cause a massive spike in energy consumption over the course of a day.
For businesses with open display cases, such as those found in grocery stores or deli sections, adding glass doors or plastic strip curtains is a game changer. Open cases are incredibly inefficient because they are constantly fighting to keep a curtain of cold air in place while ambient store air mixes with it. Installing high quality, anti fog glass doors can reduce the energy use of a display case by up to fifty percent. While it changes the aesthetic of the store, the financial and environmental benefits are too large to ignore for many modern operators.
LED Lighting Upgrades
Lighting is an essential part of commercial refrigeration, particularly in retail environments where product visibility drives sales. However, traditional fluorescent or incandescent bulbs are a major source of energy waste. Not only do these bulbs consume a significant amount of electricity, but they also generate a large amount of heat inside the refrigerated space. In a walk in cooler or a reach in display, the refrigeration system must then expend even more energy to remove the heat produced by the lights.

Upgrading to LED lighting is a simple and highly effective solution. LEDs consume a fraction of the power of traditional bulbs and produce very little heat. Because they are more durable and have a much longer lifespan, they also reduce the frequency of maintenance and the cost of replacement bulbs. In a cold environment, LEDs actually perform better than fluorescent bulbs, which often struggle to reach full brightness and can flicker when temperatures drop.
The aesthetic improvement of LEDs shouldn’t be overlooked either. They provide a crisp, clean light that makes products look more appealing to customers. Many LED systems for commercial refrigeration also feature motion sensors or dimming capabilities. This allows the lights to turn off or dim when no one is in the aisle, further reducing energy waste without sacrificing the customer experience. For an Orem business owner, this is an upgrade that improves both the look of the store and the health of the bank account.
Variable Frequency Drives for Compressors
The compressor is the heart of the refrigeration system and by far the largest consumer of energy. In most older commercial systems, the compressor is either one hundred percent on or completely off. This “bang bang” control method is inherently inefficient because the system often overshoots the target temperature and then has to wait for the temperature to rise before starting again. The high starting current required every time the compressor kicks on also adds to the electrical load.
Installing a Variable Frequency Drive, or VFD, allows the compressor to vary its speed based on the actual cooling demand. Instead of cycling on and off, the compressor can run at a lower, more consistent speed to maintain a precise temperature. This significantly reduces the total energy consumption and eliminates the frequent high current starts that can lead to electrical surcharges from the utility company. By running more steadily, the compressor also experiences less mechanical wear and tear, which extends its lifespan and improves system reliability.
VFDs are particularly effective for systems that experience varying loads throughout the day, such as a restaurant kitchen that is much hotter and busier during the lunch rush than it is in the afternoon. While the initial cost of a VFD is higher than some other upgrades, the long term savings are substantial. For large scale commercial operations in Orem, a VFD is often the most impactful upgrade available for reducing energy costs and improving the overall performance of the refrigeration infrastructure.
The high energy demand of commercial refrigeration doesn’t have to be a permanent drain on your Orem business. By implementing modern energy saving upgrades, you can take control of your utility costs and improve the reliability of your essential equipment.
