Choosing the Right Unit: Key Factors to Consider
Picking the perfect commercial refrigeration equipment is a strategic decision affecting your operations and budget. Consider the unit's size and capacity, fit within your kitchen layout, energy consumption, budget, and installation requirements like ventilation. Getting this right ensures smoother operations.
Key Considerations for Your Commercial Refrigeration Equipment
These practical details impact how a new unit performs in your kitchen.
Space and footprint: Measure the installation spot and the delivery path, including doorways. Account for door swings to avoid blocking walkways and ensure proper clearances for airflow and maintenance.
Interior capacity: Plan for future needs to avoid overstuffing, which impairs cooling and wastes energy. For door style, choose solid doors for insulation or glass doors for display. Features like self-closing and field-reversible doors add energy savings and flexibility.
Compressor location: A top-mounted compressor is better for dusty environments as it pulls cleaner air from above. Bottom-mounted compressors are easier to access for service. Caster mobility is essential if you need to move the unit for cleaning or rearranging.

Understanding Energy Efficiency and Costs
The sticker price is just the beginning; lifetime operating costs are substantial. Centralized refrigeration can account for 40-50% of a supermarket's energy use.
Look for ENERGY STAR ratings for proven efficiency. For walk-ins, check for compliance with AWEF (Annualized Walk-in Energy Factor) regulations. The industry is also shifting to natural refrigerants like R290 (Propane) and CO2 systems, which have a lower Global Warming Potential (GWP). R290 units can cut energy use by up to 40%, while CO2 systems offer 10-20% savings, benefiting both your budget and the planet.
Many new units also feature advanced energy-saving tech like DC-inverter cooling units and BLDC compressors that dramatically cut electricity usage. Some even offer waste heat recovery, using the heat generated by the fridge to warm water or your space. With rising electricity prices, focusing on low running costs is a smart move.

Budgeting and Financing Options
The upfront cost of commercial refrigeration equipment is a significant investment, but it's crucial to focus on long-term value. An energy-efficient unit may cost more initially, but it saves thousands on electricity bills over its lifespan.
Large equipment purchases can strain cash flow, which is why flexible financing is a game-changer. Our Rent-Try-Buy programs (for funding of $1,000+) offer a 12-month rental agreement to test equipment before committing. If you buy, you can get back 60% of your net rental payments towards the purchase, and payments are often 100% tax deductible.
We also offer lease-to-keep options to spread out costs without a large capital outlay. Through partners like SilverChef, businesses can get pre-approved for up to $40,000 in finance in as little as 10 minutes. These flexible options protect your cash flow and allow you to upgrade as your business evolves.
Keeping Your Cool: Maintenance and Troubleshooting
Even the best commercial refrigeration equipment needs regular care. Proactive maintenance is your secret weapon against costly breakdowns and spoiled food. Issues like slow cooling or temperature swings are signs that maintenance, troubleshooting, or a professional service call is needed.
Maintaining Your Commercial Refrigeration Equipment for Peak Performance
Like a car, your refrigeration equipment needs regular tune-ups. A little effort now prevents major issues and saves money later.
Keep your unit clean inside and out. Regular wipe-downs prevent odors and bacteria.
Clean the condenser coils every 3-4 months (or more often in dusty kitchens). Dirty coils make the compressor work harder, increasing energy bills and shortening the unit's life.
Check door seals (gaskets) for cracks or looseness. A poor seal lets cold air escape, forcing the unit to work overtime. Test the seal by closing a dollar bill in the door; if it pulls out easily, the gasket needs attention.
Ensure proper airflow by leaving at least six inches of clearance around the unit and keeping vents clear. Also, check for fan obstruction inside the unit; blocked evaporator fans prevent proper cooling.

Common Problems and How to Troubleshoot Them
A sluggish unit may not be a major problem. Here are common issues you can troubleshoot yourself:
Check thermostat settings. They can be changed by accident. Digital controls often use a "P" or set button, while older models may have a dial.
Avoid overloading with warm product. Most commercial refrigeration equipment is designed to hold cold food, not rapidly chill large batches of hot food. Cool hot items to room temperature first to avoid stressing the system.
High ambient temperature can be a culprit. If your unit is in direct sunlight or a very hot kitchen, it has to work much harder to stay cool.
Frequent door opening causes major temperature swings, forcing the unit to work harder to maintain its temperature.
Ensure each piece of commercial refrigeration equipment has its own dedicated circuit, ideally a 15-amp breaker, to prevent power fluctuations that can impair performance.
If these steps don't resolve the issue, it’s time to call a professional. For freezer-specific issues, see our guide: Fixing Common Issues with Imperial Frost-Free Commercial Freezers
Rules of the Chill: Navigating Regulations and Standards
Beyond keeping food cold, your commercial refrigeration equipment must comply with important rules. These include food safety standards, health codes, and energy regulations that protect public health and the environment.
Food Safety and Temperature Compliance
Food safety is paramount. Health departments mandate that cold foods be kept below 40°F (4°C) and frozen foods at 0°F (-18°C) or colder. This prevents food from entering the "danger zone" where harmful bacteria can grow.
Health inspectors verify compliance during regular visits. Non-compliant commercial refrigeration equipment can lead to fines, shutdowns, or even permanent closure.
To avoid issues, implement a temperature monitoring plan by regularly logging your unit's temperatures. This is a key part of any HACCP (Hazard Analysis and Critical Control Points) plan for food safety.
Look for certifications like NSF International (NSF) for public health and sanitation safety, and Underwriters Laboratories (UL) for electrical safety. These certifications are crucial.
Energy and Environmental Standards
Energy and environmental standards aim to reduce electricity consumption and environmental impact, especially for commercial refrigeration equipment.
The Department of Energy (DOE) sets efficiency rules for refrigeration units. For walk-in coolers and freezers, the AWEF (Annualized Walk-in Energy Factor) standard measures energy efficiency, pushing manufacturers to create greener products.
A major change is the shift from HFC refrigerants, which have a high Global Warming Potential (GWP). The industry is moving to natural refrigerants like R290 (Propane) and CO2. These are better for the environment and can significantly reduce energy bills.
