Walk-In Cooler Applications

A walk-in cooler is just what it sounds like: a cooler you walk into. To maintain a cool temperature, these units are fully enclosed with insulated walls, floors, and ceilings. You’ll find them in convenience and grocery stores, restaurants, hotels, florists, and more—any building that requires safe food and beverage storage on an industrial scale.

Walk-in coolers have an evaporator on the unit’s interior and a condenser on the exterior. These components work together to transfer heat outside and keep cool air inside. The insulation means the evaporator and condenser don’t have to work as hard to keep the temperature cool, which reduces utility costs.

Why Your Walk-In Cooler’s Power Supply Matters

Walk-in coolers need a reliable power supply to keep food and beverages at safe temperatures for consumption. A compressor of around .5hp is the typical power requirement for an industrial walk-in cooler, and around 1 hp for a walk-in freezer. Here’s why having an adequate power supply matters.

Maintaining Temperature

Walk-in coolers keep perishable goods, such as food and pharmaceuticals, at specific temperatures to prevent spoilage and maintain product safety. A consistent and proper power supply is essential to ensure that these desired temperatures are consistently maintained. Fluctuations or power outages can lead to temperature variations that jeopardize the quality, freshness, and safety of stored products.

Food Safety

In commercial kitchens, restaurants, grocery stores, and food service operations, maintaining the cold chain is critical to ensuring food safety. Improper power supply can compromise this chain and increase the risk of foodborne illnesses due to temperature deviations. Walk-in coolers are designed to keep perishable goods, such as food and pharmaceuticals, at specific temperatures to prevent spoilage and maintain product safety.

Energy Efficiency

Walk-in coolers are energy-intensive appliances. Having the right power supply ensures they operate at peak efficiency, which is better for the environment and your wallet. It’s actually cheaper to power one industrial walk-in cooler than it is to power multiple standard refrigerators because walk-in coolers are more powerful and operate more efficiently. In contrast, inadequate or unstable power can result in an overworked cooling system, which requires higher energy consumption.

Business Operations

For businesses that rely heavily on walk-in coolers, such as restaurants, breweries, grocery stores, and pharmaceutical manufacturers, power disruptions can interrupt business operations. These interruptions increase downtime, reduce productivity, and hurt your bottom line.

Using Three-Phase Power for a Walk-In Cooler

How Three-Phase Power Works

Three-phase power is a form of electrical power distribution that uses three alternating currents—also called phases—of electricity. It’s commonly used in industrial and commercial applications, including the operation of walk-in coolers and freezers in the food service and pharmaceutical industries.

The three-phase electrical supply is connected to the cooler's compressor, a central component of the cooling process. Three-phase power ensures the motor that drives the compressor runs smoothly, providing a steady power supply from start to finish.

Benefits of Using a Phase Converter

  1. Enhanced Energy Efficiency: The three-phase power a phase converter provides improves energy efficiency by optimizing power consumption and reducing operational costs.
  2. Increased Equipment Lifespan: The consistent and balanced power provided by a phase converter extends the lifespan of walk-in cooler components by minimizing wear and tear.
  3. Cost Savings: Powering walk-in coolers with a phase converter not only reduces energy costs but also means you don’t have to upgrade your existing electrical system to accommodate a three-phase power supply.
