A Comprehensive Approach to Refrigeration Efficiency

“Later” can become never. If some energy-saving opportunities are saved for another day, it is likely that simple inertia will prevent that day from ever coming at all.  Moreover, those lost days are savings that are lost forever.  Everyone involved, from the business owners, the installing contractors,  to the rebating authorities, should have an interest in […]

Do Door Heaters Need to Run All the Time?

The reason for the powerful heaters on most reach-in cooler and freezer doors is to prevent fog or condensation on them.

Will Switching Off the Evaporators Waste Energy?

Turning off the evaporator fans after the compressor is switched off does not waste the thermal inertia (the “cold”) inside the evaporator coils. Once the refrigerant inside the evaporator coils is evaporated and returned to the compressor, which takes just a few seconds, the cold remains in the evaporator. The walk-in cooler itself is as […]

What’s the Difference Between Electrical Demand and Electrical Usage?

Sometimes it seems like your electric bill is designed to make it hard for you to know how it is calculated. With charges for generation, transmission, transition, distribution, demand, energy efficiency, renewable energy, and just for being a customer, you might think that you just aren’t supposed to understand it. However, almost all […]

How Much Money Can I Save with Freeaire®?

Although a Freeaire® All Climate™ system will generally save 30-50% of the cost to cool a walk-in cooler, freezer or refrigerated warehouse, the best answer to this question is “It depends.” A Freeaire® All Climate™ system includes a number of energy efficiency measures, each of which depends on a variety of factors that affect the amount […]

How Often Do My Evaporator Fans Need to Run?

Walk-in cooler owners have often asked if it is really a good idea to switch off the evaporator fans inside their coolers.  Intelligently shutting down your evaporators does not compromise the system’s ability to keep the cooler at the desired temperature, nor does it create potential to damage the compressor system.
