“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 […]
The reason for the powerful heaters on most reach-in cooler and freezer doors is to prevent fog or condensation on them. When the glass in those doors becomes fogged, the products behind are less visible to the customer, so either the store loses sales or customers open more doors for longer times to better see […]
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 […]
The evaporator fans inside your commercial walk-in cooler or freezer are probably running right now. In fact, they probably run all the time, spinning 24/7/365, delivering cold air to keep your store’s valuable foods and beverages safely and reliably refrigerated. Did you know there are many significant ways to save lots of energy, money and […]
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 […]
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 […]
The last thing that you want is to walk into your cooler and find a block of ice in place of your evaporator. Here are some tips to help you keep your system working as efficiently as possible.
- Use skilled technicians. Before any maintenance is even required. Be sure that all new equipment is installed […]
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.
