DAILY/MONTHLY TEMPERATURE LOG
Curious where your state ranks in average energy costs?
As we roll through the dog days of summer, air conditioners are working hard everywhere, and businesses with refrigeration systems are scrimping pennies to battle the heat to maintain temperature in their cold spaces. Whether the walk-in coolers (or freezers) are storing soft drinks, fresh produce, or frozen proteins, specific
Historically Cold Climate can Wreak Havoc on Air-Cooled Condensing Units
The historically cold temperatures gripping a lot of the country right now are not detrimental only to you, and your home heating bill; they are also increasing the likelihood of an operational issue in air-cooled condensing units. The use of low pressure refrigeration controls (LPC) is mostly found in smaller,

In this new weekly blog series, NRM will highlight an issue a customer had and was able to resolve with our industry-leading control and monitoring solutions. Some of the most serious refrigeration problems can go undetected and result in equipment failures and/or product loss. Problem of the Week: Pesky Solenoid Valve is
Compressor Short Cycling: A Hard-to-Find Energy Waster
In commercial applications, one of the most important tasks in keeping components running at their peak performance is determining what’s a cause and what’s a symptom if mechanical problems arise. The difference between knowing and not knowing could be thousands of dollars worth of diagnosis. In particular, short cycling seems
Coolers/Freezers and Energy Efficiency 101: Lighting Impact on Refrigerated Load Savings
In part one of this blog series, we sough to break down the various terms and descriptions for the sub-sections of what’s known as refrigerated space. In part two, we described the different lighting technologies commonly used in refrigerated spaces and compared them with more efficient LEDs. In part three today,
The Future of HVACR Energy Efficiency: Monitoring-Based Commissioning
Monitoring-Based Commissioning (MBCx) is getting a lot of attention these days in the energy efficiency field. Why? Simply put, to save money in energy usage and maintenance costs of HVAC, refrigeration, Chiller, and other types of equipment utilized by office, commercial, institutional and industrial buildings. For those of you who
Where’s the Most Expensive Ice in the World? On Your Evaporator Coils
We all know ice is great; it’s cheap, can be bought in bulk, and cools most things that we can think of that need to be cooled. But there are several kinds of undesirable ice that end up costing a lot for operating refrigeration equipment in commercial and industrial coolers and freezers. This
NRM is Proud to Play a Role in the Dunkin’ Brands, National Grid, and Eversource Energy Management Program
The energy management program, available to Dunkin’ Brands franchise owners, seeks to identify opportunities to improve the energy management capabilities of DD locations. It addresses whole building energy savings, while providing insight into building operations and system controls, with the goal of reducing overall operating costs and encouraging investments to
