Oil-Filled Temperature Sensors for HVACR 101
Oil-filled temperature sensors are one of three, general sensor options along with electronic or gas-filled. Oil-filled may be worth considering if, for example, you wanted to track something like the internal temperature of stored product. This blog post introduces oil-filled temperature sensors. In refrigeration applications, most temperature sensors, of any design type, electronic or gas-filled, are […]
Liquid Subcooling: What it is and When to Apply it
Subcooling is often a lightly understood practice for new HVACR technicians entering the field. This blog post seeks to outline what it is, why it’s useful, and some of its best practices. In most cases, a new-to-the-field HVACR technician can tell you, in general terms, what liquid subcooling is. Perhaps even what it does, or […]
HVACR Contractors: the Key to a Healthy Relationship with Your Customers? Communication
In the relationship between HVACR contractors and their customers who rely on the complex, expensive refrigeration equipment to keep their business alive, neither partner has it easier than the other. Especially when that relationship exists in the restaurant and service industry. Both restaurateurs and contractors work long, hard hours, maintain operation no matter the weather, […]
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, refrigerated boxes such as beer […]
Hey, HVACR Contractors, Here Are 5 Ways Smart Controls Can Improve Your Client Relationships
The majority of our blog posts are crafted with a general audience in mind. Those seeking to learn more information about energy efficiency, the operation and energy consumption of their commercial or industrial refrigeration equipment, how those systems tie into their operations management, as well as general trouble-shooting or maintenance tips. These types of posts […]
Evaporator Fan Cycling: Is it Really a Risk?
In most walk-in coolers and freezers, the evaporator fans run 24 hours a day, 365 days a year, at full speed. Those fans are not only consuming energy the whole time, they are also generating heat, and the constant swirling of the air picks up even more heat from surrounding lights, walls, open doors, and […]
2018 E. Coli Outbreak can be Learning Opportunity for Leafy Greens Industry
The worst E. Coli outbreak in over a decade has affected a widespread swathe of the country—reaching as far as Alaska—but seems to have originated from just one location: Yuma County in southwest Arizona. According to public health officials with the FDA, the outbreak has sickened 197 people in 35 states, with five tragically having […]
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 to be one of those […]
4 “Check Engine” Warnings for Your HVACR System
As a company, we’ve observed and analyzed roughly 40,000 refrigeration systems over the past 20 years. In that time, we’ve seen the same pain points, and have heard the same complaints over and over. And each comes from one starting point: a lack of awareness by our customers about their equipment’s operation. This could mean […]
3 Solenoid Valve Issues That Can Derail Your HVACR’s Energy Efficiency
When it comes to the relationship between good performance, energy usage, and commercial/industrial refrigeration, there are many components we need to be cognizant of to ensure harmonious operation. In many cases, we know if and when the refrigeration system is running but do we know how well it’s running? Like with our post about compressor short cycling, today’s topic focuses on an […]
