Studying the performance of refrigerants is of our passions at SRC and we've invested heavily in learning as much as we can about them. Last week, ATMOsphere held their annual natural refrigerants conference in Washington D.C. The conference took place on June 7th and 8th and Super Radiator Coils sent three engineers to learn about the natural refrigerant market, emerging applications, new technologies, and more. Read below to hear what SRC's Ken Allen, Will Klick, and Gail Miller took away from the conference and their thoughts on the future of natural refrigerants. 

Our Refrigerant Focus series delves into the history, properties, suitable applications, and pros and cons of some of today’s popular or otherwise noteworthy refrigerants. This installment will focus on R-744 (CO2).

Nate Budryk: Hello and welcome to another SRC podcast. Today, we’re talking about one of the poster children of the natural refrigerant push, which is CO2, also known as R744 or carbon dioxide. Today’s conversation will include a brief overview of CO2, some specifics of the refrigerant & CO2 systems, and some industry general best practices. To help us do that today are two CO2 experts: Will Klick, who serves as sales application engineer for SRC, and Wynand Groenewald, a director at Future Green Now, which is a CO2 consultancy based in South Africa. Will and Wynand, how are you doing, guys?

Are you getting the most out of your steam system investment? Steam has been used as a heat transfer medium for centuries. Today, it remains a popular option for commercial heating and a multitude of industrial applications. But, in our experience, the industry’s understanding of steam and steam equipment is inconsistent, and we’re hoping to help make things a little clearer as it relates to the following areas.

Super Radiator has served the food manufacturing sector for decades. It’s one of our bedrock industries and over the years, we’ve come to learn quite a bit about food production facilities, their environments, and coil designs that work well there.

Hello and welcome to another SRC podcast. On today's episode, we'll be talking about a new EPA rule regarding the phasedown of hydrofluorocarbons. We touched on this in our last recording, and since, there has been developments in terms of at that time, it was a proposed rule. It has now progressed to the point where it is a final rule. Since that development, we thought it'd be a good time to revisit this topic. Today, we're going to be talking about exactly what the implementation of that rule will look like, and then we'll also quickly review the contents of the rule.

Hello and welcome to another SRC podcast. For this recording, we're going to be focusing on a proposed new rule from the EPA that's titled "Phasedown of Hydrofluorocarbons: Establishing the Allowance, Allocation, and Trading Program under the American Innovation and Manufacturing Act."

As a custom coil manufacturer, we often speak with facilities managers and maintenance professionals about coil replacements, upgrades, and retrofits. These jobs often require us to design a coil for an existing space, which can be tricky if you're not sure what to look for. For this post we’ll explain that process, including:

• Common size-in-place scenarios for commercial HVAC coils
• Some best practices when replacing a coil
• Other important coil replacement considerations

Our Application Spotlight series focuses on interesting and noteworthy functions for which our heat exchangers are used. For this post, we’ll take a look at how heat is recovered during the incineration of dewatered waste solids that are separated from waste water during the treatment process. We’ll look at:

1. Background on the incineration process
2. Uses for recovered heat and overall benefits
3. Coil design in incineration plant waste heat recovery (WHR) systems
