Press Release: Introducing Dynatemp R421A™

Another Dynatemp Product You Can Count On 

Clayton, North Carolina – March 27, 2020 – We know there are many places where you can buy refrigerant. What sets Dynatemp apart from the rest is our keen focus on our customers. For many years, we have been proud to give you superior service, top-notch products, competitive prices, and speedy time-to-market. We look forward to continuing to give you our very best for many years to come.

As you know, for a number of years we have distributed the Choice® R421A product with a lubricant additive. Recently, we began a transition to producing and distributing our own Dynatemp R421A™ product. It contains a different lubricant that we believe you will find works even better. One of the reasons we are excited to bring you our new Dynatemp R421A™ product is that we now have more visibility and control over our supply chain. Not only will this reduce our costs and improve product time-to-market, but it will enhance the product quality and performance Dynatemp is known for. Bringing you our new Dynatemp R421A™ product hasn’t been easy, but, in this global and volatile economy, if we can assure our customers increased on-time delivery, lower cost, and AHRI-700 designated purity, then it’s definitely worth the effort.

We’re especially proud that our new Dynatemp R421A™ product is made in the USA. That’s important to us because it helps to reduce shipping timelines and some costs, but – most importantly – it benefits our economy and provides our fellow Americans with good-paying jobs. While we know that not every refrigerant component or part can be made in the USA, whenever we can make products locally, we will.

As we make our transition to producing and distributing our new Dynatemp R421A™ product and phasing Choice® R421A out of our product line-up, we are continuing to sell our remaining inventory of Choice® 421A. It comes as a surprise to us that Choice Refrigerants has circulated to the U.S. refrigerants market a statement that Dynatemp is selling “a counterfeit version of Choice® R421A.” This is not true. Each and every cylinder of R421A that Dynatemp sells under the Choice® brand is received directly from Choice Refrigerants.

We are also surprised to learn that Choice Refrigerants has gone so far as to call our new Dynatemp R421A™ product a “counterfeit,” a “knock-off,” and even “illegal.” This also is untrue. Our new proprietary Dynatemp R421A™ product contains a different premium lubricant than Choice® R421A, and it is sold exclusively under our own Dynatemp brand. Also, our product is produced within AHRI-700 standards and, thus, complies fully with the EPA SNAP regulations. Further, the claim that the Dynatemp R421A™ product infringes a valid U.S. patent is simply unfounded.

Had Choice Refrigerants contacted us before broadcasting these hurtful statements to the entire U.S. refrigerant market, we would have been happy to provide it with the true facts to set the record straight. Unfortunately, though, it didn’t. As you know, that’s not the way Dynatemp does business, which is why our customers trust us and our products. We’re grateful for our good relationships with you, and we look forward to continuing to serve your needs. Our new Dynatemp R421A™ product is proof that we are committed to bringing you the best.

As always, we are here to address any questions or concerns you may have. Please reach out to us at

Hydrocarbons Are The Future & The Future Is Now

Take advantage of the growing amount of equipment utilizing R290 and R600a hydrocarbon refrigerants. With state and federal HFC phase-down regulations on the horizon, now is a great time to position yourself as your customer’s go-to supplier of hydrocarbon refrigerants. Hydrocarbons, like R290 and R600a, are non-toxic, have a low GWP (global warming potential), are highly efficient, and are a cost-effective HFC replacement option. At Dynatemp Refrigerants we can offer these high-quality products at an economical price.

Following Europe’s lead, where the hydrocarbons have been in use for over 20 years, the United States is working towards full adoption of low-GWP refrigerants through state regulations with the possibility of federal legislation through the AIM Act. To meet these rapidly changing US regulations, the HVAC industry is building equipment specifically made for hydrocarbons. A couple of examples of this are here and here. Also, the IEC has increased the charge limit on equipment from 150g to 500g in self-contained commercial display cases.


R-290 is a highly refined propane. It is safe and environmentally friendly. Unlike HFCs that have a  high GWP, hydrocarbons, like R290, have almost negligible GWP. R290 replaces R134a in refrigerator applications and replaces R404a in freezer applications. It also has better heat transfer properties making your equipment more efficient.


R600a is refrigerant grade isobutane. Like R290, it is non-toxic, non-ozone depleting and has very low GWP.  R600a also has excellent thermodynamic properties. R600a replaces R12 and R134a and is much better for the environment.


While both R290 and R600a are classified as ASHRAE A3-Highly Flammable, when used correctly the risk is very low. Flammability happens when you charge fluorocarbon systems with hydrocarbons, which is illegal in the United States. There have also been fears of an increased explosion risk with propane refrigerators but studies show that there is less than a .001% chance of this occurring, even in kitchens that cook with gas. The real risk with hydrocarbons is if there is a leak in an unventilated space, like a control room. However, most of the equipment being built today is a closed-loop system to ensure safety.

The most important safety issue is that R290 and R600a can not be used in retrofitted systems, they must be used in new equipment.

An Update On The AIM Act

Did you miss the United States House of Representatives hearing titled the “American Innovation and Jobs: Legislation to Phase Down Hydrofluorocarbons”? If you did, you can check out the recorded version here.

As a reminder, this is the House version of the Senate’s AIM Act (S. 2754), which was introduced in October and is currently in committee. The AIM Act establishes a 15 year HFC phasedown schedule, while also giving the EPA the authority it needs to enforce the phasedown. Both bills have bipartisan congressional support as well as HVACR industry and environmental group support. In addition, Dynatemp Refrigerants was among thirty-two HVACR industry CEO’s to sign a letter of support for a federally mandated HFC phasedown. In the absence one, we will continue to see a patchwork of state by state phasedown legislation as we have seen with California, Vermont, Washington, and now New Jersey.

What are the next steps? Both the Senate bill and the House bill are in committee, you can track their progress through Senate Bill S.2754 and House Bill H.R.5544

If you haven’t already, use HARDI’s tool to email your Representatives and ask them to support a federally mandated HFC phasedown to give the HVACR industry the clarity it needs to plan for the next generation of refrigerants.

Frequently Asked Questions About The DynaCycle Reclamation Program

Every month we compile and share a list of recently asked questions regarding our DynaCycle Reclamation program. It’s important to become a member of a trustworthy reclamation program, like DynaCycle, where you get paid for your recovered refrigerants. At DynaCycle we accept all refrigerants, there are no freight costs, and we pay for R22 and pure HFCs and HFOs.  If you aren’t currently a member of a reclamation program and you have any questions about DynaCycle that we haven’t covered here, please reach out to us at: 

What reports and customer tracking does DynaCycle provide Distributors? 

Within about ten business days of DynaCycle receiving a shipment of filled recovery cylinders, the Distributor will receive a payment report (in pdf and/or excel format) that details the following information for each cylinder-
• Technician company information and ID#
• Distributor location and receiving-employee information
• Cylinder serial number or tag number
• Refrigerant type & purity level
• Weight of contents
• Applicable payments, charges, and credits based on Refrigerant Buyback and Service Fee Schedule

Additionally, DynaCycle will send the Distributor an EPA Compliant receiving report (pdf format) for each Technician Customer. DynaCycle reports can be customized according to the needs of the Distributor. For example, if a Distributor is sharing a portion of the program proceeds with customers, DynaCycle can produce a report detailing payment splits as defined by the Distributor.

Is freight really free both ways?

Yes! We cover 100% of the cost of freight to ship cylinders and/or tanks to and from your location.

What refrigerants does DynaCycle pay for?

We accept ALL refrigerants in the DynaCycle reclamation program. We pay for R22 and pure HFCs and HFOs.
