There are many considerations as well as concerns as you navigate through chiller sizing, selection, install then startup of your new chiller system. One concern that arises every now and then is the origin or country of manufacture of your potential new chiller. For over 25 years G&D Chillers has used non-proprietary parts. We use the highest quality components in every chiller that we build. Our multiprocessor controller to every motor throughout our package chillers can be sourced locally at your refrigeration supply house. If you are rural, we can ship directly from those parts stores or from our factory in Eugene, Oregon.

We stand firm behind a no proprietary build because we have been there, out in the field, waiting on a component with a desperate production manager, dead in the water with a broken chiller. Ours? Never! Okay, sometimes. The reality is we are very transparent on the issue. Take care of your chiller and it will take care of you but, it is a piece of equipment and over time you will have an issue. It is the proverbial, “not if but, when”. Now, when this happens, who are you calling? We recommend to our customers to call us first. We can usually get the chiller running over the phone. If needed, we can then determine to get your local technician out. Does the chiller manufacturer offer 24/7 tech support over the phone? If not, look elsewhere because you are going to have to make a call to somebody and it should be them. They built the thing, right? Whether at start up or any other situation, you must not underestimate the ability to communicate and get some help.

Your new chiller is going to be the most critical functioning piece of equipment at your production facility. Everything depends on it properly working. At G&D, we take seriously the relationships we develop with our customers. We are not satisfied with anything less than perfection. Our partnerships sustain our reputation. You will forfeit that level of accountability if you source an overseas chiller. Most would consider everything I’ve said here as some common sense considerations. However, from time to time, people make the mistake of letting their production rest on the shoulders of a poorly built foreign chiller. To them, here is our number: 800.555.0973. It is likely you are fed up and ready for a new, made in the USA, G&D Chiller. Give us a call, we are happy to have the opportunity! To the rest of you, keep your faith in the red, white and blue!

Paul Johnson, G&D’s Director of Technology and R&D

In the ever-evolving refrigeration industry, advancements in technology and materials are crucial for achieving peak performance and meeting today’s challenge of mitigating climate change. One standout innovation is the use of propane (R290) as a refrigerant, a topic we recently explored with Matteo Iobbi, CTO of Frascold, a leading global manufacturer of the most technologically advanced, semi-hermetic compressors on the market today. Frascold partnered with us at G&D Chillers for our new Elite 290 propane chiller line.

Propane’s success in Europe stems from early adoption in niche markets, proving its energy efficiency, versatility, and effectiveness. Over time, stringent regulations on high Global Warming Potential (GWP) refrigerants accelerated propane’s integration. Today, propane is a staple in mass-produced products such as heat pumps and cooling units across Europe.

As we officially launch this line using alternative refrigerants in the U.S., Matteo shared his insights on propane’s ascent in Europe over the past decade and what American end users can anticipate. Read on for our informative Q&A with Matteo.

What is your role at Frascold? 

My daily role involves relationships with customers, distributors, and other stakeholders in the refrigeration HVAC industry. This requires a tight exchange of information with our departments in our headquarters in Italy in order to better serve the U.S. market and tailoring our products.

I am also involved in industry events and initiatives where I can share insights on the latest Frascold technologies and pilot programs around the world.

How has propane taken off in Europe? And why do you think it’s been successful? 

The widespread use of this refrigerant is related to its implementation in mass production products such as heat-pumps and cooling units. The success of the R290 refrigerant comes from decades of niche market implementation, demonstrating its energy efficiency, versatility and effectiveness. Regulations on the use of high-GWP refrigerants has, of course, been an accelerator.

As propane begins to take off in the U.S., what recommendations do you have for the end-user? What should they be aware of based on what you’ve seen in Europe?

Ensure that end-users are aware of proper installation, maintenance procedures, and safety guidelines in order to mitigate any risks. Maintenance engineers have to be trained to handle flammable refrigerant and safety devices.

We’ve seen huge benefits of the Elite 290 line, both in efficiency and near-zero global warming potential. What are the major factors that have contributed to the growth and demand in the European market?

The fact that R290 operates within the pressure ranges that manufacturers are used to dealing with, together with efficiency levels and increased public awareness on direct and indirect emissions, have strongly contributed to the growth.

Again, the regulations made the next step in pushing this technology forward easier.

In summary, what are some of the biggest drivers for customers moving toward propane refrigeration like our Elite 290 line?

Outstanding seasonal efficiency, therefore indirect emissions reduced, and negligible direct emissions due to use of R290, are the main drivers. A thorough study has been done of the Elite 290, in order to minimize the charge. Being a chiller with a very low refrigerant charge, for outside installation, with state-of-the-art protection devices make the unit operationally extremely safe. Safety and seasonal efficiency are, in my opinion, the drivers.

Were there any concerns or barriers for customers choosing propane? If so, what solutions have you seen work and have helped drive growth in the market?

The main barrier, like in any other disrupting situations, is “we have always done it this way.” The development of dedicated safety standards and the use of advanced technology has helped to overcome these barriers. Training and education regarding safety, handling, and installation guidelines together with clear maintenance procedures have alleviated the concerns and grown the self-assurance on this type of product.

Do you have any knowledge of where the U.S. regulatory authorities are in writing new codes or standards in allowing R290 to be more mainstream?

We at Frascold are closely following the evolution of the U.S. standards such as ASHRAE 15 and UL 60335-2-40, as well as the EPA’s Significant New Alternatives Policy (SNAP) program. They are all moving towards the development of clear safety requirements as well as increasing the limits of the refrigerant charges.

Leading the Charge

G&D Chillers stands at the forefront of this refrigeration revolution, setting new benchmarks in efficiency and safety. As the U.S. market embraces propane, insights from industry leaders like Matteo Iobbi at Frascold underscore the importance of rigorous training, robust safety protocols, and compliance with evolving regulations. Together, we can forge a greener, more efficient future for refrigeration.

Most people enjoy a snow filled winter, but all that weather can have some adverse effects on your glycol chiller. There are areas of the nation that experience extreme weather conditions. Heavy snowfall, freezing rain, ice storms and extreme low ambient conditions. Here are a few topics to keep in mind as the winter chill approaches.

Your glycol chiller is built to handle the worst conditions that mother nature can bring. That being said, snowfall is a hard one to combat. Excessive snow builds up around the chiller can prevent the proper air flow through the condenser causing nuisance shutdowns or alarms. Shoveling snow is not something most people look forward to, but it is an essential part of keeping your chiller operable. Keep in mind the minimum clearances of the chiller. Three feet of clearance on the intake side and open to free air (no obstructions) on the exhaust side. Heavy snow may bring treachery in other forms as well. With a snowpack on your roof and an unsuspecting chiller sitting below, ouch! All that snow can slide off a building and crush your glycol chiller. Ice can have the same effect. Heavy icicles breaking from an overhang can cause severe damage.

Usually with precipitation comes low ambient temperatures. If you have your glycol chiller located in an area that sees temperatures dip down to the low single digits, we should talk about your glycol mixture. G&D chillers operate at 35% glycol to water ratio (26.5 brix) but increasing that mixture to 40% (29.3 brix) in extreme low ambient conditions may be recommended. That effectively lowers the freeze protection of the glycol to an acceptable level. Even in temperatures below 0°F, a 40% mix coupled with keeping a pump running will prevent the piping from freezing. Keeping that flow moving through the process is key. It’s the same concept as rivers and lakes. Flowing river water will rarely freeze, but stagnant water in lakes or ponds will.

It is highly recommended to leave power to your glycol chiller during winter. However, these winter storms can bring unexpected outages. A power outage with extreme low ambient temperatures can be disastrous to your glycol chiller. If the outage lasts only a couple hours, you won’t really have anything to worry about. In the event of an extended outage, some steps need to be taken to protect the chiller. The best option would be a generator. This generator does not need to be sized large enough to power the entire chiller, just big enough to keep your pump running to provide flow and ultimate freeze protection. At an absolute minimum, a generator to run a space heater. Placing the heater in front of the chiller and covering it in tarps will keep it from freezing solid. The worst-case scenario would be to drain the glycol reservoir and all your plumbing to avoid freezing. Think about a glass bottle full of water in the freezer. It will expand and break.

Winter storms could also prevent you from even being able to reach your facility. The roads may be impassable. Keep an eye on the weather report and take precautionary measures as needed. If you don’t expect to be able to make it to the facility, leave the chiller running. Keep tank valves open, even if they are empty, to keep glycol moving. This can also help put an ambient load on the chiller to keep glycol temperatures up. These tips will also apply if you are planning a production shut down during the winter.  If you have any questions about chillin’ in the winter, just give us a shout!

Get Your Cooling System Ready for the Season Ahead

As spring arrives and vineyard life begins to bloom again, it’s the perfect time to wake your chiller from winter hibernation. A smooth startup now means reliable cooling when you need it most — whether you’re cold-soaking rosé lots or prepping for bottling.

Below is a helpful step-by-step guide to safely and efficiently hook up and prepare your chiller for winery use this season:

Spring Chiller Startup Checklist

1. Clean the Condenser Coils

• Spring debris like cottonwood, pollen, and leaves can restrict airflow.
• Use a soft brush or coil-safe cleaner to remove buildup. For heavy grime, a gentle rinse with water may help — just avoid damaging the fins.
• Straighten bent fins with a fin comb if needed.

2. Remove Winter Protection

• Take off tarps, overhangs, or insulation used for winter protection.
• Ensure there’s no trapped moisture, which can lead to rust or mold.

3. Inspect Power & Electrical Connections

• Confirm that electrical wiring is intact and connections are tight.
• Check breaker panels, disconnects, and look for any signs of wear or corrosion.
• Only turn on power after all visual inspections are complete.

4. Check Fluid Levels & Glycol Concentration

• Test glycol levels for proper freeze protection.
• Top off fluid if needed and inspect for leaks or degradation in the reservoir or lines.
• Clean out any sediment or gunk in the tank before cycling fluid.

5. Reconnect Hoses & Inspect Fittings

• Reattach any process or return lines.
• Check for dry rot, cracks, or loose hose clamps. Replace or tighten as needed.
• Confirm all fittings are sealed and properly aligned.

6. Run the Chiller in Manual/Test Mode (if applicable)

• Power on in manual mode to monitor startup behavior.
• Listen for any unusual sounds, check for error codes, and monitor pressure levels.
• Run for 10–15 minutes to ensure system stability.

7. Verify Pump Operation & Flow Direction

• Confirm coolant is flowing freely through your tanks, heat exchangers, or jackets.
• Bleed air from the lines if your system is prone to airlocks.
• Look for smooth, consistent flow — surging could indicate a clog or air pocket.

8. Review Set Points & Controls

• Recalibrate temperature settings to match your current winemaking needs.
• Double-check programmable schedules, alarms, and remote monitoring setups if used.

9. Perform a Final Walk-Around Inspection

• Look for signs of leaks, oil spots, or corrosion.
• Ensure all safety covers and panels are secure.
• Verify emergency shutoff switches are labeled and accessible.

R290 vs C02

• R290 is tomorrow proof because it has an extremely low global warming potential
• Zero ozone depletion potential
• Contains zero PFAS chemicals
• 70% more efficient than CO2
• A2Ls are a great interim solution, but they won’t be around forever.

CO2 has major problems that make it a poor choice for the future, it is highly inefficient, equipment, maintenance, and operational costs are high, and reliability is poor.

A quick note about A2Ls which are a good interim solution, but they won’t be around forever.

• Europe is already starting to phase them out because of the PFAS (forever) chemicals they contain.
• New York has already set a timeline to eliminate all the existing A2L refrigerants (even in existing systems) that exist today because of their global warming potential. California and the rest of the nation won’t be far behind.
• A2Ls all have multiple components, and glide (various component gasses boil at differing pressures and temperatures) – this adds to the cost of repairs when leaks occur, as most of the time, the entire refrigerant charge must be replaced since different parts of the refrigerant leak at different rates.
• A2Ls are close to R290 in efficiency, and far more efficient than CO2
