G&D Chillers Are Built in the USA
08 July, 2020

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!

What Temperature Should I Set My Chiller To?
18 May, 2020

On the face of it this seems like an easy question to answer, but the more you look into it the more opaque it can become.  There are a handful of things to think about when setting your chiller.  The first thing I would think about is the fact that all refrigeration cycles operate more efficiently as the set temperature is increased.  For this reason, you wouldn’t want to set your chiller as low as it will go because you will cause your chiller to run less efficiently.  Another reason you don’t want to set your chiller too low is based around the freezing point of whatever your product may be.  We have seen beer freeze to the inside of a fermenter because of the glycol temperature being set too low.  I have also heard of brewers breaking the float valve on the inside of their Cold Liquor Tank (CLT) because a large piece of ice came loose and sheared it off.  So for these two reasons, I will recommend customers to set their chiller as high as possible while still being able to “get the job done.”


In short, it matters what the job is.  In a brewery you will likely see ales fermenting from 64°F up to 72°F and lagers fermenting at 50°F to 56°F.  However, in a brewery maintaining fermentation temps isn’t the only thing the chiller has to do.  Often brewers will cold crash their product down to 32°F to 34°F.  For this reason we often recommend brewers set their chillers at 26°F to 28°F to facilitate the cold crash function as well as to maintain brite tanks that operate at 32° to 34°F as well.

In a distillery you will often see fermentations take place around 80°F+ and there is no need for cold crashing.  For this reason we can often set distillery chillers as high as 60°F to 70°F and take advantage of running more efficiently at higher temperatures!

Another large cooling load in a lot of breweries is the wort heat exchanger.  If you are using glycol in a two stage heat exchanger you will be adding a large load to your chiller.  The lowest that wort out of the heat exchanger will be going to is ~50°F if you are making lagers.  As we stated before though, you will likely have your brewery chiller set to 26°F or so, which is overkill for this service.  You might ask then, why not turn up the chiller when you are knocking out?  That isnt a bad idea if your facility can manage that!  If you can turn off all of your crashing tanks and brite tanks for the 45 minutes or so it takes to knock out your wort the chiller can run at a higher temperature, more efficiently, without any negative side effects.  If you can’t do that then you will have to use a lower temperature glycol to manage the cooling and deal with the lower efficiency ratings.

Wineries are similar to distilleries in that there is generally no cold crash requirement, so the minimum temperature the chiller has to maintain is usually set by fermentation temps, 50°F to 58°F for whites and 68°F to 78°F for reds.  So in a winery you can usually get away with setting your chiller at 45°F if you are fermenting whites and up to 60°F if you are fermenting reds.

Looking at all of this information, you might think, “I’m more confused now than when I started!”  That’s fine, feel free to reach out to one of us here at G&D and we can help you with the appropriate set temperature for your chiller based on our 26+ years of experience!

Chillin’ in the Winter - How to Keep Your Glycol Chiller Operating Reliably with Old Man Winter Breathing Down Your Neck
22 January, 2020

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!
