Founded in 1993, G&D Chillers initially bought chillers to the wine business. The firm rapidly moved into the craft beer and distillery industries earlier than increasing into hashish extraction with a line of low-temperature gear.

Lead gross sales engineer Scott Timms broke down among the most typical questions the crew hears.

How chilly can G&D’s chillers go?

Our low-temp line can take Dynalene HC-50, which is the fluid we use, all the way down to minus 50 levels Fahrenheit. That method, you will get your course of all the way down to minus 40 levels Fahrenheit. At minus 40, you’re going to have the ability to care for dewaxing and winterizing the product and you may lower out a complete step later within the course of.

How does the chiller run effectively at these temps?

We use a handful of issues to run effectively at these temps. We begin with the compressor itself. The compressor is a two-stage, semi-hermetic, reciprocating machine that may deal with the broad strain differential required to get down to those temperatures.

We additionally implement inside that compressor an economizer sub-cooler that helps the compressor run extra effectively at that place. We additionally use elevated quantities of insulation and particular pumps and issues like that to make the unit run extra effectively at these temperatures.

Is this a turnkey bundle?

Like all of our chillers, it is a turnkey bundle. It comes with its personal onboard pump, its personal onboard reservoir, and all of the piping you want. Essentially, it’s a black field. You hook up piping and electrical, add the fluid you want, and also you’re able to rock.

What different particular design options have you ever included to get the hashish chiller to chill at ultra-low temps?

We’ve built-in a seal-less magazine drive pump. A whole lot of instances in these low-temp conditions with the Dynalene HC-50 and in addition with the temperature itself, leaks round seals are a significant challenge. Our design eliminates that challenge utterly. We’ve additionally utterly modified out the instrumentation all through the entire state of affairs to function properly at these temperatures and management the techniques extra effectively.

What kind of upkeep ought to I anticipate for the chiller?

The low-temp chiller would require some upkeep, after all. We suggest having a superb relationship with an area technician who can come out yearly, take a look at the condenser portion of the chiller, ensure that it’s clear and working effectively’ look by the refrigeration system and ensure all of the little issues we search for in there are optimized.

Also, the tech ought to test the Dynalene resolution, as all year long it’d dilute itself somewhat bit. One of the primary points you possibly can have inside this chiller is the Dynalene resolution being off-spec. So, ensuring that’s right yearly is particularly necessary.

Do you employ proprietary components within the chiller?

All of our components are nonproprietary. We delight ourselves on it. That method, any technician who comes out can look contained in the gear and never be completely blown away. They’ll be capable to see components they’ve seen in some other chiller or HVAC state of affairs earlier than. This is specialised, for certain. But on the identical time, they’ll be capable to function and discover one thing near you to get you again up and operating if there’s a downside.

How do the extraction chiller controls work?

We use a single-point electrical connection that makes life lots simpler at startup. We have additionally carried out a microprocessor controller that’s particularly designed for the refrigeration business. One neat little add on to that is that it has a spot so that you can plug in your native community connection, which can join the unit to the web and allow you to see your controller from wherever on the planet. When buying a unit, we’ll offer you a 12 months of that service totally free.

On high of that, with that service we’ll truly be capable to log into your controller from right here in Eugene, Oregon, take a look at all of the refrigeration specs, and be capable to determine issues out earlier than your tech even will get out. And hold your downtime to a minimal.

Within all our models, we make the most of circuit breakers versus fuses, since you’re going to have all types of points that might come about with soiled energy or an influence surge. It’s at all times going to occur on a Friday night time, late. Then you’re going to be down all weekend as a result of you possibly can’t get to the electronics retailer to get a substitute fuse.

With our controller, you’ll be capable to simply flip it again on. We’ve designed the entire setup to be as user-friendly as attainable so that you make the choices and modifications that you must with none issues.

Where ought to I find the extraction chiller?

These chillers are designed to be outdoors. There’s a big condenser part, and all the warmth that’s inside your course of and the warmth that’s produced by the gear itself will exit by the condenser. So, finding the chiller indoors will trigger some actual points. With the unit outdoor, it is going to push all that warmth outdoors.

The outsized condenser is designed to handle super-hot conditions. We’ve additionally put in variable frequency drives on the followers and different management optimizations that assist the gear run at super-cold temperatures with none points.

What kind of piping is required?

It’s all about being tremendous chilly, so pipes want to have the ability to handle the temperature and the insulation resolution that’s going to forestall warmth ingress, which might trigger a chiller to be undersized.

We suggest ABS plastic, and there are merchandise that come pre-insulated. It’s very simple to put in. Copper is one other nice one materials, or stainless-steel. Definitely use a clamshell-type insulation excessive of copper or stainless-steel. Other than that, simply take into consideration stopping warmth ingress.

What providers does G&D Chillers provide?

We have 24/7 customer support technicians who can be found to deal with any issues. We can design complete hashish extraction amenities. We will help you optimize your chilling resolution by splitting up pulldown. We can optimize your facility with high-temp chillers that may handle the solvent restoration aspect of issues or convey all of it collectively into one chiller — no matter makes essentially the most sense.
