Reason number two is our dry cooler heat rejection, or at least our water-based heat rejection on every piece of equipment. The Quest IQ line uses a water-based or glycol-based heat rejection so that we can eliminate the issues associated with split DX in a controlled environment agriculture market.
And split DX in this market is a challenge because when you’re running refrigerant lines to a condenser outside, you’re now trying to manage refrigerant and oil migration and low ambient conditions – and that is a really big and definite challenge in this marketplace. You’re also relying on your mechanical contractor to install those components properly – and that is becoming more and more challenging to do.
With a glycol or a dry cooled system, we’re able to reduce the refrigerant charge on our split systems by up to 90%, and in Compressor Wall, even more than that, which helps to eliminate refrigerant liabilities in your space. It reduces your service cost on an ongoing basis and prevents some of the new issues around things like ASHRAE Standard 15, which is the amount of refrigerant allowable in a mechanical space.
And these are also much less expensive to maintain. If you ever develop a leak in a glycol circuit, you end up with some pink goo on the roof. And we use food grade propylene glycol as our glycol solution. So, that is a very inexpensive fix. And there’s no EPA reporting requirements. You’re not attracting any undue attention into your facility. But still able to achieve a very efficient and reliable system.
Again, by decoupling the compressor from the outdoor ambient condition, we can operate those compressors as efficiently as possible in any ambient condition, down to minus 40 degrees, without any trouble at all. And that’s something that other manufacturers just can’t say.
