Polygon showcases their temporary environmental control services provided for the Alexan Gateway project in Kent, Washington, in collaboration with Absure Construction. The editorial overview provides a summary of the key points covered in the video.
Polygon’s role in the project is to deliver temporary environmental control solutions to three buildings at the site. They utilize a combination of desiccant dehumidification and gas-fired indirect heaters to create dry and heated air. The focus is on achieving the right air distribution with sufficient velocity and volume to create a positive pressure throughout the building.
The video takes viewers inside one of the buildings, highlighting the stacked desiccant dehumidifiers delivering 10,000 CFM of air. Flex ducts and ten mil polylay flat tubes are used for air circulation, ensuring durability and efficient drying. The strategically placed perforations in the distribution ducting allow dry air to flood the floor space, accelerating drying times for various materials such as joint compound, wood framing, and floor leveling products.
Polygon’s centrally located system and temporary ducting enable effective distribution of dry, heated air throughout the construction environment.

So here we are today at the Alexa Gateway project with Absure Construction in Kent Washington. We've got a total of three buildings out here. We are providing temporary environmental control services for. Got a combination of desiccant dehumidification here creating dry air and high volume. Got it then passing through an electric or I'm sorry. A gas fired in line indirect heater, and that low vapor pressure heated air then being distributed to the building and ducted throughout the entire space. Another quick look at the desiccant Diam notification system here. We're stacked. Students are stackable. Take up less real estate. And we got a combination about five thousand CFM each, so it's only a ten thousand CFM. And that is really the key, making sure you have enough velocity and the right air distributed throughout the building to create a positive pressure. Let's go inside and take a look. Here we are now on the top floor. A building three. And this building is still coming together. But you can see we've got our two desiccant dehumidifiers stacked here delivering ten thousand CFM of air. Those are being fed into the indirect fire heaters and then that air is then brought up to the window opening Get a nice job on the plywood poured up here, and we're running flex duct which is rigid. It's got a coil in it. Very durable. And then once we're inside the space, we switch to a ten mil polylay flat tube. And this suspends the dry, low vapor pressure air. It is so critical to accelerating dry times in this environment. You can see how clean this is. Century located system down below brought into the building, distribution ducting, and this is perforated. For each project. So we've got dry air blowing into this unit. As you walk down, you'll find more perforations and the key It's just the velocity and the volume of the air that we're delivering. Again, there's another perforation. And dry air. Just continuously flooding the floor space. Anything that's holding a higher vapor pressure, then the vapor pressure of this ambient air is going to give off moisture. That's how we're able to produce eleven to twelve hour dry times on joint compound. That's how we're able to get the moisture content down in the wood framing. And lastly, The JIP Creek, the floor leveling product, introduces a significant amount of moisture, and the desiccant dehumidification system does a great job of drying that material at an accelerated rate. So as we continue on, you can see just how much of this just distribution ducting can be ran off of the centrally located system. Often times we'll use elevator shaft openings as a means of egress into the building. They didn't want to do that. Because they've got work going on. So we chose the exterior and used a window opening with the board up. Again, just like the temporary lighting, we're running temporary ducting. And this is continuously dispersing dry, heated air, to the construction environment. These guys love it. Contractor loves it because it accelerates the schedule. Good stuff. Hand it over to Polygon. And we'll knock it out of the park.
