Aerial ASE 300 Desiccant Dehumidifier
Tough industrial absorption dehumidifier
The Aerial ASE 300 desiccant dehumidifier is a robust, versatile and professional drying unit. It is designed to perform in cold and challenging spaces, such as construction sites and renovations, in order to dry spaces effectively. It has an operating temperature range of -10℃ to +35℃. It works efficiently in warm as well as icy conditions where traditional refrigerant dehumidifiers often struggle, making it ideal for use in cellars, loft, outbuildings and vacant industrial areas. It can run all year round, including during the winter.
The Aerial ASE 300 features a high-performance EcoDRY rotor. This is a desiccant mesh that absorbs moisture from the air as it is drawn in through the air intake. This desiccant dehumidifier has an inbuilt hygrostat designed to maintain a humidity level that has been determined for a space.
The Aerial ASE 300 is a 230v machine that can be plugged into and powered by a standard household 220/240-volt outlet. It comes equipped with a 4.5 metre connection cable and mains plug. It is an efficient, versatile machine. It has no internal water tank - instead, moisture is expelled as water vapour. The machine can be used with optional flexible ducting to adapt it to a specific application and remove the water vapour from the space.
The air inlet has a 125mm flange, and the wet air exhaust has an 80mm flange. Both flanges can be fixed with ducting, to vent humid air in from a separate area and to vent water vapour out of a space. The ASE 300 also has a bracket fitted on the back, over the dry air outlet, with a single and dual ducting outlet option. Unscrew the bracket and place either end of it over the dry air outlet, to have either 1 x 100mm ducting outlet or 2 x 50mm ducting outlets on the rear dry air outlet.
We have 15m x 50mm Superflextract ducting, 12m x 80mm Thermaflex ducting, and 12m x 100mm Thermaflex available, and you can add them to your order using the tickboxes above. If you need two lengths of 50mm ducting, but 15m is too long, you can buy one length and cut it down to size.

18.75L Per 24HR Removal Rate: Fantastic moisture removal rate. Perfect for water damage remediation, building/restoration work, managing humidity in unheated spaces such as cellars, treatment plants, waterworks and more.
Operating Temperature: Range of -10℃ to +35℃: Effective even in the most challenging conditions.
Compact Size: Can be easily transported and used in small spaces such as lofts, cellars and more.
Inbuilt Hygrostat: Precise humidity control. Saves on running costs and adds extra convenience.
Duct Air In & Out: An efficient drying system with a process air intake, dry air outlet and regenerated air outlet. Duct air in from another space and duct the dry and wet air elsewhere. Wet air exhaust also has an 80mm flange for venting water vapour outside of a space.
EcoDRY rotor: High quality desiccant wheel which allows the dehumidifier to collect as much excess moisture as possible, offering high performance.
Single & Dual Dry Air Outlet: Bracket fitted on the back, over the dry air outlet, with a single and dual ducting outlet option. You can unscrew the bracket and place either end of it over the dry air outlet, to have either 1 x 100mm ducting outlet or 2 x 50mm ducting outlets on the rear dry air outlet. Optional ducting can be fixed to these outlets to vent moisture away.
PTC Heating Element: The self-regulating Positive Temperature Coefficient heating elements help to dry the rotor for continued efficient performance, especially in colder temperatures.
Usage Meters: Keep track of the operating hours/running costs by monitoring the hour and kWh counter.
Robust and Stackable: Stainless steel housing is designed to be stacked and great for storage and transport.
Standard 220v Voltage: Plugs into a standard 220/240-volt outlet and comes with a 4.5 metre connection cable with a mains plug and a cable winder for practical and safe storage.
