Air-Dryr 500 Marine Electric Dehumidifier
The Air-Dryr 500 is an active, electric dehumidifier built specifically for enclosed marine spaces. Unlike passive crystal absorbers, it continuously circulates and dries the air in your cabin, berth, or storage compartment — keeping humidity in check around the clock without needing refills or replacement media.
Compact and purpose-built for boats, the Air-Dryr 500 plugs into a standard 120V AC outlet and quietly works in the background to prevent the mildew, corrosion, and musty odours that come with damp, enclosed spaces. It’s an ideal solution for boats on shore power during storage or the off-season.
Specifications

- Type: Electric thermoelectric dehumidifier
- Power: 120V AC
- Application: Enclosed marine spaces — cabins, berths, lockers
- Part Number: DIN-1459
Best For
- Boats on shore power during storage or winter layup

- Protecting electronics and wiring from corrosion in enclosed spaces
- Continuous, maintenance-free moisture control without refills
Prefer a No-Power Option?
If your boat isn’t on shore power, consider the passive Dri-Z-Air system instead:
- Dri-Z-Air Dehumidifier Unit with Crystal — complete starter kit, no power needed
- Dri-Z-Air Crystal Refill 13 oz — replacement crystals
- Dri-Z-Air Refill 60 oz — bulk refill option
- Dri-Z-Air Refill Jug 4.54 kg — best value for multiple compartments
Parts Desk Insights
Best use case: The Air-Dryr 500 is the right recommendation for customers who have shore power and want a set-it-and-forget-it solution. It’s especially popular with liveaboards and customers storing a boat over winter at a marina with power hookups. The key differentiator over passive crystal products is that it requires no maintenance or refills — just plug it in and leave it. If a customer doesn’t have shore power access, redirect them to the Dri-Z-Air Dehumidifier Unit with Crystal as the passive alternative. For customers on the fence about the price, point out the long-term savings versus buying crystal refills season after season.
