Boat Dehumidifiers & Moisture Absorbers

A dehumidifier is an essential tool for boat owners during the damp winter months. By removing moisture from the air, dehumidifiers help to prevent damp and mold. This helps to protect your boat’s interior and prolong its lifespan.

Types of Dehumidifiers for Boats

When choosing a dehumidifier, it’s important to consider the space, conditions, and your power requirements. There are three main types to consider:

1. Passive Dehumidifiers (Non-Electric)

  • How They Work: Use moisture-absorbing crystals to draw water from the air.
  • Best For: Small spaces like cupboards, lockers, or compact boat cabins.
  • Advantages:
    • Simple and easy to use.
    • They can be left unattended.
    • Affordable and silent operation.
  • Considerations: Limited capacity; requires regular replacement or refilling of crystals.

2. Compressor Dehumidifiers (Electric)

  • How They Work: Use a cooling coil to condense moisture from the air.
  • Best For: Warmer temperatures and general-purpose moisture removal.
  • Advantages:
    • Highly effective in moderate climates.
    • Energy-efficient operation.
  • Considerations: Performance may drop in colder temperatures typically found on boats in winter.

3. Desiccant Dehumidifiers (Electric)

  • How They Work: Desiccant dehumidifiers work by using a desiccant wheel to absorb moisture. They then release warm dry air back into the space.
  • Best For: Cooler environments, such as winter conditions on board.
  • Advantages:
    • Operates effectively at low temperatures.
    • Slightly warms the air, helping to reduce condensation.
  • Considerations: Slightly higher power consumption than compressor models.

Why Choose an Electric Boat Dehumidifier?

Electric dehumidifiers come equipped with features to suit marine environments:

  • Water Collection Options:
    • Built-in water tanks for convenience.
    • Optional continuous drainage using a hose attachment (ideal for unattended use).
  • Unattended Operation: Many models can run continuously, ensuring your boat stays protected even when you’re away.

Dehumidifiers are a simple yet effective way to combat moist air, damp and condensation. All in aid of protecting your boat’s interior and preventing costly maintenance.

Whether you opt for a passive model for smaller spaces or an electric dehumidifier for larger cabins, Force 4 Chandlery offers a range of options to suit your needs. Browse our collection today and enjoy a dry, mold-free boat all winter long.
