What the Media Does

The wheel media stores and releases both heat and moisture. Its coating decides how much water vapour transfers and how the wheel ages.

Media Types

• Aluminium (sensible) - no moisture transfer, lowest cost
• Molecular-sieve coating - strong latent transfer, durable
• Desiccant paper - high moisture uptake, needs careful humidity control
• Polymer / hybrid - corrosion-resistant, good for harsh air

Selection Criteria

• Required latent effectiveness at your humidity ratio
• Air cleanliness (corrosive or particulate loads)
• Pressure drop and wheel depth trade-off

Verify

Use the Eurovent or AHRI 1060 certified latent effectiveness at your operating point, and confirm the media is rated for your airstream.
