The Trade-off

Neither is universally better; they solve different problems.

Choose Plate When

• You want no moving parts and minimal maintenance
• Air streams must stay fully separated (hospitals, labs)
• Moisture recovery is not required

Choose Rotary When

• You need the highest effectiveness (up to 85 percent)
• You must recover humidity in a humid climate
• The unit is large enough to justify the motor and seals

Simple Rule

If isolation and simplicity matter most, pick plate. If peak performance and moisture recovery matter most, pick rotary. See our full comparison for the detailed table.
