Desiccant bed support grid Component – Chemical Manufacturing

Q: What is the primary function of a desiccant bed support grid?

To provide structural support for desiccant material while ensuring uniform airflow distribution and preventing desiccant particle carryover into downstream equipment.

Q: How does mesh size affect performance?

Mesh size determines the balance between structural support and airflow resistance. Smaller mesh provides better desiccant retention but increases pressure drop, while larger mesh reduces pressure drop but may allow finer particles to pass through.
