1) What are THERMODRAIN Multiple Covers with Frame used for?
-
2) Why do some installations need multiple covers instead of one large cover?
-
Multiple covers are preferred when:
- Single large covers would be too heavy or unsafe to lift
- Maintenance teams need section-by-section access
- There is a need to access different chamber components independently
- Space constraints make large single lids impractical
- This makes the system safer, easier to maintain, and more cost-effective.
-
3) What materials are used for THERMODRAIN Multiple Covers?They are made from FRP/GRP composite materials (Fiber-Reinforced Plastic / Glass-Reinforced Plastic), engineered for high strength, corrosion resistance, and long-term durability.
-
4) What load-bearing capacities are available?THERMODRAIN Multiple Covers are available in EN124-compliant load classes from A15 to F900, depending on the application—ranging from pedestrian zones to heavy industrial or vehicular traffic.
