The heat insulation panel with 3 layer structure improves heat insulation effect, Protects water condensation
on the outside of the tank and minimizes temperature variation of the stored water.
GRP panels protect water condensation in the tank and minimizes temperature variation of
the stored water to prevent dewdrops phenomenon.
Heat insulation cover with cloth attached inside can keep the heat of wager and never off from the cover,
so it can maintain its original shape for a long term.
