KELSO FRP Dome Covers​

Syntechnics Environmental Cover Systems

Syntechnics Environmental Cover Systems efficiently capture odors and vapors created by substances contained in tanks or reservoirs.  This is a great capital investment for co-generation facilities pulling methane off of anaerobic digesters.

Domes cover circular tanks from 25 to 132 feet in diameter. Arches cover rectangular tanks as large as 90 feet in clear span. Flat covers cover rectangular tanks as large as 45′ in clear span and can be adapted for use on circular tanks as well.

Made of Fiberglass Reinforced Plastic, they provide maximum strength at minimum weight, are aesthetically pleasing, meet demanding environmental requirements and are resistant to corrosion. These FRP covers also minimize moisture collection points by eliminating excess flanges, fasteners and weldments. They permit use of complex shapes at low costs, minimize maintenance and operating costs and can be assembled on-site.

SynTechnics Environmental Cover Systems provide cost-efficient covering of virtually any size or shape for almost any tank and reservoir.

Corrugated Flat Cover Mounting


Modern female contact molding processes are used to manufacture our environmental cover systems. Cover panels are monolithic molded sections consisting of multiple layers of fiberglass and resin. Each panel is designed to meet or exceed loading requirements. Interior surfaces are coated with a resin-rich finish to provide the proper corrosion resistance. Exterior panel surfaces are protected from outside conditions by a specially formulated gelcoat, which is molded into the primary laminate. The strict manufacturing controls and tested designs make the SynTechnics FRP covering system a leader in the industry.

Covers referenced in water and wastewater treatment projects usually refer to Launder Covers which function as odor control hoods that entrap noxious gases generated in the wastewater treatment process. Launder Covers also prevent the growth of algae by elimination of sunlight; this reduces weir maintenance and enhances flow consistency. Covers are also used to cover other openings where access is needed but for safety and other reasons the opening needs to be covered when not being utilized. Covers are custom designed and can be used in both round and rectangular clarifiers, sludge thickeners, channels and other openings.
