Accessories & Services
At Prime Tank Systems, we offer a wide range of accessories and engineering services that complement our main product lines. From critical sealing components and custom fittings to installation support and retrofit solutions, our accessory offerings are designed to optimize tank safety, performance, and longevity.
Emission Control Devices
Advanced solutions designed to minimise VOC emissions from storage tanks, ensuring compliance with global environmental regulations. These systems enhance sustainability by capturing or reducing vapour losses during filling, breathing, or operational cycles.
Rim Vents
Designed to maintain internal pressure balance and prevent vapour buildup, rim vents play a critical role in floating roof tanks equipped with sealing systems. Prime Tank Systems’ rim vent solutions ensure safe ventilation, reduce the risk of vacuum or overpressure conditions, and support environmental emission control.
Geodesic Dome Roofs
Geodesic dome roofs are lightweight, self-supporting aluminum structures engineered to cover atmospheric storage tanks. Their modular design ensures exceptional strength-to-weight ratio, eliminates water accumulation, and minimizes emissions by providing a secure, weather-resistant seal. Ideal for petroleum, chemical, and water storage applications, they offer long-term durability with minimal maintenance.
Internal Floating Roofs (IFRs)
Internal floating roofs are engineered decks that float directly on the product surface inside storage tanks, minimizing vapor emissions and product losses. Designed for compliance with API standards, they enhance safety, reduce environmental impact, and are ideal for petroleum and chemical storage applications.
Roof Drain Systems
Engineered to safely remove rainwater from floating roofs, these systems prevent roof overloading, product contamination, and structural damage. Designed for flexibility and durability, they ensure continuous drainage under varying tank conditions.
Diffusers & Spray Nozzles
Prime Tank Systems offers precision-engineered diffusers and spray nozzles for above ground storage tanks, designed to ensure uniform fluid distribution, effective tank mixing, and sediment prevention.
Floating Roof Rim Seals
Prime Tank Systems rim seal solutions ensure tight vapor control between the floating roof and tank shell, reducing product loss and emissions. Available in primary and secondary configurations, our seals are compatible with a wide range of stored products and designed for durability, flexibility, and compliance with international environmental standards.
Floating Suctions & Skimmers
Floating suction assemblies and skimmers are designed to draw liquid from the uppermost and cleanest level of a storage tank, ensuring product quality and minimising contamination from water bottoms or sediments.
