Trionic Corp is a leading water holding tank distributor serving Chicago and the surrounding region, providing a wide selection of storage solutions for potable water and wastewater applications. The company supplies durable, high-quality tanks designed to meet the needs of marine, recreational, commercial, and industrial customers. Built for strength, longevity, and regulatory compliance, their tanks are engineered to perform reliably in demanding environments.
One of the primary product categories Trionic Corp provides is fresh water holding tanks. These tanks are specifically designed for the safe storage of potable water in applications such as RVs, boats, food trucks, mobile medical units, and remote facilities. Manufactured using seamless, rotationally molded polyethylene, the tanks are resistant to corrosion and cracking. Many models are made with FDA-compliant materials to ensure water safety, and they are available with pre-installed threaded openings or blank configurations to allow for custom fitting placement.
In addition to fresh water storage, Trionic Corp distributes greywater and blackwater holding tanks. Greywater tanks are used to collect wastewater from sinks, showers, and other non-toilet plumbing fixtures, while blackwater tanks are designed to safely store sewage from toilets. These wastewater tanks are commonly used in marine vessels, RVs, and locations without direct access to municipal sewer systems. Designed with thick walls and secure fittings, they provide dependable containment and allow for proper venting and pump-out connections.
Trionic Corp offers water holding tanks in a broad range of sizes to accommodate different capacity requirements. Smaller tanks are ideal for compact spaces or lightweight installations, while larger-capacity tanks are suited for high-demand applications that require significant water storage. This variety enables customers to select the appropriate tank based on available space, system design, and intended usage.
For customers seeking enhanced performance, Trionic Corp also provides premium holding tank systems with advanced features. These may include reinforced fittings, odor-control designs, inspection ports, and vacuum relief valves. Such enhancements are particularly valuable in marine and sanitation-intensive environments where durability and leak prevention are critical.
