OPW Engineered Systems CTS — Compact Torsion Spring (CTS) Hose Loader
Overview
The CTS Hose Loader combines compact dimensions with advanced torsion spring technology to deliver efficient bottom-loading performance in confined loading rack environments. The integrated torsion spring system is housed within the swivel assembly, eliminating the need for external balancing components and creating a cleaner, more streamlined design. Engineered for easy adjustment and maintenance, the CTS Loader is ideal for facilities replacing older loading systems or operating in applications where maximizing available space is critical. Its 360-degree rotation capability allows loading on either side of the loading bay, providing greater flexibility and improved loading efficiency. The durable carbon steel and aluminum construction, combined with low-temperature fluorocarbon seals, ensures long-term reliability in demanding petroleum and liquid transfer applications.
