In 2024, the U.S.-based company launched a major upgrade and overhaul of the Unist APEX™ fluid controller, encouraging can makers to transition from the legacy SPR-2000 system and older APEX models — a move that significantly improves precision, automation, and ease of use. With full support for the SPR-2000™ ending no later than 2028, transitioning to the updated APEX™ now will eliminate production risks before replacement parts become unavailable.

The next generation APEX™ controller represents a major step forward in Unist’s history of innovation. Unist first introduced its Cupping Coil Lubrication System in 2000, built around the internally fed Uni-Roller® Type S and SPR-2000™ control system. With hundreds of systems operating 24/7 worldwide, Unist has built a strong reputation for durability and precise lubrication application. In 2018, Unist released the Uni-Roller® S2, replacing the Type S and delivering superior consistency, waste reduction, and seamless integration with Unist’s fluid supply systems. Now, the redesigned APEX™ is set to replace both the SPR-2000™ and older APEX™ models, bringing next-generation automation and control to can makers worldwide.

The APEX™ system delivers precise lubricant volumes through its positive displacement pump, ensuring consistent performance under varying conditions. Unlike pressure-based systems, which fluctuate due to pressure changes, this pump dispenses an exact volume per cycle, maintaining accuracy across different viscosities and temperatures. This results in a more controlled lubrication process, optimized for efficiency and repeatability, key for high-speed cupping press operations. By eliminating inconsistencies caused by pressure fluctuations, the APEX™ significantly reduces fluid waste while ensuring precise lubricant application to every coil.

The redesigned APEX™ also introduces an Allen Bradley HMI, replacing the push-button interface and basic text screen of the SPR-2000™. Navigation is more intuitive, real-time monitoring is clearer, and troubleshooting is significantly faster. Automatically set up jobs by inputting fluid density, eliminating manual estimations and improving dispensing accuracy, which was previously a time-consuming process. With the ability to store and recall up to 20 jobs, operators can quickly switch between settings, reducing downtime and increasing efficiency.

One of the most significant upgrades is the real-time active monitoring system, which continuously tracks fluid flow, pressure, and overall system performance. The APEX™ can detect inconsistencies in lubrication, helping to prevent over- or under-lubrication, which helps reduce waste and improve process stability. Built-in alerts notify operators of low fluid levels, pressure drops, or system errors, allowing for immediate corrective action. When issues arise, the APEX™ features a built-in Pump Output Test, a diagnostic tool that compares the target dispense volume, flow meter measurement, and actual dispensed volume—ensuring the pump is operating correctly. This feature was not available on the SPR-2000™ or the previous APEX™ model and provides a significant advantage in troubleshooting and maintenance.

With the SPR-2000™ fully obsolete by 2028, can makers who wait to upgrade may face extended downtime due to unavailable parts. By upgrading to the new APEX™, can makers eliminate these risks, reduce fluid waste, and future-proof their lubrication process with the latest advancements in control technology.

Don’t wait until obsolete parts disrupt your production—make the switch to APEX™ today.
