Leveraging the powerful performance tiering capability of ST chips, Hunan Leading Technology has launched two differentiated controllers to precisely match various customer application scenarios:

1.SL-T21&22/T/Q Cost‑Effective Version
Equipped with mid‑frequency STM32 chips and the ST Purple Ming Platform V13.0, this model delivers full‑featured basic intelligent control, including precise liquid level adjustment, multi‑layer pump protection, and local fault alarms. It is ideal for single‑pump sewage lifting equipment in residential villa basements, sunken small apartments, and small shops — offering a cost‑effective and reliable choice.

        2.SL31&32/F/Q Flagship IoT Version
        Featuring high‑performance 800MHz STM32 main control chips with hardware acceleration units and the upgraded ST Purple Ming Platform V14.0, this version supports dual‑pump alternation, variable frequency speed regulation, cloud remote connection, and multi‑device cluster management. It is suitable for large commercial complexes, hotel kitchens, multi‑unit pump stations in underground parking lots, and small integrated municipal sewage lifting stations — meeting the intelligent batch management needs of engineering projects.

        Both models share the same underlying ST chip architecture to ensure consistent stability standards. Whether for household essential use or mass supporting in commercial engineering projects, they deliver uniform and dependable intelligent control performance. We provide one‑stop semiconductor intelligent control solutions for sewage lifting equipment manufacturers, engineering service providers, and end users.
