Variable Frequency Drives For HVAC
ACH580
The ABB ACH580 is a purpose‑built HVAC drive engineered for smooth, energy‑efficient control of fans, pumps, and compressors in commercial and mission‑critical buildings. Designed for simplicity and reliability, it offers native BACnet communications, intuitive setup, and broad motor compatibility—including asynchronous, permanent‑magnet, and SynRM motors. With built‑in features like harmonic mitigation, safety functions, coated boards, and operation up to 50°C, the ACH580 delivers dependable performance while improving comfort, air quality, and system efficiency across HVAC applications.
ACH580 UL Type 4X/IP66
The ACH580 4X is ABB’s extreme‑duty HVACR drive built for harsh, outdoor, and washdown environments. With a UL Type 4X/IP66 fully sealed enclosure, it withstands rain, heat, cold, salt spray, dust, and UV exposure—making it ideal for cooling towers, rooftop units, exhaust fans, and outdoor pump skids. It includes essential HVACR features like integrated harmonic mitigation, EMC filtering, coated boards, Safe Torque Off (STO), and optional Bluetooth® control, all designed to reduce installation costs and deliver reliable performance right at the equipment.
ACH180 Compact Drive
The ACH180 is ABB’s compact, dedicated HVACR microdrive engineered for fans, pumps, compressors, and cooling towers in OEM and commercial applications. Its space‑saving design, built‑in BACnet and Modbus communication, and intuitive graphical interface make installation and commissioning fast and simple. With support for high‑efficiency motor types (including EC Titanium™), coated circuit boards for reliability, and Safe Torque Off (STO) for enhanced safety, the ACH180 delivers efficient, cost‑effective motor control in demanding HVACR environments.
