True Drop-In Compatibility
Drop-In Compatibility Details
Mechanical match
The LONGWELL LWAE3G-1000-EC-Pro matches the Ziehl-Abegg ZAvblue 1000 mounting pattern (M-mount, ISO 9001 plenum-fan footprint) within ±0.5 mm tolerance. Inlet ring diameter, motor shaft height, and electrical termination box position are identical. Drop-in retrofit requires no AHU rework, no plate modification, and no plenum hole resizing.
Electrical & control match
The LWAE3G-1000-EC-Pro accepts the same 0–10 V analog speed reference, PWM (1 kHz), and Modbus RTU (RS485) control signals as Ziehl-Abegg ZAvblue 1000. Default Modbus register map is compatible with the Ziehl-Abegg ecosystem; LONGWELL provides a free Modbus map cross-reference for BMS integration. Ziehl-Abegg-specific proprietary protocols (EC-Control bus / ZA-control) are bridged via a free MODBUS gateway available from LONGWELL Engineering — no BMS reprogramming required.
Performance match
The PQ curve of LONGWELL LWAE3G-1000-EC-Pro sits within 2–3% of the Ziehl-Abegg ZAvblue 1000 curve across the full operating envelope (verified by third-party AMCA 210/211 testing at TÜV and Intertek labs). Wire-to-air efficiency at BEP is 63% vs 67% for Ziehl-Abegg (4 pp delta at peak). In typical part-load HVAC duty, the gap narrows to within 1 pp.
Typical Applications
The LWAE3G-1000-EC-Pro is widely deployed across mega dry cooler, hyperscale cooling tower. Common application categories include:
- Mega dry cooler
- Hyperscale cooling tower
Particularly suited for hyperscale cooling tower and mega dry cooler installations.
