True Drop-In Compatibility
Drop-In Compatibility Details
Mechanical match
The LONGWELL LWBE3G-560-EC matches the Nicotra Gebhardt RDP 560 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 LWBE3G-560-EC accepts the same 0–10 V analog speed reference, PWM (1 kHz), and Modbus RTU (RS485) control signals as Nicotra Gebhardt RDP 560. Default Modbus register map is compatible with the Nicotra Gebhardt ecosystem; LONGWELL provides a free Modbus map cross-reference for BMS integration. Nicotra Gebhardt-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 LWBE3G-560-EC sits within 2–3% of the Nicotra Gebhardt RDP 560 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 89% vs 89% for Nicotra Gebhardt (0 pp delta at peak). In typical part-load HVAC duty, the gap narrows to within 1 pp.
Typical Applications
The LWBE3G-560-EC is widely deployed across FanGrid arrays, industrial AHU, large CRAH. Common application categories include:
- FanGrid arrays
- Industrial AHU
- Large CRAH
Particularly suited for FanGrid arrays for US data center CRAH retrofit.
