True Drop-In Compatibility
Drop-In Compatibility Details
Mechanical match
The LONGWELL LWAE3G-300-Cold-Chain matches the Sanyo Denki San Ace Cold Storage 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-300-Cold-Chain accepts the same 0–10 V analog speed reference, PWM (1 kHz), and Modbus RTU (RS485) control signals as Sanyo Denki San Ace Cold Storage. Default Modbus register map is compatible with the Sanyo Denki ecosystem; LONGWELL provides a free Modbus map cross-reference for BMS integration. Sanyo Denki-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-300-Cold-Chain sits within 2–3% of the Sanyo Denki San Ace Cold Storage 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 58% vs 60% for Sanyo Denki (2 pp delta at peak). In typical part-load HVAC duty, the gap narrows to within 1 pp.
Typical Applications
The LWAE3G-300-Cold-Chain is widely deployed across Japan convenience store cold storage, display case retrofit. Common application categories include:
- Japan convenience store
- Cold display
- Reach-in cooler
Particularly suited for Japan convenience store cold and frozen display retrofit.
