Matched to Sanyo Denki San Ace Cold Storage by impeller size and fan type — LONGWELL model LWAD3G300 ← San Ace Cold Storage. Confirm the mounting footprint against the dimensioned drawing on the model page.

Why Engineers Switch from San Ace Cold Storage to LWAD3G300

4–8× Faster Delivery

15–30 days
vs 8–12 weeks ex-works for Sanyo Denki in 2026. Sample units 1–3 days from stock vs 4–10 weeks.

40–55% Lower Landed Cost

−€600 to −€2,400
per unit at equivalent spec, depending on size and quantity. On a 50-unit FanGrid retrofit, typical CapEx delta is €30k–€120k.

Drop-in Candidate · Same Size Class

LWAD3G300
Same impeller size and control protocol; confirm the mounting hole pattern and inlet ring against the LONGWELL drawing before ordering.

Drop-in compatibility: what matches and what to confirm

Mechanical match

The LONGWELL LWAD3G300 matches the Sanyo Denki San Ace Cold Storage mounting pattern (M-mount, ISO 9001 plenum-fan footprint) per the mounting dimensions on the LONGWELL drawing. Inlet ring diameter, motor shaft height, and electrical termination box position are identical. In most retrofits no plate modification is needed — confirm the mounting dimensions against the LONGWELL drawing before ordering.

Electrical & control match

The LWAD3G300 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. LONGWELL supplies its Modbus RTU register map with the fan so the BMS points can be re-mapped; the register addresses are not identical to the Sanyo Denki map.For ebm-papst-specific bus protocols (EC-Control), ask LONGWELL engineering for the integration options.

Performance match

The measured P-Q curve of every LONGWELL model is on its model page; we check your duty point against it before quoting.

Typical Applications

The LWAD3G300 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.

FAQ

Is LONGWELL LWAD3G300 a true drop-in replacement for Sanyo Denki San Ace Cold Storage?
Same size class and control interface. Confirm the mounting hole pattern, inlet ring diameter and shaft height against the dimensioned drawing on the LONGWELL LWAD3G300 model page before ordering; it accepts the same 0–10 V analog / PWM / Modbus RTU control signals and is offered in the voltages listed in the table above.
How does LWAD3G300 compare on efficiency to San Ace Cold Storage?
LONGWELL does not publish a single peak-efficiency figure for the LWAD3G300. The model page on the selection site gives airflow, static pressure and input power along the curve (measured where marked, nameplate-estimated otherwise), so the efficiency at your duty point follows directly; a test report for a specific model is available from engineering on request.
What’s the 2026 lead time difference?
As of May 2026: Sanyo Denki San Ace Cold Storage requires 8–12 weeks ex-works due to ongoing allocation. LONGWELL LWAD3G300 ships in 15–30 days for orders up to 500 units and 6–10 weeks for 1,000+ unit OEM programs. Sample units ship in 1–3 days from stocked Ø300 mm inventory.
What’s the cost delta?
At equivalent specification (same Ø, same airflow/Pa, same IP, same control), LONGWELL LWAD3G300 typically lands at 40–55% below Sanyo Denki San Ace Cold Storage ex-works pricing. Final pricing depends on quantity, voltage, IP rating, and control protocol options.
What applications is LWAD3G300 typically used for?
LWAD3G300 is widely deployed across Japan convenience store cold storage, display case retrofit. Particularly suited for Japan convenience store cold and frozen display retrofit.
