Nicotra Gebhardt RDH 560 Alternative — LONGWELL RDH-R 560

Looking for an alternative to Nicotra Gebhardt RDH 560? LONGWELL's commercial centrifugal line mirrors the Nicotra naming 1:1 — RDH-R 560 — with identical frame designation, dimensional interchangeability, belt-drive or factory EC-upgrade, AMCA-tested aerodynamics, at 40–55% lower landed cost and 15-day delivery vs 10–14 weeks ex-works Nicotra. This is the single highest-value naming-mirror battle in the commercial AHU segment.

Engineered match verified against Nicotra Gebhardt RDH 560 (also RDH 450) in LONGWELL's cross-brand model library (record: NAMING_MIRROR — RDH-R 560). RDH-R 560 → Nicotra RDH 560 (30,000 m³/h, 2,200 Pa); RDH-R 450 → RDH 450 (18,000 m³/h, 1,800 Pa). Full RDH-R range covers 280–630.

Why Engineers Switch from RDH 560 to RDH-R 560

4–8× Faster Delivery

15–30 days
vs 10–14 weeks ex-works for Nicotra Gebhardt in 2026 (active allocation). Sample units 1–3 days from stock.

40–55% Lower Landed Cost

−40 to −55%
per unit at equivalent spec. On a multi-unit AHU / fan-grid program the CapEx delta scales fast.

Belt or EC-Upgrade Path

25–40%
fan-energy saving available via the factory EC-drive (-K) variant vs the standard belt-drive Nicotra arrangement.

Drop-In Compatibility Details

Frame & dimensional match

LONGWELL RDH-R 560 carries the identical backward-inclined frame designation as Nicotra RDH 560 — scroll dimensions, inlet cone, outlet flange, and shaft/bearing centres match 1:1, so it drops into the same AHU section, the same belt-guard, and the same pedestal without rework.

Drive & motor options

LONGWELL ships the RDH-R 560 belt-driven with a selectable IE3 / IE4 motor to match the existing Nicotra RDH 560 drive train, and offers a factory EC-upgrade variant (the -K suffix) that replaces the belt with a direct EC drive for variable-volume AHU and 25–40% fan energy savings.

Performance match

The aerodynamic curve of LONGWELL RDH-R 560 tracks the Nicotra RDH 560 within AMCA 210 test tolerance across the operating envelope (third-party tested). RDH-R 560 → Nicotra RDH 560 (30,000 m³/h, 2,200 Pa); RDH-R 450 → RDH 450 (18,000 m³/h, 1,800 Pa). Full RDH-R range covers 280–630. Performance is matched at the published duty point, with LONGWELL's documented cross-brand library backing the selection.

Typical Applications

The LONGWELL RDH-R 560 is widely deployed across high-pressure industrial AHU and process ventilation. Common application categories include:

  • High-pressure industrial AHU
  • Process & dust extraction
  • Library / archive HVAC

RDH is the high-static backward-inclined workhorse; LONGWELL RDH-R 560 / 450 mirror it 1:1 for high-resistance systems.

FAQ

Is LONGWELL RDH-R 560 dimensionally interchangeable with Nicotra RDH 560?
Yes. LONGWELL mirrors the Nicotra commercial naming 1:1 — RDH-R 560 carries the same backward-inclined frame designation, scroll dimensions, inlet/outlet geometry and shaft centres, so it fits the same AHU section and pedestal. RDH-R 560 → Nicotra RDH 560 (30,000 m³/h, 2,200 Pa); RDH-R 450 → RDH 450 (18,000 m³/h, 1,800 Pa). Full RDH-R range covers 280–630.
Does LONGWELL offer an EC-upgrade for the RDH 560?
Yes — alongside the belt-drive IE3/IE4 standard build, LONGWELL offers a factory EC-drive variant (the -K suffix, e.g. RDH-R 560) that replaces the belt with a direct EC drive for 25–40% fan energy saving and BMS speed control.
What's the 2026 lead-time and cost difference?
LONGWELL RDH-R 560 ships in 15–30 days vs 10–14 weeks ex-works for Nicotra RDH 560 under allocation, and typically lands 40–55% below Nicotra ex-works pricing at equivalent spec. Samples ship in 1–3 days.
Why does LONGWELL use the same model naming as Nicotra?
LONGWELL's commercial centrifugal line was engineered to be a 1:1 functional and dimensional mirror of the Nicotra Gebhardt range, so specifiers can cross-reference by frame designation directly (AT, DD/DDK, RDH/RDH-R, RZR/RLM E, ADH). It removes re-selection effort — the LONGWELL part is the same size, same duty, same AHU section.
Can I get the full Nicotra-to-LONGWELL commercial cross-reference?
Yes — the complete AT / DD / RDH / RZR / ADH naming-mirror table is in the cross-reference, and the Commercial Blower Portfolio Pack covers the full line. Send the Nicotra model + duty point to sales@zjlongwell.com for a verified equivalent and sample.
