≤68dB Super Silent — Indoor Data Centre and CBD Hotel Grade, 172KW Prime, WP10D238E200 Triple-Layer Canopy

The CDW215KVA is Jiuan Generator's 215KVA Weichai diesel generator for noise-critical applications — indoor data centres, CBD luxury hotels, private hospitals, and urban high-density residential buildings where standard ≤72dB silent generators exceed local environmental noise ordinances. The Weichai WP10D238E200 six-cylinder HPCR engine delivers 172KW/215KVA ISO8528 PRP prime and 194KW/242KVA standby; the triple-layer super silent canopy holds running noise to ≤68dB(A) at 7m — 4dB below standard-series silent performance.

The Weichai WP10D238E200 genset engine is a six-cylinder turbocharged and intercooled inline diesel with 9.726L displacement, 126×130mm bore and stroke, 17:1 compression ratio, and high-pressure common rail injection with ECU control. Engine gross output is 238kW — 38% above the 172KW prime rating — keeping the engine at 72% of rated capacity under continuous prime load. This derating margin lowers combustion pressure and exhaust turbulence, directly contributing to the ≤68dB(A) noise figure alongside the super silent canopy. Specific fuel consumption is ≤195g/kWh at full prime load.

The 172KW super silent generator CDW215KVA canopy is fabricated from 3.2mm cold-rolled steel with four-layer corrosion treatment — pickling, phosphating, electrophoresis, and high-temperature powder coating. Interior sound attenuation uses a triple-layer composite: 60mm flame-retardant cotton, 30mm rubber damping sheet, and a perforated inner absorption panel, combined with a tertiary exhaust silencer and nine rubber shock isolators — achieving ≤68dB(A) at 7m to satisfy EU residential and data centre plant room noise limits.

The 215KVA ultra silent genset CDW215KVA all-copper brushless synchronous alternator is H-class insulated with ±1% steady-state and ±15% transient voltage regulation, protecting server UPS inputs, MRI scanners, and building automation systems from switching transients during ATS transfer. The SmartGen or DSE ATS controller detects grid failure and restores supply within 3-5 seconds — reconnecting data hall cooling, hotel lifts, and hospital critical loads before battery reserves reach cutoff thresholds.

The Weichai WP10 data center generator CDW215KVA carries a factory-registered ESN (Engine Serial Number) and is load-bank tested at 0%-25%-50%-75%-full prime load and 110% overload before shipment, with test video and PDF load report delivered with every unit. Warranty is underwritten by PICC (People's Insurance Company of China), with air-freight parts worldwide in 3-5 days. The 5-language 150-page maintenance manual, wiring diagrams, and 3D disassembly animation CD support non-professional facility teams at overseas data centre and hotel sites.

5 Core Competitive Advantages

1. WP10D238E200 HPCR ≤195g/kWh + 38% Derating Margin — Lower Combustion Stress, Quieter Engine, Longer TBO
The Weichai WP10D238E200 genset CDW215KVA 238kW gross output powers 172KW prime at only 72% of rated capacity — a 38% derating margin that reduces in-cylinder combustion pressure, lowers structural vibration, and contributes to the ≤68dB(A) final noise figure alongside the triple-layer canopy. HPCR injection achieves ≤195g/kWh specific fuel consumption at full prime load, cutting annual energy cost for continuous-duty data centre and hotel standby cycles.

2. Triple-Layer 3.2mm Canopy — ≤68dB(A)@7m, 4dB Below Standard Silent Series for Noise-Critical Zones
The 172KW super silent generator CDW215KVA 3.2mm steel shell with triple-layer interior — 60mm flame-retardant cotton, 30mm rubber damping sheet, perforated inner absorption panel — combined with tertiary exhaust silencer and nine rubber shock isolators achieves ≤68dB(A) at 7m. This surpasses standard-series silent generators by 4dB, providing compliance margin for indoor plant rooms in data centres, hospitals, and CBD towers adjacent to occupied spaces.

3. ESN Traceability + PICC Insurance Warranty — Independent Quality Underwriting for Engineering Procurement
Every 215KVA ultra silent genset CDW215KVA carries a unique factory-registered ESN (Engine Serial Number) and is load-bank tested at 0%-25%-50%-75%-full prime load and 110% overload before shipment, with test video and PDF load report delivered with every unit. Warranty is underwritten by PICC (People's Insurance Company of China) — a state-backed tier-1 insurer — with air-freight parts reaching most countries in 3-5 days.

4. ATS 3-5 Second Response — Data Centre Uptime and Hotel Operations Maintained During Grid Fault
The 215KVA Weichai diesel generator CDW215KVA SmartGen or DSE ATS controller detects grid loss and restores supply within 3-5 seconds — reconnecting data hall UPS inputs, hotel lifts, hospital HVAC, and emergency corridor lighting before critical systems exhaust battery reserves. After grid recovery, the controller completes a cooling-run delay then shuts down automatically without requiring generator room attendance.

5. 5-Language Manual + 3D Exploded Views + Free Service Tools — Complete Documentation for Overseas Facility Teams
The Weichai WP10 data center generator CDW215KVA ships with a 150-page maintenance manual in five languages (Chinese, English, Spanish, French, Russian), electrical wiring diagrams, a 3D disassembly animation CD, and 3D rendered spare-parts exploded views. Jiuan Generator also supplies complimentary service wrenches and testing meters — reducing maintenance costs and installation barriers for non-professional overseas facility engineers.

FAQ

Q: How does the CDW215KVA achieve ≤68dB(A)@7m when standard silent generators typically reach only ≤72dB?
A: The 215KVA Weichai diesel generator CDW215KVA achieves its super silent rating through two simultaneous strategies: engine-side derating — the 238kW WP10D238E200 runs at 172KW prime (72% of capacity), reducing combustion noise at source — and canopy-side triple-layer construction: 3.2mm steel shell, 60mm fire-retardant cotton, 30mm rubber damping sheet, perforated inner absorption panel, tertiary exhaust silencer, and nine shock isolators. Together these produce the 4dB improvement over standard-series performance.

Q: What procurement documentation does PICC insurance underwriting provide for data centre and hospital projects?
A: The 215KVA ultra silent genset CDW215KVA warranty is underwritten by PICC (People's Insurance Company of China) — a state-backed tier-1 insurer. For data centre and hospital procurement teams that require independent quality certification beyond manufacturer-only warranty, PICC underwriting provides verifiable third-party coverage with an insurance policy available for reference. Air-freight warranty parts reach most countries in 3-5 days, supporting urgent on-site resolution at critical facility installations.

Q: What staged load test records are delivered with each CDW215KVA for facility commissioning audits?
A: The Weichai WP10 data center generator CDW215KVA pre-shipment load-bank test covers six stages: 0%, 25%, 50%, 75%, full prime load, and 110% overload. A continuous test video and a PDF load analysis report are generated for each specific unit by ESN, shipped alongside the generator — providing auditable commissioning documentation for data centre facility managers, hospital engineering departments, and local authority inspections.
