Overview#
The Hipower HMW-1730 is a 1,730 kW diesel standby generator and the top model in Hipower's MTU 12V4000 configuration. Built in Olathe, Kansas, the HMW-1730 delivers 1.7 MW of critical standby capacity from a single enclosure powered by a 12-cylinder, approximately 52-liter diesel engine with a 30,000-hour TBO. NFPA 110 Level 1, IBC seismic Zone 4, and 200 mph wind certification are standard. EPA Tier 4 Final and CARB compliance make it the preferred single-unit 1.7 MW generator for Northern California's strict emissions environment.
At 1.7 MW, the HMW-1730 serves the largest single-unit applications before the step to 16-cylinder 4000-series power. A single HMW-1730 can cover an entire large hyperscale data center row, an entire hospital essential electrical system, or a military base primary generation requirement.
MTU Engine Platform#
The MTU 12V4000 series at 1,730 kW represents the top of the 12-cylinder configuration's output range. Approximately 52 liters of displacement in a V-12 arrangement with turbocharged-aftercooled induction generates 1.7 MW with the substantial torque reserve required for reliable step-load acceptance at this output scale. MTU (Rolls-Royce Power Systems) developed the 4000 series for naval, military, and heavy industrial applications where sustained full-load duty cycles over decades are routine operating conditions.
The 4000 series' military heritage is directly relevant to critical facility applications: repeated full-load cold starts, extended sustained duty at 100% load, and minimal performance degradation over 30,000 hours of operation. The SCR-based Tier 4 Final system maintains combustion efficiency throughout this service life.
Mission-Critical Design#
Standard certifications for the HMW-1730:
- NFPA 110 Level 1, Type 10: Full-load pickup within 10 seconds — mandatory for hospital essential systems and hyperscale data center critical UPS feeds at 1.7 MW
- IBC Seismic Zone 4 / SDS 2.0: Pre-certified for California seismic installations — critical for hospital OSHPD compliance and NorCal data center AHJ permits
- 200 mph wind rating: Qualifies for all US geographic wind exposure zones
- Dual-wall sub-base tank: Integral secondary containment for NFPA 30 and EPA SPCC
- MTU DiASter SCADA: Enterprise remote monitoring, predictive analytics, fuel trending, and CARB compliance support
Paralleling Capability#
The HMW-1730 is designed for campus-scale paralleling architectures. Two units in N+1 deliver 1.73 MW critical capacity with full standby reserve. Larger campuses use three to six HMW-1730 units in N+1 for 3-9 MW of aggregate critical standby with distributed redundancy. At this output level, automatic paralleling switchgear must be specified for the 1.73 MW per-unit bus contribution — confirm with the switchgear manufacturer for appropriate frame sizing.
Service and Maintenance#
MTU 12V4000 maintenance schedule: 500-hour oil and fuel filter changes (52L displacement — confirm oil system volume in the operator manual), 1,000-hour air filter, 4,000-hour DEF injector inspection, 8,000-hour SCR catalyst inspection, 30,000-hour major overhaul. Fuel polishing at 6-month intervals is mandatory at this output level. MTU 4000-series service requires technicians with specific 4000-series training distinct from 1600/2000-series certification. Major overhaul events at 1.7 MW require coordinated planning with facility operations to maintain redundancy during the service window.
Our Service Experience#
OnPoint Generators provides MTU-certified service for large-frame Hipower HMW installations in Northern California. For HMW-1730 operators: our team coordinates maintenance scheduling within facility redundancy windows, provides NFPA 110 Level 1 annual compliance testing and documentation, fuel polishing, and emergency dispatch. At 1.7 MW, generator reliability is a campus-wide critical systems dependency — having local certified expertise on call is a key operational risk management element.
