Overview#
The Hipower HMW-310 is a 310 kW diesel standby generator powered by an MTU 1600-series 10-cylinder engine. Manufactured in Olathe, Kansas, it delivers the full mission-critical specification stack — NFPA 110 Level 1 certification, IBC seismic Zone 4 compliance, and 200 mph wind rating — with an MTU engine rated for 30,000+ hours between major overhaul. EPA Tier 4 Final emissions certification makes it deployable throughout California and CARB-regulated regions.
The HMW-310 targets the upper range of the 300 kW class, providing additional capacity headroom over the HMW-270 for facilities with peak HVAC compressor starts, high-inrush UPS systems, or planned load growth. At this power level, the unit is a common choice for 500-800 ton data center cooling plants, large outpatient surgical centers, and mid-size telecom central offices.
MTU Engine Platform#
The MTU 1600 series is a 10-cylinder V-configuration diesel engineered by MTU (Rolls-Royce Power Systems) for continuous and standby duty in the most demanding environments. With approximately 16 liters of displacement and turbocharged-aftercooled induction, the 1600 series delivers exceptional power density with a TBO (time between overhaul) exceeding 30,000 hours — the highest in the commercial standby generator segment at this power class.
Facilities engineers specify MTU for its transient response characteristics: the engine absorbs large step-load transitions (motor starting, UPS switchover) with minimal frequency deviation, meeting NFPA 110 Type 10 requirements without stress events that shorten engine life. The SCR-based Tier 4 Final system maintains full combustion efficiency, unlike EGR alternatives that impose fuel consumption and oil contamination penalties.
Mission-Critical Design#
The HMW-310's certification portfolio addresses the full range of NorCal permit requirements:
- NFPA 110 Level 1, Type 10: Life-safety standby, 10-second pickup — required for hospital critical branches and data center critical UPS feeds
- IBC Seismic Zone 4 certified: Qualifies for installation throughout California's high-seismic regions without additional engineering review
- 200 mph wind rating: Exceeds requirements for all US wind zones
- Dual-wall sub-base tank option: Simplifies NFPA 30 and SPCC secondary containment compliance in urban installations
- Remote diagnostics via MTU DiASter: Optional SCADA integration for real-time engine health monitoring and predictive maintenance trending
Paralleling Capability#
Isochronous load sharing allows HMW-310 units to operate in synchronized multi-generator configurations. A pair in N+1 provides 310 kW critical capacity with 100% redundancy. Three units in N+1 cover 620 kW with a spare. Hipower's paralleling interface is compatible with standard automatic paralleling switchgear platforms from Asco, Russelectric, and Kohler Power Systems, reducing integration cost versus proprietary paralleling solutions.
Service and Maintenance#
MTU's 30,000-hour major overhaul interval extends two to three times longer than competing Tier 4 Final diesel engines in the 300 kW class. For a typical critical facility running monthly 4-hour load bank tests, that translates to a 60-year major overhaul interval — effectively the life of the building.
Tier 4 Final SCR maintenance requirements for the HMW-310: DEF purge at every shutdown, DEF quality check at oil changes (target 32.5% urea concentration), SCR catalyst inspection at 8,000 hours, and high-pressure fuel system filter changes at 500-hour intervals using MTU-spec elements only.
Our Service Experience#
OnPoint Generators services MTU-powered generator sets across Northern California, including HMW-310 deployments at data center campuses and hospital systems in the Bay Area and Central Valley. Our technicians hold MTU certifications and carry factory diagnostic software for the 1600 series — essential for SCR system diagnostics, fuel system fault codes, and emission compliance verification that general-purpose generator mechanics cannot perform.
