CAT CLASS: HQ-10737

300-600 kW Towable Diesel Generator

The 300-600 kW towable diesel generator class delivers industrial-grade temporary power for facilities requiring uninterrupted electrical service at near-megawatt scales. These units support critical infrastructure including hospitals, data halls, manufacturing plants during maintenance turnarounds, and projects requiring substantial three-phase distribution. Due to size and weight, equipment in this band ships on lowboy trailers rather than towing behind pickup trucks.

Spécifications clés

Spécification	Plage typique	Signification
Power output	300-600 kW continuous rating	Sustains large facility loads including HVAC, lighting, servers, and industrial process equipment simultaneously.
Fuel capacity	500-1,000 gallons onboard	Extended runtime between refueling events; typical consumption 15-30 gallons per hour at full load.
Voltage configuration	480V three-phase / 208V / 240V options	Matches commercial and industrial distribution requirements; switchgear integrates with building mains or temporary panels.
Transport method	Lowboy or flatbed trailer	Weight and dimensions exceed DOT limits for conventional towing; requires commercial hauling.

Comment choisir

The 300-600 kW band fits projects demanding utility-scale temporary power but falling short of multi-megawatt installations. Hospital emergency backup, telecommunications hubs, mid-sized manufacturing shutdowns, and large construction sites with substantial electrical loads justify this class. For smaller commercial jobs, retail centers, or mid-sized events, the 150-300 kW Towable Diesel Generator band provides adequate capacity with simpler logistics. When powering full industrial complexes, campus-wide outages, or substations, the 1,250+ kW Towable Diesel Generator becomes necessary despite higher transport and fuel costs.

Ce que cette taille peut gérer

Hospital emergency power during planned utility maintenance or grid failure
Data center backup power for continuous server and cooling operation
Refinery or chemical plant turnaround powering temporary lighting, tools, and process equipment
Large-scale outdoor event with multiple stages, lighting towers, and vendor services
Construction site main power distribution for high-rise or infrastructure projects
Mobile command centers and disaster relief field hospitals

Sécurité et opération

Load bank testing and commissioning verify rated capacity before connecting critical systems
Exhaust placement and carbon monoxide monitoring required due to substantial combustion byproduct volume
Ground fault protection and overcurrent devices integral to distribution; qualified electricians handle connections
Soundproof enclosures standard in residential or noise-sensitive zones; dBA levels vary by model and load

Transport et logistique

Ships on lowboy or flatbed trailer; weight typically 8,000-20,000 lbs depending on fuel load and enclosure
Requires commercial CDL hauling in most jurisdictions; escort vehicles may be required depending on state regulations
Crane or forklift often needed for positioning and ground preparation at final location

Alimentation

Diesel fuel supply via onboard tank; bulk fuel delivery scheduled for multi-day or week-long operations
Camlock, pin-and-sleeve, or bolted bus bar connections to temporary or permanent distribution gear
Automatic transfer switch (ATS) integration common for standby applications in critical facilities

Questions fréquentes

How long can a 300-600 kW generator run continuously?

Runtime depends on load and fuel capacity. At 75% load, a unit with 800-gallon tank typically runs 36-48 hours before requiring refueling. Continuous operation for weeks is common with scheduled fuel delivery.

What distribution equipment is needed with this generator size?

A main distribution panel or switchgear rated for 480V three-phase, coordinated overcurrent protection, and either manual or automatic transfer switching if integrating with building electrical systems. Qualified electrical contractors design and install the distribution.

Can this size generator power an entire hospital?

A 300-600 kW unit can support critical loads (ER, ICU, life safety systems) in a small to mid-sized hospital. Larger facilities often require paralleled generators or units in the 1,250+ kW range to cover full campus demand.
