PowerTech is one of the only generator manufacturers that builds every enclosure, frame, bracket, and custom part in-house. Our advanced fabrication facility includes robotic welding, CNC laser cutting, powder coating, and precise quality control. This ensures every generator fits perfectly and stands up to years of heavy use.
From engineering to parts support, PowerTech is known for unmatched customer service. Their in-house technicians provide troubleshooting, parts ordering, maintenance guidance, and long-term support for thousands of units in service across the country.
Diesel is the most popular choice for heavy duty specialty vehicles. PowerTech diesel generators are built using industrial grade engines known for long life, fuel efficiency, and low maintenance requirements. These generators are ideal for:
Diesel power provides steady torque and long life, making it the perfect match for continuous duty applications.
PowerTech also offers a wide range of gas powered vehicle mounted generators, including compact and quiet enclosed models that work well for smaller vehicles and lighter duty applications. Gas generators are commonly used in:
PowerTech gas engines provide smooth operation, clean electrical power, and excellent value for small to medium commercial loads.
Enclosed generators are fully housed in a sound reduced enclosure built by PowerTech. We offer:
These systems are ideal for public facing applications or vehicles parked near customers.
Open PowerTech generators offer:
These units are often mounted inside service truck compartments or trailer generator rooms where noise is not a concern.
PowerTech serves a long list of industries that rely on dependable mobile power every day. Here are the most common applications:
Food trucks, concession trailers, coffee trailers, ice cream trucks, and mobile kitchens rely on consistent power to run refrigeration, grills, fryers, lights, and POS systems. PowerTech provides quiet enclosed generators that fit in compact spaces and power full commercial kitchens.
Medical vehicles require clean, stable power to protect sensitive equipment. PowerTech custom generators power imaging machines, lab equipment, lighting, computers, climate control systems, and mobile clinics across the United States.
Police, fire rescue, homeland security, and military teams trust PowerTech for mission critical power. These generators support communication equipment, lighting, server racks, air conditioning, and life safety systems.
Experiential marketing vehicles need quiet, clean power for displays, audio systems, LED walls, digital screens, and computers. PowerTech units are built to operate for long hours with minimal noise.
Plumbers, electricians, welders, HVAC technicians, and industrial service trucks use vehicle mounted generators to power tools, pumps, compressors, and worksite lighting.
PowerTech generators are widely used in luxury motor coaches thanks to their reliability, quiet performance, and long engine life.
PowerTech uses a custom engineering process to design the perfect generator for your vehicle or trailer.
We evaluate every appliance, tool, or device on your vehicle to determine the correct power output and best fuel source.
PowerTech engineers examine available space, airflow requirements, compartment access, and weight distribution to design a generator that mounts safely and securely.
Every enclosure, frame, and bracket is laser cut, welded, powder coated, and assembled at PowerTech headquarters. This ensures consistent quality and tight fitment.
All PowerTech generators undergo a multi stage test that includes load banking, vibration testing, electrical verification, and coolant and fuel leak checks.
PowerTech provides full support including technical guidance, maintenance schedules, parts support, and long term service.

Routine maintenance is essential for long term reliability, especially for commercial vehicles that run many hours each week. PowerTech provides:
PowerTech also offers digital resources, engine manuals, and parts ordering through PowerTechParts.com.
