Power Options for Frazer EMS Vehicles

There’s no one-size-fits-all solution when it comes to powering emergency vehicles like ambulances. Every fleet manager faces the challenge of balancing cost, maintenance, and environmental impact. Emergency Transportation Associates (ETA) is dedicated to aiding you in your analysis of power option comparisons, providing valuable insights to facilitate informed decision-making.

Frazer Ambulance Power Options

Frazer offers three power options that vary widely, each with distinct advantages. The MEPS System utilizes engine-mounted generators for reliable power with low maintenance. The Onan Generator offers independent power sources for fail-safe operation and extended vehicle lifespan. Harrison Hydragen’s hPower manages idle mitigation and battery charge for fuel savings and environmental benefits. Understanding these differences will help meet your specific needs, ensuring optimal performance, longevity, and efficiency for every operation with this diverse array of emergency vehicle power options.

The MEPS System uses an engine-mounted generator to produce 120V AC power, requiring the truck chassis to be operational. It provides reliability, durability, and low maintenance, making it an excellent choice for cost-effective solutions with increased storage space.

ONAN: Independent Generatorpower option for frazer ems vehicles: reeves onan unit

The Onan Generator functions as a standalone power source, separate from the chassis engine. It offers fail-safe power, quiet operation, and quick swap-out capability, which is ideal for extending the lifespan of truck chassis through idle reduction.

Harrison Hydragen’s hPower system operates through an inverter-lithium ion battery pack system. It smartly switches between idle mitigation and battery charge, reducing fuel costs and excessive engine wear and promoting environmental cleanliness.

MEPS PMI: Power Management Interfacepower option for frazer ems vehicles: meps pmi

MEPS PMI features idle-reducing technology, enabling the under-hood generator system to power onboard electrical equipment while replenishing battery banks. It ensures continuous mobile electric power, reducing chassis wear and tear, fuel consumption, and idle time.
