Frazer, Ltd. is the nation's leading builder of generator powered EMS modules, serving Fire and EMS organizations across the country for over 25 years. And though the EMS industry has grown substantially from when we started,one thing that never changes is our unwavering commitment to providing you with the power to do more with your vehicles that you ever thought possible. The benefits of having your module powered by a separate 5.5kW commercial generator are vast. Independent, unrestrained power to the patient compartment and emergency systems gives you more power than ever. Ours is a truly modular power system that does not interfere with the truck battery, extending the life of your chassis and your module.
