Clean, efficient, regenerative heat for EV buses
A uniquely ideal regenerative heat solution for EV Buses
​
In cold climates, BEV (Battery Electric Vehicle) Buses must maintain a comfortable cabin environment, heat the traction battery, and provide the necessary range to complete their route without anxiety. These are significant requirements, and the industry is discovering that traditional supplemental heating solutions are falling short.​
See our blog: The Electric Bus Heating Dilemma - Part One for a more detailed discussion of traditional solutions.

The Ventech evLHG is clean, "green," super-efficient, and respectful of range.
At Ventech, we have developed an elegant solution based on our proven LHG technology. The evLHG's compact design, ideal regenerative energy source, automated operation, and demand adaptability give it distinct advantages over other supplemental heating options for EV Buses.



The Ventech LHG 700 is the latest in our line of continuously improved liquid-vortex heating devices. It is light-weight and extremely efficient, generating close to 48,000 BTU/hr. at 3,000 RPM of input.
See our blog: How much heat does an LHG generate? for an overview of how much heat an LHG can generate.
​
The LHG does not use mechanical friction or electricity to generate heat. There are no parts rubbing together inside, there is no need for an alternative fuel source, and there is no essential drain on an EV Bus's traction battery. The LHG is extremely efficient, because it uses liquid dynamics to create heat from motion.
See our blog: What is a Toroidal Vortex? for an overview of how the LHG generates heat.​

The LHG is Clean, Efficient
Regenerative Heat for EV Buses​
An LHG adds motion-generated heat directly into the coolant/heating loop, which can then be used to support any of the bus’s heating demands.

The LHG is the solution for adding supplemental heat to an EV Bus.

The Ventech LHG is
available for various
EV Buses.
And as a cleaner & more
efficient heating alternative
for Thomas Built, Blue Bird,
and IC Diesel Buses.
