Founded in 2003, but with product development roots stemming back to 1993, Ventech manufactures mobile heating solutions that incorporates its patented Liquid Heat Generator “LHG” technology.

Ventech is based in Wixom, Michigan, a suburb of Metropolitan Detroit. The tri-county area of Metro Detroit covers almost 2,000 square miles. The area is populated with over 250,000 businesses, many (if not most) somehow related to the auto industry.

The close proximity to the hub of this great industry affords Ventech to stay abreast of new developments, technologies, and customer-needs.

Ventech’s modern facility includes R&D and manufacturing. All final products are assembled and shipped from our Michigan headquarters.

Ventech Liquid Heat Generator (LHG)

Ventech produces a revolutionary innovative mobile heater, the Liquid Heat Generator (LHG). The LHG is designed for portable or mobile applications where an engine or motor is already available. The LHG generates heat quickly, abundantly and efficiently through a proprietary, innovative technology. Ventech is pursuing a series of strong markets including transportation and commercial vehicles, as well as consumer products.

There are five basic problems with today’s vehicles:

  • They take too long to heat a vehicle. Even though heaters have been used in vehicles for almost 100 years, there has been almost no improvement in the time required to heat a passenger compartment.
  • Inadequate source of heat. As engines become more efficient, the waste heat available to be used in heating the cabin is insufficient.
  • Financial Cost. The auxiliary devices used to heat vehicles and cost of the fuel they use is significant.
  • Environmental Impact. Heaters increase fuel consumption and emissions. New energy sources are needed to mitigate environmental problems associated with fossil-fuel based energy sources.
  • Inflexible. Fuel-fired and electric heaters have been used for the heating needs of special mobile units such as power washers, portable showers and temporary shelters. However, fuel-fired and electric heaters are inflexible, complex, ineffective, inconvenient and hazardous.

The Solution: Ventech’s LHG

The LHG generates heat by means of friction produced by fluid (water, coolant or oil) circulating between two specially designed chambers, one chamber rotating against the other stationary chamber.

Ventech’s patented technology agitates the fluid, creating a molecular frenzy that is over 98% efficient in converting rotational energy to heat energy. Ventech’s innovative technology needs only rotational energy from an engine, generator, wind turbine or other mechanical source to produce heat.

The LHG solves critical heating problems:

  • Creates heat quickly. The LHG produces heat almost instantaneously.
  • Abundant Heat. The LHG produces abundant heat. It is the ideal supplementary heater for vehicles powered by diesel, hybrid and other efficient engines that produce little waste heat.
  • Flexible. The LHG is ideally suited for mobile heating needs. Its compact, simple design has few moving parts. It is not hazardous and can be easily adapted for portable applications.
  • Economical. The LHG is much less expensive than other heaters. Typical large school bus auxiliary heaters costs can exceed $3000 for a dealer-installed system in the aftermarket. A Ventech heater can be installed for less than $2000. Other technologies also experience high maintenance costs due to their complexity and unreliability.
  • Environmentally Friendly. The LHG does not need a separate source of power, so it requires no direct electricity, independent fuel source or combustion. The LHG is rotated by an already- running engine. The engine consumes only a slight increase in fuel only when the LHG is engaged (In the same manner as a vehicle air conditioner) but the fuel savings gained by the reduction in idling time significantly exceeds the fuel cost to rotate the LHG. Furthermore, the LHG typically turns off very quickly after the initial warm-up period.
