IntelliThaw® PV400 Freeze Prevention System

engenity, LLC, has developed a line of freeze-prevention heating jackets for Mann+Hummel's ProVent® 400 crankcase ventilation filter. When mounted in exposed locations, ProVent filters are susceptible to freezing and gelling of the fluids within. 

The IntelliThaw PV400 is an all-in-one, easy-to-install solution to this problem. The IntelliThaw PV200 completely encloses the filter, and can safely raise its interior temperature from −50°C to 10°C (−58°F to 50°F) in only 5 minutes, using only power from the engine battery.

IntelliThaw is part of engenity's ThermEvolve® line of engine heating solutions. ThermEvolve systems are the industry's only solution for engine component freeze-ups that do all the following:

  • apply heat only when it's needed, in order to save battery power,
  • heat up fast (within 5 minutes under most conditions),
  • allow easy installation in the field with minimal use of tools,
  • eliminate guesswork and chance in specifying components and temperatures,
  • allow programming to any setpoint temperatures, and
  • last for years free of maintenance.
