USA Diesel LHG (Liquid Heat Generator)
The LHG, using advanced technology, provides extremely rapid engine warmup. The system quickly and efficiently brings an engine up to and maintains its proper operating temp, dramatically reducing idling warmup and cold run time. This results in improved fuel economy, reduced emissions, lower maintenance costs and significantly reduced engine wear.
As an added benefit, the system also provides extremely rapid window de-icing/defrosting during freezing temp operation. With an LHG installed, there's no more shivering and waiting 20 minutes for a rig to heat up. During testing in freezing conditions an LHG equipped 6.7L rig was blowing hot air into the cabin withing a couple short minutes and achieved full operating temp in less than 7. A stock rig in the same test took around 22 minutes! The difference is dramatic. With the average commute currently estimated at around 27 minutes, it's a significant revelation. In other words, on a typical 27 minute commute in freezing temps, a non LHG rig is "running dirty" 81% of the time. That's exactly what leads to DPF clogging, regen cycles, more contaminants moving through the engine and excessive engine wear. Running cold means damage. This is true regardless of whether the weather is cold outside or not. Running an engine below it's ideal operating temp causes problems, especially on today's modern vehicles that are loaded down with failure prone emissions equipment. The LHG is a 50 state LEGAL way to solve a legitimate problem.
Unlike older attempts to address the issue that used flame, diesel fuel or exhaust gasses to generate heat, the LHG uses coolant and the magic of fluid dynamics. It's serpentine belt driven and coolant is plumbed in and out of the unit. The LHG does its job from there. An advanced smart controller monitors conditions and ensures proper operating temp. is maintained. Consistently running an engine at it's optimal temperature promotes far cleaner, more efficient combustion. (dramatically reduced DPM levels). The result? Dramatically fewer regen cycles and a dramatically extended lifespan for your Diesel Particulate Filter (DPF).
The liquid heat generator (LHG) is capable. It instantly adds 8-16kW (27,000 - 55,000 BTU) of additional heat to your engine coolant circuit and heater core based on engine RPM. The system is fully automated and a smart control module engages and disengages the unit based on coolant temp, load and operating conditions. It works when it needs to and shuts off when it doesn't. The controller even monitors vehicle usage. If the truck hasn't been ran/driven for an extended period of time the smart controller will prompt the LHG to initiate a self-cleaning cycle. It's smart.
These units perform better, have fewer maintenance needs, cost less and are far easier to install than antiquated "burner" based solutions. Installation of an LHG can be completed in a couple hours with a set of basic tools.
