ZeroRPM Checklist

The IMS® provides full use of all HVAC and electrical components without the fumes and noise from an idling engine. The system’s automatic delivery of heat, air conditioning, and power for equipment in park (as if the engine were running while the engine is off) means few distractions. A focused operator is a safe and happy operator.

A gallon of gasoline and a gallon of diesel fuel produce 18.95 lbs and 22.06 lbs of CO2, respectively. This translates to more than 31 tons of harmful emissions per double-shift vehicle each year. A fleet of 20 vehicles working 262 days a year could produce more than 4.5 million lbs of CO2 and other harmful emissions over their service lives.

Diesel engines consume 0.9-1.2 gallons of diesel fuel during every hour of idling. When an engine’s RPM gauge is at zero RPM, it consumes 0.0 gallons of fuel per hour, resulting in a typical payback from fuel savings ranging from two to four years.

Every hour an engine idles, it is estimated to create the same wear and tear as 33 miles of driving. Many fleets reduce the payback period by 1/3 or more when maintenance cost reduction and asset life extension are factored into the payback calculation. DPF regenerations are often cut in half and manual regenerations are usually eliminated.
