Table of Contents
Long-haul OTR trucking spends 1,800 to 2,500 hours per year on the road and a comparable share parked at rest stops, customer yards and team-driver swaps. Without a parking AC, the only way to keep the sleeper cool is idling the main engine — fuel-expensive, anti-idle-regulated and noisy. Vethy's long-haul truck parking AC line replaces idling with battery-powered cooling.
OTR cooling profile and battery sizing
A typical OTR sleeper run uses 8 to 10 hours of overnight cooling at 25 to 35 °C ambient. A 4×100 Ah AGM bank delivers that on the VS02-PRO with margin. For team operations (24/7 cooling), upgrade to lithium 200 to 300 Ah or pair with shore power.
Recommended models for OTR fleets
- VS02-PRO rooftop parking AC – 12V/24V R410A twin-rotor, flagship sleeper cab cooling.
- VX3000SP split parking AC – 12V/24V split, condenser-evaporator separated.
- VM6000 Max high-power rooftop AC – oversized cabs and double-bunk trucks.
- ZH800 inverter rooftop AC – low current draw for battery-sensitive fleets.
Anti-idle compliance and CSA
30+ U.S. states enforce anti-idle laws. CSA scores tied to idle violations have measurable insurance impact for large fleets. Battery parking ACs are exempt from idle restrictions and don't generate CSA points.
