About karlesk
karlesk makes climate equipment for vehicles that stay on the road, on the water and off the grid: diesel air heaters, portable diesel heaters and battery-powered parking air conditioners.
What we make
- Diesel air heaters — 2.5 kW and 5 kW, 12V and 24V, for cars, vans, RVs, boats and truck cabs.
- Portable diesel heaters — all-in-one 5–8 kW units for tents, cabins, garages and job sites.
- Parking air conditioners — 12V and 24V rooftop and split units from 2000 to 3500 W that cool the cab from the battery.
Who we work for
Truck drivers and fleets, van lifers and RV owners, boat owners, farmers and machinery operators — anyone who needs heat or cooling while the engine is off.
