Espar’s Airtronic Air Heaters work independently of the vehicle’s heating system and are not tied into the vehicle coolant lines. The Airtronic heaters can be mounted independently  in the vehicle cab or in a separate compartment with ducting to route the warm air into the passenger compartment.

Cargo kits are available for mounting the Airtronic heaters in a cargo area of a truck to protect cargo from freezing or heating the work area of service vehicles.

The following are low and high output settings on standard Espar Airtronic models. Higher capacity models are available. Contact us for more details.
