Webasto Thermo & Comfort North America has developed an integrated aftermarket HVAC system for medium-duty applications, including the Ram ProMaster and similar work vehicles.

Based on its London heating, ventilation and air conditioning product, the system offers up to 32,500 Btus per hour of cooling capacity and 44,500 Btu/h of heating capacity.

The Webasto system can be installed in the driver’s compartment bulkhead area with conditioned air directed rearward. This allows for ease of installation without compromising valuable cargo space, the company said.

The new product ties into the vehicle’s existing in-line condenser and compressor for cooling. The London is equipped with high-efficiency blowers that deliver constant airflow and ensure a long service life.

For warmer climates, Webasto has introduced the Extreme Climate HVAC aftermarket system. This system is an independent HVAC kit that shares the same components as the London tie-in configuration, and adds an auxiliary-engine driven compressor, a compressor mount kit and a roof-mounted low-profile condenser.

The system for the Ram ProMaster is Webasto’s first vehicle-specific application for the London unit, the company said. It has custom control units, air vents and ducts to perfectly fit within the cargo space.
