Curb Adapters

 

RTU Curb Adapters

A curb adapter provides an efficiently modified interface between an HVAC rooftop unit (RTU) and the rooftop ports or holes that feed the heating and air conditioning to and from the building. The rooftop ports are built into a raised external assembly called a curb. Many of these rooftop HVAC curbs were originally set into the roof to accommodate old HVAC units that are either no longer in production or no longer the best choice for the building’s current needs.

Our curb adapters solve that problem.

We use advanced design and engineering technology to create components that route the curb discharge and intake ports to their matching ports on the HVAC unit as precisely as humanly possible for maximum heating and cooling efficiency. No matter what make or model of RTU you want to install on your rooftop curb, we can build a curb adapter to make it possible!
