Retrofit Zoning at Arzel

Our unique damper options make Arzel Zoning a leader in retrofit zoning. We develop products with contractors in mind, allowing us to zone more existing buildings. Our modern pneumatic zoning systems are fast and easy to install because there’s no extra wiring or transformers to power the dampers. You can count on our reliability, too. We have a test damper that has been continuously opening and closing for years and has up to 23 million cycles. This reliability is why the industry’s best warranty covers Arzel zoning systems.

Retrofit Damper Options

When ductwork is accessible, our EzySlide damper installs through a simple cut-in. The round EzySlide dampers have a sticker template that makes retrofit installation a breeze. Put the sticker on the duct, cut out a triangle on the lines, and insert the round EzySlide. Rectangular EzySlide dampers require a rectangle cut-in; installation is just as simple. Watch our EzySlide installation demos to see how it works.

When there’s access to the main trunk but not the branches, our round InsertaDamper can be inserted through the elbow and into the takeoff. A spring-loaded grip also makes InsertaDamper an excellent choice for light commercial applications where the damper will sit in a vertical duct.

When you have little access, our round EzyFit dampers fold like a taco and insert through the boot into the branch. These dampers are an excellent choice when homeowners plan to finish their basement and cover the ductwork with drywall. EzyFit dampers are secured by a magnet, so they require metal ductwork.

If none of these damper options work, our RegiDamper fits directly into the register boot. This makes zoning possible in retrofit applications where you can get a damper into almost every space, but there’s just one area without reasonable access.

Residential Retrofit Panel: HeatPumPro

For residential retrofits, we recommend the HeatPumPro for most applications. It is not just for heat pumps, either! HeatPumPro is compatible with conventional furnaces, air conditioners, heat pumps, dual fuel, and multi-stage equipment. This feature-rich panel includes leaving air temperature protection and an outside air sensor that handles heat pump changeovers. HeatPumPro also includes zone weighting, a feature that enables staging based on the percentage of ductwork that is called.

Light Commercial Retrofit Panel: AirBoss

The AirBoss is our go-to panel for light commercial retrofits. It can be configured for up to 8 zones and is compatible with conventional and two-stage equipment, heat pumps, and dual fuel. AirBoss includes a master zone control feature that allows the setback of the entire building using one programmable thermostat. It also eliminates the need for two-stage thermostats by using a delay. AirBoss includes leaving air temperature protection, too.

The Panel for Budget-Conscious Jobs: MPS

Sometimes, you don’t need all the bells and whistles, and the MPS panel is excellent for those applications. This economical panel gives you the quality of Arzel Zoning with all our damper options. MPS has some limitations: it is only compatible with single-stage equipment and does not offer leaving air temperature protection.
