Proper Zoning - High Velocity

By following these tested guidelines for zoning the SpacePak system you will avoid coil freeze-ups, air noise, damper failures, etc. Right now zoning is accomplished in the main plenum, but testing and product development is currently underway for zoning of individual outlets, which will involve mini 2" dampers which will be installed right at the plenum take off. As soon as this new technology is available, you will see it here.

Follow Manual J Protocal

size the system correctly taking note of solar gain from glass and sun exposure
perform a comfort survey to see which areas will have more people and need more airflow

Be generous when grouping rooms in to zones

no more than 3 zones
every zone should consist of multiple rooms with the same demand for air. Like bedrooms and living areas.

Use 3.5 outlets per zone, per ton minimum

You may increase the number of outlets per zone/ton
increasing the number of outlets per zone provides additional points of relief
example 2-ton, 2-zone system will have a minimum of 7 outlets per zone

Do not use a bypass damper

high velocity systems run with supply air temps much lower than typical systems
bypassing air back to the return will cause coil freezing

Use dampers on the plenum only

install a zone damper on each plenum going to each zone
letting up to 10% blow-by in closed (off) zones will keep pressure and air noise acceptable
allowing the blow-by in closed zones also reduces damper stress

Arzel® - Zoning Equipment

High velocity pneumatic zoning equipment. Zone control panels include transformer and are a proven, basic zoning panel. Dampers are simple to install and are connected to the zone panel by air lines, not wiring. Use PVC tubing for installation outside of ductwork. Use Plenum tubing for installation inside of ductwork. Need more zones for other applications, or different duct sizes? Just let us know. This section is for our high velocity equipment, but we have a complete line of Arzel damper sizes available, as well as accessories. For more information, email us, or call sales at (813) 977-5286.
