Air-Driven Zoning Technology: Why Arzel® Puts its Trust in Pneumatic HVAC Zoning

For homeowners and businesses alike, finding the most effective way to heat and cool their property is essential. That’s why Arzel® is trusting in pneumatic zoning—an air-driven zoning technology to control the temperature in different parts of the home or building. This blog post will explore why Arzel® is confident in this air-driven zoning technology.

Why Pneumatic Zoning Technology?

Some technicians will ask, “Why Pneumatic?” when zoning a central heating and cooling system. The image in their minds is commercial systems that use high-pressure airlines and air-driven thermostats, commonly found in hospitals. Some technicians think of these pneumatic systems as old-fashioned or “old school.” Others think they are a pain to service because of the large compressors that require specialty training.

However, Arzel® Zoning’s air-driven dampers are the core of our pneumatic zoning solutions. There’s no accurate comparison in answering the question of Arzel® low pneumatic vs. motorized vs. high-pressure pneumatics. It’s apples to oranges.

Flexible and Reliable

Arzel® dampers provide flexibility and reliability. Instead of complex gears, a bladder inflates and deflates based on vacuum or pressure. With fewer moving parts, there is less potential for failure, providing outstanding reliability.
Our small air cylinders fit places that mechanical gearing doesn’t. Our unique fit dampers, the EzyFit® and Inserta®, can be installed where traditional motor-driven actuators can’t. That makes Arzel® the best choice for retrofit zoning.

The ability to zone what was before impossible creates additional revenue streams and a competitive advantage. There’s also less mess in your customers’ homes because necessity of cutting drywall to install traditional zoning is reduced, often eliminated. Without expensive home remodeling, traditional zoning would be a tough sell. With Arzel, it is an easier proposal.

Installation Is Simple

The simplicity of our air-driven solutions means you won’t need specialty tools. Technicians can use common tools on their trucks today. Low pressure can easily be diagnosed with a digital manometer that reads at least 40″ w.c. +/-. The low-pressure airlines are a simple barbed compression fit that doesn’t require anything other than fingers (no glue or solvents, no thread sealant, nothing messy).

The simple airlines are faster, cheaper, and easier to install than the copper lines typical of the high-pressure pneumatic system. They have the same benefits compared to the low-voltage cabling of traditional zoning systems.

Up to Eight Zones

Flexibility also means more dampers with less hassle – Each stock Arzel® panel can support up to 35 actuators spread across two zones, three zones, etc. Arzel panels can support up to eight zones, but contractors should avoid micro or small zones.

24vac panels, on the other hand, require relay panels to support that number of dampers and beefy transformers.
Additionally, unlike traditional pneumatic systems, you won’t need a specialty thermostat. The standard 24-volt thermostats that technicians already stock on their trucks will do, so you won’t need additional truck stock.

Benefits of Pneumatic Zoning

Pneumatic zoning is one of the most reliable HVAC zoning technologies available, and it offers several benefits to anyone looking to optimize their heating and cooling system. To recap, pneumatic zoning, specifically the low-pressure pneumatics that Arzel® offers, provides the following benefits:

  • Easy Installation
  • Less Mess
  • Reliable Long-Life operation
  • Flexible Options with unique fit dampers such as the EzyFit® or Inserta®
  • More Dampers for Less
  • Common Tools of the Trade (Digital Manometer, Digital Volt Meter, Hand Tools)

Pneumatic zoning is not old-fashioned or complex. It is the solution to simple or complicated ducting, along with finished and unfinished basements. These benefits for contractors and homeowners are why we trust pneumatic technology.
