CoolMizer: Energy Efficient Residential Economizer
More homeowners are looking for products, especially as a part of their HVAC system, to improve indoor air quality and reduce energy bills but maintain or even improve their comfort expectations. As an HVAC professional, you now have a product proven to provide healthier, more energy-efficient comfort with the award-winning Arzel Zoning CoolMizer system.

CoolMizer is the first all-in-one, Economizer/Fresh Air Intake system designed for residential and light commercial split systems. CoolMizer brings in fresh, outdoor air to not only provide ventilation benefits, but to also condition the air for “free” when conditions are right.
What is an Economizer?
The CoolMizer® economizer from Arzel is a device that selectively introduces outdoor air into any ducted heating and/or cooling system. It exchanges the air, moving warm, exhaust air from the inside and brings in cooler air from the outside, once outside conditions reach an accepted range for temperature and humidity.
It works by using the system’s blower, drawing air from outside the home or building through an opening controlled by dampers, which then is distributed through the duct system. It can perform this activity for heating or cooling purposes. When outside conditions are unfavorable, dampers close and regular action is resumed. Its mechanical action and reliance on outside air conditions help conserve action from a chiller or compressor. This activity helps lower energy consumption.
Benefits of CoolMizer
Homeowners can now minimize their energy usage as the CoolMizer reduces the compressor’s run time and utilizes the benefits of fresh outdoor air. And because of it’s visibility, CoolMizer is useable nationwide as different regions experience various comfort challenges. For example, in the north, homes may be warm during the spring and fall, but the air outside is temperate, while in the southwest, cool, dry nights supply plenty of air to provide free conditioning.
Increases indoor air quality & decreases energy usage
While the CoolMizer decreases energy usage, it increases indoor air quality by continually bringing in fresh air when pre-set conditions are met.

Since many homes are built or have been retrofitted to be “airtight,” homeowners may experience a decrease in their indoor air quality.
Improved ventilation and cleaner air
CoolMizer improves ventilation to provide cleaner, fresher air around the clock while it also dilutes and expels harmful VOCs, odors, and other contaminants. The CoolMizer can be integrated into bathroom and kitchen fans to better-rid homes of stagnant air and unpleasant odors. It also reduces carbon emissions by not burning any fossil fuels or using extra electricity to run.
CoolMizer delivers both ventilation and free conditioning by selectively introducing outdoor air with any ducted heating and cooling system. Utilizing the system’s blower, the air is drawn into the home through an opening controlled by Arzel retrofit-friendly dampers and distributed through the duct system.
This can be accomplished with two separate dampers, one large for free conditioning and one smaller for ventilation, or the patented Arzel Damper2 technology®. Damper2 technology is the only dual-purpose damper designed to provide both the benefits of free air conditioning and ventilation. This innovative damper is two dampers in one, each controlled individually as required.
Easy configuration and setup
The CoolMizer is ideal for retrofit or new construction forced-air applications, and configuration is simple with an easy-to-read LCD and set-up wizard. It can also be integrated with the Arzel Zoning system for more customized control of the airflow.
The Importance of Energy Savings
A more efficient HVAC system saves energy, translating into cost savings by significantly reducing the energy bills associated with heating or cooling a home or building. This is related to the fact that HVAC systems account for a significant portion of the energy usage in many homes. In addition, a more efficient HVAC system and energy reduction also reduce greenhouse gas emissions and other pollutants associated with energy production.
Finally, an energy-efficient HVAC system typically provides a longer lifespan than a less efficient system because it doesn’t cycle as often or work as hard. This reduces maintenance and stretches out the timeframe for potential system replacements.
