VentZone 2 Bathroom Ventilation Package with 150 CFM HRV (Heat Recovery Ventilator) (39 300).  Provides continuous and boosted zoned ventilation to 2 bathrooms + fresh air to your home.

This Kit Includes:
(1) Aldes model LT-15 Heat Recovery Ventilator - 150 CFM with 6" Ports and Damper Defrost System - Ventilates homes up to 2,800 square feet
(1) 6" VentZone Register Terminal  (ZRT) - includes motorized damper with integral Minimum Airflow Regulator (perfect for master bathroom)
(1) 4" VentZone Register Terminal (ZRT) - includes motorized damper with integral Minimum Airflow Regulator (perfect for smaller bath / powder room)

American Aldes has developed new technology that makes it possible to turn a whole house IAQ system into a highly effective central bathroom ventilation system and vice versa.

This VentZone IAQ System utilizes a whole house Heat Recovery System combined with Zone Register Terminals to remove stale and humid air from the bathrooms at a low volume continuous rate and provides a high volume boosted rate when the bathrooms are occupied. By doing this homeowners are able to recover the energy (heating or cooling) from stale air drawn from the bathrooms to condition fresh air being brought into the home. This technology makes far more sense than sending conditioned air from common areas into an HRV or ERV and having multiple noisy bathroom fans all blowing tempered air out of multiple penetrations through the roof.

This is accomplished by installing automatic self-balancing Constant Airflow Regulators through motorized damper doors in Zone Register Terminals in the ceiling of each bathroom of the home. Each ZRT also contains a micro-switch that tells the Energy Recovery System to boost airflow when the motorized damper opens during the times the bathrooms are in use. By utilizing regulated and balanced airflow controls, homeowners benefit from maximum energy savings, comfort and IAQ improvement.

Even though this technology delivers far greater performance and IAQ benefit than standalone bath fans and an HRV unit bolted onto a furnace, the cost for a complete system with heat recovery retails for very affordable price.

With the new Energy Efficiency standards and codes being introduced (such as ASHRAE 62.2 and California's Title 24) builders are able to utilize the VentZone IAQ system to meet code requirements, improve performance and save costs by installing one simple system.

How does it work?

Each VentZone terminal contains a primary flow damper that opens when called upon by a switch, timer, dehumidistat, or occupancy sensor.  Once the damper is opened - the VentZone terminal signals the HRV to operate on high speed and only boosts flow from the open VentZone terminal.    This provides the distinct advantage of allowing the fan to only ventilate specific spaces when called upon, again without the need for separate fans in each space. This is especially important in residential bath exhaust applications using popular in-line and multi-port fans, where extremely low noise and single exterior vent penetrations are desired. 

With this kit - the fan in the HRV will run continuously - offering 10, 20, or 30 CFM of constant ventilation in each bathroom - plus fresh air supply to different areas of your home.   When local switch is activated - the primary control damper will open - boosting the ventilation to a high level (amount of airflow can be regulated precisely via an optional Constant Airflow Regulator inserted into the "neck" of the register terminal).
