Heat Recovery Ventilator / Energy Recovery Ventilator Regional Application

Selecting The Right Unit

 

Each Fantech IAQ Product is designed using state-of-the-art technology and quality components
to give you long life and dependable operation. We guarantee it.

   

The climate conditions where you live will determine whether you need a Heat Recovery Ventilator or an Energy Recovery Ventilator.

HRV's are usually recommended for colder climates with longer heating seasons. ERV's are used for warmer more humid climates with long cooling seasons. Use map for reference.

*Note: When installing ERVs (in ERV areas according to the map), and the outdoor temperature falls below 23°F (-5°C) for more than 2 consecutive days, it is recommended that a defrost option be installed on the equipment.

 

Sizing For Your Residential Needs



HRVs/ERVs are typically sized to ventilate the whole house at a minimum of .35 air changes per hour. To calculate, simply take the square footage of the house (including basement) and multiply by the height of the ceiling to get cubic volume. Then, divide by 60 and multiply by .35.

*Note: Always consult your local code for sizing requirements in your area.

Inside the HRV/ERV Units



THE HEART OF THE SYSTEM

Fantech HRVs (like the unit shown above) feature polypropylene heat exchanger cores.

• In the heating season the core transfers heat from the outgoing, stale household air to preheat the incoming, fresh air.
•Cross-current sections, ensure the two air streams are always kept separate preventing the incoming fresh air from being contaminated by the outgoing stale air.
•During the air-conditioning season, the HRV reverses this process, removing some of the heat from the incoming air and transferring it to the outgoing air.

Fantech ERVs, which are ideal for warmer climates, use enthalpic cores to transfer both heat and moisture.
• Reduces indoor humidity in the air conditioning season.
• Maintains a comfortable humidity level in the home in the heating season.




ELECTRONIC CONTROL BOARD

Fantech Heat Recovery and Energy Recovery Units have been designed with new "high tech" electronic control boards. Features include:

• Accessory control contact allows the ventilator to connect to other equipment such as an existing forced air system to trigger the furnace blower motor to turn on and off on demand.
• A diagnostic LED
• Allows units to be easily operated from a remote Intellitek Multi-Function Wall Control.

CHOICE OF DEFROST MODE

The defrost mode activates when the temperature of incoming air is below 23°F (-5°C). Two types are available:

HRV without recirculation
• Features an automatic timed supply fan "shutdown".



continued

HRV with recirculation uses a motorized damper to temporarily block incoming fresh air allowing the warm air from the house to circulate through the HRV.
• Maintains equal house pressure.
• Does not introduce household odors back into the home.
• Provides positive shutoff of supply air when unit is in standby mode.

FACTORY-BALANCED EBM MOTORS

Fantech HRVs and ERVs use superior German-manufactured, factory-balanced EBM motors.

• Vibration is reduced to a minimum providing quiet operation.
• Permanently lubricated sealed bearings guarantee long life and maintenance-free operation.
• Typical life expectancy of motor is in excess of 100,000 hours.
• 7 year warranty (limited).
