CFM Continental Fan ECO-FLO PLUS Energy Recovery Ventilator (ERV).
Product Overview:
Continental Fan’s ECO-FLO PLUS Energy Recovery Ventilator (ERV) is the all-in-one ventilation solution for new construction and renovation projects. This compact unit is capable of exhausting stale indoor air and supplying fresh filtered air from outside. The ERV core extracts thermal energy from the exhausted air and uses it to either pre-heat or pre-cool the incoming supply air (depending on the season).
ECO-FLO PLUS operates in the heat recovery mode with two cycles. Two units intake/exhaust air alternately at the same time to achieve balanced ventilation. It will increase the indoor comfort and make ventilation more effective. The heat and humidity in the room can be recovered during ventilating and the load on cooling system can be reduced in summer.
Features & Benefits:
- Clean, simple front panel
- Automatic shutter to prevent back drafts

ERV vs. HRV: What's The Difference:
An HRV is designed to supply fresh air to a home, and exhaust stale air from the home. The core of an HRV stores heat from the stale exhaust air in winter, and pre-heats the incoming supply air. In the summer, the core is effectively chilled by the exhausted air, and it pre-cools the incoming supply air.
- Suitable in colder climates where there is excess humidity during the heating season.
An ERV does everything that an HRV does. In addition, an ERV allows some of the moisture in the more humid air stream to be transferred to the air stream that is dryer. This limits the amount of moisture that is expelled in the winter and that enters during the summer.
- Suitable for colder climates with no excess humidity during the heating season, as well as for warmer climates with high outdoor humidity in the cooling season.

Selection:
The criteria to be considered when designing a ventilation network are regional climate and square footage of the building. The climate is the deciding factor whether an ERV or an HRV will be more effective, while the square footage determines how many ventilators will be required.

Operating Modes of an Energy Recovery Ventilator:
Natural Airflow
• Shutter is open; fan does not run.
• Air flows freely through the ventilator and is purified by filters.
Supply Mode
• Ventilator continuously draws in fresh air from outside.
• Air is purified by the filters.
Ventilation Mode
• Ventilator operates in permanent supply or extract mode.
• Synchronized units can provide balanced ventilation.
Regeneration Mode
• Ventilator alternates between supply and exhaust operation every 70 seconds.
• Thermal energy is recovered, and the humidity setting is maintained.
Cycle I
Warm stale air is extracted from the room. It heats and moisturizes the ERV core, transferring up to 90% of the thermal energy. In 70 seconds, the ventilator switches to supply mode.
Cycle II
Fresh outside air flows through the ventilator, absorbing the accumulated moisture and thermal energy in the ERV core and supplying warmed air into the room. In 70 seconds, the ventilator switches back to extraction mode.
