Unico vs. Conventional Ducted Systems

•
Roughly half the CFM (200-250 vs. 400)
High Static Pressure (Avg. 1.5” w.c.)
Refrigeration Coil vs. A/C Coil
Greater Temp. Drop in AC
1000 to 2000 fpm velocity
Aspiration vs. Diffusion and Throw and
Return
THREE BIG DIFFERENCES
• 1. Airflow
• 2. Aspiration
• 3. Static Regain
Unico vs. Conventional

•
•
Roughly half the CFM (200-250 vs. 400)
Refrigeration Coil vs. A/C Coil
Greater Temp. Drop in AC
Warmer Temperatures in Heat Pump
Lower Airflow & 6 Row Coil
Removes 30% More Moisture
Higher Discharge Temperature
No Need for Electric Heat to Feel Warm
122°F (50°C)
Discharge Air Temp
At 47° Rating Point
Eliminates Cold Blow Complaints
Unico vs. Conventional
• High Static Pressure (1.5” w.c.)*
• High Velocity (1000-2000 fpm)
• *NOT consider high static pressure by
