Notes:
1. ECMs (Electrically Commutated Motors) are ideal for systems seeking maximum motor efficiency.
2. When attenuator is required, add inlet attenuator pressure to discharge static pressure for final fan performance.

Water Coil Performance Notes (I-P)
1.
Fouling Factor = 0.0005.
2. The off-coil temperature of the hot water coil on parallel fan-powered units must not exceed
140°F when mounted on plenum inlet.
3. The following equations may be used in calculating Leaving AirTemperature (LAT) and Water
Temperature Difference (WTD).

4. Capacity based on 70°F entering air temperature and 180°F entering water temperature. Refer to correction factors for different entering conditions.
5. For premium coils (.020” wall), water side pressure drop increases 17% and water velocity increases 7% for fixed GPM.

Water Coil Performance Notes (SI)
1.
Fouling Factor = 0.0005.
2. The off-coil temperature of the hot water coil on parallel fan-powered units must not exceed
60°C when mounted on plenum inlet.
3. The following equations may be used in calculating Leaving AirTemperature (LAT) and Water
Temperature Difference (WTD).
LAT
=
EAT
+ -----------------------------
WTD=EWT-LWT=kW/(4.19) L/s
4. Capacity based on 21°C entering air temperature and 82°C entering water temperature. Refer to correction factors for different entering conditions.
5. For premium coils (.020” wall), water side pressure drop increases 17% and water velocity increases 7% for fixed GPM.

Water Coil Notes (SI)
1.
Fouling Factor = 0.0005.
2. The off-coil temperature of the hot water coil on parallel fan-powered units must not exceed
60°C when mounted on plenum inlet.
3. The following equations may be used in calculating Leaving AirTemperature (LAT) and Water
Temperature Difference (WTD).
