temperature difference between entering and leaving water temperature.
Unit with electric heater (gI)
Flow rates over 4.2 l/(min.kW) will cause excessive erosion.
(1) Conditions: Water entering/leaving temperature: 7/12 °C, Air inlet temperature 27/19°C DB/WB - Nominal air flow
Flow rates below the minimum recommendation must be avoided to avoid laminer flow, potential exchanger
(2) Conditions: Water entering/leaving temperature: 50/45 °C, Air inlet temperature 20°C DB - Nominal air flow
freezing scaling and poor temperature control.
(3) At high speed with nominal air flow.
(4) Water entering/leaving temperature 90/70 °C, air inlet temperature 20 °C DB, Nominal air flow.
(5) A rectangular glass wool duct 1m50 long is placed on the blower.The measurement is taken in the room containing the blower unit.
Heat exchanger operating limits:
FWD:
*water temperature: max 100° C
*absolute service pressure: min 1 bar/max 11 bars
Accessories - Hot water coil:
*water temperature: min. +2° C/max. 100° C
*absolute service pressure: min 1 bar/max 11 bars
