Minimum water flow
In the following tables are indicated the minimum water flow allowed for each model. In case of variable
flow application where the speed of the pump is managed by an external BMS (trough 0- 10V signal) the
change in water flow rate must not be exceed more than 10% of the design water flow rate per minute.
The above values are referred to pure water (in case of glycol mixture contact factory).
Note: the performance are certified at standard conditions and with the unit operating with the
nominal water flow (corresponding to OAT 35°C; water in/out 12/7°C)

Water heat exchanger - maximum/maximum water Δt
The minimum
and maximum allowed ΔT at full load conditions are respectively 4 °C and 9°C. Contact
factory in case lower or higher ΔT are required.
