Hitecsa EQPL-B 4360 Manual Del Operador página 51

If the water inlet temperature to the condensers is lower than the permitted values, it is recommended to use a three-way modulating valve to guarantee
the minimum water temperature required.
Permitted temperature differentials through the heat exchangers
○ Evaporator temperature differentialAT = 3 ÷ 8°C with "Standard" set-ups. However, consider the minimum and maximum flow rates reported in the
tables "Water flow rate limits". The maximum and minimum temperature differentials for "Pump" and "Tank&Pump" set-ups are related to the
performance of the pumps, which must always be checked by means of the Up to Date selection software.
