When producing chilled water, these units can be connected to a
drycooler or a water cooling tower.
With the heat pump option, the units can produce hot water for
heating applications. They can also be used in cooling mode by
reversing the cycle on the hydraulic circuits using a set of valves
(hydraulic valves not supplied).
