    FIELDS OF THE RANGE Water-water offering chilled/hot water, designed to mit air conditioning needs in PLUG AND PLAY residential/commercial complexes or industrial applications. Indoor units with hermetic scroll compressors and plate heat exchangers. All the units are equipped with scroll compressors and plate heat exchangers; the In the configuration with desuperheater, it is also possible to produce free-hot wa- base and panelling are made of steel treated with RAL 9003 polyester paints.
  • Page 7: Unit Components Description

    UNIT COMPONENTS DESCRIPTION High pressure transducer REFRIGERANT CIRCUIT Placed on the high pressure side of the cooling circuit, signals the work pressure to control board, generating a pre-warning in case abnormal pressure occurs. Compressors Low pressure transducer High-efficiency scroll hermetic compressors with 2-pole electric motors. All the compressors are equipped with inner electronic thermal protection device.

  • Page 17: Pumps Static Pressure

    PUMPS STATIC PRESSURE The table shows the characteristic curves of the pumps, and therefore they do not represent the useful static pressures of the system. The useful heads of the system must be calculated by subtracting the unit's pressure drops (Δp) from the useful head of the pump shown in this diagram (see chapter:  Pressure drops p. 15).

  • Page 19: Expansion Vessel Setting

    EXPANSION VESSEL SETTING The expansion tank volume is 6.3 gal. The standard value of the expansion tank pre-charge pressure is 21.8 psi, but this can be calibrated up to a maximum of 87.0 psi. The expansion tank pressure setting has to be adjusted based on the difference in height (H) of the installation (see figure) according to the formula: p (rating) [bar] = H [ft] / 33.5 + 1.0.
