Water cooled heat pump reversible water side Cooling capacity 182 ÷ 2349 kW Heating capacity 205 ÷ 2610 kW • Production of hot water up to 55°C. • Production of chilled water down to -8°C. Units for internal installation offering chilled/hot water, designed to mit air conditioning needs in residential/commercial complexes or industrial applications. Compact and flexible, perfect alignment to the requested load thanks to an accurate control algorithm. The base, the structure and the panels are made of galvanized steel treated with polyester paint RAL 9003. ° Standard A High efficiency Operating field Production of chilled water up to 16 °C of water produced on the evaporator side, but also suitable for use in heat pump mode with condenser water temperature up to 55 °C. With option Z (double electronic expansion valve) the unit is capable to produce chilled water temperature from -8°C up to 10°C. Mono, bi-tri circuit unit Unit with 2-3 refrigerant circuits designed to provide maximum efficiency at full load, ensuring high efficiency at partial loads also and ensuring continuity in case one of the circuits stops. They are equipped with screw compressors and system and source side shell and tube heat exchangers with R134a refrigerant. The R513A (XP10) refrigerant with this type of gas is also available on the configurator. On average, the units have a yield > 2% and an EER < 3% compared to the same size with R134a. For further details refer to the technical documentation or to the Magellano selection program. The possibility to use electronic expansion valve, offers significant benefits, especially when the chiller is working with partial loads, increasing the energy efficiency of the unit. Standard for all sizes. WFN-HP-W_Y_UN50_04 Microprocessor adjustment, with keyboard and LCD display,for easy access on the unit is a menu available in several languages. Adjustment includes complete management of the alarms and their log. Possibility to control two units in a Master-Slave configuration The presence of a programmable timer allows functioning time periods and a possible second set-point to be set. The temperature control takes place with the integral proportional logic, based on the water output temperature. Electronic expansion valve CONTROL PCO₅ AER485P1: RS-485 interface for supervision systems with MODBUS protocol. AER485P1 x n° 2: RS-485 interface for supervision systems with MODBUS protocol. AER485P1 x n° 3: RS-485 interface for supervision systems with MODBUS protocol. AERBACP: Ethernet communication Interface for protocols Bacnet/IP, Modbus TCP/IP, SNMP AERNET: The device allows the control, the management and the remote monitoring of a Chiller with a PC, smartphone or tablet using Cloud connection. AERNET works as Master while every unit connected is configured as Slave (max. 6 unit); also, with a simple click is possible to save a log file with all the connected unit datas in the personal terminal for post analysis. MULTICHILLER_EVO: Control, switch-on and switch-off system of the single chillers where multiple units are installed in parallel, always ensuring constant flow rate to the evaporators. PGD1: Allows you to control the unit at a distance. AVX: Spring anti-vibration supports. FACTORY FITTED ACCESSORIES RIF: Power factor correction. Connected in parallel to the motor allowing about 10% reduction of input current.

ISG: Insulation kit for condensers. Mandatory accessory for machine functioning in heat pump; standard in units with desuperheater or with heat recovery.
