Multi-purpose outdoor unit for use in 4-pipe systems for the simultaneous production of chilled and hot water by means of two independent hydronic circuits. These units are able to satisfy the demand for hot and cold water simultaneously through a system that does not require seasonal switching and is therefore a valid alternative to traditional plants with chiller and boiler. This unit is equipped with hermetic rotary Scroll compressors, with R410A, axial fans, shell and tube heat exchangers and electronic expansion valve. The range is composed by units equipped with four, six and eight compressors in multi-circuit configuration.
- B – Basic
- CA – Class A of efficiency
- SL-CA – Super Low noise version, Class A of efficiency
- REFRIGERANT GAS R410A
The use of R410A allowed to achive better energy efficiencies with environment full respect (ODP = 0)
- UNIQUE PROPOSAL
Unit designed to satisfy the cold and the hot side requirements simultaneously, for 4-pipe systems without any particular operation mode setting
- ENERGY SAVING
Energy saving guaranteed by the advanced operation’s logic. The best operation mode is set completely automatically and independently by the unit’s controller, in order to minimize the absorbed energy whatever the cooling and/or heating demand might be
- CLASS A EFFICIENCY
The full range is also available with the Class A efficiency rating (in heating). CA and SL-CA versions guarantee premium levels of efficiency thanks to the generous sizing of the refrigerant-exchange surface areas and to an accurate control of the fans, available on both standard and low-noise versions.
- INTEGRATED HYDRONIC GROUP
The built-in hydronic module already contains the main water circuit components; it is available with single or twin in-line pump, for achieving low or high head, available for both hot and cold water distribution systems (up to 4 pumps).
- Remote control keyboard (distance to 200m and to 500m)
- Soft starters
- Set-up for remote connectivity with ModBus, Echelon LonTalk, Bacnet protocol board
- LT kit for extending the operating limits in heat pump mode down to -10 °C (/SL-CA versions) and -12 °C (/CA versions)
