NRCS-Z 0202T - 0612T
Chiller, air source for outdoor installation
50,7 - 159 kW
-
format_align_leftDescriptionOutdoor unit for the production of chilled water with hermetic rotary Scroll compressors, axialflow fans, shell and tubes exchanger and thermostatic expansion valve. External panels in Peraluman and structure in aluminium sections. The range is equipped with two compressors on two independent refrigerant circuits.
Versions
- B - Basic
- LN - Low noise
- SL - Super-low noise version
- HT - High efficiency, high outdoor temperature version
Configurations
- - - Basic function
Features
- EXCHANGER
The shell and tube exchanger allows to achieve the highest flexibility on the unit’s installation, keeping on the hydronic side the pressure drops at the minimum level, thus representing the best choice for all the hydronic applications on the IT Cooling market. - MAXIMUM RELIABILITY
Unit with two independent refrigerant circuit, designed to ensure maximum efficiency at full load, ensuring uninterrupted operation even in the event of temporary stop of one of the two circuits. - INTEGRATED HYDRONIC GROUP
The built-in hydronic module includes the main water circuit components; it is available in various configurations with one or two pumps with high or low head.
Accessories
- Traditional coils available with prepainted fins or Fin Guard Silver protective treatment.
- Copper-Copper heat exchanger coils
- Compressor power factor correction
- Soft start
- Compressor suction and discharge valves
- High and low pressure gauges
- Compact keyboard with LCD display and multi-language user interface (referred to the shown picture)
- Hydronic group
- B - Basic

Control
- Electronic control W3000
The W3000 controller offers advanced functions and algorithms. The Base keyboard features an easy-to-use interface that allows consulting and intervening on the unit by means of a multi-level menu. The Compact keyboard (optional) has a complete LCD display with an interface available in three languages: Italian, English and a further language among French, Spanish, German, Russian and Swedish. The alarm history display function can be enable by installing a real-time clock (optional) (only with Compact keyboard). The regulation is based on the patented “Quickmind” water temperature regulation logic uses self-adapting control to maintain flow temperatures and optimise performance even in low water content scenarios. As an alternative, the proportional or proportional-integral regulations are also available. Optional proprietary devices can perform the adjustment of the resources in systems made of several units. Consumption metering and performance measurement are possible as well. Supervision can be easily developed via proprietary devices or the integration in third party systems by means of the most common protocols as ModBus, Bacnet, LonWorks. Compatibility with the remote keyboard (up to 8 units) (only with Compact keyboard). The defrosting (air source reversible unit only) follows a proprietary self-adaptive logic, which features the monitoring of several operational parameters. This allows to reduce the number and duration of the defrost cycles, with a benefit for the overall energy efficiency.
