Image RC IT REFROIDISSEMENT GROUPE FROID CONDENSATION A AIR NRCS-Z 1314 – 3218

NRCS-Z 1314 - 3218
Chiller, air source for outdoor installation
334 - 885 kW

Description
Outdoor unit for the production of chilled water with hermetic rotary Scroll compressors, ozone-friendly refrigerant R410A, axial-flow fans, shell and tubes exchanger and electronic expansion valve. The range is composed by units equipped with four, six and eight compressors in multi-circuit configuration.
Versions
- B - Basic
- SL - Super-low noise version
- CA - High efficiency version
- SL-CA - Super-low noise, high efficiency version
Configurations
- - - Basic function
- D - Partial condensing heat recovery function
- R - Total condensing heat recovery function
Features
- REFRIGERANT GAS R410A
  The use of R410A allowed to achive better energy efficiencies with environment full respect (ODP = 0)
- ALUMINIUM MICRO-CHANNEL HEAT EXCHANGERS
  This new range of chiller uses aluminum micro-channel condensers that ensure a premium level of efficiency. This solution also allows to reduce the refrigerant charge with respect to traditional copper/aluminum coils, assuring the minimum allowable ratio between the refrigerant volume and the power capacity thus making this product range unique in the market, also improving the resistance against corrosion in saline or corrosive atmospheres.
- 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.
- ELECTRONIC EXPANSION VALVE SUPPLIED STANDARD
  The use of the electronic expansion valve generates considerable benefits, especially in cases of different external conditions. It was introduced into these units as a result of accurate design choices concerning the cooling circuit and the optimisation of operation in various different working conditions
- INTEGRATED HYDRONIC GROUP
  The optional built-in hydronic module already contains the main water circuit components; it is available with single or twin in-line, for achieving both low or high head.
Accessories
- Set-up for remote connectivity with ModBus/Echelon protocol cards
- Remote control keyboard (distance to 200m and to 500m)
- Soft starters
Contrôles
Control
- W3000SE Compact
  W3000SE Compact controller offers advanced functions and algorithms. The keypad features an easy-to-use interface and a complete LCD display, allowing to consult and intervene on the unit by means of a multi-level menu, with selectable language setting.Regulation based on the exclusive QuickMind algorithm, including self-adaptive control logics, beneficial in low water content systems. As alternatives the proportional- or proportional-integral regulations are also available. The diagnostics includes a complete alarm management, with the "black-box" and alarm logging functions for enhanced analysis of the unit operation.For multiple units’ systems, the regulation of the resources, via optional proprietary devices, can be implemented. Energy metering, for both consumption and capacity, can also be developed. 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, Bacnet-over-IP, Echelon LonWorks.- Compatibility with the remote keyboard managing up to 10 units.
