POMPE DE CALDURA, AER CONDITIONAT, CHILLER
NECS-WN 0152 – 1204
Reversible unit, water source
Coling capacity 43,4 – 371 kW
Water-cooled indoor unit for the production of chilled/hot water with hermetic rotary Scroll compressors, braze-welded plate-type exchanger and thermal expansion valve. External panels in pre-clad sheet steel (simil-Peraluman) and structure in galvanised steel with paint finish. The range includes the single-circuit two-compressor versions and the dual circuit four-compressor versions.
B – Basic
- REFRIGERANT GAS R410A
The use of R410A allowed to achive better energy efficiencies with environment full respect (ODP = 0)
- TOTAL VERSATILITY
Climaveneta has designed the NECS-W units with a range of integral accessories in mind for operation with total water loss (well, water bed, etc.), dry cooler or cooling tower so as to satisfy all service system and installation requirements.
- INTEGRATED HYDRONIC MODULE ON COOLER/CONDENSER SIDE
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 both on the evaporator and the condenser side.
- INTEGRATED CONDENSATION´S CONTROL
The electronics of the units manages the most suitable condensing control for each type of application: pressure-controlled valve, two or three-way modulating valve and inverter control for the pumps
- Set-up for remote connectivity with ModBus/Echelon protocol cards
- Condensing control device: two or three-way modulating pressure-controlled valve and inverter on pumps
- Water connections directed upwards (for 2 compressors units only)
- Acoustical enclosure to reduce the noise emissions.
- Rubber anti-vibration mounting kit. Spring anti-vibration mounting kit (4 compressors models only)
- W3000 Base – W3000SE Compact
The controller in two different versions according to the unit’s type: W3000 Base: electronic controller complete with keypad features an easy-to-use interface and a complete LCD display, allowing to consult and intervene on the unit by means of a menu up to three languages (Italian and English come standard, a further language can be chosen within French, Spanish, German, Russian and Swedish) W3000SE Compact: electronic controller complete with 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-language menu, with selectable language setting on site. This controller also includes an internal clock. All the W3000 electronic controllers offer 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. The regulation is 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 (available on W3000SE Compact only). 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. The internal real time clock allows to manage a weekly schedule operating on 4-day profiles with 10 hour belts (available on W3000SE Compact only, optional on W3000 Base controller). The defrost adopts a proprietary self-adaptive logic, which features the monitoring of numerous operational parameters. This allows to reduce the number and duration of the defrost cycles, with a benefit for the overall energy efficiency.
