POMPE DE CALDURA, AER CONDITIONAT, CHILLER

Residential chillers and heat pumps

Climaveneta > Commercial and industrial heat pumps

FOCS-NR 1062 – 3222

Reversible unit, NRG line, total heat recovery, air source for outdoor installation Cooling capacity 199 – 826 kW

NECS 0202T - 0612T
Outdoor heat pump unit for the production of chilled/hot water with semi-hermetic screw compressors optimized for R134a, axial-flow fans, external coil with copper tubes and aluminium fines, shell and tubes heat exchangers designed by Climaveneta and thermostatic expansion valve. Base and supporting structure and panels are galvanized epoxy powder coated steel with increased thickness. These units are designed for two-pipes systems and are able to produce hot or cold water and even hot water on an auxiliary circuit when needed for domestic utilities or post heating for air conditioning units.

Version

  • CA – Class A of efficiency
  • LN-CA – Low Noise, Class A of efficiency
  • SL-CA – Super Low noise version, Class A of efficiency
  • XL-CA – eXtra Low noise version, Class A of efficiency
  • XL-CA-E – eXtra Low noise, Class A enhanced

Features

  • UNIQUE PROPOSAL
    Unique proposal: unit designed to satisfy, according to the mode of operation, requirements of cold water, hot water for heating or hot water for domestic use
  • WIDE OPERATING RANGE
    Unit´s operation guaranteed with external air temperature down to -10 °C during winter and up to 46 °C during summer.
  • HOT WATER SUPPLY
    Hot water supply up to 55 °C. In winter mode the unit manages hot water production in the plant-side heat exchanger and in the reclaim one, with priority setted by customer, eventually at two different set-points
  • CLASS A EFFICIENCY
    The full range is also available with the Class A efficiency rating (in heating).
  • VERSION ´XL-CA-E´ AVAILABLE
    Exclusive Premium version. Together for the first time, the lowest noise level on the market and the maximum efficiency in each operating mode.

Accessory

  • Compressor power factor correction
  • Hydronic group
  • VPF (Variable Primary Flow) kit: variable flow pumps with on board regulation
  • Set-up for remote connectivity with ModBus/Echelon protocol cards

Controls

  • W3000 large
    The W3000SE Large 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. The regulation operates on both water circuits featuring the step-wise regulation referred to the return water temperature with proportional logic. This allows to satisfy simultaneously the different requests of both cooling and heating, according to the selected operation mode. 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. Availability of an internal real time clock for operation scheduling (4-day profiles with 10 hour belts). 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.
