Features
REFRIGERANT GAS R410A
The use of R410A achieves better energy efficiencies while respecting the environment (ODP = 0)
SHELL&TUBE HEAT 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. For this reason, NECS-N-Y represents the best choice for all the hydronic applications on the process market.
ELECTRONIC EXPANSION VALVE SUPPLIED AS STANDARD
The use of the electronic expansion valve generates considerable benefits, especially in cases of variable demand and 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; available with single or twin in-line, for achieving both low or high head.

W3000SE Compact
W3000SE Compact offers advanced functions and algorithms.
The keypad features an easy-to-use interface and a LCD display, allowing you 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 unit operation.
For multiple unit 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.
- Internal real time clock available 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 reduces the number and duration of the defrost cycles, with a benefit for the overall energy efficiency.
