NEPTUNE

Water-cooled chillers, heat pumps and condenserless units with R407C equipped scroll compressors. Cooling capacities 286 - 706 kW.

Neptune’s water-cooled configuration with up to 3 scroll compressors IN PARALLEL offers high energy efficiencies in the partial load conditions which are typical in industry. The extremely compact open- frame design maximizes installation.

HIGH ENERGY EFFICIENCY SMART CONTROLS

Neptune units are designed to offer optimal energy efficiency and consequently maximum operating economy. Thanks to the use of tandem or trio scroll compressors installed in one or two independent circuits, mated with an oversized evaporator section, Neptune can achieve ESSER values of up to 5.9, meaning that on average 1 kWh of electrical power is required to remove 5,9 kWh of heat energy from the process fluid. The microprocessor has an icon-based display offering a clear presentation of the values for all main functional parameters. The microprocessor itself exchanges data with peripheral systems at several levels, from dialogue with users to dialogue with the supervision network, also by means of an optional GSM modem, or towards the most widely used Building Management Systems (BMS). The optional XWEB 300 device is a small supervisor system which supports connectivity with PCs or PDAs equipped with a browser. This device allows the display and editing of the functional parameters, plus alarms visualization and resetting.

MULTISCROLL COMPRESSORS

Scroll compressors installed in tandem or trio configurations ensure high performance and elevated energy savings at partial loads. Thanks to the reduced number of moving parts and the absence of suction and discharge valves, scroll compressors feature reduced maintenance requirements and a minimal emission of noise and vibration, whilst guaranteeing absolutely reliable operation.

VERSIONS

• • Standard; Low noise; •• ME - Condenserless unit combinable with remote condenser; Heat pump with inversion on the water side.

COMPLETE MODULARITY

Neptune can meet the needs of a wide range of industrial applications, thanks to its many different configurations and generous operating limits. Neptune can be supplied in cooling only, heat pump, condenserless and low noise versions, with total or partial recovery exchangers.

SIMPLE INSTALLATION AND MAINTENANCE

The extremely compact footprint and limited width allow easy installation in cramped plant rooms and transit through standard size doors, thus reducing installation times and costs. In addition, class leading sound emission performances dispense with the need to install costly sound insulation. Troublefree and unimpeded access to the main components of the refrigerant circuit, plus the microprocessor’s simple and intuitive graphic interface, combine to simplify maintenance activities, minimising downtimes and maintenance costs.
