MECH-iS-G07 0051 - 0112

Chiller, air source for outdoor installation 50,1 - 110 kW

Outdoor unit for the production of chilled water with variable speed Scroll compressors, optimized for R32 in a single-circuit configuration, micro-channel full-aluminum condenser coils, braze welded plate heat exchanger, axial-flow variable speed fans (inverter driven) with BLDC motor and electronic expansion valve as standard. Flexible and reliable unit; it easily adapts to different thermal load conditions thanks to the precise temperature control together with the use of inverter technology. The high performance levels, both at full and partial loads, is achieved thanks to the unit's accurate design and to the use of a fixed speed motor together with a variable speed (inverter) motor. Thanks to the high-end proprietary technology and to the accurate design, the units shows very high efficiency values, expecially at partial loads.

Features

LOW GWP REFRIGERANT

The pure refrigerant R32 is an extraordinary eco-sustainable alternative to traditional refrigerant R410A, offering a 66% reduction in terms of GWP, a higher efficiency and a lower refrigerant charge.

HIGH EFFICIENCY AT PARTIAL LOAD

Top-level partial load efficiency thanks to proprietary technological solutions at the forefront: VSD scroll compressors, EC fans as standard and advanced control algorithms.

EXTREMELY SILENT OPERATION

The best compromise between silence and efficiency, as result of a systematic design oriented to minimize noise levels.

EXTREME COMPACTNESS

The precise design and the meticulous attention to the details of each single component make this range the best-in-class solution in terms of footprint per kW.

WIDE OPERATING RANGE

Unit operation with outdoor air temperature from -20°C up to 50°C. Production of evaporator leaving water temperature from -12°C to 24°C to suit every application.

ALUMINIUM MICRO-CHANNEL HEAT EXCHANGERS

The full aluminium micro-channel condenser coils deliver high efficiency while ensuring a reduced refrigerant volume and a lower unit weight. The e-coating protection (optional) grants the highest level of corrosion resistance in any condition, even in the most aggressive environments.

PLUG&PLAY SOLUTION

The built-in hydronic module already contains the main water circuit components; it is available as option with single or twin in-line pump, low or high head, fixed or variable speed, expantion vessel and buffer tank.

GROUP CONTROLS WITH DYNAMIC MASTER

Load sharing, sequencing, active redundancy, priority of resource activation, alarm management, theese are only some of the LAN functions that the unit is able to manage when connected to a group of chillers. Besides, the system's stability is ensured even in case of alarm or malfunctioning thanks to the Dynamic Master logic.

VARIABLE PRIMARY FLOW

Energy savings due to variable pump speed management based on load demand and the variable flow ensures the units also function in critical working conditions.

Electronic control W3000+

W3000+ features an easy-to-use interface and a complete LCD display that allows one to consult and intervene by means of a multi-language menu (19 languages are available). The diagnostics includes a complete alarm management, with the “black-box” and the alarm history display for enhanced analysis of the unit operation. The programmable timer manages a weekly schedule organized into time bands to optimize unit performance by minimizing power consumption during periods of inactivity. Up to 10 daily time bands can be associated with different operating set points. As option, KIPlink is available - Keyboard In Your Pocket. KIPlink is the innovative user interface based on WiFi technology that allows one to operate on the unit directly from the smartphone or tablet. The regulation is based on the patented “Quickmind” water temperature regulation logic uses self-adapting control to maintain flow temperatures and optimize performance even in low water content scenarios. As an alternative, the proportional or proportional-integral regulations are also available. Optional proprietary devices can perform the adjustment of resources in systems made of several units. Consumption metering and performance measurement are possible as well. 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-over-IP, Bacnet MS/TP RS485, Konnex, ModBus TCP/IP, SNMP. Compatibility with the remote keyboard (up to 8 units).
