1 Water cooled internal chiller and heat pump units with scroll compressors Cooling capacity from 106 kw to 385 kw NXW Heating capacity from 119 kw to 419 kw R410A Aermec participates in the EUROVENTProgram: LCP/W/P/C - LCP/W/P/R I prodotti interessati figurano sul sito HIGH EFFICIENCY VERSION CLASS "A" EUROVENT HEAT PUMP WITH REFRIGERANT SIDE REVERSING FOR GEOTHERMAL APPLICATIONS OPTION OF 1 OR 2 PUMPS ON BOTH EVAPORATOR AND CONDENSER SIDE PRODUCTION OF HOT WATER UP TO 55 C C Characteristics NXW is the range of water cooled heat pumps that operate with refrigerant R410A. They are internal units with hermetic scroll compressors that respond perfectly to the market requirements: small dimensions, ease of installation, low noise. Maximum energy efficiency For years Aermec has been attentive to the energy efficiency issue, and has now designed the NXW units with the aim of ensuring high efficiency levels with both full and partial loads. The results are an EER level of 5.05 and COP at 4.45 (Class A Eurovent) Models available NXW : water side reversible heat pump NXWH: refrigerant side reversible heat pump All models are available in low noise version Evaporator and/or condenser side pump unit The machine can be supplied with a hydronic Accessories AER485P1: RS-485 interface for supervision systems with MODBUS protocol. AERWEB300: Accessory AERWEB allows remote control of a chiller through a common PC and an ethernet connection over a common browser; 4 versions available: - AERWEB300-6: Web server to monitor and remote control max. 6 units in RS485 network; - AERWEB300-18: Web server to monitor and remote control max. 18 units in RS485 network; module for both the evaporator and the condenser side; each module includes a water filter fitted, low or high head pump, flow switch, and a 25 litre system side expansion tank, thereby optimising space, time and installation costs. It is possible to request a standby low or high head pump. Advanced controls The NXW controller provides several functions: - Two chiller units in parallel (run/standby) - Programmed pump rotation - Inverter condenser pump control to manage the condensing pressure - Programmable time-clock - Automatic water set point compensation - Data logging Construction details: Structure and base in hot dip galvanised sheet steel with epoxy pain finish (RAL 9002) - AERWEB300-6G: Web server to monitor and remote control max. 6 units in RS485 network with integrated GPRS modem; - AERWEB300-18G: Web server to monitor and remote control max. 18 units in RS485 network with integrated GPRS modem; PGD1: In addition to the unit mounted controller on the NXW unit a remote mounted PGD1 panel can be supplied providing the same functions (keyboard controls and display). RIF: Power factor correction. Connected in High efficiency plate heat exchangers Compressors with high performance and low electrical input High and low pressure transducers as standard Conforms with Safety Directives (CE) and the standards regarding electromagnetic compatibility The safety of the unit is provided by the door interlocked isolator and active protection of the main components Externally mounted user interface with display of all operating parameters in 4 languages User-friendly remote mounted control panel with alarm notification. parallel to the motor allowing about 10% reduction of input current. Must be requested at time of order and is available factory fitted only. AVX: spring anti-vibration mounts. DRE: oft starter (current reduction of about 30% for single circuit units, 26% for two circuit units, 22% for three circuit units). Only available for 400V-3-phase power supply. Factory fitted only.
