2 MINI CHILLER Highly efficient heat pump for summer and winter air conditioning. Ideal for residential and commercial applications of small size. AIR-TO-WATER HEAT PUMP Full DC Inverter Monobloc with built-in hydronic system Hokkaido MINI CHILLER allows to meet the different air-conditioning needs of environments by powering hydronic systems at medium and low temperature such as fan coil, highefficiency radiators or floor heating systems. Full DC Inverter technology and the high reliability of components make MINI CHILLER a system characterized by the highest efficiency and energy saving. REFRIGERANT GAS R410A All the models are ErP Ready and in A+ energy efficiency class in heating. Thanks to its high performance, MINI CHILLER is accessing state incentives with all its range [for Italian market only]. MINI CHILLER is composed of: 1-Phase models, available in 4 capacities of 5 kw, 7 kw, 10 kw and 12 kw; 3-Phase models, available in 3 capacities of 12 kw, 14 kw and 16 kw. ENERGY CLASS A+ (all models) COP 4.60 model 5 kw 1-Phase, 5~7 kw 1-Phase, 10~12 kw 3-Phase, 12~16 kw HCWNMS 501 X HCWNMS 1001 X HCWSMS 1201 X HCWNMS 701 X HCWNMS 1201 X HCWSMS 1401 X HCWSMS 1601 X

3 WHY CHOOSE MINI CHILLER: EFFICIENT Reduced consumptions and energy saving: thanks to the built-in Full DC Inverter technology, MINI CHILLER continuously modulates the output power in cooling and heating, in line with the actual needs; therefore, it only takes the energy needed, adjusting the input power to the load instantaneously. ULTRA COMPACT The monobloc unit has a very compact structure, thanks to the optimization of inner components, thus including the built-in hydronic system with the minimum space occupied. ECO-FRIENDLY MINI CHILLER uses R410A refrigerant at low environmental impact, which does not damage the ozone layer. MAXIMUM COMFORT The Inverter control allows to reach quickly the desired temperature when the units starts, with a remarkable reduction of time for regularly running. The indoor temperature is kept constant, avoiding annoying variation as regards the set temperature, in order to ensure the optimal comfort. PLUG & PLAY SOLUTION The installation is really easy thanks to the built-in hydronic module including the electronic water pump (standard supplied), the expansion vessel (up to a max. of 40 or 60 litres of water volume in the system, according to the capacity), the automatic vent valve and the safety devices. Only the connection of unit to the water and electrical system is needed. RELIABLE AND EFFICIENT TECHNOLOGY TWIN ROTARY DC INVERTER COMPRESSOR Highly efficient DC Inverter motor with double balanced eccentric cam. Extended frequency modulation field. The start/stop cycles are less frequent, thus increasing the useful life of the system. HIGHLY EFFICIENT HEAT EXCHANGER WATER SIDE Plate brazed, stainless steel AISI 316, with anticorrosion treatment. Better heat transmission. Built-in antifrost protection (standard supplied). FAN High-performance DC Inverter motor. Best comfort thanks to the absence of vibrations. Increased air flow treated thanks to the optimized profile of larger fans and new design of front grille. HEAT EXCHANGER AIR SIDE High heat exchange efficiency thanks to the new geometry of finned heat exchanger, improving the air passage through the rows. Copper pipes with high internal turbulence and aluminium fins with surface treatment, improving the resistance to corrosion and ensuring a long life. CONTROLS Intuitive management of unit by a control on unit itself, or by a remote control system with LCD touch display (optional accessory DHW CWM)*. Main functions of DHW CWM: selection and display of different parameters and operation modes; weekly timer; display of eventual error codes (selfdiagnosis). Possible use of a further remote controller by dry contacts for on/off functions and heat/cool reversal. * When the remote control system is connected, the control on unit is used only for functions of display, check and troubleshooting. ELECTRONIC EXPANSION VALVE Optimal control of refrigerant flow inside the circuit, with better performance and reduction of defrost cycles.
