AIR-COOLED LIQUID CHILLERS WITH INTEGRATED HYDRONIC MODULE  30RB 008-015 Features and advantages ■■ Compressors -- Low-noise scroll or rotary compressors with low vibration levels -- The compressors are placed on anti-vibration mountings and maintenance-free. ■■ Air heat exchanger section -- The latest-generation low-noise fans are now even quieter and do not generate intrusive low-frequency noise -- Rigid fan installation for reduced start-up noise ■■ An HMI graphic service interface can be used to monitor and set the unit operating parameters. ■■ All units are equipped with 1 inch gas MPT water connections. ■■ Option for an integrated hydronic module reduces space requirements and simplifies the installation. Only the power and the water supply and the return piping need to be connected. COOLING Quiet operation Advanced technology and performance Economical operation ■■ Increased energy efficiency -- The high energy efficiency of the AquaSnap units is the result of a long qualification and optimisation process. -- AquaSnap units have Eurovent energy efficiency class A (size 008) or B (sizes 012 and 015) ■■ Reduced maintenance costs -- Maintenance-free scroll or rotary compressors -- Fast diagnosis of possible incidents and their history via the Pro-Dialog+ control -- R410A refrigerant is easier to use than other refrigerant blends Fast and simple installation and service ■■ Easy access to all internal components: simply undo three screws to remove the complete front panel to access the refrigerant piping connections, control box and electrical connections, as well as the compressor and other key parts. ■■ Advanced circuit design and component selection has resulted in a compact unit with an exceptionally small footprint that is easy to transport even through narrow doors. ■■ Reduced operating weight and a handle on the unit panels to facilitate transport. ■■ 3 bar pressure relief valve as standard ■■ Internal expansion tank ■■ High-pressure refrigerant protection ■■ Water flow switch to ensure that the circuits operate with the correct water flow rate. ■■ Various power cable outlet options: pre-punched holes in the cabinet panels permit cable exit on the side, front or rear. C A R R I E R 2 0 1 6 / 2 0 1 7 Environmental care ■■ Non-ozone depleting R410A refrigerant -- Chlorine-free refrigerant of the HFC group with zero ozone depletion potential -- Very efficient - gives an increased energy efficiency ratio (EER) ■■ Leak-tight refrigerant circuit -- Brazed refrigerant connections for increased leaktightness -- Verification of pressure transducers and temperature sensors without transferring refrigerant charge ■■ The components of AquaSnap systems are free of any hazardous substances. ■■ The new packaging ensures high protection during transport and handling and is 100% recyclable. 43 AIR TREATMENT ■■ Specially shaped anchorage feet ensure correct and safe unit fixing to the foundation. CONTROLS Patented fan blade shape and grille profile with low pressure drop HEATING HEATING ■■ The air management system, consisting of the propeller fan, orifice and air discharge grille, guarantees minimised sound levels. ■■ Wide temperature operating range: AquaSnap units can operate efficiently in extreme temperature conditions. To suit the requirements of all applications, the new AquaSnap units can work at low-ambient conditions in cooling mode (down to -10°C and up to 46°C outside temperature).
