Water-Cooled/Condenserless Liquid Chillers with Integrated Hydronic Module Air conditioning 30RW Options • High-pressure single or dual pump, evaporator • Condenser hydronic module with variable-speed single or dual pump • Heat pump (hot-water control) • Electronic starter for reduced startup current • RS485 communications and “CCN Clock Board” time schedule board • Very low temperature glycol solution down to -10°C • Field water connections at the unit top Features • Ten sizes with nominal cooling capacities from 109 to 315 kW. • Aquasnap chillers with scroll compressors, digital auto-adaptive Pro-Dialog control and ozone-friendly refrigerant HFC-407C. • Can be supplied with integrated hydronic evaporator and condenser modules, limiting the installation to simple operations such as the entering and leaving water piping connection. • Intelligent control of condenser water pump speed and operation of glycol cooler (30RW) or air-cooled condenser fans (30RWA) to ensure reliable and economical operation. • Quick electrical connections. • Units can operate down to -20°C outside temperature. • The variable-speed condenser water pump automatically adjusts the water flow rate to maintain the ideal condensing conditions. • High-performance plate heat exchangers maximise the thermodynamic properties of refrigerant HFC-407C. From size 30RW 160 the evaporator and the condenser have two interlaced refrigerant circuits. • Space-saving design. • No plant room required – unit can be installed in a place that is open to the public, if local regulations permit. • The refrigerant circuit is completely leak-proof. • Used with Carrier 09 series glycol coolers or air-cooled condensers, supplied ready for installation with a control box. All control components are installed and tested in the factory. Water cooled mono circuit A A Pro-Dialog Plus operator interface 56
