WATER-COOLED LIQUID CHILLERS  30XW 254-1762 No. Description Advantages Use 30XW Medium-temperature brine solution 5 Implementation of new algorithms of control and evaporator redesign to allow chilled brine solution production down to -6°C when ethylene glycol is used (-3°C with propylene glycol) Covers specific applications such as ice storage and industrial processes Only sizes 512/562/ 1012/1154 Low-temperature brine solution 6 Implementation of new algorithms of control and evaporator redesign to allow chilled brine solution production down to -12°C when ethylene glycol is used (-8°C with propylene glycol) Covers specifi c applications such as ice storage and industrial processes Only sizes 512/562/ 1012/1154 Light-brine solution, down to -3°C 8 Implementation of new algorithms of control to allow chilled brine solution production down to -3°C when ethylene glycol is used (0°C with propylene glycol) Matches with most application requirements for ground-sourced heat pumps and fits with many industrial processes requirements 254-1762 Unit supplied in two assembled parts 51 The unit is equipped with flanges that allow disassembly of the unit on site Facilitates installation in plant rooms with limited Only sizes access 1612/1652/ 1702/1762 Master/slave operation 58 Unit equipped with supplementary water outlet temperature sensor kit to be field-installed allowing master/slave operation of two units connected in parallel Optimised operation of two chillers connected in parallel with operating time equalisation 254-1762 Single power connection point 81 Unit power connection via one main supply connection Quick and easy installation 1002-1762 No disconnect switch, but short circuit protection 82A Unit without disconnect switch, but with shortcircuit protection device Permits an external electrical disconnect system for the unit (field-supplied), while ensuring unit short circuit protection 254-1762 Evaporator pump electrical power / control circuit 84 Unit equipped with an electrical power and control circuit for one pump evaporator side Quick and easy installation: the control of fixed speed pumps is embedded in the unit control 252-1252, 1314 Evaporator dual pumps electrical power / control circuit 84D Unit equipped with an electrical power and control circuit for two pumps evaporator side Quick and easy installation: the control of fixed speed pumps is embedded in the unit control 252-1252, 1314 Condenser pump electrical power / control circuit 84R Unit equipped with an electrical power and control circuit for one pump condenser side Quick and easy installation: the control of fixed speed pumps is embedded in the unit control 252-1252, 1314 Condenser insulation 86 Thermal condenser insulation Minimizes thermal dispersions condenser side (key option for heat pump or heat recovery applications) and allows compliancy with special installation criteria (hot parts insulated) 254-1762 Service valve set 92 Liquid line valve (evaporator inlet) and compressor suction line valve Allow isolation of various refrigerant circuit components for simplified service and maintenance 254-1762 Evaporator with one pass 100C Evaporator with one pass on the water side. Evaporator inlet and outlet on opposite sides. Easy to install, depending on site. Reduced pressure drops 254-1762 Condenser with one pass 102C Condenser with one pass on the water side. Condenser inlet and outlet on opposite sides. Easy to install, depending on site. Reduced pressure drops 254-1762 21 bar evaporator 104 Reinforced evaporator for extension of the maximum water-side service pressure to 21 bar (standard 10 bar) Covers applications with a high water column evaporator side (typically high buildings) 254-1762 21 bar condenser 104A Reinforced condenser for extension of the maximum water-side service pressure to 21 bar (standard 10 bar) Covers applications with a high water column condenser side (typically high buildings) 254-1762 Reversed evaporator water connections 107 Evaporator with reversed water inlet/outlet Easy installation on sites with specific requirements 254-1762 Reversed condenser water connections 107A Condenser with reversed water inlet/outlet Easy installation on sites with specific requirements 254-1762 JBus gateway 148B Two-directional communication board complying with JBus protocol Connects the unit by communication bus to a building management system 254-1762 LON gateway 148D Two-directional communication board complying with Lon Talk protocol Connects the unit by communication bus to a building management system 254-1762 Bacnet over IP gateway 149 Two-directional high-speed communication using BACnet protocol over Ethernet network (IP) Easy and high-speed connection by ethernet line to a building management system. Allows access to multiple unit parameters 254-1762 High condensing temperature 150 Optimized compressor for operation at high condensing temperature Increased condenser leaving water temperature up to 63°C. Allows applications with high condensing temperature (heat pumps, installations with not generously sized drycoolers or more generally, installations with drycoolers in hot climate). NOTE: to ensure control of the condenser leaving water temperature, this option must be fitted with 30XWH units. 254-1762 Condensing temperature limitation 150B Limitation of the maximum condenser leaving water Reduced maximum power input and current temperature to 45°C absorption: power cables and protection elements can therefore be downsized C A R R I E R 2 0 1 6 / 2 0 1 7 CONTROLS AIR TREATMENT HEATING HEATING Options COOLING Options 254-1762 253
