MAKING MODERN LIVING POSSIBLE Termix VX-C Compact 28 Indirect substation for apartments District cooling substation for indirect cooling. Designed for wall-mounting. Application District cooling (DC) District cooling is centralised production and distribution of cooling energy from the cooling plant to the air conditioning system of industrial, commercial or residential buildings. The Termix VX-C Comp. 28 offers a hydraulic break in the cooling system ahead of the air handling units (AHU) or fancoil units (FCU) in the apartments. The Termix VX-C Comp. 28 is a complete solution with optimal safety, efficient energy transfer, servicefriendly construction and a compact design. The Termix VX-C Comp. 28 substation is ideal, when a high level of security against burst pipes and water damage in the cooling system is required. The substation is prefabricated with a flow controller with integrated control valve, fitting piece and sensor pockets for insertion of an energy meter as well as strainers. •• Electronic regulation of cooling (CO) temperature Cooling (CO) •• Capacity: 14-26 kW cooling The apartment cooling circuit consists of a stainless steel plate heat exchanger, safety valve, pressure gauge, thermometers, drain valve, air valve, ball valves and circulation pump. The temperature of the cooling circuit is controlled by an electronic temperature controller. The electronic controller offers a very accurate setting of the flow temperature to the AHU or FCU. Construction All pipes are made of stainless steel. The connections are made by nuts and gaskets. Condensation insulation is not part of the delivery of the Termix VX-C Comp. 28 unit. districtenergy.danfoss.com FEATURES AND BENEFITS •• Minimum space required for installation •• Pipes and plate heat exchanger made of stainless steel •• Designed and optimised to fit the application •• Customised versions available Termix VX-C Compact 28 Circuit diagram – example DC Supply CO Supply DC Return CO Return A Heat exchanger F Electronic controller 1 Ball valve 4 Safety valve 9Strainer 10 Circulator pump 14 Sensor pocket, energy meter 18Thermometer Technical parameters: Nominal pressure: Max. supply temperature: DCW static pressure: Brazing material (HEX): Fluid medium: wall PN 16 Tmax = 50 °C Tmin = 0 °C Copper Water 19 Surface sensor 20 Filling / drain valve 24 Delivered loose with unit 25 Pressure gauge with ball valve 26 Pressure gauge 27Actuator 30 Flow control with control valve 41 Fitting piece, energy meter Connections: 1.
