Pump units distribution systems for thermal power plant USE The PUMP UNITS optimize space and functionality in the heat station: their strengths are modularity, flexibility, the possibility of customization and an extremely compact and tidy design. They are available in three versions: • direct zone: high temperature • mixing fixed-point zone: with thermostatic valve adjustable between 30°C and 60°C • mixing modulating zone: with control unit and climatic regulation The PUMP UNITS are completed with manifold, separator and insulation to form a COMPARATO SYSTEM for thermal power stations. KEY FEATURES • Easy installation • Compact size • Adaptability to different types of plant • Full insulation • Design 9 Hot sanitary water recirculation Cold sanitary water Diacom MINI compensator Control unit External probe for climatic function DIRECT pump unit Room thermostat MIXING MODULATING pump unit MIXING FIXED-POINT pump unit

Pump units DIRECT PUMP UNITS The DIRECT pump units are able to provide the right flow rate and proper head to the heat transfer fluid in hydraulic circuits where the control of the delivery temperature is not necessary. Complete with high-efficiency pump, flow and return thermometers, system-side interception valves, non-return valve, shell insulation. The unit is reversible, in fact it is possible to reverse the flow from right to left, depending on the installation requirements.
