4 Acvatix for central HVAC plants The heart: the central HVAC plant Whether they operate with water, steam or heat transfer oils, central HVAC plants are used to generate and distribute heating and cooling energy to maintain comfortable temperatures in buildings, zones and rooms. They consist of primary plants for heating, cooling, ventilation and air conditioning as well as of distribution networks in buildings and district heating/cooling systems. Acvatix valves and actuators ensure energy-efficient operation for optimum comfort in all operating and load situations. Your variety for energy generation and distribution Acvatix offers you all types of valves and actuators required for central HVAC plants. The range includes 2-port and 3-port valves with flanged or threaded connections and butterfly valves combined with actuators that can be driven by all room and building automation controllers. The valves are suited for open and closed circuits with water, water with anti-freeze, drinking water, steam and other media. This means that with Acvatix, you can implement all control, shutoff and changeover functions in HVAC and drinking water plants, whether simple, small, large or complex. Everything for high energy efficiency Acvatix helps to ensure that buildings achieve the highest energy efficiency classes according to the European Norm EN (energy performance of buildings). This means you can design your plant optimally in terms of hydraulics and control thanks to the finely graduated range also for part load behavior such as summer/winter or day/night operation. This reduces energy consumption and thus operating costs. In addition, actuators with very short positioning times optimize the energy efficiency in fast controlled systems, in controlled systems with a high degree of difficulty, or in plants with very dynamic plate heat exchangers. The electrohydraulic actuators control very high dif fer ential pressures and large volumetric flows using little energy. And the highprecision, fast-acting valves with magnetic actuator save energy particularly in chilled water plants. eneration Distribution Consumption/Use 4

5 Investments that pay off in the long term Due to their rugged design and manufacture according to international production and testing standards, Acvatix valves and actuators have a particularly long service life. Thanks to their backward compatibility, they can be simply replaced with new products even after decades of operation. And that pays off also: Various auxiliary functions are available to increase the protection of plants and buildings, such as an integrated fail safe function in the event of a power failure, or position feedback and connection options for frost protection devices, for example. Convenient functions for any situation Based on the integrated position feedback of the actuators, plants can be monitored efficiently and faults rectified quickly. If individual plant components fail, the supply of heating or cooling energy can still be ensured thanks to convenient manual operation. Designed for installers and users With Acvatix you benefit from ease of service and installation. You can simply and cost-efficiently install and commission the actuators. The freedom from maintenance minimizes effort and operating costs. And manual operation with no need for additional tools assists you not only during commissioning, but also in unforeseen operating situations.

18 Acvatix for refrigeration plants Diverse choices for the supply and distribution of cooling energy or heat recovery Acvatix offers you hermetically sealed mixing, diverting and 2-port valves for refrigeration plants. These include refrigerant valves for expansion, hot-gas and suction throttle applications. All valves are compatible with stan dard controller signals 1) and operating voltages AC 24 V or DC V. reater energy efficiency for refrigeration systems All Acvatix refrigerant valves save energy in the refrigeration plant, for example through their accurate superheat control also in part load situations. In addition, the fine stroke resolution enables exact positioning and thus accurate and efficient energy control. Thanks to the positioning time of less than one second, you can handle even the most difficult control tasks reliably while saving energy. Benefit from your investments in the long term Rugged, long-lasting and backwardcompatible, the Acvatix refrigerant valves pay off for the long term. Their high efficiency and hermetic sealing reduce the amount of refrigerant, the plant size and thus the investment costs. Integrated functions provide added value by protecting the refrigeration plants and buildings. For instance, automatic, fast shutoff in the event of a power failure prevents the temperature and pressure from reaching excessive levels a safety function that products of other manufacturers can only ensure with additional plant components. Features for various comfort options and customer benefits To ensure that dynamic processes in refrigeration plants can be handled optimally with small amounts of refrigerants, all 2-port refrigerant valves have an integrated high-precision position controller with a stroke resolution of 1:1000. Simple and environmentally friendly The refrigerant valves are not only simple to install and maintenance-free, but also environmentally compatible: In all actuators the core is completely surrounded by a pressure tube. The magnet coil is located outside the refrigerant circuit, therefore the system is hermetically sealed. The magnet coil generates a magnetic field that is transmitted through the pressure tube, causing the core to move and thus the valve to travel. Refrigerant valves from Siemens do not have static or dynamic seals that could release refrigerants into the environment in the event of damage. Highlights Hermetically sealed refrigerant valves also in IP65 design Energy savings through accurate superheat control, very fine stroke resolution and positioning time < 1 second Long-term investment protection thanks to long service life, backward compatibility and protection functions Vibration-free operation, safe in the event of a power failure, and control of dynamic processes Ease of service and installation, and high degree of environmental compatibility 1) DC V; DC ma; DC V; DC ma 18
