The connection of the controllers into networks means that one single supervisory station can manage the parameters and information required to identify the status of the devices present and the processes being controlled. The data collected (temperature graphs, fault signals, service requests, etc.), which can be displayed by the user simply and quickly, are saved and can be made available to access the information saved via a remote connection, in order to analyse or check the correct operation of the system. They can consequently modify the control parameters, modify or force the operating modes, or directly manage any actuators. When required, it is the system itself that alerts the appropriate service centre. Event synchronization The individual control actions can be co-ordinated so as to be performed at certain times and in certain ways, in order to minimise any negative effects on the overall system. One example is the division of the loads due to the defro...

BMS (Building Management Systems) are systems for the integrated management of all the technological functions of a building, including access control, safety, fire detection, lighting, intelligent elevators, Air-Conditioning, etc. The development of these systems has meant that control systems made by different companies often need to be connected together, and consequently and consequently not only is a common electrical standard required, but also a common language, or communication protocol.  The resulting advantages of such solutions (simpler and more efficient management of the building from a single control station, reduction in running costs, possibility of statistical analysis of all data, immediate identification of and response to faults and alarms, etc..) amply justify any extra cost of the individual devices. Today, then, not only are the quality and the reliability of the instruments important, but also the degree of external connectivity they can offer....

All the CAREL immersed electrode humidifiers feature sophisticated control software that automatically adapts the operating parameters to the characteristics of the water; nonetheless, the optimum balance between duration, variation of steam production and speed of response depending on the type of water and the power supply can only be achieved by changing the shape and the position of the electrodes. For this reason, the Carel immerse electrodes humidifiers today feature the widest choice of cylinders , with specific electrodes for water with conductivity between 125 µS/cm and 1250 µS/cm, for capacities between 1 and 65 kg/h, and for power supply voltages between 200 V and 575 V. This extraordinary range of cylinders is the result of years of research and tens of thousands of hours of tests in the Carel Humidification Laboratory under the widest possible range of uses. This ensures the right solution in every circumstance. All the humiSteam cylinders feature large galvanised elect...

Belimo has developed a unique system, the world's first ever 6-way characterised control valve, that guarantees finely balanced control of chilled and heated ceilings. Sustainable well-being hinges to a large extent on a permanently comfortable room temperature. In a growing number of non-residential building, this is achieved by utilising the exchange of heat or cold between the ceiling and the room air. Belimo has solved this dilemma: in combination with the new CRK24-B1 room temperature controller, the world's first ever 6-way characterized control valve guarantees finely balanced control of chilled and heated ceilings. Cost and energy economies The only one of its kind in the world R3015-X-Y-B2 (DN 15) and R3020-x-y-B2 (DN 20) 6-way characterized control valve s are specially designed for use in chilled and heated ceilings. The incredibly compact valve unites the functionality of up to four straight-through valves. Space, material and installation time are s...

The CAREL E²V smart series electronic expansion valves bring together the renewed reliability of the Carel E²V and the versatility of a removable cartridge, plus the option of a convenient integrated sight glass. The motor block can be dismantled to simplify welding, thus preventing the risk of overheating and damage. A movable element with Teflon gasket, plus a calibrated spring seal mechanism, are the heart of the CAREL system that ensures unrivaled tightness, meaning the valves can work with very high pressure differentials. E²V smart also offers a removable metal filter to trap solid residues that may damage the valve or cause a decline in efficiency. The family of E²V smart valves comes in 8 sizes and covers a wide range of capacities: •    Air-conditioning: 0.3 to 58 kW •    Refrigeration: 0.15 to 38 kW Technical specifications Limit pressure values: •    Maximum working pressure (MWP): 45 bars (653 psi) •    Maxim...

Ultracap is the new emergency power supply device for electronic valves , the natural completion of the EVDEvo, both single and twin versions, ensuring complete closing of the valves even when there are mains power failures. Exploiting ELDC (Electric Double Layer Capacitor) technology, Ultracap can supply immediate, reliable and clean emergency energy, representing a major step forwards compared to conventional battery-based systems, including as regards disposal of used materials. Ultracap has been designed to give 10 years trouble-free silent operation, without requiring periodical checks or having to replace batteries. Ultracap means immediate energy: just 5 minutes (4 minutes for Carel valves) after power is restored, the system is already recharged and active (in practical terms the same time the compressor takes to start...). The extreme reliability of Ultracap combined with the exceptional tightness of Carel valves , eliminates the need for solenoid valves even in the m...
