iACS - Experts in AHU Controls

Carel supplies a complete range of products that make use of the principles of evaporative cooling and all its advantages. The standard composition of these products is: - cabinet, containing the pump for pressurising the water, an inverter and an electronic controller for modulating the production of atomised water instant by instant; - atomiser nozzles, able to atomise the water into very fine water droplets (in the order of a few hundredths of a millimetre), extending the heat exchange surfaces. - distribution system, composed of stainless steel manifolds, atomiser nozzles and drain valves, in order to guarantee emptying. Advantages - energy saving: combines adiabatic humidification and evaporative cooling in a single global solution for energy saving within the AHU. - pressure loss management: optiMist guarantees real energy savings, assuring a very low pressure drop at the fans (30 Pa); -controlled atomisation: in order to completely exploit the potential of...

" Evaporative Cooling " is the process in which water cools the air through evaporation. For this to happen spontaneously, without the contribution of external energy, the water must be atomised in the air as very fine water droplets which, having a lower surface tension than the surrounding air, evaporate into the air. Why does the air cool down?  No contribution of external energy is necessary, however, owning to its nature, the water evaporation process requires a certain amount of energy. This energy is removed from the air itself which, in order to absorb the water must release sensible heat, thus lowering its own temperature. Every kilogram of water that evaporates absorbs 0.69 kW of heat from the air. This is how the dual humidification and cooling effect of the air is obtained through the Evaporative Cooling process, which in many air handling applications represent two desired effects. Energy Saving The rapid development of evaporative cooling in HVAC app...

i-A.C.Systems offers a range of sensors with different features for the various controllers , suitable for different applications mainly in the HVAC/R market sector. The accuracy obtained thanks to the technical solutions used in developing the sensor and the reliability as a result of the tests to which they are subjected, means that Carel NTC probes are reliable transducers for measuring temperature at a low cost. Probes for sockets assembly are available in strips for installation on pimping for pass-through with or without pre-heater, to measure the core temperature of the product, and a sensor for estimating product temperature. Technical Specifications: - Operating conditions: -50T105  ° C - Protection rating: IP67 and IP68 - Assembly: depending on model - Dimensions: depending on model

The use of a global monitoring and supervision system is always more essential, due to the necessity to manage alarms quicker and more efficiently and to optimise the routine and special maintenance of systems. In addition, standards in force and the trend towards energy saving make these systems a key to success and differentiation. Carel solves these requirements by offering field instruments fitted with RS485 interface for connection to local and centralised supervision systems. Depending on the various types of system and requirements, Carel offers: PlantWatchPRO: compact embedded solution for small refrigeration and air conditioning systems up to a maximum of 30 devices. PlantVisor PRO: embedded solution for medium and large systems up to a maximum of 300 devices. RemotePRO: software solution for centralised server in order to manage the system installed quicker and in an optimised manner. Advantages The Carel supervision system use modern WEB technology , maki...
