iACS - Experts in AHU Controls

Heat exchangers in general, whether for air/air applications or air/water applications (i.e., condensers), have a considerable weight in terms of efficiency and energy yield. Even this element, which is essential for the correct design of the chiller cycle, must be properly managed and therefore requires electronic regulation. The advent of electronically controlled brushless motors allows the refinement of the adjustments and noise reduction. Carel offers a series of programmable controllers (pCO) that allow serial piloting of these loads, thus reducing the space, wiring installation complexity in general, allowing the management of a large amount of information in real time and rapid intervention in the event of anomalies or failures. This is not the only option to satisfy the market: Carel completes the offer with the gamma inverter and is thus able to meet all of the customer’s needs. Built-in at either the panel level or for the entire solution, it is theref...

When talking about refrigeration and air conditioning , how many installations are there throughout the world? The number, if it exists, is definitely huge. Retrofitting old systems, required in order to comply with the new environmental directives but also seen as a commercial opportunity, is definitely interesting. Performing a retrofit on an existing system with the objective of implementing continuous and detailed monitoring in compliance with HACCP regulations allows the user to: -control the temperatures of the all ready functioning chiller utilities with low impact systems, avoiding the replacement of the electronics installed on the utilities themselves; -limit the amount of wiring by taking advantage of wireless technology and thus significantly reducing installation costs; -simplify data registration procedures; -register and monitor the data related to the system -prevent and/or identify possible critical events and automatically advi...

The panels in the Masteraria series are perfect for the  management of standard AHUs which require the management and supply of two fans, a utility for heat recovery, a possible outer electrical load and actuators , valves , probes, alarms, and safeties limited to the number of inputs and outputs of the electronic controller. The Masteraria solution is created inside a fibreglass case with two doors (one of which is transparent) suitable for installations from -25 to 60 °C, very sturdy and impact resistant (IK10), with glow wire 650 °C, IP 65 protection rating. Each case is equipped with its own wall installation kit with threaded holes already in place on the bottom. The general electrical sectioning of the panel is located on the inner door, with front control using a rotation handle.   In the same manner the user interface is located on the inner door, easily removable with the knife switch closed, to allow easily cabling and start-up. Besides the detailed elect...
