Air Treatment Units: The MasterAria

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 electrical diagram, provided as standard equipment in paper format, a quick diagram is also made available on glossary adhesive paper and located on the back of the inner door.

The core of the Masteraria are the thermal protections for the motors, made up of a fixed, wired base and the plug & play thermal modules chosen based on the size of the fan. Thus, the Masteraria has become a true shelf product since for each project, the only variable to be chosen will be which module to install, in just a few seconds, based on the already wired motor protections inside the panel.

The wiring plate also has four power terminals to supply an external electrical utility (step deck battery, modulating battery, condensing unit, humidifier,…): the paper electrical diagram, with two tables, show the maximum external electrical load that can be supplied through the support terminals according to the size of the fans installed. Also, all of the inputs and outputs are linked to the support terminal board in order to be able to take full advantage of all the potential of the system pCO.
