Air Treatment Units: The MasterAria

By Anonymous -


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.

CAREL and the dreaded 'NO LINK' Screen! Picture the scene, you've just downloaded a fresh new piece of software onto a controller but rather than the a new interface, you're met with a big fat 'NO LINK' message on the display. Or maybe you've just ran a factory reset to default settings and have come up against the same issue?  These are all possible causes for the common problem encountered by many of our customers, deemed the 'NO LINK' screen! (capitals for emphasis) As well as the two already mentioned, other common causes of the issue are a result of: A faulty connection between the Controller and the Display A faulty Controller  In any case, this issue is relatively simple to fix and our Managing Director, Stefano - having been in the Industry for 15+ years - has put together a video guide on how to do so. Watch the video below to see how to overcome the dreaded 'NO LINK' Screen!   www.i-acs.co.uk

Cold Rooms for food storage

Food storage uses various procedures that vary based on duration: Refrigeration, if the food must be stored for a short period of time (0…7 ° C). Freezing, deep freezing and lyophilisation (freeze drying) if it must be stored for long periods. When deep freezing the product it must reach a temperature of -18 ° C in less than 4 hours while for regular freezing the product can take more than 4 hours to reach -18 ° C. During lyophilisation the product is dried following a forced evaporation of the water component of the product. In the food industry, refrigeration is one of the most delicate and complex applications because food requires treatment at different temperatures depending upon the processing phase. Refrigeration slows the growth of bacteria on food. The technique is based on the extremely quick and intense action performed by the cold temperature that allows the organoleptic qualities of the food to be kept intact, prolonging storage time. Systems...
