The pCO sistema

By Anonymous -
pCO Sistema is the result of Carel’s long experience in the design and manufacture of programmable controllers for HVAC/R units.
The pCO sistema, first developed by Carel in 1984, now offers many more benefits to the manufacturer of Air-Conditioning and Refrigeration units and plants.
The pCO Sistema consists of programmable controllers, user interfaces, software tools for the development of applications, gateways and communication interfaces, remote management systems, and a series of optional boards to interface to the more commonly-used Building Management Systems together with a proprietary supervisory system. A system that guarantees reliability, while being easily modifiable, so as to differentiate the control of air-conditioning or refrigeration unit in terms of both appearance and functions.
The pCO sistema family controllers come in a number of sizes, according to the number and type of inputs/outputs, the use of the Built-In terminal, and the size of the flash memory available.
Everything required to offer the OEMs working in HVAC/R a control system that is powerful yet flexible, and can easily be customized in both aesthetic and functional terms using EasyTools or uploading directly to the pCO, setting the parameters for the appropriate configuration of chillers, heat pumps and condensing units:

- water cooled
- air cooled
- up to 4 circuits
- up to 8 compressors.

The standard application programs have been designed to make a modular solution according to needs. This means that a series of pCO platform controllers can be connected together via a pLAN network of up to 8 units.
Sophisticated algorithms have been developed to offer customers the most advanced solutions for screw compressors, semi-hermetic and scroll compressors.
Specifically for Bitzer Screw Compressors and Turbocor centrifugal compressors, CAREL provides a Driver that optimises performance and protects against dangerous suction and discharge pressure conditions.
Moreover, all the controllers can be fitted with accessories that ensure the maximum performance and energy savings, such as the electronic expansion valve, the 4 to 20 mA or ratiometric pressure transducers.

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

By Anonymous -

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...
