Industrial processing

Image
  Processing temperature control needs a wide range of technologically advanced products, from the simple thermostat with PID and autotuning to programmable controllers and with graphical user interfaces and touch screens to simplify operations for the user. Processing temperature control In industrial processes there are many components which make use of temperature control: temperature controllers for plastic moulding units; dryers for plastic or compressed air, enclosure air conditioners for electrical cabinets, and chillers and cold water production systems (e.g. adiabatic cooling systems). To meet these extremely varied needs, Carel offers a range of controllers and user interfaces, from the simple thermostats to the pCO5 + series programmable systems, with its graphical user interfaces and touch-screens. Engineering The complexity of temperature control in industrial processes can be addressed using universal controllers with 1 or 2 loops only in the sim...

Datacenters-precision air conditioning

Image
Air conditioning is one of the essential infrastructures for the operation of Information Technology equipment: processing and storage devices produce heat which has to be removed to maintain optimal operating conditions. Increasing use of IT technologies in every activity has made the continuity of service imperative, often spoken of as "Mission Critical" applications. The high power installed, up to 2 kW/m2, also requires the development of "Energy Saving" solutions. For the proper functioning of IT equipment, the inlet air must be at a controlled temperature (typically between 22 and 27 °C) so that the fans of the devices can cool the chips inside. Moisture is also frequently controlled, since values that are too low increase the probability of electrostatic discharge while any excessive values accelerate corrosion or slow down the performance of some equipment. The technological solution most widely used today is the so called Computer Room Air Conditioner ...

Connectivity

Remote management and communications solutions Leader in controlling solutions for HVAC/R units, CAREL offers the market a product that is the expression of years of experience acquired in the design and production of programmable controllers .  With Connectivity , CAREL is continuously engaged in technological evolution in remote management and communication solutions, paying attention to certain fundamental concepts. Connectivity Interfaceability and compatibility with the most widespread BMS (Building Management System): BACnet , LonWorks, Modbus, Konnex, SNMP . It thus becomes easy to: manage the unit remotely via modem and Internet, even with a simple browser; inform authorised personnel, wherever they might be, of any alarm situations, even via SMS and email; construct alarm logs and graphs for prompt unit diagnostics. Interoperability The ability to work in distributed intelligence and with integrated solutions, acquiring and shari...

The EVD Evolution

Image
Based on CAREL’s extensive experience in electronic valve drivers , EVD evolution is available as a “single” and “twin” driver, the latter able to control two valves independently, with the most commonly used refrigerants. Simple graphics and a series of LEDs offer an immediate overview of operating status and the main driver functions. The EVD evolution offers: High Performance : Sophisticated control functions and construction with advance materials for optimum management of refrigerant flow, even in the most critical conditions. Multilanguage : System easy to understand and configure, with eight languages available in addition to english.   Reduced Environmental impact : Compatibility with natural refrigerants  ( CO 2 ) and energy saving help reduce ozone layer depletion and greenhouse gas emissions. A powerful removable graphic display ( EVDIS**0 ) can be used to configure the driver, providing clear and immediate information on operat...
