E2V proportional electronic expansion valve

Image
Carel electronic expansion valves E2V with proportional modulation and excellent technical and functional characteristics, allow an efficient control of refrigeration and air-conditioning units , and consistent energy saving performance. The flow of refrigerant is modulated by nozzle coupled to a torpedo shaped aperture, measuring more than 15 mm long, over a wide operating range. The internal mechanism is fitted on a calibrated spring with ball bearings and guarantees a stable and reliable regulation reducing the risk of failures. E2V is completely manufactured using laser-welding techniques on high-quality materials (AISI 316L), as well as technopolymers. Carel has paid special attention to the smallest details in designing E2V to ensure very high reliability for operations up to 35 bars of differential pressure and up to 45 bars of absolute pressure. Other features include exclusive axial motion of the nozzle aperture and seal gasket in the closing position. By install...

Display Case

Image
The chiller utilities are an essential part of the refrigeration system and as such must be given the best solution available that allows state of the art performance and flexibility. Each controller dedicated to the utilities must ensure the correct storage temperature and monitor the operating conditions. However, in addition to ensuring the basic necessities, the CAREL retail system pays special attention to energy savings and reliability. There are solutions available that allow for high performance operation, with a subsequent reduction in energy consumption, and greater control with back-up procedures in case of anomalies, and thus greater security. In the food industry, refrigeration is one of the most delicate and complex applications because food requires treatments at different temperatures depending upon the processing phase. Refrigeration slows the growth of bacteria on foods. The technique is based on the extremely quick and intense action performed by the co...

The Masteraria AHU controls on the Wellington Arch

Image
The Masteraria Control panel for AHUs installations are spreading out across the UK territory on very prestigious building sites. The latest installation last month has been on the Wellington Arch , in the heart of London, right next to the Royal Palace. The Carel Electrical panel, equipped with a PCO3 controller ,  manages the thermo-higrometric conditions in the building guaranteeing a precision control. The dampers, Heating coils, the DX condensing units, are controlled by Masteraria panel making sure that the overall running efficiency of the AHU package it's at its best.  Thanks to the 3 embedded comms ports of the PCO3 controller and the hi-tech MODBUS integrated Inverter (VFD) management of the new AHUE software, the Masteraria panel monitors the fan speed and airflow through a Modbus interface link, making available the inverter references straight from the semi-graphical, intuitive and user fridley display of the AHU controls. ...

Electronic Expansion Valves and Drivers

Image
Technology The ExV family valves manage refrigerant expansion through a variable valve port, created by a fixed calibrated opening and a canonical movable element. The linear movement of the closing element is achieved trough the combined action of a stepper motor and a worm screw transmission, which produces precise and regular movement by minimising friction. Control precision and stability are ensured by rotating elements supported by stainless steel ball bearings. The entire mechanism is very robust, thanks to the motor block suspended on harmonic steel springs, and a technopolymer chassis that guarantees high mechanical performance and light weight. All this is made possible my careful construction, the use of quality materials, and a production process with final testing on each and every product, in accordance with the highest quality standards. Performance The care paid to the design and  production of our valves ensure market-leading performance: high ...

The New 2 Way Characterised Control Valves

Image
Belimo is now offering a convincing alternative to the heavyweight Globe valve actuator combinations: The extremely compact characterised control valves ( CCV ) with nominal diameters of DN 65...150 are up to three times lighter and lead to a reduction in operating costs.     More compact, lighter, better The product range of the globally unique Belimo characterised control valves is being expanded further: New flange versions in nominal diameters of DN 65 up toDN 150 control even larger sized volumetric flows with the highest of precision. Their patented characterising disk ensures an equal-percentage valve characteristic curve. Thanks to the simplicity of their construction, the characterised control valves are pressure-compensated and therefore require no holding torque when in closed position. Furthermore, because they close air bubble tight, an energy saving of up to 40% can be achieved during operation. Economical alternative The new characteris...

Introducing The New NF/SF and The New EF Spring Return Actuators

Image
An absolute novelty, the NF/SF new-generation spring return actuators are based on the functionality and design of the AF actuators. They are powerfully motorised and now protect your units better than ever before. Safe, strong and reliable the NF/SF actuators now have versions available wth Universal Voltage.  In case of a voltage interruption, the dampers or valves coupled with the actuator are moved automatically into the predefined emergency setting position. Belimo now offers the new EF spring return actuator with a torque of 30Nm, that makes it the most powerfull model in the product range of general spring return actuators rounding out the array upwards in all of its characteristics. Predestined for utilisation on large air dampers, the EF is thorough in the performance of its task, even under difficult conditions, thanks to such options as higher degrees of protection and integrated heating. It is robust, stable, versatile and reliable.

The new generation of Microchiller Controllers

Image
The new MCH2 controller has joined the wide range of Carel’s air-conditioning products: the μC2 is a new compact electronic controller, the same size as a normal thermostat characterised by a modern ergonometric display, for the complete management of chillers and heat pumps: it can control air-air, air-water, water-water and condensing units. The μC2 main functions are: control of the water inlet and evaporator outlet temperature defrost management by time and/or by temperature or pressure fan speed control complete alarm management connection to serial line for supervision/telemaintenance elimination of the expansion vessel. The current MCH2001030 as a replacement of the MCHCOMP1A0 can manage up to 4 hermetic and 2 semi-hermetic compressors for a total of 2 circuits, with the possibility to manage one electronic expansion valve per circuit reduce thus energy consumption and the production costs of the OEMs.
