Serie EWNext Performance/R
Energy Labelling and Ecodesign for sustainable refrigeration
Applications
The EWNEXT Performance family of controllers is being expanded to include the new /R models, designed to manage LED power supplies and electronic valves. The low consumption of these load types means that they are increasingly used by manufacturers so that their equipment is able to attain a higher energy rating.
The range consists of various models that can be used to manage up to two electronic loads: you can also choose between removable or screw terminal blocks, a 230 Vac or 115 Vac power supply and a buzzer or RTC.
Compatibility with the TelevisAir monitoring system is established as standard for this family of controllers.
EWNext Performance controllers are designed to combine significant energy savings with the ultimate in easy installation and use, and can easily take the place of devices belonging to previous series of controllers.
Thanks to the versatility of the platform and a library of available functions, Eliwell can design custom solutions to suit energy saving requirements while simplifying production processes.
- Advanced control algorithms for energy saving with no need to change the counter structure
- Automatic adaptation of the energy saving functions based on refrigerator usage conditions
- The product is compatible with the new ecological refrigerants R290 and R600, in compliance with IEC 60079-15-2005
- Optimised temperature management when switching from night to day mode
- Management of a 2nd compressor on the basis of a delay period
- Modular defrost management
- Advanced algorithms for defrost management on the 2nd evaporator
- Management of VSC variable speed compressors (depending on the model)
- 3 easily selectable, pre-loaded configurations with default setting restore option
- Deep cooling controller
- Internal RTC (depending on the model)
- Low Voltage Detector (depending on the model)
- Synchronised defrost from digital input (depending on the model)
- Compatible with the new remote display ECNext redesigned with the same look and feel as the EWNext controller (depending on model)
- Can be connected to the BTLE AIR Dongle and the TelevisAir cloud solution
- Green Premium product
- Extended warranty
- IP65
