The new EVD evolution driver has been enhanced with advanced functions and a new user interface that makes it even easier to use and configure:

• Superheat control with auxiliary high pressure, low pressure and low superheat protection
• Start-up with just 4 parameters: refrigerant used, model of valve, type of pressure sensor and application (chiller, showcase, etc.)
• New battery module
• Twin version to control two valves
• Self-adaptive algorithm
• Algorithm for Digital Scroll applications
• Connection diagram visible on the display
• Removable multi-language graphic display, with "help" on the parameters
• Multiple units of measure (metric or Imperial)
• User management with passwords for accessing different levels of configuration
• Copy parameter values to other EVDs using the display
• LEDs for monitoring the main parameters
• Use of ratiometric or 4 to 20 mA transducers (the latter can be shared between multiple drivers)
• Second digital input for defrost management
• Possibility to use backup sensors
• Serial communication protocols: CARELmaster, pLAN Modbus®
  The new TWIN version can independently control two electronic expansion valves, and represents the ideal solution for two circuit units or different control functions (i.e. superheat and hot gas bypass). Connected to a pCO series controller, EVD Evolution can manage superheat on units fitted with Digital Scroll compressors, using a specific algorithm patented by CAREL and approved by Emerson Climate Tech.
