This document discusses Carel's ExV Sistema electronic expansion valves. It notes that the document and its contents are confidential and for internal Carel use only. It provides information on the components of the ExV Sistema, including electronic expansion valves, EVD drivers, pressure and temperature probes. It compares ExV Sistema valves to traditional thermostatic valves, noting advantages like improved performance, food quality, energy savings, reliability and usability of ExV valves. The document also provides guidance on selecting the appropriate expansion valve and EVD driver for cold room design applications.
