Temperature and superheat control EX2 valve (temp/temp) for power rack systems, incl. K02-000, ECN-F60, 4x ECN-P60, ECT-523. The EC2 series is the current generation of electronic controllers for refrigeration and air conditioning. Maximum functionality in a small package: Superheating regulation, temperature regulation and defrosting control, a TCP/IP Ethernet communication interface and web server function. All monitoring and configuration tasks can be performed from any normal web browser (e.g. Internet Explorer® or Mozilla Firefox). The version using the Echelon LON® network protocol is used in more complex systems to enable communication between controllers.
This series includes the following variants:
- EC2-35/37x cooling controller (EXV, pressure / temp.)
- EC2-31/39x cooling controller (EXV, temp. / temp.)
- EC2-21/29x cooling controller (TXV)
- EC2-11x universal regulator
Features
- Self-adjusting superheat control for electrical pulse width modulation EX2 control valves from ALCO (EC2-35/37x & EC2-31/39x)
- Air temperature regulation
- Defrosting control for natural, electrical or hot gas defrosting with fan speed regulation (except for EC2-111/-112)
- Evaporation temperature ...
