Nanjing JLHB Environmental Technology Development Co., Ltd is specialized in refrigeration equipment production in east China and Jiangsu province. After years of stable management, it now has a great reputation among customers. It has one business hall(located in No.34, Huju South Road, Nanjing, covering about 500 square meters) and two factories(one is located in Yongyang Industrial Park, Lishui, Nanjing with an area of 20000 square meters, mainly manufacturing heat exchangers; another is in No.36, Runqi Road, Jiangning, Nanjing with an area of 4000 square meters, mainly producing refrigeration units). It also has branch companies in Shanghai, Guangzhou, Shenyang, Hefei, Wuhan, Changzhou etc. Our two main products are all authorized the ISO9001:2000 Quality Management System Certificate and we established an Automatic Unit Inspection Station (a national-level experimental center) with Hefei General Machinery Research Institute. 

 EC3-X32 is a stand-alone universal superheat controller for air conditioning, refrigeration and industrial applications such as chillers, industrial process cooling, rooftops, heat pumps, package unit, close control, cold room, food process and air driers. EC3-X32 offers remote access with built-in TCP/IP Ethernet communications and Web Server functionality. Any standard Web Browser (e.g. Internet Explorer 5.0 or higher or Mozilla Firefox) can be used for monitoring or parameter setting.

Features

1.EC3-X32 Superheat control in conjunction with Emerson stepper motor driven Electrical Control Valves (EX4 … EX8)

2.Limitation of evaporating pressure (MOP) Low and high superheat alarm

3.Low pressure switch function/alarm; Freeze protection function/alarm; Pump down function

4.Feed through of 4…20mA signal from evaporator pressure sensor to analogue output. This may also be connected to pressure input of any other controller to avoid need for multiple pressure sensors

5.Monitoring of sensors and sensor wiring and detection of sensor and wiring failures

6.Intelligent alarm management in order to protect the compressor i.e. fail safe operation

7.Integral rechargeable battery to close Electrical Control Valve in case of power loss

8.Support of TCP/IP Ethernet technology with Web Server functionality allows monitoring and configuration of controllers through a standard Web Browser (e.g. Internet Explorer5.0 or Mozilla Firefox)

9.Electrical connection via plug-in type screw terminal;

10.Aluminum housing for DIN rail mounting
