MILAN (ITALY)/BIRMINGHAM (UK) March 27/13, 2012 – Emerson Climate Technologies has introduced two new controllers to the market. EXD-HP1 and EXD-HP2 are predominately designed for superheat and economizer control with Emerson stepper motor driven electronic expansion valves EXM/EXL. EXD-HP1 is the standard solution for heating applications in conjunction with Copeland Scroll™ compressors, especially with liquid and vapor injection. EXD-HP2 is capable of driving two individual EXM/EXL electronic expansion valves. It is the first standard product on the market to fulfill liquid and vapor injection requirement of the new Copeland heating scroll compressors. Conventional heat pumps, rooftop units, precision cooling and medical equipment cooling are further ranges of applications suitable for using the new devices.
These are the only superheat controllers with automatic control behavior which do not require PID to be set for individual series of systems. They are simple and easy to install for standalone solution. In addition they offer communication with third party controllers as slave via Modbus (RTU). All variable data as well as configuration parameters are accessible. EXD-HP1/2 support a lot of monitoring and alarm functions, such as low pressure switch, freeze protection function, limitation of the maximum evaporating pressure (MOP), low/high superheat alarm or monitoring of sensors and sensor wiring as well as the detection of sensor and wiring failures. An optional programming key allows copying of configuration parameters from one EXD-HP controller to others.
