DANFOSS Introduces HIGHER MOPD, UL Approved Coils for Use in High Pressure CO2 Systems

Press release date: Jul 21, 2014

Danfoss adds higher maximum opening pressure differential (MOPD), UL approved BJ and BX coils to its existing product line.  These higher MOPD coils are ideal for use with Danfoss AKVH electronic expansion valves to meet the rigorous demands of high pressure CO2 systems.

As part of a continuous effort to improve the North American CO2 product portfolio, Danfoss introduces six higher MOPD, UL approved BJ and BX coils. These new coils have larger pulling force which enables larger AKVH valves to operate in CO2 systems. Similar to the current BJ and BX coils on the market, these higher MOPD BJ and BX coils feature a redesigned frame and robust encapsulation, for extended lifetime and durability, as well as a clip-on fastening system with an audible latch click to minimize installation time and ensure proper installation of the coil.

The following specifications are based on the requirements of North American food retail systems.

Basic specifications:

Design in accordance with UL 429
Tested in harsh operating conditions from -40 – 122 °F
O-ring between coil and valve removed, for easy installation
Clip on function for secure connection
Redesigned frame, robust encapsulation
Covering standard voltage and frequency; two electrical connection versions

Advantages include:
Faster installation, without the use of tools, with clip-on function
More accurate installation with audible latch click
More reliable operation with durable frame and robust encapsulation
Widely available making logistics easier for the customer
Complete product portfolio of valve and coil combinations for a range of standard and alternative refrigerant needs
