ICV Intelligent Control Valves EnVisioneering how to bring new intelligence to systems using one of the oldest refrigerants—ammonia As an example of EnVisioneering at work, Danfoss uses innovative engineering to create an intelligent control valve that enables industrial refrigeration (ammonia) plants to standardize on a valve design for more reliable refrigerant regulation. |

Environmental Responsibility
It seems that ammonia should be the natural choice in refrigerants for industrial refrigeration systems. As a naturally occurring trace gas, ammonia does not impact the atmosphere. But to humans, a concentration of only 300 ppm is a health hazard affecting the skin, eyes, and lungs. That requires manufacturers of industrial refrigeration equipment to make sure the refrigerant is reliably regulated within the high-pressure systems used for cold storage warehouses and food processing. And that's why the Danfoss Intelligent Control Valve (ICV) is the technology of choice for pressure and temperature regulation in ammonia systems. |

| Engineering Innovations
The Danfoss ICV valve is the result of major research into what customers need in industrial refrigeration applications. The ICV valve body was designed with no internal wearing surfaces to allow the seat and all operating parts to be contained in a flexible, replaceable function module. This design allows technicians to upgrade to servo or motorized control without changing the housing. The design is available in both pilot-operated and digital motorized versions for industrial refrigeration suction pressure, hot gas defrost, compressor liquid injection, or direct expansion with common refrigerants at pressures up to 754 psig (52 bar). That makes the ICV valve easy to work with; and with ¼ the leak potential of traditional iron valves with flanges, it also makes it safer—a valuable combination of benefits recognized by the 2005 AHR Innovation Award.
