Install the sensor inside the room at a proper height depending on the refrigerant. Being gases heavier than air, it is normally recommended to position LKDNext sensor lower than the average height of people inside the room. With heavier than air gases such as halocarbon and hydrocarbon refrigerants such as R404A, propane, and butane sensors should be located near ground level. With lighter than air gas for example ammonia, the sensor needs to be located above the equipment to be monitored on a bracket or high on a wall within 300 mm of. With similar density or miscible gases, such as CO2, sensors...

The LKDNext series leakage detectors continuously monitor indoor air for any refrigerant leaks. The devices can be used for refrigeration applications (cold rooms, freezer rooms, machinery rooms). The LKDNext series detectors are available in the following configurations: • Built-in version • Remote version They are calibrated to detect most refrigerants currently available on the market. The sensitive elements are constructed using semiconductor (SC) technology, infrared (IR) technology, or electrochemical (EC) technology. The LKDNext series detectors can be used in stand-alone applications...
