Eliwell LKD Next R32

LKDNext series leak detectors continuously monitor indoor air for refrigerant leaks. The devices can be used for refrigeration applications (cold rooms, freezer rooms, machine rooms). They are calibrated to detect most refrigerants currently available on the market. The sensitive elements are constructed using semiconductor technology (SC), infrared technology (IR) or electrochemical technology (EC).

LKDNext series detectors can be used in stand-alone applications or connected to ELIWELL controllers or third-party devices. Communication with controllers uses analog output, relays or serial RS485 Modbus connection and Bluetooth. When a refrigerant leak exceeding a programmable concentration threshold is detected, an alarm or warning state is activated, depending on the concentration level set, and the LKDNext responds as follows:

• The combination of lit LEDs changes
• A dedicated internal relay (SPDT) is activated
• The buzzer is activated
• The analog output is controlled (proportionally to the detected concentration)
• The change of state is signaled via the Modbus RS485 output and the Elwell Air applicationi In addition, the Eliwell Air App, available on the App Store and Play Store.

The LKDNext series detectors make it possible to comply with refrigeration safety standards (e.g. EN 378, ASHRAE 15) via alarms to alert personnel in the event of a refrigerant leak. The sensitive elements are constructed using semiconductor technology (SC), infrared technology (IR) or electrochemical technology (EC).
