    Description

    MLD series are unique smart refrigerant or flammable gas detectors used in HVAC-R applications as well as flammable gas leakages in industrial production sites. MLD Series is robust, extremely poisonresistant, factory-calibrated, with more than 15 years of lifetime expected without any recalibration process needed.

    Flammable gases are widely used across a variety of industrial and commercial applications, including hydrogen systems, fuel cells, gas storage and distribution, and industrial processes. While these gases offer important advantages in terms of energy efficiency and performance, their flammability requires reliable detection systems to help protect people, equipment, and facilities.

    Early detection of gas leaks is essential to prevent the accumulation of flammable gases and reduce the risk of fire or explosion. Gas detection systems must therefore provide reliable and continuous monitoring, even in demanding operating environments.

    The MLD gas detector is designed to detect a wide range of flammable gases, providing a reliable solution for applications where safety is a critical requirement. Based on advanced sensing technology, MLD offers long-term stability and continuous monitoring with minimal maintenance, helping to ensure safe operation across a wide range of industrial applications.

    The MLD series with NevadaNano’s Molecular Property Spectrometer™ (MPS™) Flammable Gas Sensors serves the needs of a wide range of industries with precise and dependable detection of most common flammable gases.

    Currently the MLD Flammable is ideal to detect butane, ethane, hydrogen, isobutane, isobutylene, isopropanol, methane, methyl ethyl ketone, octane, pentane, propane, propylene, toluene, xylene but check with GVZ Components for the latest list of detectable gas.

    Main Features

    Our industrial detectors employ smart sensor technology, ensuring consistent high performance and reliability.
    Utilizing smart sensor technology, the  sensors provide the following features critical to manufacturers and end users:

    • 15+ year sensor life provides maintenance free performance for the life of your equipment.

    • Factory calibrated with no field calibration needed for the life of the sensor ensures worry free operation.

    • Wide Environmental Operating Range: -40° to 70°C (12VDC), -40° to 60°C (24VDC) - 0 to 100% humidity, and 80 – 120kPa pressure) to ensure reliable operation in tough HVAC-R environments.

    • Built-in environmental compensation (T, RH, P) to provide measurement accuracy across the entire environmental range.

    • Inherently immune to poisoning to avoid degradation of the sensor and the need for replacement.

    • Intrinsically safe: CE, EMC, Rohs, IEC60335-2-40, EN60079-0, EN60079-11, ATEX, SIL1/2 according to IEC61508 / EN50402 / IEC 50271 / IEC 50270 (pending)

    Molecular Leakage Detector for flammable gas based on ultimate MPS™ technology.

    This flammable gas detector is a unique solution using the latest MPS™ (Molecular Property Spectrometry) technology to indicate the presence of flammable gases providing both a continuous signal proportional to the gas concentration and the activation via relay for alarming once a prefixed (and settable) level is reached.
    It combines all the advantages of MPS™ technology as in terms of long lifetime, no field calibration, built-in environmental compensation, no poisoning, wide temperature operating range and durability with a dedicated electronic board for easy interfacing the common control units thanks to the multiple outputs: Modbus, 2x Relays and 2x Analogue Output (ALL IN ONE).

    Carbon Footprint:
    The CO2 equivalent emissions in the production of a single MLD device is 1,588 kg.
    The carbon footprint of the MLDs is calculated by using the cradle-to-gate LCA (Life Cycle Assessment) method.
    This means that the system boundary include all greenhouse gas emissions that occur from the input of raw materials (cradle) to the end of the product’s production (gate).
