1- or 2-alarms Detectors

MGD-100

 

The MGD-100 gas detector from Murco / Bacharach Company is a cost-effective analog gas detector for the detection of a wide range of different gases. These detectors are adapted to work with Murco MGD controllers (two- or six-channel) and in this way can be integrated into the decided BMS (Building Management Systems), PLC or SCADA system.
High product quality, many years of practical testing and an affordable price are the factors that give the customer such safety and compliance with technical requirements.

MGD-100 gas detectors can be used in new buildings / spaces requiring continuous monitoring as existing buildings, where it is necessary to extend existing security systems with sensors and gas detectors.


Information on two- and six-channel MGD controllers is available in  Control Systems.


Typical applications:
• Detection of Refrigerants, including ammonia, carbon dioxide and gases from the group of hydrocarbons and hydrogen fluorides - HFCs, HCFCs, CFCs
• Detection of combustible gases such as: methane, LPG, propane, butane and hydrogen
• Detection of toxic gases such as: carbon dioxide and ammonia in refrigeration, hydrogen sulphide in sewage treatment plants, carbon monoxide in parking lots
Detection of volatile organic compounds such as: acetone, benzene, carbon tetrachloride, chloroform, ethanol, toluene, trichlorethylene.

Murco/Bacharach also offers control panels for the construction of standardized detection systems. The model range supports 2 to 16 channels.
An important argument for choosing a sensor is its compliance with applicable standards.
Murco sensors have the following approvals:
• Legislation: F Gas Regulation, EH40
• Standards: EN378, ASHRAE 15, ASHRAE 147
• Regulatory Approvals: UL, CE, CSA, IEC and EN

VALUABLE NOTICE:

The MGD-100 series detectors, as very few in the world, have LY (Lloyd's Register Type Approval System) certification in ENV1 and ENV2 environmental categories, thanks to which they can be successfully used on ships, ferries, cutters and other vessels.
