2 PRODUCT DESCRIPTION
2.1 Intended use / Applications
The GLACIÄR MIDI 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 GLACIÄR MIDI 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 GLACIÄR MIDI series detectors can be used in stand-alone applications or connected to SAMON controllers or third-party devices.
Communication with controllers uses an analogue output, relays, or an RS485 Modbus
®
serial connection.
When a refrigerant leakage exceeding a programmable concentration threshold is detected, an alarm or warning status is activated, depending
on the level of concentration set, and the GLACIÄR MIDI responds as follows:
• The combination of LEDs that are on changes
• A dedicated internal relay (SPDT) is activated
• The analogue output is controlled (in proportion to the detected concentration)
• The change in status is signalled via the RS485 Modbus® output
Furthermore, the “SAMON GLACIÄR” app, available in both App Store and Play Store, can be used to access the device.
The GLACIÄR MIDI series detectors enable compliance with refrigeration safety standards (e.g., EN 378, ASHRAE 15) through alarms to alert
personnel in the event of a refrigerant leakage.
WARNING: semiconductor sensors detect the gas they have been calibrated for, but are also sensitive to other
types of gases, solvents, alcohol, or substances containing ammonia, such as cleaning products, present in the
environment. This, in certain areas and applications, can lead to false alarms when the substances described
above are present. Nonetheless, although they do not only detect the specific gas, but they also still give a
reliable indication of the concentration of the gas they have been calibrated for.
WARNING: This device is neither certified nor approved for operation in oxygen-enriched atmospheres. Non-
compliance can lead to EXPLOSION.
WARNING: This device has not been designed to guarantee intrinsic safety when used in areas classified as
hazardous (“Directive 2014/34/EU ATEX” and “NFPA 70, Hazardous Location”). For operator safety, DO NOT use it in
hazardous locations (classified as such).
If the equipment is used in a manner not specified by the manufacturer, the protection provided by the
equipment may be impaired.
GLACIÄR MIDI is available in five main versions:
• Infrared version for CO2
• Electrochemical version for Ammonia
• Semiconductor version for R32 refrigerant gas blends
• Semiconductor version for HC refrigerant gases
• Semiconductor version for HFC/HFO refrigerant gases
