Modern safety solutions for the refrigeration industry

Refrigeration is essential across many industries and areas of applications. While the food industry is certainly the most prominent of them all – with storage, transportation, numerous production processes and other factors requiring various forms of cooling – there are many other applications for freezing solutions as well. From cooling certain delicate parts before they can be used in engineering or manufacturing processes to facilities in the medical and chemical sector keeping their substances at the exact temperature they need to be.

While many are aware of the obvious dangers that come with handling freezing agents or working in cold storages, such as frostbite or oxygen deficiency caused by liquid nitrogen, many overlook the silent, invisible dangers that freezing and cooling solutions can cause. These include combustible and toxic gases, work in confined spaces, the hazards caused by refrigerants, carbon dioxide and more. The risks themselves cannot be avoided, but their consequences can be reduced – with the right equipment.

GfG offers both fixed gas detection systems and portable gas detectors for personal protection. Our fixed gas detection systems consist of a controller and as many transmitters as your area of use requires. They are perfect for monitoring manufacturing processes or any other long-term installations using dangerous gases or vapors.

Our IR22 F transmitter was designed specifically for reliable use in applications with ambient temperatures of up to -40°C. It measures the concentration of carbon dioxide, one of the most common gases in refrigeration processes, and transmits the measured values to the central controller of your gas detection system either via analog (4-20 MA) or digital (RS-485) signal. The controller will then sound an alarm immediately. For local alarms, the IR22 F has an internal relay which can be connected to an alarm signal of your choosing.

The CS22 D transmitter uses the chemisorption method to detect a wide range of combustible and toxic gases, such as ammonia, methane and many common refrigerants. It will display the current measured value locally on its 2.2-inch backlit display and uses both visual and acoustic signals to indicate alarms.

For very humid environments, GfG also offers numerous water measurement solutions. Our MiniCal III uses an ion-selective measuring method detect ammonia leaks in cooling circuits as quickly as possible and thus prevent consequential damage to your production process. The MiniCal III system will detect leaks even in the smallest concentrations, whether in water basins and circuits or brine mixtures, such as ethylene glycol, propylene glycol or Tyfoxit. To perfectly tailor the MiniCal III to your application, a number of different accessories are also available. These include bypass fittings, flow fittings, or immersion fittings, different filters, buffers, plugs valves and much more.
