A simple and effective solution to chlorine generation

Chlorine (Cl2) has always been a difficult gas to handle when using traditional gas cylinders. It is very reactive and problematic in terms of accuracy and its erratic shelf life. This has made life difficult for personnel working across a wide range of industries, such as in the water treatment sector.

With this in mind, Euro-Gas designed and developed their GazCal Gas Generator, which is now an indispensable tool for people working with chlorine gas. Engineers within the water industry find this rugged, portable and battery-operated tool ideal for testing and calibration, both in the lab and in the plant. The GazCal comes in a robust and compact carrying case and enables rapid testing and calibration with negligible warm-up time. This simple to use device can be operated by anyone! Simply set the necessary PPM level via the unit’s dial-up digital display and it is ready for action. The Gazcal generates Cl2 levels ranging from 0.5 – 20 ppm and is also suited to act as a surrogate for the cross-calibration of O3, ClO2, COCl2, HF and F2.

Euro-Gas have designed the GazCal to overcome the usual problems of a low shelf life. Cell life is only used up when the unit is in operation, whilst traditional cylinders can simply die out after up to 6 months. The generator can therefore last for up to a decade, often without the necessity to change the cell and needing only a yearly recertification of calibration, which can be carried out by Euro-Gas or qualified technicians at the site.

The GazCal cell has a lifetime of 500ppm hours, equating to 100 hours of constant use at a 5ppm concentration level, which enables a minimum of 400 individual calibrations. Operators can see the life span of the generating cell on the unit’s cell life indicator. Once the cell is used up, a new generating cell can be installed easily. Depending on the level of experience that the engineer has with gas detection calibration, regular small gas cylinders will usually only perform around 5 – 10 calibrations per cylinder. The GazCal may initially be more costly than a small cylinder but in the longer term, the generator will be far more economical.

Moreover, gas cylinders only attain one specific concentration per cylinder purchased, say for instance 5ppm of Cl2, whereas the GazCal is totally adjustable between the 0.5ppm to 20.0ppm range and in 0.1ppm steps. Therefore, the Gazcal produces many different concentration levels from one device. In addition, low concentrations of Cl2 are efficiently produced with the GazCal, even 1ppm and 2ppm levels, whereas it is extremely problematic to achieve cylinder stability at low concentration levels.
