Introduction /Enclosure/Hausing

The EnCal 3000 is an on-line gas chromatograph. The device is fully automatic and is
enclosed in a tailor-made Ex-d housing which contains the electrical and analytical
equipment. The explosion-proof aluminium housing essentially consists of a low base
on to which a relatively high hood/cap is screwed using an M270 thread
It can be positioned close to the sampling unit. In the housing is place for up to two
analytical channels that are controlled by one processor board. The Encal 3000 Process
Gas Chromatograph (PGC) transfers the core laboratory technique to process
conditions. Once the cap is removed from the base, almost all the internal components
are directly reachable.
The EnCal 3000 (measuring unit) includes the analytical components, the stream
selection and all the electronic components required for autonomous automated
operation.It can analyse up to 5 gas streams sequentiallyChanges in ambient
temperature have no significant influence on the peak retention times. The device
therefore does not need an expensive temperature-controlled environment.
Maintenance work is only required once per year. Routine calibration takes place
automatically at a time programmed by the user and leads to significantly lower
consumption of carrier and calibration gases. This reduces operating expenses
compared to conventional gas chromatographs.
