Quintos System (new approach)
The
explosion
protection by pressurized system is realized by using the non-explosion
devices in a overpressurized housing (p ex-housing). This housing by a
permanent pressure with air or inert gas keeps away a potential
explosive atmosphere. Depending on the application and
existing explosion protection zone, before using the devices or
controlsystems the housing be released by a das detection(mobile or stationary). This will ensure that is
not a
possibly explosible atmosphere in the housing existing .
Depending
on the application and the existing atmosphere (gas or dust), at a
start-up of the cabinet QUINTOS
Exp will released by gas measurement(should be on site).
In
all
zones is the control unit QPU used. It works with a
digital
valve or a proportional to compensate the leakage of the panel or enclosure.

Start Up
It is
imperative that the documentation of the control unit is added to the
Quintos test report
With these two protocols the test procedure and the individual setting
of the parameters are clear proved .
It is important before the initial start-up that some key points
are reviewed to ensure a smooth operation for example, :
-- Are all cable glands locked
-- Is a gas detection done before start up
-- Is the cover of the control unit mounted
-- Is the key for the bypass switch off
-- Is the pressure gauge withina value of 2 bar
Are all these checked, the doors closed and the control cabinet can be
filled with
compressed air or inert (not explosible, such as nitrogen) gas.
The built-in valve opens and the pressure increases, the Quintex patented main
contactor (installed within the cabinet (no expensive flameproof enclosure
ist needed) switch on and automatically
switches the power supply.
