Quintos System
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 must be flushed. This will ensure that a
possibly in the housing existing explosible atmosphere will be removed.
Depending
on the application and the existing atmosphere (gas or dust), at a
start-up of the cabinet QUINTOS
Exp will be flushed.
In
zone 1 and 21 is the control unit QUINTOC 1. It works with a
digital
valve and a proportional.
There are three standard temperature sensors.
It may also be used with another approved control device to Zone 1 or
21.
In zone 2 and 22 yopu can use the control unit QUINTOC 2. This
can work with a digital valve.
There are also three temperature sensors.

Start Up
It is
imperative that the documaentation 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 that before the initial start-up some key points
are reviewed to ensure a smooth operation for example, :
-- Are all cable glands locked
-- Is the cover of the 'pre-switch' closed
-- Is the cover of the control unit mounted
-- Is the key for the bypass switch off
-- Is the pressure gauge withina value of 2.5 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 pre-setted
flush time passes by, monitored by the control unit.
After the flushing phase, the 'pre-switch added and automatically
switches the power supply.
Inside the QUINTOS Exp cabinet is a transitional pressure and
temperature settings can be found via the control unit.
