PROCOM 2 or CYCLIC 2020 regulation - SEC 7HC air treatment type
2.4 Air treatment system
The air treatment system is composed of:
• A cyclone/filter fitted with an electronic air vent valve with an alarm contact in case
of failure,
• A micronic filter, then a submicronic filter both equipped with condensate drain,
• An adsorption dryer with 3 levels of air treatment:
Molecular sieve to remove CO2 and humidity,
Activated carbon to remove oil vapours and odours,
Hopcalite to remove CO.
• an activated carbon filter for odour elimination.
Each air treatment system is designed to support the flow rate of one compressor.
2.5 Receiver
Service conditions: The service conditions are specified on the receiver identification
plate.
The operating pressure should never exceed the service pressure.
The following minimum and maximum temperatures shall be complied with:
0 to 600 liters:
Tmin = -10°C
Tmax = 60°C
These temperature values are given as a function of the capacity and only
apply to the pressure receivers used with our HOSPITAIR products.
Purpose of use: These are single pressure devices designed to contain air or nitrogen.
Installation and maintenance:
The receiver must be installed in neutral, normal and current atmosphere and in places
which are not likely to involve a rise in temperature of the device exceeding the
temperature of service; it must be connected to ground. Access for check must be easy.
Incidents are always possible (exhaust of valve, leakage on drain or valve, etc.) so it's
better to avoid the installation of a device in an attended site, or near fragile devices.
To check its interior state, the receiver must be visited regularly and according to the
regulations in force in the country where it is installed.
A depth control must be practiced regularly with adequate means (ultrasound,
magnetic...).
Fixing and fastening of receivers must be made while taking care to avoid all forced and
tensions and to damp out all vibrations, even non-visible.
The base of the receiver will have to support the weight of the receiver, including in
situation of tests.
In performing inspections, visits and periodical tests, we remind users to comply with
the legislation in force where the tanks are in use in their country.
The equipment must not be modified without the manufacturer's prior approval.
519015-15
HOSPITAIR CABIN (MV) – 11 & 15 bar
600 to 2000 liters:
Tmin = 0°C
Tmax = 50°C
In complement of the indications hereafter, refer to the instruction manual
provided with each receiver.
The receivers and their accessories must be protected from freezing and the fire.
Use adequate handling and lifting system and take care not to damage the receiver or
its components.
Before proceeding to the inspection and/or maintenance operations on the receiver
and its components, make sure that this one is completely drained (internal pressure
equal to the atmospheric pressure).
Not to carry out a welding or modifications (drilling, heating with a flame,) on the parts
under pressure of the receiver.
The connection of the receiver with the installation must be carried out with flexible
connections in order to avoid all vibrations.
Take care that the receiver is always provided with its security accessories and its
inspecting devices.
In the event of damage of the device, check by calling upon a specialist, that the
receiver can be used in full safety.
2.6 Electrical architecture
Each screw compressor has a specific electrical subsystem; we have a regulation unit
fitted with the PROCOM-2 or CYCLIC 2020.
Check that the button AUTO/CONTINU in the front side of the regulation board is in the
AUTO position
NB: the button on the CONTINU position allows compressors to operate in forced
running.
This functionality allows troubleshooting procedure or test on the compressor.
The HOSPITAIR C2 are supplied by two electrical sources named X and Y to ensure the
continuity of the air source in case of failure of one power supply.

CHOICE OF LOCATION
The unit must be located in a clean, non-humid, non-saline, dustless environment.
This location must be adequately ventilated and the ambient temperature
must be between +5°C and +40°C.
The installer has overall responsibility of the product environment requirements.
Means to fight against fire, to protect air units against shocks, floods, earthquakes and
corrosion must be installed by the installer.
All constructions, whether of buildings, civil engineering infrastructures or earthworks,
are the responsibility of the operator and/or the installer.
External environmental constraints must be managed (snow, wind, rain...).
