servingthe international oil& gas industry
ITALIAN TECHNOLOGY
HEATING, VENTILATION & AIR CONDITIONING UNITS (HVAC)
The company is an active manufacturer of Heating, Ventilation &
Air Conditioning units (HVAC) for installation in hazardous areas
(refi neries, oil wells, off-shore platforms, etc.) dealing effectively
with the most severe environmental conditions.
More than ten years’ experience in the fi eld of system integration
with the production of process analyzer shelters, has allowed us
to create high quality and top performing HVAC units.
Our wide range of HVAC systems allows us to meet the demands
and needs of our customers.
ATEX certifi cation of these systems makes our company a
landmark for end users, top engineering companies and main
contractors.
AUTOMATIC SAMPLING
The company is an international leader in designing and
manufacturing automatic sampling systems for crude oil and
refi ned products.
Automatic Sampling is an increasingly worthy activity when oil
custody transfer takes place.
The rising costs of raw materials, processing and disposal of
pollutants have made a representative sample strategic because
it represents the entire batch of oil in transit.
Years of experience in the fi eld and unparalleled professionalism
guarantee immediate returns on investments, as sampling
becomes a means for cutting costs signifi cantly over time.
Today, Autocontrol Technologies has supplied its customers with
automatic sampling units throughout the world in oil terminals,
production wells, off-shore platforms, tankers, refi neries and
metering skids.
The company is also a permanent member of the main international
organisations (ISO, API) that regulate this strategic matter.
PROCESS CONTROL SYSTEMS INTEGRATION
The company is largely involved in the system integration and
process engineering for Oil & Gas applications, which includes the
design and manufacturing of:
- sample conditioning systems, recovery systems, calibration
systems for process analyzers.
- analyzer shelters and cabinets for safe and hazardous areas
designed to integrate process analyzers and control automations.
- on-line analyzers’ automation systems for continuous monitoring
of chemical/physical properties of process and environmental
controls.
Autocontrol Technologies has supplied hundreds of systems to
the main oil & gas companies worldwide.
Autocontrol Technologies was established in 1994 by its
managing director, Roberto Scatizzi, in order to offer fresh
solutions in the on-line instrumentation, process measurements
and control automation fi elds, assisting the customer from
design to installation with complete turn-key services.
The company’s core business is engineering, construction and
installation of high technology process instruments for the oil,
petrochemical, chemical and power industries.
The company is ISO 9001:2008 certifi ed and ATEX notifi ed for
applications in hazardous areas.
Autocontrol Technologies is organized in three main divisions:

There are also the following non-electrical components (risks
analysis already carried out):
• Fans;
• Air Refrigerant gas heat exchangers, fi nned battery type, with
copper tubing and aluminium fi ns;
• Cooling circuit made of copper welded with precious alloy,
completed with: lamination capillary tube, mechanical dehydra-
tation fi lter, brass valves, pressure and temperature control de-
vices.
The HVAC units will be equipped with a Control Box, Power
Box/es and a Box for the intrinsically safe barriers and they will
be fully controlled by a PLC (Programmable Logic Control) and
the alarms will be sent to Control Room by free contact relay.
All the lamps and the control switches for the HVAC units status
control / monitoring will be installed in front of the control box.
AUTOCONTROL TECHNOLOGIES, in these last years, has
developed a Graphic Controller system for the HVAC units
status control / monitoring.
This system is composed of a graphic panel for the HVAC
monitoring (alarms and status of the system) and a keyboard
suitable for the control (Temperature setting).
This system can be protected by password.
All the HVAC units can be built also for Safe Areas.
