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.
