ITALIAN TECHNOLOGY

serving the international oil & gas industry 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 fields, 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 certified and ATEX notified for applications in hazardous areas. Autocontrol Technologies is organized in three main divisions: HEATING, VENTILATION & AIR CONDITIONING UNITS (HVAC) The company is an active manufacturer of Heating, Ventilation & Air Conditioning units (HVAC) for installation in hazardous areas (refineries, oil wells, off-shore platforms, etc.) dealing effectively with the most severe environmental conditions. More than ten years’ experience in the field 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 certification 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 refined 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 field and unparalleled professionalism guarantee immediate returns on investments, as sampling becomes a means for cutting costs significantly 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, refineries 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. 2

Autocontrol Technologies has supplied hundreds of systems to the main oil & gas companies worldwide.

There are also the following non-electrical components (risks analysis already carried out): • Fans; • Air Refrigerant gas heat exchangers, finned battery type, with copper tubing and aluminium fins; • Cooling circuit made of copper welded with precious alloy, completed with: lamination capillary tube, mechanical dehydratation filter, brass valves, pressure and temperature control devices. 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.
