Our equipment is designed in strict compliance with the applicable local and major international safety standards and each part is accurately tested to ensure top performance and full reliability.
TECHNOLOGICAL PROGRESS Advanced hardware design is the bedrock of our success with an intensive use of computer-based process automation systems right from the second half of the eighties, even in applicative fields which were considered “too poor” for computer science application. POLA can now boast thousands of processors installed in agricultural industries and homes throughout the world, working in different climate conditions.		CUSTOMER SUPPORT The range of products includes a few hundreds of standard models destined to various fields of process automation. Customized systems can also be committed to our research team that is able to develop specific high-tech products within a space of time as short as a week.
ACCOUNTING A data processing centre (EDP) linked in real time to internal user video terminals provides immediate handling of orders to ensure prompt deliveries.
