About us

The history of our company dates back to the post-war years – 1948 and connects with the development and industrialisation of south-eastern Poland. The initial period of the company’s activity was related to the organisation of enterprises in Poland in the 1950s within the structures of the legal entity of the Unification of INSTAL Enterprises and state-owned property. The main task of the newly established enterprise was to carry out installations in built industrial plants and municipal facilities. The production of own products was also developed.

In later years, after economic reforms in Poland, the company became a separate economic entity in the form of a joint-stock company with 100% ownership of the State Treasury.

In 2002, a limited liability company was registered under the name Instal Rzeszów Zakład Zbiorników Sp. z o.o., which in 2010 acquired from the State Treasury part of the organised assets of Instal Rzeszów SA, while changing the name of the new entity to Instal Rzeszów Sp. z o.o. From November 24, 2016, the new entity Zakład Zbiorników Instal Rzeszów Sp. z o.o. together with the acquisition of fixed assets and some employees, resources and intangible rights, it operates under the trademark INSTAL RZESZÓW recognized in Poland and in Europe.

The company’s main activity is the production of steel technological equipment for the storage of powdery substances, liquids and gases in the conditions of overpressure, underpressure and atmospheric pressure. The devices are necessary in technological processes and installations in all areas of the economy, e. g. in the chemical, petrochemical (refinery), gas, energy and metallurgy, food, medical and construction industries. The company participates in the implementation of many investments by supplying a wide range of specialised technological devices to the market. The production of the Company in a significant part, due to the legal regulations of the EU market and the requirements of Polish legislation, is certified by independent bodies notified under Directives 2009/105 / EC, 94/9 / EC, 97/23 / EC, 2006/42 / EC, 89/106 / EEC on the EU market and the Polish bureau of Technical Inspection, in case of other statutory requirements in Polish market regarding the storage of corrosive, poisonous, flammable and explosive liquids.

The company’s products, designed and proven for many years, are covered by the Catalog of Own Products of Instal Rzeszów issued every year since 1975.
