Supply of industrial gases, liquid gases and specialty gas mixtures and related services

Description

The Joint Research Centre at Ispra and Petten sites runs several laboratory and technical facilities. Some of these facilities need to use industrial gases, liquid gases and specialty gas mixtures at different pressures and flow rates, for scientific or technical activities. The subject of this procurement procedure therefore includes the supply of industrial gases, pure gases, liquid gases and gas mixtures. It also includes the distribution of gases to users by means of a service provided by the contractor. The object of the framework contract is the ‘Supply of industrial gases and specialty gas mixtures and related services at the Joint Research Centre — Ispra site, Italy and Petten site, Netherlands’. In the JRC Ispra site, in Italy, there are several scientific laboratories and support services which need to use various technical gases and liquid gases for the prosecution of their activities. A network of pipes with dedicated control systems delivers the gas to the scientific/technical equipment. The Institute for Energy and Transport of the Joint Research Centre (JRC-IET) runs several laboratory facilities that have different scopes and serve different purposes at different locations within the campus of the JRC-IET in Petten, Netherlands. These facilities have extensive gas tube/pipe networks (with dimensions in imperial and metric units) including (automated) controls and auxiliary devices (i.e., suction huts, vent and exhaust pipes, etc.) and use various technical gases at different pressures and flow rates; some of these gases are categorised as harmful (asphyxiate, toxic and/or flammable) and liquid gases. The type of gases already used in the JRC Ispra and JRC Petten sites include standard gases: argon, zero air, helium, hydrogen, nitrogen, etc., special mixtures of different gases in various concentrations (ranging from several VPPM up to several vol%), and liquid gases as liquid nitrogen and helium, and which are the subject of the current call. The types of gases are divided into 3 categories: — industrial, pure and technical gases in cylinders and packs and correlated services, — liquid gases (nitrogen and helium) and correlated services, — certified gas mixtures in cylinders and packs and correlated services. All the gases delivered must be certified and, in particular cases, primary certified mixtures (offering the highest accuracy possible even in range starting from a few ppm, e.g., 1 % to 2 % accuracy at concentration below 5 ppm) for calibration purposes will be requested.
