A successful NIRON piping system installation for a Halas Hall turf conditioning project. Halas Hall (officially the PNC Center at Halas Hall) is a building complex in Lake Forest, Illinois, that serves as the headquarters of the Chicago Bears of the National Football League (NFL). Named after founder George Halas, the building hosts the team's front office, as well as indoor and outdoor practice facilities. Turf conditioning systems keep playing fields in peak condition, by keeping natural grass roots at optimal temperatures to extend the growing season. The NIRON range, particularly suitable for use in large buildings and for industrial installations ensures high mechanical resistance and duration, even at high temperatures and pressures. NIRON has become a recognized and trustworthy product range and has already been installed in various schools, colleges, hospitals, senior housing buildings, apartment buildings and industrial plants where safety and efficiency are of primary importance.
