S&P Sistemas de Ventilación is the Spanish operation of the Soler & Palau ventilation group, based at Parets del Vallès outside Barcelona, and sits on TECNIFUEGO’s smoke-control committee. Its fire-protection line covers jet-fan impulse ventilation for car parks and tunnels, stairwell and vestibule pressurisation equipment, and fire dampers. The TJHT and TJHU jet fan page states that the fan is approved to EN 12101-3 and publishes CPR certificate numbers 0370-CPD-0672 and 0370-CPD-1481 for the 400 °C two-hour rating and 0370-CPD-0673 and 0370-CPD-1422 for 300 °C, the 0370 prefix identifying the notified body. Reference smoke-control installations include the Spotify Camp Nou and the Santiago Bernabéu.
