Danfoss Turbocor VTT : Compresseur sans huile avec plage de puissances pouvant atteindre 350 tonnes/1 200 kW

  • Turbocor VTT series  - Danfoss
  • Des performances de débit toujours plus élevées dans une conception toujours plus réduite

    Voici la nouvelle gamme VTT de compresseurs Turbocor de Danfoss, fer de lance technologique des compresseurs sans huile, à vitesse variable et équipés de paliers magnétiques. Basés sur les technologies qui ont fait le succès de la gamme TT de compresseurs Turbocor de Danfoss, les compresseurs VTT (Variable Twin Turbo, biturbo variable) sont dotés de la technologie IntraFlow™ et offrent les meilleures performances à charge partielle et totale sur marché, ainsi que des caractéristiques de débit inégalées. La gamme VTT augmente par ailleurs la plage de puissance des compresseurs centrifuges précédemment proposés par Danfoss jusqu’à 350 tonnes/1 230 kW.
    Les compresseurs VTT fonctionnent au R134a.

    Technologie IntraFlow™ exclusive
    La nouvelle technologie IntraFlow™ (brevet en attente) permet aux compresseurs de la gamme VTT d’éliminer les coûts et la complexité liés aux aubes de guidage d’entrée ou aux diffuseurs à géométrie variable et simplifie aussi la régulation de la puissance, étend la plage de fonctionnement stable et accroît les performances des compresseurs centrifuges.

    La technologie IntraFlow™ redirige une partie du flux depuis la volute de sortie vers l’entrée du diffuseur du premier étage à l’aide de plusieurs gicleurs. Cette injection de fluide dans le diffuseur du premier étage apporte une régulation de l’incidence aérodynamique et confère aux compresseurs VTT la plus grande plage de fonctionnement stable parmi tous les compresseurs centrifuges.

    • Meilleures performances du marché à charges partielle et totale
    • Meilleur débit
    • Extension de la plage de fonctionnement stable
    • Élimine le recours à des aubes de guidage d’entée ou à tout autre diffuseur mécanique
    • Les nouveaux compresseurs VTT sont conçus pour permettre aux constructeurs de se conformer aux exigences drastiques attendues dans la norme ASHRAE 90.1-2015 Path A ou Path B relative aux refroidisseurs.

    Applications et données
    Les compresseurs Turbocor VTT de Danfoss sont conçus pour répondre aux exigences opérationnelles des applications refroidies par eau ou par évaporation et présentent des plages de puissances nominales comprises entre 200 et 350 tonnes (700 à 1 230 kW).  

    De par leurs capacités de réduction de puissance, les compresseurs de la gamme VTT sont idéaux pour les bâtiments fonctionnant 24 heures sur 24, 7 jours sur 7, tels que les centres de données et les hôpitaux.

    La gamme VTT sera disponible pour les applications dont la tension est comprise entre 380 et 575 volts et porteront les marquages ETL et CE PED.
