The advantages of the ZASE series

  • Superior thermal insulation capacity, constant and stable on the whole surface of the panel.

  • Extremely elevate structural rigidity of the units, suitable also for applications at the limits, such as industrial applications with continuous elevate differential operating pressures and use of remarkably heavy components, such as heat exchangers with pipes/fins in iron or stainless steel etc.

  • Superior sound absorbing capacity.

  • Total absence of thermal bridges since all the profiles and supports in aluminium have been eliminated, homes of dangerous condensations specially in applications at the limit, such as in outdoor units, or units serving low temperature technological cycles.

  • Total absence of protruding screws.

  • Maximum pneumatic tightness in the most different operating conditions.

  • Maximum performance levels obtained in all classes of the Eurovent Certification Program.

The base frame

The base frame constitutes a continuous support to the units under all sides and  allowing to unload the weight on a larger surface reducing the load on the structure on which our units are placed. The base frame is manufactured by coupling a galvanised cold-rolled metal profile, 30/10 thickness welded at the corners and with a height of 180mm.

Condensate drain pans

Condensate drain pans exclusively in stainless steel material: AISI 304 stainless steel with 15/10mm thickness, with very elevate mechanical performances. Also the support frames for cooling coils and humidification systems and, in general, all the wet surfaces inside the unit, are manufactured in AISI 304 stainless steel with 10/10 mm. Each condensate drain pan is equipped with one or more discharge points complete with pipe, also manufactured in stainless steel.

Type of panels

  • Pre-plasticized galvanised external / galvanised internal: the external sheet is constituted by a plasticized galvanized sheet, the internal one by a simple galvanized sheet

  • Prepainted external / galvanised internal: the external sheet is constituted by a prepainted metal sheet, the internal one by a simple galvanised sheet

  • Stainless steel external / stainless steel internal: both sheets are in AISI 304 stainless steel at a very elevate mechanical resistance and absolute inalterability to external agents.

Protection roof

All our units manufactured for outdoors installation, or in general which should resist different weather conditions, may be equipped with a protection canopy in galvanised pre-plasticized steel, aluminium or AISI 304 stainless steel.
