Looking for an effective way to prevent heat loss? Discover our solutions!

We’d like to introduce our air curtains with electric heaters:

 

  • GUARD Air Curtain – a high-performance curtain with a 3-phase heater (400V), ideal for areas where maximum efficiency is a must. Available in 1-meter, 1.5-meter, and 2-meter lengths.
  • GUARD ONE Air Curtain – a practical solution with a single-phase heater (230V), perfect for smaller spaces where you need something compact yet powerful. GUARD ONE comes in a 1-meter version, but if you're covering a 2-meter-wide entrance, simply install two!

Both models offer:

  • Reliable protection for entrance areas
  • Energy savings
  • Long-lasting performance
  • A sleek, modern design

Get in touch to find the perfect solution for your space!
