MRX Condensing gas air curtain

Comfort and cost-effective ”Premium” solution nearby doors for industrial buildings:

  • Vertical mounting
  • Hot air jet (less than 40 seconds)
  • Recommended installation height: 3 to 6 metres

Avantages

  • Laminar air jet (homogeneous blowing)
  • Gas savings between 15% and 45% 
  • Record combustion efficiency of 107%
  • Continuous modulation from 30% to 100%
  • Ultra-fast warm-up time
  • Absolute safety (no flames or combustion gases in the air flow)
  • Corrosion-resistant components 
  • No risk of polluting the reheated air because of separation of the combustion part/air circuit
  • Shut-down on full power tolerated by damp combustion chamber and hot water heat exchanger
