Product applications
Air curtains function as an invisible barrier, effectively preventing the ingress of external air and curbing the egress of conditioned indoor air. This safeguards the internal temperatures of your dining area, bar, or cold storage, reducing the strain on your HVAC system. Consequently, this leads to decreased maintenance costs and avoids unnecessary energy expenses. Employing an air curtain as a thermal barrier ensures that the energy expended to heat or cool your establishment is utilized efficiently, not wasted. This approach significantly lowers overall energy consumption, diminishes your carbon footprint, and reduces operational costs. Moreover, it maintains a consistent temperature by counteracting both hot and cold air infiltration.
