A few pictures of recently mounted freezing doors in the USA. The doors in the picture are the Salco VH-1414 vertical. Especially the speed of this door is impressive: 0.8 m / sec, for a door of 3400 * 3000 (W * H)! These freezing doors are available with or without freezing sill and distinguish themselves not only by their speed but also by their long service life and low Total Cost of Ownership (TCO). These doors are also available as a do-it-yourself kit, which saves on expensive freight costs, especially when it comes to distant jobs in the USA or Australia. For the USA market, our doors are UL certified.
