  • Page 8 NTRODUCTION TORE URTAIN 1.3.3 MAT air curtain operation General The air curtain unit creates a constant, vertical airflow across the full width of the door opening. This acts as a barrier between indoor climates in the cold store and front hall. This minimises the exchange of heat and humidity.
  • Page 9 MAT M ANUAL NTRODUCTION Purpose of corridor Climate partitioning – door closed The corridor is essential in order for the MAT air curtain to work properly. When the cold store door is closed (see figure above), this acts as a partition between the cold store and front hall. When the cold store door is open, the MAT air curtain estab- lishes an effective barrier between these climates (see figure below).
