Cold room walls are subject to pressure differences between inside and outside: when evaporator defrosting starts, when a lot of goods are loaded, with long door openings or with changes in atmospheric pressure. A pressure relief valve lets air pass in both directions and prevents that stress on panels and doors.<\/p>\n<h2>Technical specifications<\/h2>\n<ul>\n<li><strong>Reference:<\/strong> FI00275<\/li>\n<li>Model: Evo-Maxielebar BT R20912<\/li>\n<li>Installation: wall<\/li>\n<li>Temperature: 0 \u00b0C to -30 \u00b0C (BT version)<\/li>\n<li>Power supply: 220\/240 V<\/li>\n<li>Heater power: 40 W<\/li>\n<li>Mounting and wiring from inside or outside the room<\/li>\n<li>Special seal on the flaps for better tightness<\/li>\n<\/ul>\n<h2>Applications<\/h2>\n<p>Doors and installations of <a href=\"https:\/\/www.tiendabernad.com\/en\/categoria-producto\/cold-storage\/\">cold rooms<\/a> in the food industry: as a replacement or to fit a new door.
