A pressure relief valve lets air pass in both directions and prevents that stress on panels and doors. Elebar valves act gradually through the oscillation of their membranes, driven by overpressure or vacuum, and are made entirely of nylon. To choose the model and number of valves, the required air flow is calculated with Q = (1000 \/ 273) \u00d7 V \u00d7 Dt (V: room volume in m\u00b3; Dt: maximum temperature change in 1 minute, in \u00b0C) and compared with each model&#8217;s flow for the permissible pressure difference (Dp, in mm of water column).<\/p>\n<h2>Technical specifications<\/h2>\n<ul>\n<li><strong>Reference:<\/strong> FI00847<\/li>\n<li>Model: Minielebar BT<\/li>\n<li>Use: low temperature (0 \u00b0C to -30 \u00b0C), with heater<\/li>\n<li>Horizontal installation<\/li>\n<li>Room volume: up to 20 m\u00b3<\/li>\n<li>Material: nylon<\/li>\n<\/ul>\n<h3>Approximate flow (l\/min) by Dp (mm H\u2082O)<\/h3>\n<table>\n<thead>\n<tr>\n<th>Dp<\/th>\n<th>2<\/th>\n<th>5<\/th>\n<th>7<\/th>\n<th>9<\/th>\n<th>12<\/th>\n<th>16<\/th>\n<th>20<\/th>\n<th>25<\/th>\n<th>33<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>Mini Elebar<\/td>\n<td>20<\/td>\n<td>76<\/td>\n<td>118<\/td>\n<td>150<\/td>\n<td>195<\/td>\n<td>250<\/td>\n<td>290<\/td>\n<td>360<\/td>\n<td>435<\/td>\n<\/tr>\n<tr>\n<td>Maxi Elebar<\/td>\n<td>250<\/td>\n<td>1400<\/td>\n<td>2000<\/td>\n<td>2600<\/td>\n<td>3400<\/td>\n<td>4300<\/td>\n<td>5200<\/td>\n<td>6200<\/td>\n<td>7600<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>Approximate values: please contact us if in doubt.<\/p>\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.
