A\u00a0<span style=\"text-decoration: underline;\">flexible air buffer<\/span>, also known as a &#8216;buffer lung&#8217;, is installed to compensate these small pressure differences. The excess air in the cold room is captured in it (at overpressure) and, if necessary (at underpressure), returned to the cold room. This prevents the undesired penetration of oxygen-rich air. Using a buffer lung with a sufficient capacity can compensate for a big part these pressure variations.<\/p>\n<p>However, there are circumstances that the buffer lung is insufficient to relief the cold room from its under- or overpressure. When the cold room is not relieved of this excess pressure difference, the panels of a cold room are literally pushed out (in the case of overpressure), or sucked inside (during underpressure), resulting in a lot of damage. Cold rooms should be fitted with over- and underpressure valves to protect against excessive pressure differences. The\u00a0<span style=\"text-decoration: underline;\">Besseling pressure reliefs<\/span>\u00a0have a diameter of 160 mm, which means that more air can be transported compared to a 125 or 110 mm overpressure valve. In short: better protection.<\/p>\n<p>To give you an idea of the difference:<br \/>\n\u00d8 160 mm has a surface of 201 cm\u00b2<br \/>\n\u00d8 125 mm has a surface of 123 cm\u00b2<br \/>\n\u00d8 110 mm has a surface of 96 cm\u00b2<\/p>\n<p>This means that a \u00d8 110 mm pressure valve has\u00a0<span style=\"text-decoration: underline;\">less that half<\/span>\u00a0of the compensation capacity compared to a \u00d8 160 mm valve.
