  • cost effective device
  • almost maintenance free
  • certified flow performance curves

Функция и описание

The PROTEGO® E/H0 vent cap allows vessels which are not pressurized to vent. This device prevents rain and dirt from entering the vent line. The EH/0 vent cap is not flame transmission proof. It is often used in combination with detonation flame arresters, when those are used in vent lines, installed at a position which creates a long run up distance from the end of the vent line to prevent endurance burning. The PROTEGO® EH/0 vent cap will then be installed at the end of that vent line to prevent particles or rain from entering the line.

The vent cap PROTEGO® EH/0 main components are a housing (1), a weather hood (2) and a protection screen (3). The device is equipped with a fixed weather hood out of metal. The protection screen prevents particles or rain from entering the

Диаграммы пропускной способности

Диаграммы пропускной способности были определены с помощью калибрированной и сертифицированной объединением технического надзора (TÜV) проточной измерительной установки. Пропускная способность V. в м³/час определена воздухом при нормальных атмосферных условиях в соответствии с ISO 6358 (20°C, 1 бар). Преобразование для различных плотностей и температур см. главу 1: Технические основы
