Installation Figure 11: Units on the same level Limitations:The distance between the two units must not exceed 60 m in reality or the equivalent of 90 m taking into account pressure drops. The height of the liquid line in relation to the unit base must be less than 5 m. It is recommended to place a trap on the discharge line at the oil separator outlet, if this discharge line is horizontal for a distance greater than 5 m, at a height greater than the connection to the oil separators. - Page 18 Installation Figure 13: RTCA (or other manufacturer's condenser) below the RTUB Limitations:The distance between the two units must not exceed 60 m in reality or the equivalent of 90 m taking into account pressure drops.
