Move vertically downwards and select a suitable model and orifice size. • The selected capacity should be equal to or higher than the condensate load after including a safety factor of 2 to 3. Oversizing is not recommended. • Example - Operating conditions = I) Inlet press. 4 bar(g) II) Back press. 1 bar(g) III) Condensate load 480 kg/hr. IV) Safety factor 2. Model Selected: PT25-20 • Orifice size : 6.4mm • Capacity 1075 kg/hr @ a diff. press. of 3 bar.
