The MA-I / MA-IU can be installed in pipe headers, elbows, tees and similar fittings. The main line suffers no appreciable pressure loss due to its restriction. No special supports are required for installation. The higher the main fluid velocity the better the desuperheating, since, with higher velocity, a shorter distance is required to achieve mixing. The temperature sensing element should be located approximately 40' (12m) downstream from the desuperheater.
