Heat Transfer BrazedPlate Heat Exchangers Installation, Operation and Maintenance Manual
Installation of ITT Brazed Plate Heat Exchangers 1. Upon receipt of the exchanger, inspect for shipping damage, especially to the connections. If damage is extensive, notify the carrier immediately. Finally, check the heat exchanger against proper drawings and spec sheets to make sure everything is as expected. wn e 2. n both fluids at the same time. Before piping up, inspect all openings in the heat exchanger for foreign material. Remove all plugs n hot fluid then cold fluid.

Maintenance 1. 2. Clean exchangers subject to fouling (scale, sludge deposits, etc.) periodically, depending on specific conditions. A sludge or scale coating on the plates can reduce effectiveness. A marked increase in pressure drop and/or reduction in performance usually indicates cleaning is necessary. As suggested under “Operation”, the use of a strainer is recommended if the fluid quality is poor (extensive dirt, debris, and contaminants).
