Once there’s moisture in the system, acid can form, seriously damaging the expensive, more glamorous components. There-fore, it’s important to choose the correct filter-drier for the application, and then size it and install it correctly, if you want to head off problems down the road.
A filter-drier may also be placed in the suction line, but it’s important to note that a suction line drier is really designed to be put on as a cleanup tool and then removed once the system is clean. In today’s hectic world, contractors often don’t take the time to come back and take out that drier when the cleanup is finished. If the suction line drier is left in long enough, it may become fully saturated if there’s a lot of moisture present. Then the drier begins to disintegrate, resulting in abrasive materials running through a system.
