There are three types of heat exchangers including parallel-flow, cross-flow and shell-and-tube types, but there are many more brands including fabsco and harpin. These machines are typically used to transfer heat between solid surfaces and fluids, between fluids and other fluids using thermal contact and different temperatures. They have an important job and regular maintenance is important to keep them working optimally. The shell portion of fabsco, harpin and other brands of heat exchangers can last more than 40 years with proper maintenance. Read below to see simple maintenance tips that can extend the life of not only the shell, but the entire unit.
Schedules
The purpose of having regular scheduled maintenance ensures that your heat exchanger continues to work as it is designed to do. The heat exchanger design relies on regular scheduled maintenance in order to work. Regular interval cleanings should be performed, and these cleanings should be scheduled about every six months. Visual exams should be performed along with regular checks on the gauges and the pressure. Ensure all pipes visually appear good and inspect the pumps of your shell and tube heat exchanger. Routine maintenance eliminates larger problems which cause downtime to repair.
Testing
You want to periodically ensure that the pressure on your unit is at the proper level. Also check to ensure that the heat transfer fluid is moving properly. Chemicals can slowly degrade heat transfer coils, so routine checks can ensure that they are working properly. Without proper maintenance, not only can the coils and tubes degrade and break down, but the risk of fire increases. Routine testing ensures everything within your machine is doing what it should be doing.
Gas
Gas mains should be checked routinely to make sure they are properly working and there are no leaks. Check all exchangers and burners to ensure the are clean. Look, listen and inspect the vent to ensure it is properly working and ensure there is nothing obstructing the discharge paths of your unit. Inspect all connections to ensure they are tight and check any electrical connections that run to the unit. Check all pilot lights sensors to make sure they are clean and operate as they should.
Remember these tips and use them to keep your unit working properly. Regular maintenance and checks are important for the life of your equipment and the safety of those operating it. Remember to follow manufacturers instructions, as they can be specific for your exact unit, meaning fabsco unit maintenance may differ form harpin unit maintenance.
