Shell and tube exchanger
Shell and tube heat exchangers exchange thermal energy from one fluid to another. Because it is characterised by low pressure loss, it is well-suited to air conditioning systems.
Solenoid valves are broadly used for controlling heat or cooling with ON/OFF consumers. An electrical current is turned into a magnetic field, which opens or closes the valve mechanically.
Sources of legionella in commercial buildings other than water systems
Microbacterial growth is not only a problem in hot and cold water systems and cooling towers but also in many other applications in commercial buildings such as water fountains, spas, swimming pools and fruit and vegetable moisturising systems.
