Effective Thermal Disinfection at POU

By using the readily available system temperature hot water supply (>60C), the patented ILTDU, In-Line Thermal Disinfection Unit, from Horne Engineering facilitates the only effective thermal disinfection of showers, taps, TMVs, their associated pipe-work feeds, ancillary fittings, mixed water deadleg and terminal outlet fitting. In conjunction with high velocity flushing, which shears excess biofilm from internal pipework surfaces (and represents 95% of the water system’s total bio-load) thus improving water quality, regular operation of the ILTDU further aids the risk-management of retrograde pathogens, e.g. opportunistic Pseudomonas Aeruginosa, Non-Tuberculous Mycobacteria and others.
