Overview
What it does.
The AWD655 is a complete line of instrument washer disinfectors designed to meet hygiene standard EN ISO 15883-1/2 and 5, developed for hospital departments, dental clinics, surgical departments, and central sterilization services (CSSD). The line spans four chamber capacities — 65, 165, 265, and 430 liters — offered in counter-top, under-the-counter, and freestanding column configurations, with manual, pass-through manual, automatic sliding, and pass-through automatic door options. All models feature a wash chamber built in AISI 316L stainless steel, forced-air drying with HEPA H14 filtration (except no-drying variants), and a touch-pad or touch-screen control panel with alarm-check diagnostics and up to 40 customizable washing programs. The plumbing system isolates the potable water pipeline per EN 1717, and models can be configured on request with boilers, hybrid electric-steam heating, water softening, conductivity monitoring, and automatic trolley recognition, supporting the wide variety of instruments found in modern healthcare facilities, including tubular and hollow instruments.
