The KEN IWD 521 XLS Washer-Disinfector, has been specially developed for CSSDs, as well as in Surgical and Anesthetic wards where there is a requirement for capacity, flexibility and full process documentation.

The computer controlled monitored washing process and the rotating washing heads ensure a high quality and uniform result. Every cycle finishes with a disinfection of the nozzles, wash heads, combitank and pump.

The machine is very narrow at 736mm wide, and is able to process 18 surgical instrument trays – an equivalent capacity competitor machine is 1100mm wide.

KEN machines offer the market’s highest instrument tray throughput for their size. This is especially useful for existing spaces, where it is not possible to add more space.

It is available as a slightly smaller capacity model, the IWD 521 and the newer IQ5.

High efficiency

Smart computer and sensor controlled wash cycles combined with high quality components mean high energy savings.

Tested to have consistently beaten the competition in both electrical and water use efficiency, KEN washer-disinfectors use no energy when not in use and will drastically cut energy bills, to help reduce your carbon footprint.

Fully programmable

KEN machines are able to be programmed to your exacting requirements.

Useful for reducing operator error and ensuring consistent results every-time; full programmability is available as standard. Multiple programmes can be stored and every aspect of the wash cycle is able to be configured to match your requirements.

Reliable sanitizing

The inclusion of a combination heating tank in KEN machines, ensures reliable sanitizing results.

Traditionally, any variation in line temperature means competing products become unusable at peak hospital utilization. Regardless of line temperature, KEN machines are able to control temperature internally and ensure always-on availability.

Remote monitoring

Network monitoring of performance, ties your institutions infrastructure together.

Using our optional remote monitoring service, KEN washer-disinfectors performance, faults or maintenance notifications can be diagnosed remotely to prevent equipment downtime and to improve reliability.

The pass-through design ensures the effective separation of an unclean and a clean side, which reduces the risk of hospital infections.

This versatile machine can wash up to six levels. Various accessories and racking combinations are available to suit your requirements.

A optional stainless steel trolley is available, these are flexible enough to work with your unique requirements and help to reduce operator strain.
