Visionstar WS-YDB

Computer Controlled Course

The sterilising course is described as automatically controlled by computer and easy to operate, so a cycle runs without the operator managing each stage of it.

Printer Fitted

A printer is fitted to the unit, producing a record of a cycle from the machine itself rather than from a figure transcribed by whoever happened to be present.

Separate Sterilising and Drying Timers

Sterilising time is 0 to 99 minutes and drying time is separately 0 to 99 minutes, listed as two distinct rows rather than as one shared figure across both stages.

Three Chamber Capacities

Volumes of 150L, 200L and 280L are offered, at 440 by 1000mm, 515 by 1000mm and 600 by 1000mm respectively across the three models in this range.

Drying Function

A drying function is fitted and described as suitable for dressing drying, which is what allows wrapped and textile loads to leave the chamber dry.

Door Pressure Interlock

The door opening mechanism cannot be operated until chamber pressure has reduced to 0.027 MPa, and the unit cannot be started if the door is not closed well.

Safety Valve With Steam Recovery

The safety valve opens automatically when inner pressure exceeds 0.24 MPa, with the steam exhausting back into the water tank rather than into the department.

Low Water Protection

Power is cut off automatically, the water is cut off and an alarm sounds when the machine lacks water, so a dry run is prevented and not merely signalled to the operator.

Departments Keeping Cycle Records

A printer producing a record of each cycle genuinely changes what a department can demonstrate. Where a written procedure requires evidence that the cycles reached their intended conditions, a printed record from the machine is considerably stronger than a note taken from a gauge, and it removes the transcription step where errors most commonly enter a record of the work in the first place.

Dressing and Textile Processing

Separate sterilising and drying timers matter most of all for textile loads. Dressings frequently need a longer drying stage than the sterilising stage requires, and a machine with one shared timer forces a compromise between the two of them. Timing them independently means a pack can be dried properly without the sterilising stage being extended unnecessarily in order to suit it.

Hospital Sterilising Departments

A 280L chamber processes in a single cycle what a bench unit would take an entire session to work through. For a central decontamination unit serving several clinics or a number of theatres, capacity at this scale combined with computer control and printed records is what allows instrument turnaround to be both fast enough and documented well enough for the clinical work that it actually supports.

Laboratories and Veterinary Hospitals

Media, glassware, drapes and bulk consumables all need a chamber sized for volume, and not merely for trays. A horizontal cylindrical vessel a metre deep accepts the loading arrangements no bench chamber can take, and the protections address the practical reality that a machine of this size runs repeatedly while staff attend to other things entirely, elsewhere in the department.

The Machine Documents Itself

Computer control and a fitted printer together mean the equipment supports the paperwork as well as the process. A department can show what each cycle actually did without anyone writing anything down, which removes both the labour and the transcription error along with it. Where decontamination is inspected, a printed record produced by the machine is worth considerably more than even the most carefully kept logbook.

Drying Timed on Its Own Terms

Two independent 0 to 99 minute timers, one for sterilising and one for the drying, is a more useful arrangement than a single shared figure. Dressings and textile loads often need longer drying than sterilising, and separating the two lets each stage be set for what it actually requires rather than one being stretched or cut short to accommodate the other stage of the cycle.

Protections That Act Rather Than Warn

Each named protection intervenes rather than merely signalling. The door cannot be opened until pressure has fallen, the machine cannot start with the door improperly closed, the safety valve opens on over pressure with steam routed back to the tank, and power is cut on low water. On a vessel holding this much energy, protections that physically prevent the wrong thing happening are what make the equipment reasonable to run.

The Visionstar WS-YDB range offers three horizontal cylindrical vessels at 150L, 200L and 280L, with chambers of 440 by 1000mm, 515 by 1000mm and 600 by 1000mm. All three share a working pressure of 0.22 MPa, a working temperature of 134 degrees, temperature adjustment from 40 to 134 degrees and heat average within plus or minus 2 degrees. Sterilising and drying are each timed separately across 0 to 99 minutes, the course is computer controlled, a printer is fitted, the door interlocks below 0.027 MPa, the safety valve opens above 0.24 MPa with steam exhausting to the water tank, and low water cuts power and raises an alarm. Weights run from 430kg to 570kg gross.

One figure should be established rather than assumed. Temperature adjustment is listed from 40 degrees, well below any sterilising condition, and presumably relates to the drying function. The electrical specification is not reproduced here, though the power requirement is well beyond a bench unit and the supply will need arranging. Documentation, configuration and condition do not appear on the material held, and nothing here should be read as a claim about testing or regulatory approval.
