Visionstar TM-XDD

Three or More Pulse Vacuum Stages

Pulse vacuum exhausting runs at least three times, applied by the manufacturer to wrapped or unwrapped objects and to hollow equipment that would otherwise trap air.

Drying Function

A drying function is fitted, so wrapped and packaged loads come out dry at the end of a cycle rather than damp and vulnerable to recontamination in storage.

Inner Printer

An inner printer records the full procedure of the sterilisation, producing a written record of each cycle without anything being transcribed from a display.

Steam Penetration Testing

A Bowie and Dick testing function is described for steam penetrating testing, so the periodic check can be run on the same machine that processes the loads.

Four Chamber Capacities

Volumes of 20L, 24L, 35L and 50L are offered, at 250 by 420mm, 250 by 520mm, 300 by 500mm and 340 by 550mm respectively across the four models.

Shared Operating Parameters

Working temperature is 134 degrees on every model, with a 105 to 134 degree adjust range, a 0 to 99 minute timer, heat average within plus or minus 1 degree and 0.22 MPa working pressure.

Four Safety Functions

Safety locking, over pressure protection, low water protection and over current protection are all listed, with the door held shut while inner pressure exceeds 0.027 MPa.

Automatic and Self Testing

The sterilising procedure is automatically controlled and described as needing no supervision, with a self-testing malfunction function provided for maintenance.

Hollow Instruments and Wrapped Packs

The manufacturer names wrapped, unwrapped and hollow objects quite specifically, and the repeated pulse vacuum is what makes that claim credible in practice. Air sitting inside a lumen or against the instruments within a pack is what prevents steam contacting the surface, and no amount of extra time at temperature compensates. Active extraction is the only thing that addresses that particular problem properly, which is exactly why it is provided.

Practices Keeping Decontamination Records

An inner printer producing a record of each full procedure genuinely changes what a practice can demonstrate. Where a written procedure requires evidence that cycles reached their conditions, a printed record from the machine itself is considerably stronger evidence than a note taken from a display, and it removes the transcription step where errors ordinarily enter a practice record.

Departments Running Periodic Tests

A Bowie and Dick function for steam penetration testing means the routine check happens upon the same unit without additional equipment or any service visit. Testing that is easy to run is the testing that actually gets run, and for a small practice without any dedicated decontamination lead, that practical difference decides whether the checks happen at all in a smaller practice setting.

Growing Practices and Mixed Settings

Four capacities from 20L to 50L on a single specification let a practice size the chamber to its own actual throughput. Because every model shares exactly the same temperature range, timing, protections and testing provision, a unit bought for one site behaves identically to any unit bought for another, which simplifies both training and written procedure across several separate practice locations.

Loads a Simpler Machine Cannot Process

The repeated pulse vacuum is the whole difference between this range and a plain bench steriliser. Wrapped packs and hollow instruments are precisely the loads that defeat a machine relying on steam displacement, and they are also the loads most practices actually generate. For anything beyond loose unwrapped instruments, active air removal determines whether the equipment is fit for that particular work at all.

Evidence Produced by the Machine

An inner printer and a built in steam penetration test together mean the equipment supports the paperwork rather than merely performing the process. A practice can show what each cycle did and that its air removal was checked, both from the same unit. Where decontamination is inspected, equipment that documents itself is worth considerably more than equipment that leaves the recording to whoever happens to be on duty.

Protection That Acts Rather Than Warns

Four separate protections cover the door, the pressure, the water level and the electrical supply, and each acts rather than simply signalling. The door will not open while inner pressure exceeds 0.027 MPa, the valve exhausts if working pressure is passed, and power cuts directly on low water or over current. For a machine described as needing no supervision, protections that intervene are what make that description reasonable.

The Visionstar TM-XDD range offers four bench sterilisers at 20L, 24L, 35L and 50L, with chambers from 250 by 420mm to 340 by 550mm. All four share a working temperature of 134 degrees, a 105 to 134 degree adjust range, a 0 to 99 minute timer, heat average within plus or minus 1 degree and 0.22 MPa working pressure. Pulse vacuum exhausting runs at least three times for wrapped, unwrapped and hollow objects, a drying function and inner printer are fitted, a Bowie and Dick steam penetration test function is described, and four safety functions cover the door, pressure, water level and current.

Two gaps should be noted. The power figure for the largest model is missing from the card, and the electrical specification is not reproduced here in any case. Documentation, configuration and condition do not appear on the material held, and nothing on this page should be read as a claim about testing or regulatory approval.
