Built by Blackstone, the WF-1200SM is a 1,200-litre, double-door pulsating-vacuum steam steriliser for central and off-site sterile services with site steam. Its vessel has a design rating of −0.1 to 0.3 MPa at 150 °C, and after vacuum pulses to −0.086 MPa, the load is held at 0.23 MPa within 115 to 138 °C. Each cycle can use up to 50 kg of steam supplied at 0.3 to 0.6 MPa and 200 kg of water fed at 0.1 to 0.2 MPa, plus compressed air at 0.4 to 0.7 MPa. S denotes the second door and M the pulsating vacuum.

Maintainability is the defining feature. The manufacturer describes clamp-fitted stainless pipework laid out for maintenance and a verification port that eases testing. Both matter because one 1,200-litre chamber can carry most of a department's daily work. When it stops, theatre lists wait, so inspections, consumables, spares and service response decide how available it really is. A door design and control system common to the series simplifies training and spares wherever several units share a department.

Its 1,450 × 680 × 1,180 mm chamber (L × W × H) matches twelve 300 × 300 × 600 mm modules on paper, before the sterilisation car takes its share. Series listings supply that car and a loading car, and the manufacturer describes electrically locked geared doors, pneumatic seals and a double-door interlock. The sheet gives up to 6.0 kW, and no built-in generator is listed at this size. The enquiry team shares cycle times, the usable module count, the recommended spares and the service schedule.

From door to door, it measures 1,700 mm, with a 1,440 mm width and a 1,950 mm height.UK offers to buyers in more than 80 countries, and the enquiry team provides stock and lead time details.

Central and off-site sterile services with site steam, segregated packing and sterile rooms, and theatre lists across several hospitals are the natural home for the WF-1200SM. Wrapped trays, rigid containers, heavy orthopaedic and implant sets, textiles, and lumened instruments all suit its pulsed-vacuum cycles, and long sets fit flat in a chamber 1,450 mm deep.

A chamber this size concentrates a department's capacity, and recent incidents show what an outage means in clinical time. A mechanical fault in the sterile services department of Wirral University Teaching Hospital forced the cancellation of more than 1,300 elective theatre cases. Patients waiting over 65 weeks rose from 4 to 26, with 21 of the increase put down to the incident. In Aberdeen, closing the central decontamination unit postponed 120 elective operations and 100 dental procedures, and the unit was expected to take several weeks to return to full operation. When a hospital in northern Canada lost its main steriliser, its smaller backup units could handle only limited quantities, and elective surgery was cancelled.

Those cases make the whole-life plan as important as the specification. Service response times, on-site spares holding, a validated fallback such as a second steriliser or a mutual-aid agreement, and test schedules that avoid peak theatre days all keep the chamber, and the lists that depend on it, running.

Public tenders, including those run for the NHS, ask for EN 285 evidence and a validation plan for a steriliser this large, and procurement bodies abroad expect the same. The manufacturer issues the conformity documentation those procurement routes require, and the enquiry team shares it.

Pipework Laid Out for Maintenance

The manufacturer describes stainless steel pipework joined with clamp fittings and arranged for maintenance and cleaning. Engineers can quickly open and reassemble sections, shortening repair visits.

A Verification Port That Eases Testing

A standard equipment verification interface gives validation engineers a ready connection for their sensors. Periodic thermometric testing takes less setup, so the chamber returns to service sooner.

One Design Across the Series

The door design and control system are common to the series. Departments running more than one unit can train staff once and keep controls and procedures familiar from machine to machine.

Modest Electrical Demand on Site Steam

The Blackstone sheet rates the unit at up to 6.0 kW, with site steam doing the heating. The electrical side adds little to the building's existing supply.

Zones Kept Apart by Design

Each batch passes from the packing side to the sterile side, with an interlock keeping one door closed while the other is open. Each team works on its own side of the wall.

Batches Built at Bench Height

The sterilisation car is loaded at the packing bench and rolled in from the loading car. Heavy trays stay at a comfortable working height throughout.

Twelve Modules on Paper

The chamber's geometry matches twelve standard modules before the car takes its share. Large batches mean fewer loading episodes across a shift.

Records for Audit and Investigation

Series listings describe report processing and traceability for each cycle. Records link every batch to its programme, supporting routine audits and investigations after a fault.

Supply Figures for Every Service

The sheet states steam, water, compressed air and electrical demand per cycle. Estate teams can plan each supply and its maintenance before opening the partition.

1,200-Litre Chamber

The chamber measures 1,450 mm long, 680 mm wide and 1,180 mm high.

Double Door, Code S

S identifies the second door, which opens into the sterile store after a completed cycle.

Pulsating Vacuum, Code M

M identifies the vacuum pulses that reach −0.086 MPa before sterilising.

Operating Range

The working pressure is 0.23 MPa, across sterilising temperatures from 115 to 138 °C.

Design Limits

Rated for −0.1 to 0.3 MPa and a design temperature of 150 °C, the vessel spans every phase of the cycle.

Uniformity

Chamber temperature stays within ±2.0 °C according to the sheet, the figure that thermometric validation checks.

Steam

External steam at 0.3 to 0.6 MPa, with up to 50 kg consumed per cycle.

Water

Up to 200 kg per cycle, supplied at 0.1 to 0.2 MPa and discharged to drain.

Compressed Air

A 0.4 to 0.7 MPa supply serves the pneumatic door seals.

Electrical

The Blackstone sheet rates it at up to 6.0 kW on three-phase, five-wire AC at 380 V, 50 Hz, versus 4.5 kW in a series listing.

Stainless Clamp Pipework

The manufacturer describes SUS304 stainless pipework with clamp fittings for quick assembly and maintenance.

Verification Interface

A standard equipment verification interface accepts validation sensors.

Door Hardware

The manufacturer describes disc-type geared doors with electric locks, pneumatic seals, and a double-door interlock.

Touch-Screen HMI

The manufacturer lists a touch-screen interface for programme selection and parameter setting.

Sterilisation Car and Loading Car

Series listings supply both cars for WF models of 600 litres and above.

Cabinet Size and Weight

The cabinet measures 1,700 × 1,440 × 1,950 mm and weighs 1,730 kg net and 1,950 kg gross on the Blackstone sheet.

The WF-1200SM suits central and off-site sterile services with site steam, segregated packing and sterile rooms, and the engineering support to keep a large pass-through steriliser examined, tested and serviced. It is the wrong choice for sites without steam, for low volumes, and for departments that would depend on it with no fallback in place. Before ordering, confirm service cover and response times, on-site spares holding, a fallback arrangement for outages, and the wall opening, floor, and delivery route. Medigear.uk lists the WF-1200SM for business buyers worldwide and can arrange delivery, installation, commissioning, familiarisation and service cover. Ask the enquiry team for the recommended spares list, service schedule, interlock logic, and EN 285 test results before ordering.

FAQ

Frequently Asked Questions

Everything buyers need to know about sourcing medical equipment through MediGear.

Three things recur throughout its life. Statutory examination under the Pressure Systems Safety Regulations 2000 covers the vessel, door safety devices, and the steam and compressed air supplies, at intervals set out in the written scheme. Routine testing under HTM 01-01 Part C, or SHTM 01-01 Part C in Scotland, runs on daily, weekly, quarterly and yearly cycles. Consumables such as test packs, indicators and door seals need replacing on the manufacturer's schedule.

Theatre lists stop with it. A mechanical failure in one English trust's sterile services department left residue on instruments and led to more than 1,300 elective cases being cancelled. In Aberdeen, a central decontamination unit closed after a substance thought to come from a faulty compressor appeared on instruments, postponing 120 elective operations and 100 dental procedures. Service cover, spares and a fallback arrangement belong in the plan before installation.

The enquiry team shares the manufacturer's recommended spares list with the quotation. Wear items such as door seals are the usual starting point, and the list should be agreed with whoever provides service cover, so that the parts most likely to stop the machine are on the shelf, not on a lorry.

The manufacturer describes stainless steel pipework joined with clamp fittings and laid out for maintenance access, so an engineer can open the system without cutting or welding. A standard verification interface lets validation sensors connect without improvised entry points. Both shorten the hours the chamber spends out of use for servicing and testing.

The chamber is 1,450 mm long, 680 mm wide and 1,180 mm high. Two modules fit along it with 250 mm spare, two across with 80 mm and three high with 280 mm, twelve in total on paper. The sterilisation car occupies some of that space, and the enquiry team states the usable count.

Site steam at 0.3 to 0.6 MPa, up to 50 kg per cycle, which sets the boiler capacity, plus main and condensate return. Water arrives at 0.1 to 0.2 MPa, up to 200 kg per cycle, with backflow protection and a drain for hot discharge. Compressed air at 0.4 to 0.7 MPa, and a three-phase, five-wire 380 V, 50 Hz supply rated for the sheet's 6.0 kW (about 9 A per phase); a series listing gives 4.5 kW.

The cabinet fills a 1,440 × 1,950 mm opening in the partition, plus a sealing frame that maintains the wall's fire rating. At 1,730 kg net on a 1,700 × 1,440 mm footprint, it loads the floor at roughly 710 kg per square metre before water, which a structural engineer should assess. The 1,950 kg consignment needs a route measured in advance and a lift planned by a competent person under LOLER.

The manufacturer describes a double-door interlock, so one door stays locked while the other is open. Batches enter on the packing side and exit on the sterile side. Whether the sterile-side door also stays locked after an aborted cycle depends on the interlock logic the enquiry team sets out in the installation drawing.

EN 13060 issues the Class B grade, but only for sterilisers under 60 litres that cannot hold a sterilisation module. A 1,200-litre chamber is governed by EN 285 instead, so ask the manufacturer for its EN 285 test results and plan validation to EN ISO 17665.

Series listings describe report processing and traceability, linking each batch to its programme and parameters. The enquiry team shares the record format, which shows how cycle data will reach the department's tracking system and audit trail.

The WF-1200SM is typically Class IIa under UK MDR 2002, or higher depending on use, as stated on the manufacturer's declaration of conformity, which the enquiry team shares. The declaration identifies the legal manufacturer and, for a pass-through steriliser of this capacity, should list EN 285 alongside EN 61010-1 and EN 61010-2-040.
