Blackstone WF-360SM

Product Code: STDI-SE-3818

Neither door opens while the other stands open.

Because its two doors are interlocked, the WF-360SM keeps the packing room and sterile store separate, while vacuum pulses clear its 360-litre chamber, then sterilises it at 0.23 MPa and 115 to 138 °C.

The WF-360SM from Blackstone is a 360-litre double-door pulsating-vacuum steam steriliser built for pass-through installation in high-volume sterile services departments. Within vessel limits of −0.1 to 0.3 MPa and 150 °C, it operates at 0.23 MPa across 115 to 138 °C, after vacuum pulses to −0.086 MPa clear the air. Each load can use 25 kg of steam (0.3 to 0.6 MPa), 200 kg of water (0.1 to 0.2 MPa) and compressed air at 0.4 to 0.7 MPa. S denotes the double door, M the pulsating vacuum.

The door system is the defining feature because, on a pass-through steriliser, two doors carry the safety case. The manufacturer describes geared door locks secured electrically, pneumatic door seals and an interlock that keeps one door locked. At the same time, the other is open, so the chamber never becomes an open passage between the two rooms. Responsibility still rests with the owner. In Great Britain, the vessel, its doors and its supplies sit under a written scheme of examination, and the department decides where a load goes when a cycle fails.

The sheet gives the chamber as 1,000 × 600 × 600 mm (L × W × H), while a series description calls the inner chamber circular and jacketed, so the usable load space depends on the loading system. Series listings include touch-screen controls, traceable cycle reports and a verification port. Its three-phase 380 V 50 Hz supply must carry up to 35 kW, roughly 53 A per phase. The enquiry team shares the programme list, cycle times, usable module count and the interlock logic after an aborted cycle.

Its cabinet runs 1,250 mm from door to door, 1,300 mm wide and 1,900 mm high. Medigear. UK offers it to buyers in more than 80 countries, and the enquiry team provides stock and lead time.

High-volume sterile services departments are the natural home for the WF-360SM, along with dental hospital decontamination units and large day surgery centres built around a segregated packing room and sterile store. Its pulsating vacuum suits wrapped instrument trays, rigid containers, surgical textiles and lumened instruments, and the metre-long chamber accommodates long orthopaedic and general sets laid flat.

The safety record of equipment like this rests on its doors. HSE guidance note PM73 classes autoclaves as high-risk equipment, describes a fatal accident in which a door opened while still under pressure, and warns that on larger autoclaves residual pressure may not register on the gauge. The same guidance expects door interlocks and nil-pressure checks to be engineered in, and periodic examination to cover them.

A pass-through unit doubles those demands, with two doors, two sets of seals and an interlock between them. In practice, the risk transfers to the owner at handover. The written scheme, interlock testing, operator training and the failed-cycle procedure are the department's to maintain, and they decide whether the barrier between packing and sterile areas holds in daily use. Staff on both sides of the wall need the same training, because either team may spot a door or seal fault.

Health services that buy through formal tenders, including the NHS, require EN 285 evidence and a validation plan for sterilisers of this size, and public buyers in other countries expect much the same. The conformity documentation those procurement routes require is issued by the manufacturer and shared by the enquiry team.

Doors That Cannot Open Together

The manufacturer describes a double-door interlock for the series, so one door stays locked while the other is open. The packing room and the sterile store never share air through the chamber.

Electrically Locked Door Gear

Each door closes on a geared mechanism secured by an electric lock, according to the manufacturer's description. Securing the door therefore does not rest on an operator's grip alone.

Pneumatic Door Seals

The manufacturer describes pneumatic door seals that inflate from the compressed air supply. Seal condition becomes a routine inspection item, which keeps steam and pressure where they belong.

A Barrier Built Into the Building

Mounted through the partition, the steriliser becomes part of the wall between the packing room and sterile store. Processed loads leave on the far side, keeping each zone's staff, air and surfaces separate.

A Metre of Chamber Length

A 1,000 mm chamber takes long instrument sets without bending them into a shorter space. Trays that would otherwise need splitting can travel as one load.

Verification Port for Validation

The manufacturer lists a standard equipment verification interface. Validation engineers can connect test sensors through it, which makes the thermometric tests in the validation programme simpler to set up.

Air Out of Packs Before Sterilising

Vacuum pulses to −0.086 MPa draw trapped air from wrapped trays, textile packs and lumens. Steam can then reach the inner layers of each pack during the hold.

Traceable Cycle Reports

Series listings describe report processing and traceability for every cycle. Each load can be tied to its programme and parameters, which is the trail sterile services audits follow.

Utility Demands Set Out in Advance

Steam, water, compressed air and electrical demand are all stated per cycle on the sheet. Estate teams can design every supply before opening the partition.

360-Litre Chamber

The Blackstone sheet lists the chamber as 1,000 × 600 × 600 mm (L × W × H), and a series description calls it circular with a jacket.

Double Door, Code S

S identifies the sterile-side door, the exit for a load after a completed cycle.

Pulsating Vacuum, Code M

M identifies the vacuum pulses that take the chamber to −0.086 MPa before sterilising begins.

Working Range

Working pressure is 0.23 MPa, and temperatures range from 115 to 138 °C, covering the usual 121 °C and 134 °C settings.

Design Limits

The vessel is designed for −0.1 to 0.3 MPa and up to 150 °C, spanning every vacuum and pressure phase of a cycle.

Temperature Uniformity

Chamber temperature stays within ±2.0 °C across the load space, the benchmark for thermometric validation.

Steam Supply

Site steam enters at 0.3 to 0.6 MPa, and each cycle uses up to 25 kg.

Water Supply

Water enters at 0.1 to 0.2 MPa, with up to 200 kg per cycle discharged to drain.

Compressed Air

A supply at 0.4 to 0.7 MPa feeds the pneumatic door seals, so the air system is part of the steriliser's safety case.

Electrical Supply

Three-phase five-wire AC 380 V 50 Hz power, up to 35 kW, about 53 A per phase, fed from a dedicated circuit.

Electric Door Locking

The manufacturer describes a disc-type geared door structure with an electric lock, fitted to each door of the double-door version.

Touch-Screen Controls

Series descriptions list an HMI touch screen for programme selection and parameter setting.

Stainless Pipework

The manufacturer describes stainless steel pipework with clamp fittings, laid out for quick assembly and maintenance access.

Sterilisation Basket

Series listings include a basket for the WF-150 through the WF-360, and the enquiry team can arrange additional baskets.

Optional Steam Generator

Sites without a suitable steam main can specify the built-in generator offered in a series listing, which adds electrical load.

Cabinet Size and Weight

The cabinet measures 1,250 × 1,300 × 1,900 mm and weighs 950 kg net, 1,130 kg gross.

The WF-360SM suits high-volume sterile services departments, dental hospital decontamination units and large day surgery centres that run a segregated packing room and sterile store, and that can supply 35 kW, water, compressed air, steam and drainage. It is the wrong choice for single-room decontamination, for buildings that cannot accommodate a 1,300 × 1,900 mm wall opening, and for departments without the engineering support to keep two doors and an interlock examined. Before ordering, agree the written scheme, the interlock testing regime and the failed-cycle procedure, and commission the floor and partition checks. Medigear.uk lists the WF-360SM for business buyers worldwide and can arrange delivery, installation, commissioning, familiarisation and service cover. Ask the enquiry team for the interlock logic, installation drawing, module count, and EN 285 evidence before ordering.

FAQ

Frequently Asked Questions

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

The owner or user does. In Great Britain, the Pressure Systems Safety Regulations 2000 make the owner responsible for a written examination scheme. A competent person prepares it, covering the vessel, its door safety devices and the steam and compressed air supplies, and sets the examination intervals. Industry guidance for writing those schemes expects the interlocks on quick-opening doors to be examined as safety devices. Operators also need PUWER training before they run the machine.

HSE guidance treats autoclaves as high-risk equipment, not least because a door opened under pressure releases its force violently. The manufacturer describes electrically locked, geared door mechanisms and pneumatic seals for this series. HSE also warns that on larger autoclaves residual pressure may not register on the gauge, so the opening procedure deserves as much attention as the hardware, and the interlocks need routine testing by a competent engineer.

The interlock logic of the quoted unit comes from the enquiry team, and it should settle this question before ordering. Many pass-through installations keep the sterile-side door locked after an aborted cycle, so the load returns through the packing room for reprocessing. The department's procedure for a failed cycle, including who releases or rejects the load, belongs in its written instructions from the first day of use.

The cabinet sits in the partition between the two rooms, so the opening must take its 1,300 × 1,900 mm cross-section plus a sealing frame. A fire-rated partition must maintain its rating once the opening and seals are in place. The installation drawing, covering the opening, the sterile-side controls and the steam arrangement, comes from the enquiry team with the quotation.

Power comes first: up to 35 kW from a dedicated three-phase five-wire circuit at 380 V 50 Hz, about 53 A per phase, installed to BS 7671. Water arrives at 0.1 to 0.2 MPa, up to 200 kg each cycle, and leaves through a drain rated for hot discharge, behind backflow protection. Compressed air at 0.4 to 0.7 MPa serves the pneumatic seals, and site steam at 0.3 to 0.6 MPa supplies up to 25 kg per cycle unless the optional generator-in-series listing is specified.

On the Blackstone sheet t, he chamber is 1,000 mm long with a 600 × 600 mm cross-section, a metre of length that suits long instrument sets. A series description calls the inner chamber circular, and a 600 mm circle cannot hold the two-by-two stack of standard 300 × 300 × 600 mm modules that a 600 mm square could. The enquiry team therefore provides the usable module count along with the programme list.

The sheet gives 950 kg net and 1,130 kg gross. Spread over the 1,250 × 1,300 mm footprint, 950 kg is about 585 kg per square metre before water, which warrants a structural check of the floor. Every opening on the route must clear the crated unit, and LOLER requires a competent person to plan the lift into the wall opening.

EN 13060, the source of the Class B label, applies only to small sterilisers under 60 litres that cannot take a sterilisation module. A 360-litre pass-through unit is a large steriliser under EN 285, so ask for the manufacturer's test results against that standard and base validation on EN ISO 17665.

Validation and periodic testing follow Part C of HTM 01-01 in England and of SHTM 01-01 in Scotland, including Bowie-Dick, air leakage and steam quality tests. Interlock and door safety checks belong in the same programme, since both doors depend on them. Medigear.uk can arrange installation, commissioning and service cover.

Series listings describe report processing and traceability for each cycle so that you can trace a load to its programme and parameters. The record format comes with the programme list from the enquiry team, which shows how records will reach the department's tracking system.

The WF-360SM 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 unit of this capacity, it should cite EN 28, EN 61010 -1, and EN 61010-2-040.
