Blackstone WF-600DM

Product Code: STDI-SE-3819

Loads roll into the chamber on a trolley, with no lifting at the door.

If a department sterilises in large batches, the WF-600DM takes each batch into its 600-litre chamber on a sterilisation car, removes air with vacuum pulses, and sterilises at 115 to 138 °C under 0.23 MPa.

Blackstone's WF-600DM is a 600-litre single-door pulsating-vacuum steam steriliser designed around trolley loading. Cycles run at 0.23 MPa and 115 to 138 °C inside a vessel rated for −0.1 to 0.3 MPa and 150 °C, preceded by vacuum pulses that take the chamber to −0.086 MPa. Steam at 0.3 to 0.6 MPa (up to 30 kg per cycle), water at 0.1 to 0.2 MPa (up to 210 kg) and compressed air at 0.4 to 0.7 MPa feed it. The model code reads D for single door and M for pulsating vacuum.

Trolley loading is the defining feature, and its benefit is measured in staff effort. Series listings equip WF models from 600 litres upward with a sterilisation car and a loading car, so trays go onto the car at the packing bench, and the whole batch rolls into the chamber. Trays are placed and retrieved outside the hot vessel, and every shift learns one transfer routine. The trade-off is pushing and pulling a heavy car, which needs smooth floors, good wheels and a clear run in front of the door.

On paper, the 1,190 × 610 × 910 mm chamber (L × W × H) would take six standard 300 × 300 × 600 mm modules, two across and three high, with 10 mm to spare each way. The car occupies part of that space. The manufacturer describes an electrically locked geared door, a pneumatic door seal, touch-screen controls and a verification port. Power reaches 50 kW, about 76 A per phase. The enquiry team provides programme details, cycle times, the usable module count, and the car dimensions.

The cabinet measures 1,440 mm long, 1,310 mm wide and 1,900 mm high. Medigear.UKk offers it to buyers in more than 80 countries, and the enquiry team provides stock and lead time.

Central sterile services departments that supply several theatre suites, large dental hospitals and regional decontamination units are where a 600-litre trolley-loaded chamber fits. Wrapped instrument trays, rigid containers, surgical textiles, lumened instruments and bulky orthopaedic sets all suit its pulsed-vacuum cycles, and the car lets a full batch move as one load. In departments that run two or three shifts, the loading routine repeats many times a day, so its demands on staff add up quickly.

The case for trolley loading rests on the people doing the work. A survey of 142 central sterile supply technicians across 23 hospitals in Thailand found a 12-month prevalence of musculoskeletal disorders of 70.4%, with the lower back most often affected. In a Brazilian sterile supply department, almost a third of the nursing professionals surveyed had been functionally readapted, alongside a high prevalence of work-related musculoskeletal disorders and repetitive strain injuries.

Occupational safety guidance for sterile supply areas points in the same direction, naming repeated reaching and lifting as hazards and recommending carts with large, low-resistance wheels. Pushing and pulling heavy carts appears on the same hazard list, so a trolley moves the effort without removing it. Smooth floors, well-maintained wheels, and a clear approach to the door determine how much strain the cart actually saves.

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

Trays Loaded at Bench Height

Staff fill the sterilisation car at the packing bench, at a comfortable working height. Heavy trays never have to be held at arm's length over a chamber threshold.

Nothing Placed Into a Hot Chamber

The car carries the batch in and brings it back out, so hands stay outside the vessel at both ends of the cycle. Reaching over a hot threshold has no place in the routine.

One Routine Across Every Shift

Every load follows the same sequence of filling, docking and rolling in. New and rotating staff learn it once, which keeps induction short and practice consistent.

Large Batches per Cycle

A 600-litre chamber with room for six modules on paper means each cycle moves a substantial batch. A day's workload passes through in a modest number of loading episodes.

Loads Cool on the Car

After the cycle the car rolls back onto the loading car, where hot trays can cool before anyone touches them. Handling waits until the load is safe to hold.

Air Cleared From Packs and Lumens

Pulses down to −0.086 MPa pull air out of wrapped trays, textile packs and cannulated instruments. Steam then reaches the innermost layers throughout the hold.

A Locked Door With a Pneumatic Seal

The manufacturer describes a geared door secured by an electric lock and sealed pneumatically. Securing the door does not rely on an operator's strength.

Records for Each Batch

Series listings describe report processing and traceability for every cycle. Each car's contents can be traced to the programme and parameters that processed them.

Utility Demands Known per Cycle

The sheet lists up to 50 kW, 210 kg of water, and 30 kg of steam per cycle. Estate teams can size every supply before the steriliser arrives.

600-Litre Chamber

The chamber measures 1,190 mm long, 610 mm wide and 910 mm high, a tall cross-section suited to tiered loading on the car.

Sterilisation Car and Loading Car

Series listings equip models from 600 litres upward with a sterilisation car for the chamber and a loading car for transfer.

Single Door, Code D

D marks the single door, through which every load enters and leaves.

Pulsating Vacuum, Code M

M marks the repeated vacuum pulses that take the chamber to −0.086 MPa before sterilising.

Operating Conditions

Cycles hold 0.23 MPa at temperatures between 115 and 138 °C, including 121 °C and 134 °C programmes.

Vessel Design

Design limits of −0.1 to 0.3 MPa and 150 °C cover every vacuum and pressure phase in the cycle.

Uniformity Within ±2.0 °C

The sheet specifies chamber temperature uniformity of ±2.0 °C, measured at validation across the load space.

Steam Inlet

External steam at 0.3 to 0.6 MPa, up to 30 kg per cycle, sizes the steam branch and condensate return.

Water Inlet

Water at 0.1 to 0.2 MPa, up to 210 kg per cycle, all of it leaving through the drain.

Compressed Air

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

Electrical Supply

Power comes from a three-phase, five-wire AC supply at 380 V, 50 Hz, drawing up to 50 kW (roughly 76 A per phase).

Electric Door Lock

The manufacturer describes a disc-type geared door with an electric lock.

Touch-Screen HMI

The manufacturer states that programme selection and parameter setting run from a touch-screen interface.

Verification Interface

A standard equipment verification interface gives validation engineers a connection point for test sensors.

Optional Steam Generator

For sites without suitable steam, a series listing offers a built-in generator, which increases electrical demand.

Cabinet Size and Weight

The cabinet measures 1,440 × 1,310 × 1,900 mm and weighs 1,240 kg net and 1,440 kg gross on the Blackstone sheet.

The WF-600DM suits central sterile services departments, large dental hospitals and regional decontamination units that process at volume and want their staff loading at bench height. It is the wrong choice for departments whose batches would leave the chamber largely empty, for layouts needing a pass-through barrier, and for buildings that cannot supply 50 kW or carry a 1,440 kg crate. Before ordering, complete the floor check, confirm a delivery route clear to 1,310 by 1,900 mm, confirm space for the loading car, and complete a manual handling assessment covering the car itself. Medigear.uk lists the WF-600DM for business buyers worldwide and can arrange delivery, installation, commissioning, familiarisation and service cover. Ask the enquiry team for the car dimensions, usable module count, cycle programmes, and the manufacturer's EN 285 test results before ordering.

FAQ

Frequently Asked Questions

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

Series listings include two trolleys for this size: a sterilisation car that carries the trays through the cycle, and a loading car that brings them to the door. Staff fill the car at the packing bench, dock the loading car and roll the batch into the chamber. Afterwards,s the car comes back out onto the loading car, so a hot load can cool before anyone handles the trays. Shelf spacing and docking height come from the enquiry team.

Trays are handled at bench height and never placed into, or lifted out of, a hot chamber. One routine covers every load, which keeps induction short for new and rotating staff. The effort shifts from lifting to pushing and pulling, so the loaded car belongs in the manual handling risk assessment required by the Manual Handling Operations Regulations 1992, with attention to floor surfaces, thresholds, and wheel condition.

The chamber measures 1,190 mm long, 610 mm wide and 910 mm high. Its cross-section allows two standard modules across and three high,h with about 10 mm of clearance in each direction, and one module fits along the length with 590 mm left over. The sterilisation cart takes up some of that space so that the enquiry team will confirm the usable module count in the quotation.

A three-phase, five-wire 380 V, 50 Hz supply with a 50 kW capacity, which works out to about 76 A per phase. This requires a dedicated feed from the main distribution board, installed to BS 7671 in the UK. The optional built-in steam generator mentioned in a series listing draws on the same supply, so the full 50 kW is the safe planning figure.

Water arrives at 0.1 to 0.2 MPa, with up to 210 kg drawn per cycle, behind backflow protection, and leaves through a drain that has to handle hot discharge. Compressed air at 0.4 to 0.7 MPa serves the pneumatic door seal. Site steam enters at 0.3 to 0.6 MPa, up to 30 kg per cycle, and is tested during validation against EN 285 criteria for non-condensable gas content, superheat, and dryness.

The crate weighs 1,440 kg, and the cabinet's narrowest plan dimension is 1,310 mm, so every door, corridor and lift on the route needs measuring. At 1,240 kg net over a 1,440 × 1,310 mm footprint, the floor carries about 660 kg per square metre before water, which needs a structural check. The loading car also needs a clear run in front of the door, which the installation drawing shows. Positioning a crate this heavy is a lifting operation, and under LOLER a competent person plans it.

The Class B label belongs to EN 13060, which stops at 60 litres and at chambers too small for a sterilisation module. A 600-litre chamber is squarely in the scope of EN 285 for large steam sterilisers. Request the manufacturer's test results against EN 285, and plan the validation to EN ISO 17665.

In Great Britain, the vessel, its door safety devices, and its steam and compressed air supplies fall under the Pressure Systems Safety Regulations 2000. A competent person prepares the written scheme of examination and sets its intervals. Validation and periodic testing, including Bowie-Dick, air leakage and steam quality, follow HTM 01-01 Part C in England or the Scottish SHTM 01-01 Part C. Medigear.uk can arrange installation, commissioning and service cover.

Report processing and traceability appear in series listings for each cycle, linking every batch on the car to its programme and parameters. Ask the enquiry team for the record format alongside the programme list, to see how records will join the department's tracking system.

The WF-600DM 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. That document names the legal manufacturer and, for a steriliser of this scale, should cite EN 285 alongside EN 61010-1 and EN 61010-2-040.
