Blackstone WF-1000DM

Product Code: STDI-SE-3821

A heated jacket and a closing vacuum dry the load before the door opens.

Whether the load is textiles, gowns or heavy instrument sets, the WF-1000DM clears air with vacuum pulses, sterilises at 115 to 138 °C and finishes with vacuum drying inside its jacketed 1,000-litre chamber.

Blackstone positions the WF-1000DM as a 1,000-litre single-door pulsating-vacuum steam steriliser for central sterile services departments with site steam. Steam enters at 0.3 to 0.6 MPa, up to 42 kg per cycle, and the vessel is rated for −0.1 to 0.3 MPa and 150 °C. Pulses to −0.086 MPa remove air before a hold at 0.23 MPa and 115 to 138 °C. Compressed air at 0.4 to 0.7 MPa and water at 0.1 to 0.2 MPa, up to 200 kg per cycle, complete the supplies, while D and M mark the single door and pulsating vacuum.

The jacketed chamber is the defining feature. Series descriptions describe a jacket around the chamber and a drying stage that combines vacuum with moisture removal. As steam heats a heavy load, it condenses on the metal, and the hot jacket walls help turn that water back into vapour for the vacuum to draw off. That matters because a wet pack counts as contaminated and must be returned for reprocessing. Loading, packaging and steam quality still shape the result.

On paper the 1,250 × 680 × 1,180 mm chamber (L × W × H) holds twelve standard 300 × 300 × 600 mm modules, leaving 80 mm across and 280 mm above the stack for the car. Series listings supply the sterilisation car and loading car, and the manufacturer describes an electrically locked geared door with a pneumatic seal. The sheet gives up to 5.0 kW, and a series listing names no generator at this size, so site steam is required. The enquiry team shares drying times, the usable module count and the car dimensions.

The cabinet is 1,500 mm long, 1,440 mm wide and 1,950 mm tall. Medigear.uk offers it to buyers in more than 80 countries, and the enquiry team provides stock and lead time.

Central sterile services departments and off-site hubs are where a 1,000-litre chamber earns its floor space, especially for reprocessing heavy orthopaedic sets, loaned implant kits, and, where still in use, reusable surgical gowns, drapes, and other textiles. Its pulsating vacuum also suits wrapped trays, rigid containers and lumened instruments.

Heavy, dense loads are where drying is hardest. The weight of metal in a load sets how much condensate forms as steam heats it, and residual water left in a pack after the cycle makes it a wet pack. A Chinese medical centre recorded 128 wet packs among 4,099 sterilised, with instrument packs about 3.3 times more likely to be wet than dressing packs and non-woven wraps more prone to wetness than cotton. Studies of loaned instruments, which tend to arrive in heavy containers, report wet-pack rates from roughly 13% to 37.5%.

The WF-1000DM answers that problem with a mechanism: a jacket that keeps the chamber walls hot and a vacuum drying stage that draws off the vapour. Neither replaces good practice. Set weights, shelf positions, packaging choices and steam dryness still decide whether a load leaves dry, and a validation programme should prove drying performance on the department's own heaviest sets.

Health services buying through formal tenders, the NHS among them, ask for EN 285 test evidence and a validation plan from sterilisers at this capacity, and public buyers in other countries require much the same. The manufacturer issues the conformity documentation those procurement routes require, and the enquiry team shares it.

A Jacket That Keeps the Walls Hot

Series descriptions give the chamber a surrounding jacket. Hot walls stop the chamber itself from adding condensate and help residual water flash back to vapour before the door opens.

Vacuum Drying to Finish Each Cycle

After sterilising, the drying stage combines vacuum with moisture removal, as the series describes it. Vapour leaves the chamber before staff handle the load.

Suited to Heavy Metal Loads

Dense instrument sets produce the most condensate as they heat. A drying stage built around jacket heat and vacuum targets that load type.

Textiles Ready for Inspection

Gowns, drapes and other textiles leave the chamber after vacuum drying, ready for the dryness check that release procedures require. Damp textiles are caught at inspection, before storage.

Room Around a Twelve-Module Stack

The chamber matches twelve modules on paper, with 80 mm across and 280 mm overhead to spare. That margin gives the car frame room without crowding the load.

A Small Electrical Load on Site Steam

The sheet rates the unit at up to 5.0 kW, because site steam does the heating. A department with boiler plant can add 1,000 litres of chamber without a major electrical upgrade.

Trolley Loading for Large Batches

Series listings supply a sterilisation car and loading car, so batches are assembled at bench height and roll into the chamber. Heavy sets never have to be lifted into a hot vessel.

A Locked Door With a Pneumatic Seal

The manufacturer describes a geared door secured by an electric lock and sealed with compressed air. Door security does not depend on an operator's strength.

Records That Trace Problems

Series listings describe report processing and traceability for every cycle. When a wet pack turns up, the department can trace it to the cycle, programme, and load that produced it.

1,000-Litre Chamber

The chamber measures 1,250 mm long, 680 mm wide and 1,180 mm high.

Jacketed Construction

Series descriptions give the range a jacket around the chamber for heat retention and drying.

Vacuum Drying

The drying stage pairs vacuum with moisture removal after sterilising, as described in the series.

Pulsating Vacuum, Code M

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

Single Door, Code D

D identifies the single door, used for both loading and unloading.

Working Pressure and Temperature

Sterilising takes place at 0.23 MPa and between 115 and 138 °C, covering 121 °C and 134 °C programmes.

Design Rating

The vessel's design range is −0.1 to 0.3 MPa, with a design temperature of 150 °C.

Temperature Uniformity

The sheet provides uniformity within ±2.0 °C across the chamber, as confirmed during thermometric validation.

Steam Feed

Site steam at 0.3 to 0.6 MPa, up to 42 kg per cycle.

Water Feed

Each cycle can draw up to 200 kg of water, supplied at 0.1 to 0.2 MPa and discharged to drain.

Compressed Air

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

Electrical Rating

Up to 5.0 kW from a three-phase five-wire AC 380 V 50 Hz supply on the Blackstone sheet; a series listing gives 3.5 kW with no generator option at this size.

Sterilisation Car and Loading Car

Series listings pair the WF range from 600 litres upward with a sterilisation car and a loading car.

Door Hardware

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

Touch-Screen HMI and Verification Interface

The manufacturer lists a touch-screen interface for programme selection and a standard equipment verification interface for validation sensors.

Cabinet Size and Weight

The cabinet measures 1,500 × 1,440 × 1,950 mm and weighs 1,550 kg net and 1,680 kg gross, per the Blackstone sheet.

The WF-1000DM suits central sterile services departments and off-site hubs with site steam that reprocess heavy instrument sets, loaned kits or textiles in large batches. It is the wrong choice for sites without steam, since no generator is listed at this size, for low volumes, and for buildings whose routes or floors cannot take a 1,950 mm, 1,680 kg crate. Before ordering, check boiler capacity for 42 kg per cycle, measure the delivery route, commission the floor assessment and plan validation around the department's heaviest sets. Medigear.uk lists the WF-1000DM for business buyers worldwide and can arrange delivery, installation, commissioning, familiarisation and service cover. Ask the enquiry team for the drying times, electrical rating, usable module count, and EN 285 test results before ordering.

FAQ

Frequently Asked Questions

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

Series descriptions give it a jacketed chamber and a drying stage that pairs vacuum with moisture removal after sterilising. Condensate forms whenever steam gives up its heat to the load, and the jacket keeps the chamber walls hot so that residual water can return to vapour and leave under vacuum. The enquiry team provides drying times for each programme with the programme list.

A pack with dampness, droplets or pooled water after a completed cycle is treated as contaminated and goes back for reprocessing. They are common: one Chinese medical centre found 128 wet packs among 4,099 sterilised (3.12%), and a survey in the same study found wet packs in 78% of 125 hospitals. Instrument packs there were about 3.3 times more likely to be wet than dressing packs.

Loading comes first: heavy instrument sets belong on lower shelves, and packs should not be stacked so condensate drips onto those below. Packaging matters too, since the same study found non-woven wraps far more prone to wetness than cotton. Steam dryness is checked against EN 285 at validation, and AAMI guidance in the United States caps instrument sets at 25 l (about 11 kg).

The chamber is 1,250 mm long, 680 mm wide and 1,180 mm high. Two standard modules fit along it with 50 mm spare, two across with 80 mm spare and three high with 280 mm spare, twelve in all on paper. The sterilisation car takes up part of that room, and the enquiry team states the usable module count in the quotation.

The Blackstone sheet gives up to 5.0 kW on a three-phase five-wire 380 V 50 Hz supply, roughly 8 A per phase. A series listing for the same design gives 3.5 kW and no figure for a built-in steam generator at this size, so the WF-1000DM depends on site steam. The enquiry team shares the quoted unit rating, and the circuit follows BS 7671 in the UK.

Site steam at 0.3 to 0.6 MPa, with up to 42 kg drawn per cycle, which sizes the boiler capacity, steam main and condensate return. Water arrives at 0.1 to 0.2 MPa, up to 200 kg per cycle, behind backflow protection, and the drain must take hot discharge. Compressed air at 0.4 to 0.7 MPa feeds the pneumatic door seal.

The crate weighs 1,680 kg, and a 1,950 mm cabinet is close to the clear height of many door openings before moving skates are added, so measure the route; never assume it. At 1,550 kg net weight on a 1,500 × 1,440 mm footprint, it loads the floor at about 720 kg per square metre, dry. The loading car needs a clear approach, and a competent person plans the lift into position under LOLER.

Class B belongs to EN 13060, and that standard covers sterilisers below 60 litres whose chambers cannot take a sterilisation module. With a 1,000-litre chamber, the WF-1000DM sits under EN 285. Ask for the manufacturer's EN 285 test results and build the validation around EN ISO 17665.

Great Britain's Pressure Systems Safety Regulations 2000 bring the vessel, door safety devices, steam supply and air system under a written scheme of examination drawn up by a competent person, with periodic examinations. Validation, Bowie-Dick and air leakage tests and steam quality checks follow HTM 01-01 Part C, with SHTM 01-01 Part C applying in Scotland. Medigear.uk can arrange installation, commissioning and service cover.

Series listings describe report processing and traceability so that each car load can be matched to its cycle record. That link is what lets a department trace a wet pack back to the programme and conditions that produced it. The enquiry team shares the record format with the programme list.

The WF-1000DM 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, in this capacity, should list EN 285, EN 61010-1, and EN 61010-2-040.
