Blackstone DGT-23A

Because it needs only a bench, a suitable circuit and distilled water, the DGT-23A fits rooms where plumbing in a steriliser is impractical. That includes satellite clinics, refurbished rooms and laboratory benches far from a sink, where routing water and drainage would be disruptive. Dental and medical treatment rooms, laboratories and hospital departments are the settings the manufacturer's distributors name, and a US distributor of this model sells it to nail and beauty salons. In every case,, the load must be solid, unwrappe,d, and steam-toleran;; lumened, wrappe,d, or porous items belong in a vacuum steriliser.

The 450 mm chamber depth leaves room for longer instruments such as specula and long forceps. A distributor's packing list includes three trays, which makes it simple to keep different materials apart within a load.

The evidence points to procedure as the deciding factor. Testing at 200 dental offices in San Luis Potosí, Mexico, found biological-indicator growth in 17% of 230 sterilisers, traced to mistakes with temperature, time, or pressure; unsupervised assistants; and poor maintenance. Routine monitoring changes that picture: a Saskatchewan quality assurance dataset of almost 199,000 tests found 0.2% failing. For a hand-filled steriliser, filling, loading, and draining are part of the procedure, and they belong in the practice's written protocol from the first cycle.

Health systems that buy through formal procurement, including the NHS, expect conformity evidence and a validation route, and public buyers elsewhere generally do the same. The conformity documentation those procurement routes require is issued by the manufacturer and shared by the enquiry team.

Installs Without a Plumber

With water poured in by hand and drained through a hose, the DGT-23A has no fixed water connection. No plumbing work or backflow arrangement is needed, and the water fittings regulations for plumbed equipment do not apply, so it can go wherever a bench and a circuit allow.

A Load the Electrician Can Size

The 2 kW rating is published, which turns electrical planning into simple arithmetic: about 9.1 A at 220 V and 18.2 A at 110 V. The electrician can size the circuit before delivery, which matters most on 110 V supplies where a standard 15 A circuit falls short.

Steam From an Internal Generator

Saturated steam comes from a generator built into the unit, and the manufacturer says it supplies that steam quickly. The generator feeds the chamber for every programme, so you don't need a separate steam source.

Shut-Offs for Water, Heat and Pressure

The controller stops heating when the water level falls too low to prevent dry heating, and it cuts in on over-temperature or over-pressure. Those four protections cover the failures a hand-filled generator is most exposed to, as long as you follow the filling routine.

Freight Planned Before Ordering

The Blackstone sheet gives the carton as 690 × 470 × 410 mm and 32 kg, about 0.13 m³. Buyers importing the unit can quote freight and arrange handling at the destination before placing the order.

Room for Longer Instruments

A 450 mm chamber leaves space for specula, long forceps and similar instruments, and a distributor's packing list includes three trays. Spreading a load across trays keeps materials apart and lets steam reach each surface.

Automatic Venting at Both Ends

Steam entering at the start pushes the cold air out automatically, the passive method a Class N design relies on, and the unit vents its own steam once sterilising ends. The buzzer then tells staff the cycle is over, with nothing to vent by hand.

A Connection Point for Validation

The manufacturer fits a standard test interface, giving the validation engineer a fixed place to connect test instruments. That point is used at installation and again at each periodic test.

A Rear Panel Laid Out for Service

The power inlet, a switch, and a recessed valve marked with a warning symbol sit together on the rear panel. Keeping the back of the unit reachable and unobstructed makes disconnection and servicing simple and keeps the area around the valve clear.

23-Litre Stainless Chamber

The chamber is stainless steel with a stainless sealing cover, measuring Ø250 × 450 mm on the Blackstone sheet and 452 mm deep in one distributor listing.

121 °C and 134 °C on Touch Buttons

Each temperature has its own selection on the touch panel. A distributor lists the holds as 20 minutes at 121 °C and 4 minutes at 134 °C.

Generator With Water-Level Protection

The built-in generator runs under low-water protection and anti-dry heating, so it stops heating when the water runs short.

Over-Temperature and Over-Pressure Cut-Outs

If either temperature or pressure passes its limit, the protection ends the cycle.

Pressure Vessel Ratings

The vessel works at up to 0.22 MPa and is designed for 0.25 MPa and 139 °C.

Automatic Air Discharge

Air is pushed out automatically as steam fills the chamber at the start of each cycle.

Exhaust, Buzzer and Automatic Stop

When the hold ends, the unit exhausts steam, sounds a buzzer, and stops automatically.

Standard Test Interface

A standard interface lets validation and periodic test instruments connect to the steriliser.

Front Gauge and Drain Valve

The series photographs show a mechanical pressure gauge beside the digital controls and a drain valve low on the front panel.

Wheel-Handle Door

The round door seals by turning a wheel handle, as shown in the series photographs.

Rear Valve Housing and Power Inlet

The DGT-23A photograph shows a recessed valve under a warning symbol, a power inlet and a switch on the rear panel.

Hand Filling With Distilled Water

Water for the generator is added by hand, and this model specifies distilled water.

2 kW in Two Mains Versions

The unit is offered for AC 110 V 60 Hz and AC 220 V 50 Hz supplies, rated at 2 kW in both.

Dimensions, Weight and Packing

Figures for the unit are 610 × 385 × 355 mm and 27 kg net on the Blackstone sheet and the manufacturer's listing. Packed, it measures 690 × 470 × 410 mm at 32 kg gross, while distributor listings give 600 × 400 × 350 mm and a 640 × 450 × 390 mm carton at 29 kg.

Distributor Packing List

One distributor ships the DGT-23A with three instrument trays, a tray rack, a drain hose, a spare door seal, protective gloves and the user manual.

The DGT-23A suits clinics, laboratories and salons that process solid, unwrapped instruments and want a 23-litre steriliser needing no plumbing, only a bench, distilled water and a suitable circuit. It is not suitable for handpieces, lumened, wrapped, or porous loads, or for sites that need printed cycle records. Before ordering, have an electrician provide a dedicated 2 kW circuit rated above 18 A on 110 V supplies, and book a competent person to prepare the written scheme and carry out validation. Medigear.uk lists the DGT-23A for business buyers worldwide and can arrange delivery, installation, commissioning, familiarisation and service cover. Before ordering, ask the enquiry team for the manufacturer's lead times, drying position and maximum load, the door-locking description, and the declaration of conformity.
