When we sourced the DT638B for our chain, the thermostatic water heating was the feature that sealed it — no more patients flinching form cold water during cleanings, and the 0.2-0.4 MPa water presure range is tight enough for consistent spittoon flushing without hammering the lines.
We run three of these in ortho, and the 5-slot tool holder on the main table actually simplifies setups: 3 handpiece tubings, the three-way syringe, and one open slot for a scaler or curing light, though you'll want to confirm whether your handpieces use 2-hole or 4-hole connections since that's optional at order.
150cm by 110cm by 125cm is about what you'd expect for a mid-range chair, but the wooden case packaing meant zero damage on the shipping dock — we usually have stock in 20 days or so, but check lead time if you're in a rush.
electric lift with three memory positions is better than most chairs at this price point for positioning kids and adults quickly, but don't expect it to handle bariatric patients well — the metal frame is solid but the lift mechanism has a practical limit around 150 kg or so.
Actually, the PU leather option is easier to wipe down between patients than real leather, and the adjustable LED light has decent color rendering for composite work, though we swapped the default bulb on one unit for a warmer spectrum — the specs don't mention that, but it's a common tweak.
ISO and CE certs are standard, but the 1-year warranty on Chinese-made units is about average, and we've had no major issues across 8 units in 18 months — the rotatable ceramic spittoon is a nice touch for left-handed operators.
Both are built into the unit. The LED film viewer is mounted on the arm, and the thermostatic water heating system is part of the standard water supply setup — no extra modules needed.
The 2-hole setup works with older air-driven handpieces, while 4-hole supports newer ones with separate water spray. You choose one at ordering — it's not field-swappable, so let us know your preference upfront.
Yes, the metal frame has an anti-corrosion coating, so it holds up fine in high-humidity settings. Still, we recommend keeping the room ventilated to extend the life of all components.
Real leather costs a bit more, but for high-traffic clinics, PU is actually more durable and easier to clean. Both are comfortable, so it's more about budget and maintenance preference.
Yes, we include both ISO and CE certificates in the wooden case packaging. You'll get paper copies, and we can also email digital versions if you need them for local registration.
