The Yamato DP-63C is a 216 L floor-type large-capacity vacuum drying oven — the larger of the DP43C/63C pair (216 L vs 91 L). It dries by decompressed-chamber direct heating: reducing chamber pressure to as low as 0.1 kPa (1 Torr) lowers the boiling point of moisture and solvents so they evaporate gently at low temperature. A program operation function (16 segments), a green-LED PID controller, and an integrated bottom cabinet that stores the vacuum pump make it a space-efficient floor unit. on a 220V single-phase supply, it suits larger-part vacuum drying, high-volume bulk solvent removal, and production degassing where the 91 L DP-43C runs short on chamber volume.
Its smaller sister is DP-43C (91 L); step up to the DP83C/104C series (512 L / 1000 L).

Application Profile
Larger-part and high-volume vacuum drying. The 216 L chamber and 600 mm-cube interior accept large parts and high-volume batches; decompressed direct heating dries them gently at 40–200 °C under reduced pressure.
Bulk solvent removal. Reduced pressure lowers solvent boiling points so residual solvents are stripped from powders, films, and assembled parts at low temperature. The 16-segment program operation runs a defined multi-step drying schedule.
Production degassing and outgassing. Deep vacuum (to 1 Torr) drives dissolved gases and volatiles out of resins, adhesives, and cast materials before curing or measurement.
Moisture-sensitive preparation at scale. Bound and surface moisture is removed from hygroscopic materials and larger assemblies before further processing, without oxidative exposure.
Space-limited labs. The vacuum pump stores in the bottom cabinet, keeping the footprint compact for a floor-standing large-capacity oven.
Design Architecture
The DP-63C dries by decompressed-chamber direct heating: a 3.15 kW mica heater warms the stainless chamber while an external vacuum pump evacuates it through the NW25 exhaust flange to as low as 0.1 kPa (1 Torr), read on a Bourdon-tube gauge (0 ~ -0.1 MPa). An improved exhaust system significantly shortens vacuum-reaching time, and the pump can be stored in the bottom cabinet with quick-connect piping for easy maintenance.
Control. A microprocessor PID controller holds setpoint to ±1.0 °C at 200 °C across the 40–200 °C range, with green-LED digital display and ▲/▼ digital setting. Operation modes include fixed-temperature, quick auto-stop, auto-stop, auto-start, and 16-segment program operation; a calendar timer and integration-time functions are included. A K-thermocouple double sensor and triac zero-cross heater control govern the heat circuit.
Chamber and viewing. The 600 × 600 × 600 mm interior provides 4 shelf-support steps at 140 mm pitch with 2 perforated stainless-steel shelves. A large tempered-glass + polycarbonate observation window with protective cover allows monitoring under vacuum.
Safety. Self-diagnostic functions (sensor, heater, triac, automatic overheating prevention), an independent overheating-prevention circuit, key-lock, and an electric-leakage breaker. Never use in a flammable or explosive gas atmosphere, and never process explosive or flammable material. High-temperature components — observe burn-hazard cautions.
Frequently Asked Questions
How low a vacuum does the DP-63C reach? Down to 0.1 kPa (1 Torr), across an operating pressure range of 101 to 0.1 kPa (760 to 1 Torr).
What is the chamber capacity and temperature range? 216 L (a 600 mm-cube interior), operating 40 to 200 °C with ±1.0 °C control accuracy at 200 °C.
Does the DP-63C include a vacuum pump? No — pair it with a pump such as the GLD202BB oil-sealed rotary vacuum pump (and the CA301 cooling trap for solvent-laden loads). The pump can be stored in the oven's bottom cabinet.
What power does the DP-63C require? 220V single-phase, 15 A, 50/60 Hz.
Can it run automated drying cycles? Yes — a 16-segment program operation function plus fixed-temperature, quick auto-stop, auto-stop, and auto-start modes.
Ordering & Configuration
Included: 2 perforated stainless-steel shelves.
Pair with a vacuum pump. Yamato lists the GLD202BB oil-sealed rotary vacuum pump with rubber- or SUS-hose kit (115V or 220V) and the CA301 cooling trap for solvent-laden loads. Factory-installed options include an N2 gas introduction device (30 L/min) and a vacuum-pump switch — specify at order.
Confirm electrical supply. The DP-63C is 220V single-phase, 15A. Confirm supply and circuit at order.
Plan floor space and installation. At 820 × 819 × 1650 mm external and ~290 kg, this is a floor-standing unit — confirm room access, floor loading, and service clearance at order.
Confirm application fit. Verify sample chemistry, target temperature/vacuum, batch/part size versus the 216 L chamber, and whether the 91 L DP-43C or the larger DP83C/104C series is the better match.
Request a quote for pricing, vacuum-pump and cooling-trap pairing, factory-installed options, electrical/installation planning, lead time, and warranty. Warranty per Yamato standard capital-equipment terms — confirm at quote.
