Features真空乾燥装置・真空ベーキング装置Vacuum Drying Oven/Vacuum Baking EquipmentDQ "Noa" Series■High vacuum ... Ultimate pressure: x10 1 PaIt's exhaust system is an oil-sealed rotary vacuum pump only, but the DQ Series produces apowerful vacuum. The DQ Series types provide clean heat treatment in a vacuum chamberwith exceedingly low leakage.■Effective exhaustMatching the valve and piping aperture diameters with the vacuum pump's suction port diameterallows for more effective and faster exhaust.■Measurement of vacuum degreeThe structure is equipped with a gauge port (φ15 mm) that allows the attachment of a Piranivacuum gauge sensor to confirm the vacuum degree (Pa value), a value that can't be read byBourdon-tube vacuum gauges.■Easy temperature controlThe controller automatically sets the ideal PID value for processing temperatures for easy,reliable temperature control inside the vacuum chamber.■Safety and Product Maintenance1 The temperature controller and the overheating prevention device each provide independentcomprehensive safety measures, including a self-diagnosis function and double overheatingprevention functions.2 To ensure safety, a protective cover made of clear resin overlays an observation windowdesigned for clear viewing. (No observation window is provided for high-temperature types inwhich temperatures exceed 200℃.)3 DQ-P (type with built-in pump) ... In addition to manual valves, this type features a built-inmain solenoid valve and pump leak solenoid valve. For example, in the event of a power failureduring operations, the main solenoid valve closes and blocks the vacuum chamber, while thepump leak valve opens to prevent pump oil backflow.■The standard used for the DQ Series is Max 200℃(external heating system), but high-temperaturetypes (internal heating) with specifications of Max 350℃, 450℃and 600℃are alsoavailable. The heaters are incorporated into the lower part of each shelf or affixed to the innerwalls of the chamber. In addition to performing high-temperature heating within the chamber,they reduce the time required to heat the chamber to processing temperatures and improvetemperature distributions within the chamber. To further meet client needs, custom models canbe designed and manufactured to implement automated operations.Specifications for DQ“Noa”SeriesPerformanceFunctionsExhaustsystemHeatingSafety devicesStandardsOptionsMaximum temperatureUltimate pressureOperation systemControl systemSetting method/Display methodSensorOverheating preventionCommon to both DQ-P/SDQ-P typeDQ-S typeHeaterLoad controlPower supplyCooling waterN2*We can manufacture custom models to specifications.200℃(350℃/450℃/600℃)x10 1 Pa (after bakeout at no-load normal operating temperature)ManualMicrocomputer used for PID control (auto-tuning function provided)Digital setting/Digital displayK thermocoupleIndependent double overheating prevention circuitsManual main valve, Leak/gas inlet valve, Bourdon-tube vacuum gauge,φ15 Gauge port, Leak/gas inlet, Vacuum pipingBelt-driven oil-sealed rotary vacuum pump (50 to 1500 L/min), Main solenoid valve, Pump leak solenoid valvePump connection portSpace heater (affixed to the outer surface of the vacuum chamber)Current outputEarth leakage breaker, Heater circuit/control circuit fuses, Double overheating prevention (suspension of heating,buzzer/lamp alarms, manual reset), Self-diagnosis function (setting values, temperature sensor, burnout)1φ100V AC, 1φor 3φ200V ACAt least 0.2 MPa (When the heating temperature exceeds 200℃)Use as required when the chamber is returned to atmospheric pressurePirani vacuum gauge, WS Series oil cleaner, Cold trap,Hermetic sealing, Programmable temperature control,Individual temperature control of internal heaters, Automatic operation system7
