DY <Wing> Series

■DY-P type: Fully-automatic high-temperature vacuum drying and baking
DY-MP type: Features a pump for a greater exhaust volumes at dramatically increased speeds

The DY Series fully-automatic vacuum drying and baking equipment has been designed and manufactured as production machinery. In addition to meeting requirements for production line reliability, safety, and operability, this equipment enables high-temperature processing up to 650℃.
The DY-P and DY-MP types incorporate different pumps and offer different ultimate pressures and exhaust speeds. Select the type that best meets your needs.

DY-P type


DY-P type
The exhaust system incorporates a stand-alone oil-sealed rotary vacuum pump. The ultimate pressure is x101Pa.

DY-MP type
The exhaust system incorporates an oil-sealed rotary vacuum pump with a mechanical booster for increased exhaust speed. The ultimate pressure is x100 Pa, an order of magnitude higher than the DY-P type. The DY-MP type is ideal for large-quantity processing of workpieces that involve large gas volumes.

Heating mechanism
To achieve high temperatures inside the vacuum chamber, the system incorporates an internal heating system in which sheath micro-heaters attached to the underside of each shelf board serve as heating sources. Depending on the type of workpiece, heaters can also be attached to the inner wall surfaces of the chamber. With either system, compared to external heating systems, our internal heating system reduces the time required to heat the chamber to the specified temperature and improves temperature distributions within the chamber.

Heating control
PID control is performed by individual temperature controllers provided for each of the heaters installed in the chamber, thereby ensuring accurate, reliable temperature control. Additionally, programmable controllers can be used to specify heating patterns.

The DY Series types are easy to use and can be operated by anyone. Simply press the Start button to turn on the system and activate the sequencer program for automatic control of functions including vacuum exhaust, heating, and valve opening and closing. The device system configuration and On/Off status of each of the devices are displayed on the graphic panel to enable easy confirmation of operating status. Various interlock functions are provided to prevent erroneous operations at each separate stage.

In the event of an equipment malfunction during automatic operations, the system either halts all operations or specific functions, depending on the type of malfunction (a drop in cooling water amount or air pressure, overheating, and so forth), and uses the lamps on the graphic panel to indicate the type of malfunction. The system also implements a comprehensive range of safeguards. For example, in the event of a power failure, the main valve closes to maintain pressures in the vacuum heating chamber (to prevent oxidation of the workpieces caused by atmospheric leaks), while the pump leak valve opens to prevent backflow of the pump oil.

Optional forced cooling function dramatically reduces processing times
Since vacuums serve as superior insulators, heat dissipation can take a very long time. Even when the heaters are turned off following heat treatment, it takes a long time for temperatures to drop to around 50oC, at which workpieces can be removed. The optional forced cooling function dramatically reduces the time required for temperatures to drop, thereby significantly reducing total processing times.


The DY Series types are used primarily for a wide range of production line processes, including vacuum baking of components for precision devices, components for electrical/electronic devices, electronic materials, metals, ceramics, and laser device components and for vacuum drying in the food, pharmaceutical, and chemical industries.
