Hot wall tank furnace in clean area

The application of aseptic room has higher requirements for the selected structure of electric furnace. If the whole electric furnace is placed in the sterile room, the environment of the sterile room shall not be obviously polluted. In particular, ensure that particulate contamination is minimized.

Select the required electric furnace according to the requirements of various special applications. In many cases, a circulating air furnace is required to ensure the required temperature uniformity at low temperatures. Many electric radiant heating furnaces have also been used in higher temperature applications.

Installation of electric furnace in sterile room if the whole electric furnace is to be placed in the sterile room, it is very important to protect the furnace, furnace shell and control device from erosion. The surface must be easy to clean. A seal is provided between the furnace and the rear insulation layer. If necessary, the cleanliness level can be improved by additional devices, such as fresh air filters or air circulation in electric furnaces. It is recommended that the switchgear and furnace control devices be installed outside the sterile room.

The electric furnace is installed in the general work area. The electric furnace is loaded from the sterile room. In order to improve the quality of the sterile room, a simple installation method can be adopted: install the electric furnace in the general work area and load from the sterile room at the same time.

In this way, the occupation of high-cost storage space in the sterile room can be minimized. The front and hearth of electric furnace in sterile room shall be designed to be easy to clean. With this configuration, the highest level of sterile room can be achieved.

As a gate furnace, it is installed between the general work area and the sterile room. In many cases, the logistics between the general work area and the sterile room can be optimized in a simple way. For this purpose, a gate furnace can be used, one of which is located in the general working area and the other in the sterile room. The furnace and the side facing the sterile room shall be designed to minimize particulate contamination.

The type hot wall tank furnace with charging rack is used for heat treatment of glass under protective gas. The furnace is installed in the gray room with charging door in the pure room.

On the basis of basic furnace type, we can also customize special furnace type for superior process equipment. We can find the best process optimization scheme for you no matter the operation under vacuum or protective atmosphere, innovative control technology or automation, or the temperature, specification, length and performance of tank furnace.
