Smart resin insulated flush door for low-temperature equipment rooms.

The entrance and exit of a clean room with lowered temperature requires insulated doors. The DIR40, with all frame materials made of synthetic resin, maintains the appearance of an aluminum flush door while reducing condensation phenomena on the door body and outer frame caused by thermal conduction. The interior of the door is a combination of a resin frame and styrene foam, making it very lightweight and capable of handling certain chemicals that metal flush doors cannot accommodate.

In clean rooms and various testing rooms, the "observation windows" and "entrance doors" installed as equipment require various functions (such as airtightness and thermal insulation) that differ from standard architectural fittings. Sanwise Corporation develops, manufactures, and sells such specialized fittings for equipment. From small inspection openings to large doors for the entry and exit of machinery, sizes vary, and functions range from static electricity prevention to thermal insulation and high airtightness. Each item is custom-made to meet the specific requests of our customers. We respond promptly to inquiries and quote requests, so please feel free to consult with us!
