Heat Curtain

Problems and Causes

The oven is an equipment that uses heat processing to physically or chemically transform materials or products. Temperature is a critical factor directly affecting the quality of the workpiece, thus necessitating precise and consistent temperature control. However, heat from the oven significantly impacts the surrounding work area due to high-temperature heat radiating from the oven surface. In this production line, there are 12 ovens operating simultaneously, causing heat accumulation and extremely high temperatures in the work area. This issue greatly affects work efficiency, employee health, and safety, requiring urgent resolution.

Improvement Method

When NTI identified the problem, they conducted an on-site survey using thermal imaging cameras at multiple positions. They discovered that some oven surface temperatures reached up to 123 degrees Celsius, with an average room temperature of 44 degrees Celsius. Based on this data, NTI initially recommended reducing heat radiation by installing removable thermal insulation around the oven surfaces. However, due to the client’s various limitations, including budget constraints, the client requested alternative methods to reduce heat in the worker’s area.

NTI proposed installing a heat curtain using high-density insulation materials. This solution effectively addressed the client’s limitations because the heat curtain offers flexibility in installation and modification. It can be opened and closed quickly, saves installation space, and efficiently mitigates heat radiation affecting employees in the work area. After installation, the average room temperature was reduced to 34 degrees
