BB-1 fiberglass louver box

The fiberglass louver box consists of a louver box body (and a bracket), all made of high-quality fiberglass. The design principles and comparative measurements show that it not only overcomes the disadvantages of the original wooden louver box, such as easy decay, cracking, and short service life, but also significantly improves the comprehensive performance of ventilation, insulation, radiation protection, and wind and rain prevention. It meets the technical requirements proposed in the "Guidelines for Meteorological Instruments and Observation Methods" issued by the World Meteorological Organization and the "zba4700-85" professional standard for louver boxes issued by the China Meteorological Administration.

Technical Specifications:

1. Dimensions: 720 (length) x 780 (width) x 880 (height) (mm)

2. Box volume: 470 (length) x 465 (width) x 615 (height) (mm)

3. Weight: 35kg

4. Bracket: Height: 1230 (mm)

5. Weight: 14kg

6. Installation: Installation hole 3- φ 13 on the disc bottom plate

7. Circumferential diameter: divided equally into 4, 10, and 120 degrees

8. Overall height: 2095mm

Product advantages:

1. The geometric dimensions and shape are similar to the original wooden large louver box

2. The material is made of fiberglass with low thermal conductivity, small heat capacity, corrosion resistance, crack resistance, and strong anti radiation force. The fiberglass louver box does not rot in rainy, acid rain, and humid environments, and does not crack under dry and scorching sun, with a long service life

3. The structure adopts an inverted "v" - shaped integral frame layered fastening structure, which is sturdy and will not loosen. It can ensure the normal exchange of gas inside and outside the box, and effectively prevent rain and snow from blowing into the box. The upper cover plate has been changed to an inverted "funnel-shaped" ventilation cover. In clear and windless conditions with rapid changes in the external environment, the gas inside and outside the box can quickly exchange, and the internal and external environments quickly converge. This overcomes the disadvantage of lagging wooden louver boxes and makes the observation data more accurate and representative

4. Due to significant differences in wood quality across different regions, the representativeness of performance and data for wooden louver boxes varies. BB-1 fiberglass louver boxes can overcome errors caused by materials

5. Beautiful and elegant appearance, with a snow-white and smooth surface, no need for painting or care, and a service life of over fifteen years. High cost performance ratio, cost-effective

6. The bracket is made of fiberglass material, which is sturdy, lightweight, and aesthetically pleasing
