BIDA as a professional manufacturer focusing on the R&D, production and supply of HVLS industrial fans, we have been deeply engaged in the Southeast Asian market for many years. We have a thorough understanding of the local tropical hot and humid climate characteristics and the actual needs of primary and secondary school education scenarios, as well as the voltage standards of various countries and local requirements for campus venues. HVLS (High Volume Low Speed) ceiling fans, with their core advantages of large coverage, energy saving and high efficiency, and quiet comfort, have become the preferred ventilation and cooling solution for gymnasiums and auditoriums of primary and secondary schools in Southeast Asia. They effectively solve the environmental problems caused by large venue space and dense personnel, help the smooth development of campus activities, and adapt to the diverse needs of campuses in Thailand, Vietnam, Indonesia, Malaysia and other countries.

I. Application Environment of HVLS Ceiling Fan (Adapted to Primary and Secondary School Scenarios in Southeast Asia)

• Adapted to the tropical hot and humid climate in Southeast Asia. Aiming at the characteristics of perennial high temperature and humidity (annual average temperature 25-30℃, humidity 70%-90%) in countries such as Thailand, Vietnam, Indonesia and Malaysia, it can quickly alleviate the stuffiness and humidity in the venue, improve indoor comfort, and meet the rigid demand for year-round high temperature in the region.
• Adapted to the core scenario of primary and secondary school gymnasiums, including basketball, badminton and other sports training, school sports meeting held, physical education teaching, etc. It conforms to the design specifications of physical education venues in primary and secondary schools, solves the pain point of poor air circulation in large and tall venues, avoids stuffiness and discomfort of students during exercise, and ensures the safe development of physical education teaching and activities.
• Adapted to the scenario of primary and secondary school auditoriums, meeting the needs of dense personnel activities such as opening ceremonies, cultural performances, parent-teacher meetings, and campus lectures. It balances ventilation and cooling with a quiet environment, adapts to the characteristics of dense personnel and diverse activity types on campus, and ensures the smooth development of various campus collective activities.
• Adapted to the architectural characteristics of primary and secondary school venues in Southeast Asia. Aiming at the current situation that most campus venues have high floor height (4-10 meters), open space and insufficient window ratio (the window-to-floor ratio of some venues is less than 10%), it can be installed and used without large-scale renovation. At the same time, it adapts to the simple and practical architectural style of local campus venues, and conforms to the actual situation of primary and secondary schools with limited budget and inconvenient renovation.

II. Usage Effect of HVLS Ceiling Fan (Core Advantages Highlighted)

• Efficient cooling and ventilation, with a sensible temperature reduction of 5-8℃. A single fan can cover 1500-2000 square meters, quickly promote indoor air circulation, eliminate temperature stratification, avoid heat accumulation on the roof, make the temperature in all areas of the venue uniform, alleviate the discomfort caused by damp heat, adapt to the perennial hot and humid climate characteristics of Southeast Asia, and improve the comfort of teachers and students’ activities.
• Energy saving and cost reduction are more economical. The power of a single unit is only 0.75-1.5kW, which is more than 80% energy-saving compared with traditional air conditioners. It conforms to the current situation of high electricity costs in various Southeast Asian countries (for example, the small commercial electricity rate in Thailand is about 3.9 baht per kilowatt-hour), greatly reducing campus operation expenses, adapting to the needs of primary and secondary schools with limited budget and the need to control expenditure, and helping campuses save operation and maintenance costs.
• Quiet operation without interference. The operating noise is less than 50 decibels, which meets the requirements of a quiet campus environment. It does not affect the normal development of sports training, cultural performances, lectures and other activities, and ensures the communication and learning experience of teachers and students, adapting to the core demand of campuses for a quiet environment.
• Moisture-proof and mildew-proof to protect the venue. It effectively accelerates the discharge of indoor moisture, reduces the moisture regain and mildew growth on walls and floors, protects venue facilities and sports equipment, extends their service life, reduces campus maintenance costs (referring to the annual maintenance cost standard of primary and secondary schools), and conforms to the maintenance needs of campus venues in the high-humidity environment of Southeast Asia.
• Safe, convenient and easy to maintain. It adopts anti-fall and anti-leakage design, adapts to campus safety standards, and at the same time conforms to the electrical safety specifications of various Southeast Asian countries. No frequent maintenance is required after installation. The manufacturer provides perfect after-sales service and can provide timely technical support according to the needs of local campuses, reducing the burden of campus management.

III. Installation Site Requirements for HVLS Ceiling Fan (Simple Adaptation, No Large-Scale Renovation Required)

• Floor height requirement: The net height of the venue shall not be less than 4 meters, and the lowest end of the fan blade shall be not less than 3.5 meters from the ground, so as to ensure the safety of teachers and students’ activities and maximize the ventilation effect. It adapts to the generally high floor height characteristics of gymnasiums and auditoriums in primary and secondary schools in Southeast Asia, taking into account both safety and practicality.
• Load-bearing requirement: The ceiling of the installation area shall have sufficient load-bearing capacity, with concrete beams ≥200kg/㎡ and steel structure beams ≥150kg/㎡. A structural calculation report shall be provided to ensure stable installation, conform to the safety specifications of primary and secondary school architectural design, and ensure the safety of teachers and students’ activities on campus.
• Space requirement: There shall be no obstacles (such as lamps, pipelines, bridge frames, etc.) within 1.5 times the rotating radius of the fan blade to avoid interfering with the operation of the fan. At the same time, reasonable installation and maintenance space shall be reserved. It adapts to the simple layout characteristics of primary and secondary school venues in Southeast Asia, without the need to adjust the existing facilities of the venue additionally.
• Power supply requirement: Adapt to the voltage standards of various Southeast Asian countries. Power supply adaptation schemes can be customized according to the needs of Thailand (220V, 50Hz), Malaysia (230-240V, 50Hz), Vietnam (220V, 50Hz), Indonesia (220V/110V, 50Hz) and other countries. Normally, a 380V±10% three-phase five-wire power supply is required, with a grounding resistance ≤4Ω and a distribution box capacity ≥5kVA to meet the stable operation needs of the fan.
• Environmental requirement: The installation environment shall avoid direct contact with water sources, with relative humidity ≤85% (no condensation). The on-site wind speed during installation shall be ≤5m/s, and construction is prohibited in thunderstorm weather. It adapts to the hot and humid climate with frequent thunderstorms in Southeast Asia, ensuring installation safety and the service life of the fan.
