According to the search results, the following areas in Indonesia are particularly suitable for deploying ERV (energy recovery ventilation) systems, 

mainly based on industrial density, climate conditions and infrastructure requirements:

I. Core industrial areas ‌

Jakarta and satellite cities (such as Cikarang) ‌

Cikarang in West Java is Indonesia's core industrial base, gathering a large number of electronic and food processing plants and storage centers, 

with high requirements for indoor air quality and temperature and humidity control. ERV systems can effectively reduce air conditioning loads and ensure ventilation efficiency.

Cigante Modern Industrial Park (68 kilometers from Jakarta) has become an ideal area for the application of ventilation equipment with its perfect infrastructure 

(stable power and logistics network).

Surabaya (East Java) ‌

As the second largest economic center in Indonesia, cold chain logistics facilities are concentrated (accounting for more than 30% of the country's cold storage resources), 

and ventilation accounts for a significant proportion of the energy consumption of cold storage operations. ERV can achieve energy saving in coordination with the refrigeration system.

II. Emerging industrial and resource development zones ‌

Batang Integrated Industrial Park (Central Java) ‌

The government focuses on developing parks to attract manufacturing investment. The factories in the park need to cope with high temperature and high humidity climate. 

The ERV system can optimize the production environment and reduce energy consumption costs.

North Maluku Province (Ternate, etc.) ‌

A historical port city that is developing fishery processing and mining industries. Due to the unstable power supply on remote islands, the low energy consumption characteristics of 

ERV can alleviate the pressure on the power grid.

3. High heat load cities and tourist areas ‌

Yogyakarta (Central Java Province) ‌

The rapid development of tourism has led to the construction of hotels and commercial centers. The local average annual temperature is above 28°C, and ERV can solve the contradiction 

between ventilation and air conditioning energy consumption in densely packed buildings.

South Sulawesi Province ‌

Industrial expansion and the commissioning of the first wind power plant (75 MW) reflect the need for energy upgrades. ERV is suitable for deployment in new factories and public facilities 

to achieve energy recycling.

Adaptation scenarios and needs ‌

Regional type ‌ ‌ERV application advantages ‌

Industrial plant ‌ Reduce 40%-60% cold storage energy consumption (Jakarta, Surabaya); offset the heat load of electronic workshops (Cikarang)

Commercial complex ‌ Solve the ventilation bottleneck of high-density buildings such as Yogyakarta and Bali, and improve comfort

Regions with unstable power supply ‌ Islands such as North Maluku rely on low-power equipment, and ERV is more adaptable to power-limited environments than traditional air conditioners

Note ‌: The demand for energy-saving ventilation equipment in the Indonesian market has increased by 10.8% (2024 data). Chinese brands such as KALE FANS and OPTFANS have already 

deployed in the local area, and their ERV products are adapted to high temperature, high humidity and industrial environments.
