Wendler Inside Project – Hitachi VRF Air Conditioning System & Industrial Ventilation
Abontika HVAC Engineering successfully completed the Wendler Inside project, delivering a comprehensive HVAC and industrial ventilation solution for a high-ceiling commercial building. The project included office spaces, a 60,000 sq.ft warehouse and production areas, staff canteen, and critical utility rooms, all requiring advanced climate control and efficient ventilation.
Office Space – Hitachi VRF Air Conditioning System
For the office areas, a Hitachi VRF air conditioning system with ducted indoor units was installed to provide energy-efficient and reliable cooling throughout the high ceilings of approximately 20 feet.
The system was designed to ensure uniform air distribution, precise temperature control, and optimal indoor comfort. A fresh air ventilation system was also integrated to maintain indoor air quality while complementing the VRF system’s performance.
Key benefits of the Hitachi VRF air conditioning system in this project:
- Variable refrigerant flow technology for energy efficiency
- Multiple indoor units connected to a single outdoor unit
- Quiet operation suitable for office environments
- Flexible installation for high-ceiling spaces
Warehouse & Production Area Ventilation
The 60,000 sq.ft warehouse and production area required a robust industrial ventilation solution. Industrial ventilation fans were installed throughout to maintain airflow, reduce heat accumulation, and ensure a safe working environment.
The fans were high-capacity units rated at approximately 52,000 CMH, providing sufficient ventilation for large spaces while complementing the office VRF system. Proper airflow and temperature control help in maintaining product quality and staff comfort in the production areas.
Canteen & Utility Rooms Ventilation
For the staff canteen, a through-duct ventilation system was installed to remove heat and odors efficiently, providing a comfortable environment for employees.
Critical utility areas, including the substation and generator rooms, were equipped with high-capacity ventilation fans, ensuring optimal airflow and safe operation of electrical and mechanical equipment.
