Cool storehouses require stable temperature and humidity control equipment to preserve stored goods quality during continuous long term operation. Standard rooftop units struggle to maintain precise temperature and moisture levels, easily causing environmental fluctuation and affecting storage conditions. To meet the rigorous climate control demands of a cool storehouse project in China, IMMERSION ENERGY delivered a customized constant temperature and constant humidity packaged rooftop unit.
This packaged rooftop unit features 22kW cooling capacity and 82kW electric heating capacity, with 6kg/h humidifying capacity and R410A refrigerant. Fully compliant with local 3P/380V/50Hz power standards, it delivers stable temperature and humidity regulation, ensuring reliable and safe storage conditions throughout the year.

Cool storehouses operate continuously with strict requirements on stable temperature, precise humidity and long term equipment reliability. Ordinary air conditioning units cannot maintain consistent environmental control, easily causing temperature drift and humidity fluctuation that affect stored product quality.
IMMERSION ENERGY’s tailor made packaged rooftop unit is fully optimized for cool storehouse working conditions. Adopting constant temperature and constant humidity control technology with high efficiency R410A refrigeration, the unit achieves precise cooling and reliable electric heating. The integrated humidifying system maintains stable 6kg/h moisture output, perfectly adapting to the continuous environmental demands of storage facilities.
The unit is highly compatible with China’s local 3P/380V/50Hz power grid, running stably without additional power conversion devices. With optimized internal airflow and control structure, it maintains consistent rated performance, effectively preventing environmental instability risks and reducing long term operation and maintenance costs for the storehouse.
This successful deployment in China verifies IMMERSION ENERGY’s professional capability to customize constant temperature and humidity rooftop units for storage facilities, and proves the excellent environmental control precision, reliability and operational stability of our packaged HVAC systems under local power and climatic conditions. Leveraging mature HVAC R&D and manufacturing experience, IMMERSION ENERGY will continue optimizing system efficiency and reliability, providing professional and cost effective climate control solutions for global storage and cold chain projects.
