Efficient Climate Control

HDPE PCM Spheres are innovative thermal batteries designed for use in low-temperature and low-pressure water-based buffer tanks. Crafted from high-quality HDPE, these spheres serve as storage units for thermal energy. Additionally, they can be filled with Pluss savE® PCM, which includes organic materials and hydrated salts. This feature provides exceptional versatility and adaptability, making them suitable for a wide range of applications.

Increasing Thermal Energy Storage Capacity

Chilling HVAC systems often struggle to store cold energy efficiently. This inefficiency results in the need for large buffer tanks in inconvenient spaces such as cellars or next to commercial buildings. Consequently, there is a significant risk of space loss, high energy consumption, and overall inefficiency, making the current approach unsustainable.

However, HDPE PCM Spheres provide a promising solution to these challenges. These spheres have the capability to store more latent heat than a water-filled buffer tank alone. By seamlessly incorporating these spheres into chilling HVAC systems, more energy can be stored without the need to increase the size of the buffer tanks. The innovative approach of HDPE PCM optimizes space and ensures efficient cold energy storage, thereby making a valuable contribution to sustainability.


Efficient Cold Storage: HDPE PCM Spheres efficiently store cold energy during off-peak hours or when excess cooling is available. This optimizes energy consumption, resulting in cost savings and a reduced environmental impact.

Versatile Compatibility: These spheres can be paired with various PCM materials, making them compatible with a wide range of cooling applications in commercial and residential HVAC systems.

Durable and Reliable: Crafted from high-quality HDPE, these spheres offer durability and reliability in cold storage and cooling. They deliver long-lasting performance.

Enhanced System Performance: By reducing the workload on the cooling system and extending its lifespan, HDPE PCM Spheres enhance the overall performance of the system.

Partners using this solution

Thermal Energy Storage (TES) is a proven, efficient, and cost-effective method for delivering energy to chill air. By creating and storing energy during off-peak periods, TES spreads the energy requirement for air cooling across 24 hours, resulting in significant cost and capacity benefits.

Crystal Air Ireland utilizes Pluss PCM spheres to bridge the gap between energy storage and usage within HVAC systems. PCM Thermal Energy Storage schemes, offering full or partial storage capacity, typically recoup costs within three years.
