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. They can be filled with Pluss savE® PCM, which includes Organic Materials and Hydrated Salts, they offer exceptional versatility and adaptability for a wide range of applications.

Increasing Thermal Energy Storage Capacity

Chilling HVAC systems often struggle to store cold energy efficiently. This results in the need for large buffertanks in inconvenient spaces like cellars or next to commercial buildings. Which will lead to space loss, high energy consumption, and inefficiency, which is unsustainable.

However, HDPE PCM Spheres offer a solution. These spheres can store more latent heat than a water-filled buffer tank alone. By incorporating these spheres into chilling HVAC systems, more energy can be stored without increasing the size of the buffertanks. HDPE PCM’s innovative approach optimizes space and ensures efficient cold energy storage, contributing 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.

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. For more information, visit https://www.crystalair.ie/.
