Crystal T- Pak Cassettes

By Crystal Air PCM, Thursday, 8th September 2016 | 0 comments

The Crystal Air PCM Thermal Energy Storage solutions may use either T-Paks or Spheres to accommodate the phase change material within the overall storage arrangement. The phase change material is supplied encapsulated in specially designed triple sealed HDPE containers . In the case of the T-Paks the containers are designed to allow the creation of a battery effect in water and air systems for thermal storage within the temperature range of -33 deg C to a maximum of 89 deg C.

The T-Pak , as per below, is a fully sealed HDPE cassette containing the phase change material. The containers are designed to allow stacking in battery format within the overall thermal energy storage tank up to a maximum height of 2,500mm. The cassette  design allows for a small gap between each cassette to ensure for water flow between and around the cassettes to allow for full thermal transfer in either the charging or discharging mode.

T-Paks Thermal Energy Storage Options

The options for storage characteristics are extensive with the use of T-Pak cassettes both in terms of temperature and storage type. This is primarily due to the cassette design and the degree of its flexibility for both conditions. Thermal Energy Stores can be accommodated with the following tank arrangements options:

                        Underground concrete tanks

                        Above or below ground steel horizontal cylindrical tanks.

                        Sectional pre-insulated GRP storage tanks.

The final selection of the storage arrangement will need to take into consideration the following requirements:

The storage tank dimensions should be generally be in line with a 4 ; 1 ( length by width) and to conform to the maximum stacking height for the cassettes of 2,500mm. The overall tank storage capacity must include a 30% additional allowance to accommodate the internal chilled water flow requirements. The storage tanks can be either pressurised or atmospheric type for chilled water systems subject to the specific installation requirements.
