BioPCMTM is the trade name for our family of proprietary bio-based phase change materials. When used in buildings they reduce cooling loads and HVAC energy consumption while enhancing the building’s comfort level.
Phase change materials “PCMs” use a basic nature of physics, the absorbing or releasing heat when matter changes from one state to another, to aid in thermal storage. When you warm up a solid material, its temperature rises steadily until it nears its melting point. Then it absorbs a significant amount of heat, but the material does not get warmer, until it fully melts. The process of changing phase from solid to liquid absorbs an enormous amount of energy comparatively to when the material’s temperature is changing in either its liquid or solid state.
When you cool down and freeze a liquid, the same process happens in reverse, the temperature remains at the freezing temperature until a significant amount of heat is removed, releasing stored energy and allowing it to freeze (change phase from liquid to solid). This physical interaction with the building environment is beneficial by absorbing excess heat and cooling the space and then releasing this stored heat back at a later time as the temperature drops below the product’s Q factor/desired temperature.
BioPCMTM is available a variety of melting points or “Q factor”: 73ºF (22.8ºC), 76ºF (24.4ºC), 79F (26.1ºC), or 84ºF (29ºC). The ENRG Blanket product line is available in a variety of different Btu per square foot loadings or “M” value’s.
ENRG Blanket can be configured to meet Class A or C fire ratings, and/or to meet Class I, II or III perm ratings. Additionally, ENRG Blanket is available in a Class A Plenum rating.
We manufacture BioPCMTM in North Carolina from rapidly renewable and sustainably harvested non-food palm oil byproducts as well as other rapidly renewable plant materials including coconut and soy.
BioPCMTM and our ENRG Blanket meet the provisions of the buy American act.
