The stationary heat exchanger industry (HVAC)
HVAC (heating, ventilation and air conditioning) includes systems for heating and cooling, for instance in private houses, commercial premises, and industrial buildings. Stationary heat exchangers have a broad group of end users in industries such as the agricultural sector, retail, healthcare, manufacturing and property. Underlying growth factors for heat exchangers in HVAC, regardless of type, is construction investment, new regulations on energy efficiency, climate changes and economic growth. Brazed aluminium heat exchangers account for only a small share of the total market. Gränges is both a supplier of brazed and mechanically- assembled aluminium heat exchangers, with the strongest position in the Americas with close to 10 per cent market share.
Other end customer markets
Aluminium foil provides a complete barrier to light, oxygen, moisture, and bacteria. These properties make it ideal for food cartons and pouches. Semi-rigid containers are among the most versatile of all types of packaging and are widely used for pre-packaged foods, easily withstanding great differences in temperature from freezing to heating.
Another end market in North America is materials for transformers. A transformer is an electrical device used to increase or decrease the alternating voltages in electric power applications. It consists of two or more coils called windings, which are wrapped around a core. In North America, aluminium is becoming more common as winding material in distribution transformers, while copper is more common for large power transformers. Aluminium has significant cost and weight advantages over copper. The markets for semi-rigid containers and for transformer windings made in aluminium are expected to show stable annual growth.
