Steam and air conditioning supply

NACE v2.1 Code: D35.3

About steam and air conditioning supply

NACE code 35.3 covers the steam and air conditioning supply industry, which plays a crucial role in providing essential utilities for various sectors of the economy. This industry is responsible for the generation, collection, and distribution of steam and hot water, as well as the production and distribution of chilled air for cooling purposes. Its services are vital for maintaining comfortable and efficient working environments in commercial, industrial, and residential settings.

Production process

The main production techniques used in the steam and air conditioning supply industry involve the generation of steam or chilled air through the use of boilers, chillers, and other specialized equipment. Steam is typically produced by heating water in boilers, which can be fueled by various sources such as natural gas, coal, or renewable energy. The steam is then distributed through a network of pipes to end-users. Similarly, chilled air is produced by refrigeration systems, which use compressors, condensers, and evaporators to remove heat from the air, and then distribute the cooled air through ductwork.

Production inputs

The key inputs required for the steam and air conditioning supply industry include fuel sources (such as natural gas, coal, or renewable energy), water for steam generation, and specialized equipment like boilers, chillers, and distribution systems. Additionally, the industry relies on skilled technicians and engineers to operate and maintain the production and distribution infrastructure.

Production outputs

The main outputs of the steam and air conditioning supply industry are the provision of steam, hot water, and chilled air to various end-users. These outputs are consumed by a wide range of industries, including 36.0 Water collection, treatment and supply, 41.2 Construction of residential and non-residential buildings, 46.7 Wholesale trade of other machinery, equipment and supplies, and 86.1 Hospital activities, among others. The steam and air conditioning supply industry plays a crucial role in supporting the efficient and comfortable operation of these industries.
