A Guide to Industrial HVAC Systems

Temperature Controlled Environments

HVAC stands for heating, ventilation and air conditioning system. The purpose of a HVAC systems is to control the environment which it is in, this is done through the control of temperature either by heating or cooling. HVAC systems also have the ability to control things such as humidity level as they can control the movement and distribution of air inside the room. It is important when installing a HVAC system that you choose the best one for you in order for it to be energy efficient and to serve its purpose.


There are a number of different heating systems which are available to you, all of which are suited to different applications. For industrial purposes the choices would generally include direct and indirect heaters, radiant heaters and boiler hire services.

Electric Heaters

Electric heaters are available in a variety of sizes and heating capabilities which is why they are generally one of the most popular choices. From smaller electric radiators which are great for domestic use, to industrial 3-phase blowers which are perfect for industrial applications.

Direct Fuel Heaters

Direct fuel heaters are ideal for the heating of various workplaces, especially large open spaces such as warehouses. They offer a high volume of heating capacity which makes them great for industrial applications. Multiple can be used to heat large spaces if required. Direct fuel heaters must be placed in a ventilated area as they do add moisture to the air as they heat the space.

Indirect Fuel Heaters

Indirect fuel heaters are best suited to heat large open spaces with people in them. This includes things such as halls, marquees and arenas. Whilst they are more suited to commercial use, they are also ideal for industrial use as they don’t raise the relative humidity of the air. Instead, they pump large volumes of warm, clean and dry air into the environment. As they don’t increase humidity, they are also good for use in building drying during construction or after a flood.

Radiant Heaters

Radiant heaters make use of infrared heat and are mostly suited to smaller spaces however large models can heat larger spaces. They work by heating objects and people rather than the entire environment so are energy efficient.


Ventilation helps to purify the air, circulate it and control moisture in the air. Some heating systems put moisture back into the air and therefore would require adequate ventilation to be used.


Extractors work to eliminate dangerous dust and fumes in the working environment, this could be necessary on industrial sites or in warehouses. Additional ducting can be used to adjust the extractor to your specific needs. Extractors remove dust, fumes and increase air circulation in garages and workshops among other places.

Air Movers

The purpose of an air mover is to blow clean air into potentially hazardous areas. They are largely designed for use in confined spaces to make sure the air is clean and safe for workers. Alternatively, smaller air movers can be used for various drying applications in the aftermath of a flood.

Dryers and Dehumidifiers

Dryers and dehumidifiers work to remove moisture and damp from the air. They can be used in addition to direct fuel heaters which require ventilation as they add moisture, or they can also be used in the aftermath of a flood to dry out buildings. With various sizes and capacities available there are various dehumidifiers suitable for industrial purposes.

Air Conditioning

A/C Units

There are two main types of air conditioning units; exhaust tube and split type. Both work similarly, the main difference is that split type units tend to be more efficient and produce less noise. Exhaust tube systems are made up of one component whereas split type units are made of two; one of which is placed inside and the other outside. Air conditioning units tend to be a popular choice for offices, but larger systems are suitable for industrial settings.


For large scale industrial applications, chillers have a variety of uses. They can be used for large scale air conditioning as well as cooling drinking water and maintaining equipment temperature. They tend to be used a lot for the setup of temporary events and in the food and drink industry.

Evaporative Coolers

Evaporative coolers don’t require ventilation which standard A/C units do therefore they make a popular choice for buildings, factories and warehouses which don’t have open windows. Available in range of sizes to suit different applications, they work well in a number of settings.
