Introduction to industrial ventilation problems and their causes

Without doubt efficient air circulation is important in all kinds of industrial facilities. Properly designed and well maintained system provides fresh air and removes all the pollutants. Incorrect installation of the unit or failure to follow all manufacturer's guidelines can lead to problems that affect the performance and life of the air handling unit, or even can damage it. If you want to be sure that everything will be suitable for your business, you have to take all factors under consideration. First of all, it is all about good project and perfect workmanship. Engineers always take care about efficiency and overall costs of ventilation system. But sometimes not everything is predictable and few mistakes in maintenance of the system can cause serious issues. Let’s take a closer look to the most common industrial ventilation problems and ways to solve them.

The most common industrial ventilation problems and their causes

It is important to find the problem before general malfunction – inadequate air flow, problems with filtration systems, insufficient air circulation or equipment failure? If you pinpoint the exact issue, you can find the cause of it. Lack of proper maintenance of the industrial ventilation results in poor performance – only systematic monitoring prevents unexpected failures throughout the life of the system. Worn parts are one of the most common causes, due to their constant use. It is substantial to check everything regularly, especially when some strange noises appear. Parts such as compressors, fans and thermostats are highly susceptible to wear and defect due to continuous usage. Another important issue is the inspection of air-purifying filters. Clogged and worn filters cause a drop in overall performance. Such filters can also cause the air purification system to work poorly and reduce air quality. Of course, it is not worth using cheap substitutes – only original and matching filters will ensure good operation of the ventilation system and reliability. As you can see, the most common industrial ventilation problems and their causes is a very complex matter and you better trust the professionals – they will find and remove them successfully.

Effective solutions for industrial ventilation problems

Choosing the right type of ventilation depends on the size and layout of the facility, but also  on the types of pollutants. Even if you are aware of the importance of air quality and cleanliness, it is worth leaving the choice of the most effective and inexpensive pollutant removal solution to the professionals. Industrial ventilation systems works on two basic mechanisms: one to remove contaminants from the workplace, the other to circulate fresh air back into the facility. First and foremost, you should choose units from reliable suppliers that have trained technical and service personnel and use good quality components. Proper selection and design of the air handling unit is the basis for it to function and perform its task correctly. Regular maintenance of the ventilation system and inspections, removal of contaminants, mechanical maintenance of air exchange system components, checking for leaks and correct airflows all contribute to its optimal functioning. Monitoring and automation of the air purification system will also help to keep everything in perfect condition. More and more effective solutions for industrial ventilation problems are constantly developing – let’s check out the latest ideas.

Practical tips for improving ventilation in industry

Upgrading industrial ventilation improves performance, energy efficiency and results in optimal system operation. You may want to consider using modern filtration systems, more efficient fans and sensors to monitor air quality. Heat recovery systems will significantly reduce the energy consumption and give quite large savings. In a typical industrial installation, there are many vibrations and oscillations generated by the ventilation equipment - operating fans, air handling units or chillers. A well-installed duct network should have built-in components to counteract or significantly reduce the transmission of these vibrations. Also, it is worth to get knowledge about some air flow control systems. Supplying fresh air and removing the same amount of contaminated air is the main task of a ventilation system. To achieve this, control dampers or volume flow controllers are used. The role of airflow regulators is to maintain desired airflow rate in particular branches of ducting system regardless pressure variation inside the ducts. These modern air volume control systems: VAV (Variable Air Volume) or CAV (Constant Air Volume) can be used, depending on the type of ventilation system. What’s more? Insulation is used to protect the ventilation system from condensation, against fire and to reduce the noise of the air flow. The right choice of insulation will minimize heat loss in the ventilation system and, in the event of fire, will not be the cause of fire spreading. Factors affecting the correct airflow like incorrect air duct layout, ducts that are too small or too large, incorrectly adjusted valves and fans can be also optimized. You may also consider to install duct silencers, used  to attenuate noises in ventilation ducting. In most cases, they are mounted between the fan and the diffusing or exhaust fan and before the air diffusers. Implementing a strict maintenance schedule for cleaning and replacing filters ducts and fans will keep the whole system in best condition. As you can see the list of tips for improving ventilation in industry is really long.

To sum it all up – improving your ventilation system means that everything will be compliant with legal requirements and standards. It is very important to consult everything with HVAC – Heating, Ventilation and Air Conditioning experts before any upgrades. Remember, everything must be calculated and chosen to meet your expectations.
