Hygienic Air Handling Units for Cleanrooms: Design, Manufacturing, Components, Applications, and Price<\/p>\n
Hygienic air handling units for cleanrooms are among the most important pieces of equipment in cleanroom design and implementation. They are responsible for supplying and controlling the air required in sensitive environments. In cleanrooms, controlling airborne particles, temperature, humidity, pressure, and airflow is extremely important. Therefore, selecting a suitable air handling system has a direct impact on cleanroom performance.<\/p>\n
A hygienic air handling unit provides the required air conditions for a cleanroom through multiple filtration stages, cooling and heating systems, humidity control equipment, suitable fans, and an intelligent control system.<\/p>\n
Vira Pharmed Engineering Company, relying on engineering expertise and experience in cleanroom design and implementation, provides the capability to design and manufacture hygienic air handling units tailored to the needs of pharmaceutical, medical, food, laboratory, and other sensitive environment projects.<\/p>\n
What Is a Hygienic Air Handling Unit?<\/p>\n
To answer the question of what a hygienic air handling unit is in simple terms, it is a specialized type of air handling system designed to supply controlled air to environments with high hygiene and cleanliness requirements.<\/p>\n
In addition to supplying fresh air, this unit is responsible for filtration, temperature and humidity control, airflow regulation, and helping establish the appropriate pressure in the intended space.<\/p>\n
The difference between hygienic air handling units and conventional air handling units is not limited to the number of filters. In hygienic air handling unit design, the casing material, sealing method, cleanability, maintenance accessibility, internal design, air leakage control, and equipment selection are also of particular importance.<\/p>\n
For this reason, a hygienic air handling unit for a cleanroom must be designed and selected according to the cleanliness class, process type, space volume, and project requirements.<\/p>\n
What Are the Functions of a Cleanroom Air Handling Unit?<\/p>\n
A cleanroom air handling unit is one of the main components of the HVAC system in a cleanroom and can perform various functions, including:<\/p>\n
– Supplying fresh air
– Filtering incoming air
– Circulating air within the cleanroom
– Controlling ambient temperature
– Controlling humidity
– Regulating airflow volume
– Helping establish positive or negative pressure
– Reducing the entry of particles and contaminants
– Supplying the air required for sensitive processes
– Monitoring and controlling system performance parameters<\/p>\n
In proper cleanroom design, the air handling unit alone does not determine the cleanliness class. Instead, it must be designed as an integrated system together with ductwork, final filters, air terminals, airflow patterns, and other ventilation system components.<\/p>\n
Components of a Hygienic Air Handling Unit for Cleanrooms<\/p>\n
A hygienic air handling unit consists of various sections, each of which has a specific function in the air purification and conditioning process.<\/p>\n
1. Air Handling Unit Casing<\/p>\n
The casing of a hygienic air handling unit must be designed to minimize the risk of air leakage and contamination entering the system.<\/p>\n
In sensitive projects, the use of smooth, cleanable internal surfaces is highly important. The internal design of the unit should prevent, as far as possible, the formation of areas where dust, moisture, and contaminants can accumulate.<\/p>\n
Depending on the project specifications, corrosion-resistant and washable materials can be used for the internal sections.<\/p>\n
2. Air Handling Unit Filters<\/p>\n
The filtration system is one of the most important parts of a hygienic air handling unit for cleanrooms.<\/p>\n
Filtration is generally performed in multiple stages so that larger particles are removed first, followed by high-efficiency filters that remove smaller particles.<\/p>\n
The filters used may include:<\/p>\n
– Aluminum filters
– Primary filters
– Bag filters
– High-efficiency filters
– HEPA filters
– ULPA filters in certain specialized applications<\/p>\n
Filter selection must be based on project requirements, the cleanliness class, and the required air specifications.<\/p>\n
3. Fan and Electric Motor<\/p>\n
The fan is responsible for generating airflow and moving air through the system.<\/p>\n
Fan selection must be based on airflow rate, static pressure, filter pressure drop, ductwork, and other system components.<\/p>\n
Using a suitable fan and a speed control system can help regulate airflow more precisely and reduce energy consumption.<\/p>\n
4. Cooling and Heating Coils<\/p>\n
Cooling and heating coils are used to bring the air to the required temperature.<\/p>\n
The cooling coil can be designed to operate with chilled water or, in some projects, with a direct expansion system. Depending on project conditions, the heating system can use hot water, steam, or other equipment.<\/p>\n
The capacity of the coils must be determined based on the project’s cooling and heating load calculations.<\/p>\n
5. Humidifier and Dehumidifier<\/p>\n
In many industries, humidity control is just as important as temperature control.<\/p>\n
Excessive humidity can create favorable conditions for microbial growth, while very low humidity may cause static electricity or process-related problems.<\/p>\n
For this reason, when required by the project, the air handling unit can be equipped with a humidification or dehumidification system.<\/p>\n
6. Dampers<\/p>\n
Dampers are used to control airflow paths and flow rates.<\/p>\n
In cleanroom air handling units, precise control of fresh air, return air, and exhaust air is highly important. Dampers can regulate part of this process.<\/p>\n
7. Control and Monitoring System<\/p>\n
A modern hygienic air handling unit can be equipped with an intelligent control system.<\/p>\n
Parameters such as the following can be monitored using sensors and control equipment:<\/p>\n
– Supply and return air temperature
– Humidity
– Pressure
– Fan status
– Filter pressure drop
– Airflow rate<\/p>\n
In sensitive projects, the control system can issue the necessary alarms when parameters fall outside their<\/p>\n","protected":false},"excerpt":{"rendered":"
