ISO classes for Cleanrooms

Cleanrooms and related controlled environments are designed to manage airborne contamination to levels suitable for activities sensitive to such contamination. Industries that benefit from this level of control include aerospace, microelectronics, pharmaceuticals, medical devices, healthcare, and food production.

This section of ISO 14644 outlines the testing methods that can be employed to characterize a cleanroom, as detailed in other sections of ISO 14644.

NOTE: Not all testing procedures for cleanroom parameters are included in this section of ISO 14644. Additional procedures and equipment for characterizing other relevant parameters in cleanrooms and clean zones tailored for specific products or processes are addressed in other documents produced by ISO/TC 209. Examples include procedures for controlling and measuring viable materials (ISO 14698), assessing cleanroom functionality (ISO 14644-4), and testing separations.

How to control Temperature and Humidity in Air Handling Unit

How to control Temperature and Humidity in Air Handling Unit Overview Air Handling unit is a system used to supply temperature and Humidity controlled filtered air to the cleanroom. For air filtration various types of filters are used in AHU. And for temperature and Humidity controlling cooling and heating coils are provided in AHU. Goals Control the temperature of air used in the cleanroom Control the humidity of air used in cleanroom Air filters Specifications The air Handling unit consists of Air filter Cooling coil Heating coil Air blower HEPA Filter Controlling of Temperature and Humidity By Cooling Method The cooling coil recirculates the chilled water having temperatures between 4°C to 6°C. This chilled water comes from the Chiller through centrifugal pumps. When we start the Air Handling unit blowers sucks the air through the pre filters of the air Handling unit. When blowers sucks air, it passes through the cooling co...

Why ice forms at cooling coil and Suction line in Refrigeration system

Why ice forms at cooling coil and Suction line in Refrigeration system it's all about the relationship between a temperature and pressure and how the pressure affect the boiling point of the refrigerant. As the pressure of refrigerant increases then the temperature and boiling point also increases, when pressure decreased temperature and boiling point also decreases. Refrigeration and air conditioning systems take use of it to cool the air or liquid. Normal Refrigeration System In normal refrigeration system compressor compresses the refrigerant which causes the increase in pressure and temperature of refrigerant. The hot vapour refrigerant pass through the condenser in condenser heat exchange happens and refrigerant condensate into liquid forms.Before entering in the evaporator high pressure liquid refrigerant pass through the expansion of valve. The actual device used depends on the Refrigeration system but capillary t...

HVAC Validation In pharma Industries

HVAC VALIDATION As per ISO guidelines for HVAC validation. In HVAC Validation below points are determined and validated that they are in within range as per designed which will pass the respective ISO standard class acceptance criteria. 1)Air velocity and CFM calculation 2)Air changes per hour 3) Installed filter leakage test 4) HEPA filter integrity test 5)Air flow pattern test or smoke test 6)Partical count test 7)Total variable count 8) Temperatur and pressure monitoring 9) Temperature and Humidity recovery test 10) Fresh air calculation All this points are determined recorded in documents.All this validation process done by validation contractors under observation of respective company Engineer. 1) Air velocity and CFM calculation :- - Scan the area of the HEPA filter with probe of anemometer 6 inches from the filter face. - For accurate velocity take the velocity of air at five place of filters ( Four corners and centre of filter) - Record the air velocity i...
