Cleanliness and hygiene are the be-all and end-all – whether in the food, semiconductor, pharmaceutical or aerospace industry. Especially in clean and ultra-clean rooms, each microscopic particle of dirt is measured. Different regulations set limits for maximum particle pollution of the volume. ALTMANN clean room cranes meet all the requirements.
Maximum allowable concentration of particles per m³ for the clean room classes according to ISO 14644-1
Clean room class ISO 6 (ISO 146441)
* Clean room classes and particle concentrations per ft3 according to US Federal Standard 209D (for comparison)
** Reference particle size for definition of class (no measured quantity!)
*** This class has been introduced particularly with respect to the assessment of clean rooms being installed.
We plan and manufacture reliable clean room cranes up to clean room class ISO 6 (ISO 146441), 4 (VDI 2083) respectively 1000 (US FED STD 209E). Each clean room crane (suspension crane, trolley, etc.) is individually tuned to the customer’s application to achieve maximum lifting height particularly in low rooms, which is generally the case.
The choice of the right component surfaces, lubricants, avoidance of abrasion and evaporations are only some of the aspects we take into consideration in order to develop and install an adequate crane system (clean room crane, suspension crane, trolley etc.) which is exactly tailored to your application.
