Rittal SK 3241.700 Blue e+Cabinet Fan Filter Unit

1. Wide working temperature range

The working temperature range of SK 3241.700 is -30 ° C to+55 ° C, and the storage temperature range is -30 ° C to+70 ° C. This wide temperature range means it can adapt to various scenarios, from outdoor cabinets in cold regions to indoor distribution rooms in tropical regions. Of particular note is that its rated electrical parameters (power, current) and air flow performance data have been validated within this temperature range, ensuring reliability under extreme conditions.

2. Noise level

The noise level of this unit is 53 dB (A) (50 Hz) and 54 dB (A) (60 Hz). This noise level is equivalent to a quiet office or library environment, usually lower than the background noise in industrial sites, and does not cause additional auditory interference to operators. For special environments that are sensitive to noise, such as laboratories or medical equipment, further noise reduction can be achieved through variable frequency speed regulation or optional noise reduction accessories.

Selection and application suggestions

Scenario 1: Standard Industrial Control Cabinet

The PLC control cabinet in a certain automobile welding workshop has an internal power consumption of about 800W and is installed indoors, with an ambient temperature of up to 40 ° C. SK 3241.700 is selected as the air inlet unit and matched with the same series of air outlet filters to form convection. Based on its effective air volume of 242 m ³/h (50 Hz, equipped with air outlet filter and pleated filter), combined with the heat dissipation area of the cabinet, the temperature rise inside the cabinet can be effectively controlled within 15 ° C, ensuring that the PLC module operates at a safe temperature. The protection level of IP54 is sufficient to resist the invasion of metal dust in the workshop.

Scenario 2: Outdoor water treatment facilities

The control cabinet of a certain water plant pump station is installed in an outdoor semi enclosed pavilion, which needs to cope with rainwater and seasonal high humidity. Select SK 3241.700 and add a rain cover (rain cover accessory) to increase the protection level to IP56. At the same time, utilizing its wide temperature range of -30 ° C to+55 ° C, it ensures continuous ventilation and heat dissipation even in severe winter and summer exposure, protecting the core frequency converter from overheating and shutdown protection.

Certification and Compliance

SK 3241.700 has obtained multiple international authoritative certifications, proving its compliance in safety, electromagnetic compatibility, and environmental protection:

UL+C-UL (Recognized): Safety certification in the United States and Canada, applicable to the North American market.

CSA: Certified by the Canadian Standards Association.

KC (Korea): Korean product safety certification.

CE: Compliant with EU directives (including low voltage directive and EMC directive), accompanied by a declaration of conformity.

These certifications greatly facilitate equipment manufacturers' compliance declaration for global export of complete machines.
