Rittal SK 3302100 TopTherm Blue e wall-mounted cooling unit, 0.31/0.33 kW cooling output at L35/L35 (50/60 Hz), 230 V. View specifications and request a quote.
Rittal SK 3302100 is a 230 V single-phase Blue e TopTherm wall-mounted cooling unit for electrical enclosures. It removes heat from control equipment when ventilation alone cannot maintain the required cabinet temperature. The unit has a basic temperature controller and a compact steel housing for installations with limited mounting space.

At 50 Hz, SK 3302100 provides 310 W at L35/L35 but only 150 W at L35/L50. L35/L35 refers to an enclosure internal temperature of 35 °C and an ambient temperature of 35 °C; L35/L50 uses the same internal temperature with a 50 °C ambient temperature. Use the rating that matches the installation conditions rather than selecting from the 310 W value alone.
Calculate the required cooling duty from component heat losses and heat transfer through the enclosure. If that duty exceeds the available output at the design temperatures, choose a higher-capacity model. Check the mounting cut-out, cabinet strength and clear airflow paths before ordering; the overall dimensions are not the cut-out dimensions.
The unit is supplied wired for connection, with its RiNano-coated condenser, drilling template and assembly parts. Site installation still requires the cabinet cut-out, electrical connection and a suitable condensate discharge route.
Plan condensate drainage. The 3302.xxx units discharge condensate through a drain connection and require a hose arrangement following the installation manual. An external condensate evaporator is an optional accessory; it is not an integral feature of this model.
The specification table follows Rittal’s current R-513A product listing. For a replacement unit, check the existing nameplate and use the instructions matching its refrigerant version. Read the model-specific certificate scope when an approval is required by the project.
Select accessories according to condensate handling and the surrounding air. Confirm the accessory article number and compatibility with SK 3302100 before adding it to the order.
