Air conditioner indoor unit Rittal SK 3185.830, column type, 620 W cooling, 700 m³/h airflow, 110–240 V

The Rittal SK 3185.830 is a wall-mounted indoor cooling unit from the Blue e+ series designed for industrial enclosures and control cabinets. It provides nominal cooling capacity of 620 W and a cooling airflow of 700 m³/h in a compact column-style indoor unit finished in grey. The unit accepts 110–240 V AC at 50–60 Hz and is factory-set to switch at 35 °C.

Advantages

Blue e+ technology combines speed-regulated components and heat-pipe heat recovery to reduce energy consumption substantially; average energy savings of up to 75% are possible compared with conventional units. The SK 3185.830 is available in sheet steel or stainless steel versions and offers a compact, wall-mounted design that fits into industrial environments and control-room interiors where space is limited.

Suitable for

• Cooling small to medium electrical enclosures and control cabinets
• Industrial cabinets in production and automation environments
• Applications requiring wall-mounted, space-saving indoor cooling

When it may not be suitable

This unit has a nominal cooling capacity of 620 W, so it may not be sufficient for large enclosures with high heat loads or systems that require precise temperature control below factory thermostat settings. For outdoor installations or applications exposed to weather you should select a purpose-built outdoor or higher-capacity cooling solution.

Key specifications

• Cooling capacity (nominal): 620 W
• Cooling airflow (indoor unit): 700 m³/h
• Indoor unit type: Column (wall-mounted)
• Factory thermostat setting: 35 °C
• AC input voltage: 110–240 V
• AC input frequency: 50–60 Hz
• Color/finish: Grey; available in sheet steel or stainless steel

How to use

Mount the SK 3185.830 on a suitable interior wall of the equipment room or directly on the enclosure according to Rittal installation instructions, ensuring adequate airflow around the unit. Connect to an AC supply within the rated 110–240 V and 50–60 Hz range. Set the thermostat as required (factory set to 35 °C) and verify cooling performance under typical load conditions. Perform regular filter and heat-exchanger maintenance to preserve efficiency.

What to consider before purchase

• Required cooling capacity compared with the nominal 620 W output
• Available mounting space and suitability of a wall-mounted column unit
• Indoor vs. outdoor installation requirements (unit is an indoor wall-mounted model)
• Material preference: sheet steel or stainless steel version availability

Usage recommendations

For energy-efficient operation, allow proper ventilation around the unit, keep filters clean, and verify that internal cabinet heat loads do not exceed the nominal 620 W. If higher cooling capacity or outdoor mounting is needed, choose an appropriate Rittal model with greater output or outdoor rating.
