Built-in cooling unit Rittal SK 3305510 — 1000 W input, 1730 W max cooling, 115 V, stainless steel, grey

Rittal SK 3305510 is a built-in cooling unit designed for cooling enclosures and electrical cabinets in industrial and technical environments. The unit has a 1000 W input power rating and a maximum cooling capacity of 1730 W, operates from a 115 V supply at 50/60 Hz and is finished in stainless steel with a grey coating. It is intended for continuous thermal management where stable internal temperatures are required to protect sensitive electronics and control equipment.

Advantages

The cooling unit provides a compact, integrated solution for enclosure temperature control with a high maximum cooling capacity relative to its input power. Stainless steel construction and a grey finish ensure mechanical robustness and resistance to corrosion in demanding environments. Designed for wall-mounted or built-in installation, the unit includes an electrical condensate evaporator for models at and above 1000 W, reducing the need for external drainage and simplifying installation.

Suitable for

• Cooling of electrical cabinets, control panels and small to medium-sized enclosures
• Industrial locations where continuous temperature control is required
• Applications requiring stainless steel housing for improved durability or hygiene
• Sites with 115 V power supply and 50/60 Hz mains frequency

When it may not be suitable

This unit may not be suitable for very large enclosures or rooms that require cooling capacities beyond the stated maximum of 1730 W. It is also not appropriate for installations that cannot provide a 115 V supply or where external drainage is mandatory and the evaporator cannot handle condensate loads.

Key specifications

• Input power: 1000 W
• Maximum cooling capacity: 1730 W
• Supply voltage: 115 V
• Operating frequency: 50/60 Hz
• Housing material: stainless steel
• Finish: grey
• Built-in / wall-mounted format with integrated electrical condensate evaporator (from 1000 W)

How to use

Mount the cooling unit according to the enclosure manufacturer's instructions or Rittal installation guidelines, ensuring correct orientation for wall-mounted or built-in installation. Connect the unit to a 115 V, 50/60 Hz power supply using appropriate cable and protection devices. Set desired temperature control parameters via the unit's control interface or external thermostat as specified by the manufacturer. For units with an electrical condensate evaporator, verify that the evaporator operation is enabled and that the surrounding air allows effective evaporation of condensate. Perform regular visual inspections and periodic maintenance such as cleaning of filters and checking electrical connections to ensure reliable operation.

What to consider before purchase

• Confirm enclosure size and required cooling capacity so the unit's 1730 W maximum meets thermal load demands
• Verify available mains supply is 115 V at 50/60 Hz
• Assess mounting format and clearance for built-in or wall-mounted installation
• Consider environment: stainless steel housing is suitable for corrosive or hygienic conditions

Usage recommendations

Use the unit in enclosures that match its cooling capacity and ensure routine maintenance: clean or replace filters, check condensate evaporator function, and verify secure electrical connections. Where possible, monitor internal temperature to confirm the cooling unit maintains safe operating conditions for installed components.
