Condensate Evaporator Rittal SK 3301.505 for Wall Mount, AC 115–230 V, Light Grey

The Rittal SK 3301.505 condensate evaporator for wall mount is a compact solution for removing condensate from enclosures and air-conditioning units where a drain connection is not available or practical. Designed for electrical cabinets and industrial control panels, this unit runs on AC mains with a wide input voltage range of 115–230 V and is finished in light grey to integrate discreetly with standard cabinet interiors. The device evaporates collected condensate safely, reducing the need for manual drainage and minimizing moisture-related risks inside enclosures.

Advantages

The Rittal SK 3301.505 offers reliable condensate removal without the need for floor drains or external plumbing. Its wide operating voltage range (AC 115–230 V) allows flexible connection to common power systems. The wall-mount design saves space inside cabinets and simplifies installation on enclosure walls. The light grey housing provides a neutral appearance suitable for industrial environments and electrical rooms.

Suitable for

• Electrical cabinets and switchgear where condensate forms due to temperature changes.
• Industrial control panels and automation enclosures without access to drainage lines.
• Air-conditioning units and small HVAC enclosures requiring internal condensate handling.
• Retrofit projects where adding piping to a drain is impractical or cost-prohibitive.

When it may not be suitable

This evaporator is intended for applications with moderate condensate production; it may not be suitable for sites with very high condensate volumes or continuous high humidity where a dedicated drainage system or larger industrial evaporator is required. It is not a substitute for central building drainage in installations that already have an appropriate plumbing solution.

Key specifications

• Mounting type: Wall mount for enclosure interiors.
• Power supply: AC 115–230 V input voltage range.
• Colour: Light grey housing.
• Typical application: Condensate evaporation for electrical and HVAC enclosures.

How to use

Install the Rittal SK 3301.505 on the interior wall of the enclosure at a location where condensate naturally drains toward the unit. Connect the unit to the AC mains supply within the rated 115–230 V range following local electrical regulations and safety standards. Ensure the evaporator’s outlet and heating element have adequate ventilation inside the enclosure for effective evaporation. Regularly inspect and clean the inlet area to prevent blockage and verify proper operation, especially after maintenance or environmental changes.

What to consider before purchase

• Estimate typical condensate volume to confirm the evaporator capacity is sufficient for your application.
• Check available mounting space and the enclosure’s internal layout for proper installation.
• Verify compatibility with your facility power supply (AC 115–230 V) and local electrical codes.
• Consider ambient temperature and humidity levels to determine if a passive evaporator is appropriate or if active drainage is required.

Usage recommendations

For reliable performance, mount the unit where condensate will flow to it naturally, provide proper ventilation in the enclosure, and perform periodic visual checks. If condensate production increases over time, reassess the installation and consider upgrading to a higher-capacity solution or connecting to a dedicated drain.
