## Long description

The Rittal SK 3329.640 cooling unit with built-in display is an industrial enclosure air conditioner designed for climate control inside electrical cabinets and control panels. With a rated cooling capacity of up to 2550 W and operation on 400–460 V at 50/60 Hz, this grey steel‑housing unit provides stable temperature regulation for electronic components and HVAC control equipment. The integrated display allows monitoring and basic control of setpoints and status directly on the device.
Advantages
The unit delivers high cooling capacity suitable for demanding industrial environments while maintaining a compact footprint for wall or enclosure mounting. The steel housing offers mechanical robustness and corrosion resistance appropriate for typical indoor industrial sites. Built‑in display facilitates local monitoring and adjustment without additional instrumentation, and compatibility with 50/60 Hz power supplies in the 400–460 V range makes the device suitable for a wide range of installations.
Suitable for
Cooling of electrical enclosures, control cabinets and switchgear in industrial plants
Temperature control for sensitive electronic components and PLC racks
HVAC support where a compact, wall‑mounted enclosure air conditioner is required
When it may not be suitable
This cooling unit is intended for enclosure climate control and is not a room air‑conditioning system; it is not suitable for cooling large open spaces or entire rooms. Installations that require low‑noise, explosion‑proof, or specially certified equipment for hazardous locations may need a different model with specific approvals.
Key specifications
Cooling capacity: up to 2550 W
Supply voltage: 400–460 V
Frequency: 50/60 Hz
Housing material: steel
Housing colour: grey
Integrated user display for setpoint and status
Mounting: enclosure/wall mount design
How to use
Mount the cooling unit on the enclosure or wall following the manufacturer’s mechanical instructions and provide appropriate electrical connection to a 400–460 V, 50/60 Hz supply by a qualified electrician. Set the desired temperature setpoint using the built‑in display. Ensure correct air intake and exhaust paths on the enclosure, maintain recommended clearances for airflow, and fit any required filters or gaskets to preserve enclosure protection. Regularly inspect and clean condenser and evaporator surfaces and replace filters according to operating conditions to maintain rated performance.
What to consider before purchase
Verify that 400–460 V, 50/60 Hz supply is available at the installation site
Confirm the unit’s cooling capacity (2550 W) meets the enclosure heat load including installed equipment
Check enclosure dimensions and mounting space to ensure proper fit and airflow clearances
Assess ambient conditions and required enclosure protection class to ensure compatibility with the steel housing
Usage recommendations
For reliable performance, size the cooling unit to exceed the estimated enclosure heat dissipation, maintain unobstructed airflow around intake and exhaust openings, and schedule periodic maintenance—cleaning heat exchanger surfaces and replacing filters—to preserve cooling efficiency and prolong service life.
