## Summary description

Rittal SK 3209500 is an air-to-water heat exchanger for enclosure climate control. It provides up to 2500 W cooling capacity with an airflow of 0.1111111111 l/s, powered by 110 W at 230 V and 50/60 Hz. Constructed from stainless steel with a built-in display, it is suited for cooling electrical cabinets and industrial housings where reliable temperature control is required.

## Long description

The Rittal SK 3209500 air-to-water heat exchanger is designed to manage enclosure climate by transferring heat from inside electrical cabinets to a water circuit. With a nominal cooling capacity of 2500 W and a stainless-steel housing, this roof-mounted unit is intended for industrial environments where robust temperature control and corrosion resistance are required. The unit operates from a 230 V supply at 50/60 Hz and consumes 110 W during operation. A built-in display allows local monitoring and basic status indication.
Advantages
This heat exchanger delivers a compact, roof-mounted solution that removes heat without introducing external air into the enclosure, reducing contamination risk. The stainless-steel construction provides enhanced durability and corrosion resistance for harsher ambient conditions. The built-in display enables quick visual checks of operating status, while the modest power consumption helps to minimise auxiliary energy use. Designed for easy integration with a water cooling circuit, it offers flexible connection options for many industrial setups.
Suitable for
Cooling electrical control cabinets and switchgear in industrial facilities
Applications requiring closed-loop cooling to prevent ingress of dust or moisture
Enclosures exposed to corrosive or humid environments where stainless-steel construction is beneficial
Systems where a roof-mounted installation is preferred to save internal space
When it may not be suitable
It may not be appropriate for installations that require active heating or very precise temperature control beyond basic cooling capacity. Systems without access to a compatible water circuit for heat rejection cannot use this air-to-water exchanger as intended. Very small enclosures where a lower-capacity or air-only cooling solution is sufficient may find this unit oversized.
Key specifications
Cooling capacity: 2500 W
Airflow (nominal): 0.1111111111 l/s
Power consumption: 110 W
Supply voltage and frequency: 230 V, 50/60 Hz
Housing material: stainless steel
Mounting type: roof-mounted
Integrated display for local status indication
How to use
Mount the unit on the roof surface of the enclosure following manufacturer mounting points and sealing requirements to maintain enclosure protection. Connect the heat exchanger to the facility water circuit using suitable hoses and fittings, observing recommended flow rates and water quality to avoid corrosion or fouling. Provide the 230 V supply and verify correct electrical connections. Use the built-in display to check operational status and basic parameters. Regularly inspect the external housing, water connections and internal heat exchange surfaces for leaks, scaling or blockage and perform scheduled maintenance according to operating hours and water conditions.
What to consider before purchase
Availability of a compatible water cooling circuit and required flow/return connections
Enclosure dimensions and roof mounting space to ensure correct fit and clearances
Required cooling capacity for the installed components to confirm 2500 W is adequate
Water quality and filtration needs to prevent scaling and maintain heat transfer efficiency
Usage recommendations
For reliable, long-term performance, install appropriate water treatment and filtration, verify mounting seals to preserve enclosure protection, and schedule periodic inspections of heat exchange surfaces. Use the built-in display for routine checks and integrate monitoring into facility controls if required for continuous supervision.
