£271.23
The Rittal SK 3201.990 is a purpose-designed connection set for Rittal air/water heat exchangers, providing the hoses and fittings required for professional water connection and controlled coolant flow. It is compatible with selected Rittal SK air/water heat exchangers in the 3209 to 3375.XX0 range.
The set is designed to simplify the installation of water supply and return lines between a compatible heat exchanger and the cooling-water circuit. Its pressure hoses can be shortened individually to suit the installation, with a maximum supplied length of 3600 mm, helping installers route connections cleanly inside machinery and enclosure systems.
Water-carrying components are manufactured from EPDM and brass, while the supply hose incorporates a balancing valve for volume-flow regulation. The valve provides an adjustment range of 3–12 l/min, helping match coolant flow to the requirements of the connected air/water heat exchanger.
Air/water heat exchangers rely on a controlled flow of cooling water to remove heat from electrical enclosures. The Rittal SK 3201.990 provides a coordinated supply and return connection arrangement, helping installers route the cooling circuit correctly while maintaining a suitable coolant volume flow.
The integrated balancing valve allows the water flow to be adjusted between 3 and 12 l/min, helping prevent unnecessarily high flow rates while matching the requirements of the connected heat exchanger. The flexible pressure hoses can also be shortened individually, making the set suitable for a wide variety of enclosure and machine layouts.
