The Carrier Idrofan 42WM is a high-performance hydronic high-wall fan coil unit engineered for versatile climate control in commercial environments. Available in two models and four sizes, this unit delivers cooling capacities ranging from 1.2 kW to 3.8 kW and heating capacities between 1.3 kW and 4.3 kW. Its sleek RAL 9003 finish ensures it integrates seamlessly into professional spaces, while its design emphasizes low energy consumption and quiet operation. The casing is constructed from high-specification, self-extinguishing ABS plastic that resists aging, protecting the internal components effectively. Technical flexibility is a hallmark of the 42WM series, which supports both AC and EC motor options to suit different efficiency requirements. The AC motor features six fan speeds and internal thermal protection, whereas the EC version utilizes a high-efficiency permanent magnet brushless motor. Maintenance is simplified through the use of an easily accessible, washable, and regenerable synthetic air filter. The heat exchange coil, crafted from drawn copper tubes with mechanically bonded aluminum fins, ensures optimal thermal transfer, making this an ideal solution for modern hydronic installations requiring reliable performance and aesthetic appeal.
