ROOM FAN COIL UNITS 42N
Features and advantages
With its sleek styling the 42N encased units blend in perfectly with any room décor. The pre-painted steel panels are protected by a high-quality paint finish. The flexibility of the plastic-moulded unit drain pan allows the same unit to be installed in a vertical or horizontal position without the need for a dedicated accessory. Integrated, factory-mounted cooling and heating coil for four-pipe applications. The 42N units were designed for extremely quiet operation with sound levels that set new comfort standards for buildings. The new fan/motor assembly design ensures whisper-quiet operation (10 dB(A) less compared to the previous version). Particular attention has been given to the low fan speed, typically used at night. Motors The Idrofan is available with a multi-speed motor, extended to five fixed speeds to improve its flexibility and cover all customer applications. The Idrofan is now available with ultra-low noise levels to make it one of the quietest fan coils on the market. The Idrofan is also available with variable-speed LEC (= low energy consumption) motors, that meet the new building energy performance objectives. The LEC solution enhances unit performances offering: - Reduced energy costs - the LEC motor reduces fan coil consumption by 50 to 75%. The LEC option meets the new building energy management regulations. - Improved comfort - the LEC motor with variable fan speed reduces noise levels compared to multi-speed fans, offering ultra-quiet air ﬂow down to very low operating levels. With the NTC controller, a maximum fan speed can be set to allow better sound level management. - Maximum ﬂexibility - auto-adaptive air ﬂow rate adjust-ment from 0 to 100% ensures perfect cooling and heating conditions in the room. - Extended life time - LEC motors with brushless techno-logy use a lower fan motor temperature for extended operating life. Filters The standard filter for the Idrofan series has a pleated filtration surface, resulting in a 87% larger surface than a conventional filter, with the following additional advantages: - Lower air ﬂow per unit area, resulting in lower pressure drop and reduced noise level. - The average interval between ﬁlter cleaning is three times longer, compared to standard ﬁlters. - The ﬁlter material is polypropylene and the grade is G1. In the Idrofan series the filter is located at the bottom of the unit. Cleaning is easy: after removing a safety screw, the filter sides can be manually unclipped. The filter frame can be pulled down and the filter can then be removed easily. Re-assembly is just as easy, reversing the sequence. The filter and filter position within the unit are designed to prevent air bypass around the filter, to ensure that the air is always filtered and clean. Ease of installation The Idrofan series fan coils are extremely easy to install. For horizontal under-ceiling installations with cabinet the installer’s task is significantly simplified. Robust hooks allow easy and fast attachment of the unit. No calculations are needed to determine the correct slope for proper condensate water drainage. Even the installation of floor-mounted units is simple, the new hook dimensions and positions help fixing the units firmly against the wall. All these design aspects minimise installation time and improve the long-term reliability, avoiding small mistakes that could impair the reliability of installed units over time.
