Sodeca Sodeca HCH
Sodeca HCH wall-mounted axial fans, with plastic (PL) or aluminium (AL) impeller, diameters from 35 to 100 cm and airflows up to 71,850 m³/h in the datasheet table.
HCH is the Sodeca series of wall-mounted axial fans, with a sheet-steel support ring. The impeller is made of glass-fibre-reinforced polyamide 6 (PL) or cast aluminium (AL), and model 40-2T is supplied only with an AL impeller. Airflow is from the motor towards the impeller. The datasheet indicates single-phase 230 V, 50 Hz and three-phase 230/400 V, 50 Hz (up to 4 kW) or 400/690 V, 50 Hz (above 4 kW) supply, an operating temperature from -25 to +50 °C, class F motors with ball bearings, IP55 (IP54 on the single-phase models of sizes 45–56) and IE3 motors for powers of 0.75 kW or more, with the exceptions in the datasheet. On request, the following can be supplied: airflow direction from impeller to motor, reversible impeller, special windings, ATEX category 2 and vertical-shaft configuration.
The order code has the same structure as for HCT: in HCH-63-4T-1.5/PL, 63 is the impeller diameter in cm, 4 the number of poles (1,500 r/min at 50 Hz), T three-phase, 1.5 the power in HP (1.1 kW in the datasheet table), and PL the impeller material. For a quotation, please send us the complete code, the voltage and the air temperature; we check the variant in the Sodeca datasheet before sending the quotation.

Frequently asked questions
How do I read "HCH-63-4T-1.5"?
HCH is the series, 63 the impeller diameter in cm, 4 the number of poles (1,500 r/min at 50 Hz), T three-phase, 1.5 the power in HP, that is 1.1 kW in the datasheet table, with IE3 motor. After the code come PL or AL for the impeller material.
What does the suffix SEC in "HCH/SEC" mean?
The order code in the HCH datasheet has the structure HCH-diameter-poles-phase-power in HP/impeller material and does not include a SEC suffix. You can send us the complete code and the photo of the nameplate; we establish the meaning of the suffix from the Sodeca documentation for the exact code, before quoting.
What details do I send for a quotation?
The complete code or a photo of the nameplate, the voltage, the temperature of the air handled, the airflow direction and the mounting position (horizontal or vertical; HCH-100-4T-15 and -20 horizontal only).
Other Sodeca series
Curves, sound levels per frequency band, dimensions and weights are read from the datasheet for the exact code. The datasheet used is the one for 50 Hz; 60 Hz data are checked in the corresponding datasheet.
