Sodeca Sodeca HCT
Sodeca HCT tubular axial fans, with plastic (PL) or aluminium (AL) impeller, diameters from 25 to 100 cm and airflows up to 71,850 m³/h.
HCT is the Sodeca series of wall-mounted tubular axial fans, with a tubular sheet-steel casing and external terminal box. The impeller is made of glass-fibre-reinforced polyamide 6 (PL) or cast aluminium (AL), and models 40-2T and 45-2T are 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, for powers of 0.75 kW or more, IE3 motors, except the single-phase, two-speed and 8-pole ones.
The order code is read as follows: in HCT-40-2T-1.5/PL, 40 is the impeller diameter in cm, 2 the number of poles (2 = 3,000 r/min at 50 Hz, 4 = 1,500, 6 = 1,000), T three-phase (M single-phase), 1.5 the power in HP, and PL or AL 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
What does "HCT-45-2T-2/AL" mean?
HCT is the series, 45 the impeller diameter in cm, 2 the number of poles (3,000 r/min at 50 Hz), T three-phase, 2 the power in HP (1.5 kW in the datasheet table), AL aluminium impeller. Models 40-2T and 45-2T are supplied only with an AL impeller.
What is the difference between HCT and HCH?
The Sodeca datasheets describe HCT as a tubular axial fan, and HCH as a wall-mounted axial fan with a sheet-steel support ring; the motors, impellers and power supply are described similarly, and the order code has the same structure.
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 desired airflow direction and, where applicable, the ATEX requirement.
