Description
Unlike the HTMF and THT/ROOF series, these fans are not certified for smoke extraction and work as general extraction. HTMV has a galvanized steel base with anti-corrosion treatment, an adjustable cast aluminum impeller, a protective guard to UNE-EN ISO 12499 and a non-return damper made of aluminum sheet that keeps water out when the fan is stopped. Sizes are 56–125, with 4-pole and 6-pole versions and a power of 0.55–37 kW. HTMH has a painted galvanized steel base, a pivoting cast aluminum impeller, a guard and a cowl with a natural air outlet, and a surface of class C4H, or C5M on request. Sizes are 56–125, 0.55–15 kW, with 4-pole, 6-pole and 8-pole versions. According to the datasheets the air temperature is −20…+40 °C for HTMV and −25…+50 °C for HTMH. The class F motors are IP55, with a supply of 230/400 V 50 Hz up to 4 kW and 400/690 V 50 Hz above 4 kW.
How to choose
For explosive atmospheres there are HTMV/ATEX and HTMH/ATEX with 2G/2D certification. On request, two-speed motors, 2-pole and 8-pole versions depending on the diameter, fully stainless or hot-dip galvanized versions, and motors to CE, NEMA, UL and CSA standards are available. For HTMH there are marine motors certified by the classification societies BV, DNV and LR. Between the series the choice is made by airflow, since HTMV goes up to 37 kW and HTMH up to 15 kW. They are installed in metallurgical and foundry areas, hangars, cold stores and on ships.
