Decometa : Finned Tubes

<body> <b><font size="3">Aircoolers - Aircondensors - Gascoolers - Preheaters - Heat Recovery</font></b> <p>All these units will be equipped with their most applicable type of finned tube (high fin or low fin).</p> <p>The most frequently used types of <b>finned tubes</b> are :</p> <ul> <li> <u>L-fin helical</u><br> material tube : carbon steel, stainless steel<br> material fin : ALU<br> The alu Fin has a base of the L shape, and is in contact with the carbon steel tube itself.<br> working temperature : up to 150°C<br>  </li> <li><u>Knurled "L" wrap on finned tubes - helical<br> </u>material tube : carbon steel, stainless steel<br> material fin : ALU<br> working temperature : up to 250°C<br>  </li> <li><u>G-fin - helical</u><br> material tube : carbon steel, stainless steel<br> material fin : ALU<br> The alu fin is crimped into a groove in the basic tube.<br> Used up to 400°C.<br>  </li> <li><u>Extruded - Bimetalic - helical</u><br> material tube : carbon steel<br> material fin : ALU<br> The fins are extruded from a basic Alu tube which formed the previously encasement of the carbon steel inner tube.<br> Used up to 250°C.<br>  </li> <li><u>TIG welded with finned tubes</u><br> material tube : carbon steel, stainless steel<br> material fin : ALU, carbon steel, stainless steel<br> High frequence welded tubes for high temperature conditions. <br>  </li> <li><u>I-fin - helical hot dip galvanised</u>  (used up to 350°C) (*)<br> material tube : carbon steel<br> material fin : ALU<br> These tubes are common used for central heating of buildings, greenhouses and rooms.<br>  </li> <li><u>I-fin - helical Stainless steel</u>  (used up to 150°C) (*)<br> material tube : stainless steel<br> material fin : stainless steel<br> This type is used up to 200°C.<br>  <br> (*) for more information, see our <a href="fin.htm">finned tubes</a> production programme</li> </ul> Decometa is focused on serving <u>clients in the following industries</u> : <ul> <li>oil and gas installation</li> <li>food industry, sugar mills</li> <li>rendering industry</li> <li>incineration</li> <li>electric furnace cooling</li> </ul> <p>We select the <u>most economical, ecological and low maintenance solution</u> for your <b>dry cooling</b> or <b>heat recovery installation</b>.</p> <ul> <li>Type : forced -, induced - or natural draught</li> <li>maximum heat transfer efficiency</li> <li>No air blanketing in condensors</li> <li>low fan power</li> <li>low maintenance cost and safe construction</li> <li>low noise</li> <li>eventually air recirculation</li> <li>freezing protection</li> <li>corrosion resistance : due to selection of materials, corrosion allowances and avoiding the existence of air pockets</li> <li>modular cells</li> <li>mechanical and thermal integrity</li> </ul> </body>
