Heating Coil Module

Depending on the capacity and operational conditions, heating coils are placed in this module. The coils which used with steam or hot water are made of copper tubes with aluminum fins. Steel tube/steel fin, stainless steel or galvanized steel finless tubes or electrical resistance heaters can be utilized optionally. The heat exchanger is designed to achieve the optimum pressure drop on both air and water sides. Usually heating coils' headers are equipped with carbon steel pipes whereas steam coils' headers are copper. Water inlet sides for heating coils are from lower part of it whereas steam inlet is upper part of the steam coil. Supply air faces with exiting water/steam in order to gain energy for higher efficiency from heat transfer process. Air velocity on coil can exceed 3 m/s if there is no cooling coil after it. All coils are selected with certified softwares and suitable to work under gauge pressure of 13 bar. Test pressure is 20 bar.

Cooling Coil Module

As air move through a cooling coil, heat transfer process begins. Air loses its heat while going through the surface area of the coil. The amount of heat loss depends on the length of the coil. The coils are made of copper tubes with aluminum fins. The headers of cold water coils are usually made of carbon steel and copper for hygiene coils. Proper maintenance of cooling coils should be made periodically. Frost protection thermostat should be equipped with the cooling coil where winter conditions are below 5°C. A separator is used when the face velocity of the cooling exceeds 2 m/s. Separators are designed and produced to catch the maximum amount of water. Separators are made of mechanically and thermally high-strength ABS material. Supports for the separator and the condense tray are made from stainless steel. All the coils are selected with certified software and suitable to work under gauge pressure of 13 bar. Test pressure is 20 bar.

ACCESSORY EQUIPMENTS for COIL MODULE:

  • Ball Drainage Siphon: U trap for drainage, working with water gauge pressure principle avoiding the drainage water to go one-way only
  • Anti Frost Thermostat: Thermostat which avoids any possible occasions by freezin
