Fin Tube----Finned tube coils with shell
By the use of High Performance Finned Tubes, LOK Tube Coil Heat Exchangers are particularly compact and efficient. As large heat exchange surface areas can be installed in a small space LOK Tube Coil Heat Exchangers have a particularly favourable price-performance ratio.Due to the unscrewable cover flange, the heat exchanger can be removed for cleaning purposes.LOK Tube Coil Heat Exchangers are available as external heat exchangers (design types S and M) and as coolers for mounting in tanks (design type T).
LRK Tube Coil Condensers consist of a cylindrical steel shell containing the finned tube coil of copper. The shell is of welded construction and equipped with fixing brackets.The refrigerant vapour enters the vertical shell and condenses on the finned tube spirals. The falling condensate is collected in the lower part of the shell. In one design type the condensate is even subcooled by another finned tube spiral.The cooling medium, usually domestic or heating water, flows in the opposite direction on the inside of the finned tube spirals.
LRV Tube Coil Evaporators consist of a cylindrical steel shell containing the finned tube coil of copper. The shell is of welded construction and equipped with fixing brackets. The total shell surface is protected outside and inside with a plastic coating against corrosion.Due to the unscrewable cover flange, the heat exchanger can be removed for cleaning purposes.
The refrigerant is uniformly injected into the individual finned tubes by means of a manifold unit. The heating medium is circulating in cross-counter current on the shell side around the tube coil heat exchanger.
The HGW Tube Coil Heat Exchangers consist of one or two tube coils from copper, which are brazed into a cylindrical cupro-nickel shell. The ends of the tube coils can be connected directly with the tubing outside the shell. By this design a brazing seam between tube and shell side - e. g. refrigerant/oil mixture and domestic water - is avoided.
The hot gas flows on the shell side of the HGW Tube Coil Heat Exchanger. This hot gas, dependent on intended application, cools down or condenses on the extended outer surface of the fin tube coils. The cooling medium to be heated flows in the tube coil according to the counter flow principle, thus heating to above the condensing temperature of the refrigerant.
