ODT-5 met opwarmen
Indien nodig kan de ODT-5 worden uitgerust met verwarmings- en thermische isolatiesystemen. In de regel gebruiken we verwarming met een elektrische verwarmingskabel of spiraalverwarming in de tank.
Ondergrondse afwateringstank met verwarmingsspiraal:
The design provides a built-in heater in the form of a coil. Saturated water vapor, water or a 60% DEG solution can be used as a heat carrier.
The tank is additionally equipped with metal structures of a heated well.
The choice of the type of heating device is made jointly with the Customer based on the specifics of the stored product and the location of the container.
Ondergrondse afwateringstank met elektrische verwarming:
Elektrische verwarming wordt verzorgd door de zelfregelende verwarmingskabel.
Het opwarmsysteem bestaat uit:
- de verwarmingsmodule (kabel),
- de distributie- en informatiemodule,
- het besturingssysteem (schakelkast, temperatuurdetectoren en regelaars).
Warmte-isolatie:
Heat insulation of our standard underground storage tank is performed by sputtering method with rigid polyurethane foam. The sputtering is done on the outside surface of the tank. The characteristics of the heat insulation coating are determined separately for each tank depending on chemical composition and the required temperature of the stored product, climate features in the location area, etc. Overall energy loss decrease by 40 % at minimum as a result of heat insulation.
Rigid polyurethane foam coating is an effective measure, as it provides air insulation, steam insulation as well. It is highly resistant to aggressive atmosphere and shows maximum integrity with the tank surface (1.0-1.5 kg/cm²). Due to this the polyurethane foam is considered to be a perfect corrosion preventive coating.
To ensure additional toughness of the heat insulation coating it has protective seal of polyuria. The seal is also meant to increase the operating life of the coating (from 35 years) and of the tank itself as well. If the customer demands we can also provide heat insulation with the mineral wool and protective layer of galvanized steel. This type of heat insulation is considered to be more low-budget, but it has, at the same time, certain disadvantages compared to polyurethane foam coating. They are to be seen in lower rates of steam impermeability, seams on the protective layer, shorter period of operating life.
