Tanks with insulation
All tanks from CGH can be supplied with heating and insulation.
This applies to aboveground tanks according to EN12285-2, underground tanks according to EN12285-1 and vertical tanks. The tanks can all be designed as single-skinned or double-skinned tanks. It is primarily the medium in the tank and the conditions at the installation site that determine the need for heating and insulation of tanks. Many fluid such as biodiesel and heavy fuel (HFO) must be kept at a certain temperature in order to be usable/pumpable, while other liquids simply need to be kept frost-free. Regardless of the need, CGH has a solution for the current task.
There are different ways in which the contents of the tank can be heated, and the solution is always adapted to the current project
- Heating coil installed in the manholes of the tank. For hot water or steam.
- Heating pipe installedat the bottom of the tank. For hot water or steam.
- Electrical tracing / heating cables around the outside of the tank, in whole or in part.
- Heating cartridges mounted in sleeves/flanges.
How much heating that must be supplied to the tank depends, among other things, on requirements for the medium's operating temperature, ambient temperature, insulation thickness, the temperature of the medium in the heating coil/heating pipe or the effect on the heating cable/heating cartridge.
Aboveground tanks are typically insulated with 100 to 300 mm tank insulation, which is covered with a cover plate. The cover plate can be made in many different materials according to customer requirements . The standard cover plate is 0.7 mm aluzinc, but aluminum, seawater resistant aluminum, and stainless steel plate are also among the options.
Insulation of underground tanks is typically carried out with approx. 100 mm waterproof PU foam.
