at a tank or furnace welded by Stocksbro, you cannot help but
admire the fine, even welding lines and connections that are always
welded at right angles. This is important when your heat,

All tanks and furnaces are covered with anti-rust protection, even
the bottom. This gives extra safety to the customer and guarantees
our products a very long life.
The thickness of the steel plating of the tanks and furnaces is
adapted to the volume and pressure they are approved for. The
thinnest steel plating is 3 mm and the largest tanks have a steel
plating of 5 mm thickness.
The Bio Sol furnace and the other insulated tanks have a special
insulation which we alone on the market supply. The insulation
consists of 90mm thick polyurethane (the best insulating material).
The foam is fire resistant (Class B2) and cast together with the
outer shell of aluminium plating. The top of the tanks and furnaces
are polyurethane foam cast with flame-proof ABS-plastic. This means
that they have excellent insulating properties as well a good fire
Thorough production for the best quality
Furnaces are manufactured according to valid EU-directives (EN
303-5) and hydrostatically tested (pressure-tested) at 4 Bar before
they leave the factory. Even the hot water and sun coils are
hydrostatically tested to check for tightness prior to delivery.
The coils are also rinsed clean to avoid impurities entering the
water system they are connected to.
The Bio-Sol furnace has been tested at TUF in Germany and is
type-approved by Swedcert.
