Thermoport


For all your needs for air water & fish

The stress-free transporting of live fish requires specialist equipment. We understand the risks farmers face when moving their fish stock.


These economical and now viewed as industry standard tanks are available in four sizes: 190, 290, 600 and 800 litres. The light weight containers are produced in one piece without welds.

The new, bigger tank is made in one piece, without welds or seams. It’s made of food safe plastic (PE) which is resistant to chemicals and disinfectants, helping to maintain biosecurity between loads of fish. It is also tough, light and impact resistant.

The GRP range of LINN tanks have transported millions of tons of fish around the world. They are made completely of GRP without any wooden components, vital for bio-security.

AT LAST YOU CAN WEIGH THE FISH YOURSELF. Built to suit the full range of GRP tanks the weighing facility now offers confidence in knowing the exact weight of fish transported.

A range of sluice options is available to be factory fitted to most tank options. Whether the standard rectangular sluice opening outwards measuring 30 x 40 cm or the 200mm and 250mm internally operated ball sluices we are sure to have one to meet your needs.

Special diffuser tube, with extremely fine pores, is mounted on a robust stainless steel frame. This ensures that the oxygen is supplied as a fine, even mist across the whole tank and thus used most efficiently.

The flow meter is fitted between the pressure regulator and the oxygen diffusers. The flow meter allows oxygen to be supplied at just the right amount to every tank ensuring your fish arrive in the best conditions.

These tanks can be used for a multitude of purposes.The square tank is made of polyethylene and has integral, moulded carrying handles. Now available in 80litre round and 106litre square tank versions.

The small transport tank for live fish or crustaceans is ideally suited to fish transport on a small scale. The size of the tank is such that it can be carried even when filled with fish. Also available with its own 12 volt air support system

Air pumps are used for ventilating transport tanks, show tanks, aquariums, stock tanks or similar. The pumps have a low power consumption and run quite silently. Available in mains 230 volt and 12 volt versions for vehicular transport.








Standard outlet sluice
This ”tried-and-tested“ sluice opens outwards. It is rectangular and measures 30 x 40 cm. Before transit, the sluice plate must be fastened with the hand screw, so that the sluice is completely leak proof. The sluice plate is made from GRP. The fittings and fixings are made from stainless steel. The standard outlet sluice can be incorporated into all GRP fishtransport tanks. In order to discharge the fish an outlet slide is necessary for this type of sluice.
Outlet sluice – LINN version
The LINN sluice opens inwards and enables the tanks to be emptied easily. The sluice is opened using a handle on the upper side of the tank. The fish are released together with the water from the tank. A pipe is simply inserted into the outlet of the sluice in order to drain the fish from the tank into the pond. The sluice was constructed without edges, ruling out the risk of injury to the fish. The funnel-shaped construction enables a gentle release of the fish. The hollow sphere uses the pressure of the water to automatically and safely seal the opening during transit. No tightening or locking is necessary.

All GRP fish transport tanks are supplied with a standard lid. The purpose-built oversized lid makes it easy to transfer fish into the tank using a net. The lid is easy to open and shut. The closure mechanism is fitted inside the lid, so preventing harm to fish caused by a closure sticking out into the body of the container. The lid seal is positioned in a fold on the container and not the lid. The seal is thus protected, hardwearing and easy to replace.

0 – 5 / 0 – 8 / 0 – 15 / 0 – 25 / 0 – 35 or 0 – 50 l/min.

The round carrying tank is made of thickwalled polypropylene and has two stable handles. This container is particularly robust and durable.

The small transport tank is made from polyethylene (PE) and is therefore light, rugged and unbreakable. It is provided with two practical handles. The lid is fastened to the tank by turning (bayonet connection).
The gasket fastened around the lid opening ensures that the tank is absolutely tight and that no water can leak out. The lid has a hole though which a hose for ventilating the transport tank (air or oxygen) can be inserted. A plug for closing the opening is supplied with the tank.
