History of fruits

Like in the good old days, Tomal had a nice orchard on the land. The first product ever invented was a fruit sprayer called Tomal Atom as there were so many trees to protect from bugs. 

Now we have plant 3 new apple trees on the ground so the historical wings are lifting again.


New assembly and packing hall

Now the insulation of the existing cold warehouse is getting close to be finalized.

Half of the hall is now insulated to get room for the sub assembly and packing of goods. As we make room in the existing production facility we will get superior use of the production floor area which at the end will give much better logistics and efficiency.


Schüttgut Dortmund 2017

Welcome to our Stand K 18-5 were Tomal show you some interesting metering equipment together with ProMinent.


Bio fuel unit for heating of Tomal.

Now we heat up Tomal with biofuel.

Our energy heating system for our production facilities has been replaced from oil to biofuel.

We feed wood pellets into our own produced Tomal silo with multiscrew feeder. The pellets is then conveyed to a pellets burner. On top of the silo we have installed solar panels and a wind mill to load the batteries in the machine room. The batteries runs the feeder motor via a 24VDC system.

At the same time we have a complete unit to show to our customers when they visit Tomal and we also use the unit for testing and development for further improvements.

30% lower consumption at Valdemarsvik WWTP

The old make-up unit became a work environment problem when polymer flooded on to the floor making it slippery.

Thanks to investing in a polymer make-up unit from Tomal, we can avoid this problem and also maintain a better

economy, according to Magnus Broström who is the technician at Valdemarsviks Wastewater Treatment Plant.



Magnus states that the consumption is lower with the new machine.

– The consumption was previously 2400 Kg polymers per year. We are down to 1700 Kg per year with Tomal’s

polymer make-up unit. That is a 30 percent saving.

Exhibition Schüttgut in Dortmund

easyFairs Schüttgut Dortmund

Welcome to easyFairs Schüttgut 2011 in Dortmund.


Large order to Poland

Delivery of a equipment for feeding powder fuel on a Polish power plant.

In successful co-operation with ProMinent in Poland, Tomal AB received, at the beginning of February, the largest order ever, worth 2,0 million EUR. A plant for feeding biofuel will be delivered to a coal-fired power plant in Krakow. One of the boilers shall be converted to burn biofuel instead of coal powder.          


Pressure from environmental organisations and the EU to reduce the burning of fossil fuels and thus reduce the addition of green house gas to the atmosphere is the background for the order.

The demand from the EU is that Poland shall replace 20% of the fossil fuels with renewable fuels by 2020 compared to the level in 1990 according to EU´s climate goal.

Scope of supply.

The delivery from Tomal consists of a storage silo with discharge and conveying system to four day silos, each with four feeders and pneumatic conveying to 16 burners. Total feeding capacity is 16 x 13m³/h which is approx. 200m³ biofuel/h or 44 tons/h. This corresponds to approx. 200MW.

Construction supervision and commissioning is included.

The plant will be delivered in stages from the beginning of April to the end of June. Construction will take place during the summer and commissioning during autumn. The plant should be ready for taking over by the end user in December 2010.

World leader concerning feeding of powder fuel.

In the beginning of the 90’s burning of renewable biomass was favoured as it was exempt from the CO2-tax. At that time Tomal AB successfully began developing feeding plants for powder fuels. Subsequently Tomal AB has extended the delivery range and is now able to deliver and take responsibility for a whole plant from pellet mills to the burners.

Tomal AB’s unique multi-screw feeders are the heart of the plant. They give an accurate and very even flow of powder fuel to the burners. This gives a stable flame from the burners. It also affords the possibility to optimise combustion and to minimise the creation of nitrogen oxide (Nox) gases which lead to acid rain and result in penalty fees.


Watec Exhibition Tel Aviv

Tomal AB will participate in the Watec Exhibition Center in Tel Aviv.
