Two companies have worked together to achieve a great successful case related to energy saving.

Ardal S.A., the principal producer of autoclaved aerated concrete bricks (AAC), based in Victoria, Entre Ríos, Argentina, presented the need to have a solution for energy saving. Flowproen, a company specialized in providing industrial equipment which aims at reducing costs and optimizing those processes, analyzed the situation with the customer to understand the needs and presented the heat recovery Skid FLOW 250/ST CW Automatic, which offered Ardal great benefits.

Why did Ardal contact Flowproen?

Ardal had identified an important energy saving point but there were technical issues to solve and that is why they decided to contact Flowproen.

The customer told us that they had never had any energy saving equipment and that some years ago, they tried to make use of the exhausted steam energy by using a coil designed and made in their own workshop, which only worked for six months and was removed from the process because the erosion ended up destroying the equipment.

Distinguishing characteristics of the heat recovery Skid

The customer was amazed at the heat recovery Skid (FLOW 250/ST CW Automatic) characteristics and benefits, and told us the three most important items for them:

‘They highlighted the quality of control elements used, valves, sensors, motor, etc. They told us the PLC works at any parameter correcting fast. They highlighted the Skid has become a very important piece of the system because it doesn’t produce any mistakes and it is very precise. Finally, they remarked on the compact size of the Skid and its high transfer capacity. It’s a small equipment which adapts easily due to the fact that it is placed in a Skid.”

Benefits obtained by the customer after implementing the heat recovery Skid

The customer highlighted the reduction of a 9.7% in gas consumption, according to his records, from the beginning of the setup and during the following months.  This reduction represents a considerable cost and helps to payback the equipment.

They told us that the increase in the temperature of the feedwater to boiler not only advantage the evaporation rate, helping recovery during moments of high steam consumption, but also reduce boiler vibrations. The feedwater enters the boiler with a smaller percentage of dissolved oxygen and consequently there is a reduction of chemicals in the treatment of the feedwater.


Final results

  • 9.7% Energy Saving
  • 301,6 Tn/Year reduction of CO2 emission
  • Investment payback in less than a 20-year-period
