Ekoflow heat exchanger

Ekoflow utilises the heat energy in wastewater to provide effective energy recovery, achieving efficiencies of up to 85 %. The return of investment is just a few years. For best preformance, plan for the heat exchanger in the earliest project stage possible. Optimizing the dimensions is the key for maximum energy recovery.

 

Facts in brief

  • Ekoflow is suitable for recovery of heat from wastewater
  • Efficiencies of up to 85 %
  • Ideally suited to many uses, including industrial, residential, hotels, swimming pools, sports complexes, hospitals, laundrettes, etc.
  • ROI is approximately 3 years

 

Dimensioning and subsequent monitoring

Isakssons provides a calculation program for maximum optimization and dimensioning, plus measuring equipment for subsequent monitoring of  efficiency and energy savings. The measuring equipment is connected to the heat exchanger and provides ongoing information on efficiency levels and energy savings.

 

Maintenance

Ekoflow has a reliable and simple system solution that is easy for the customer to maintain. All models have a hatch providing good access for cleaning. The cleaning process takes around 10 minutes and should be carried out at least once a month.

 

Design

  • Twin-tube counterflow heat exchanger
  • Compact design
  • Acid-resistant stainless steel tubes
  • Capacity under own pressure (no pump): approx. 4 litres/sec
  • Blackwater/greywater separation leads to more effective energy recovery
  • Cleaning hatch helps ensure ease of maintenance
  • Available in a variety of sizes and can be specially tailored to requirements. Ekoflow can be dimensioned for other flow ranges and adapted for pump operation, intermediate circuit and/or heat pump

 

For a facility with 40 showers, Ekoflow 15:6 delivers annual savings of 560,000 kWh, i.e. approx € 28 000.
