The DHTECO device was installed in the cooling circuit, which is used to cool an ammonia circuit. The cooling water circulates continuously in the system. The water addition varies over time and depends on evaporation.
ROI 12 – 15 months
Savings (energy, service, spare parts):
In the 1st year: 20% energy saving corresponds to approximately 5,200 euros
In 5 years: Total energy savings of approximately 26,000 euros, which corresponds to a saving of 400% to 450%
Conclusion:
Before installing the DHTECO device, the customer had to constantly maintain, clean, repair and replace the components of the cooling system annually, which resulted in high annual costs. The clean cooling surfaces enable a shorter cooling time, resulting in significant energy and cost savings.

With DHTECO
Test period:
1. September 2022 – 7. December 2022
Parameters:
Water hardness 16 – 18 dH,
Flow rate 33.6 m3/h
Functional description:
The DHTECO device was installed in the cooling system tank on a pumping station, where the cooling water continuously circulates in the cooling system. The system size is 600 m3, the volume flow is 300 m3/h. The water addition varies over time and depends on evaporation.
ROI was 6 – 8 months
Savings (energy, service, spare parts):
In the 1st year 33% to 50%
In 5 years 400% to 450%
Conclusion:
Before installing the DHTECO device in the area under study, the customer had to constantly maintain, clean, repair and annually replace the components of the cooling system. Therefore, the annual costs were high. After the positive test results, the decision was made to purchase and install the DHTECO device to ensure maximum efficiency of the cooling system and reduce overall costs.

Water heating
Test period:
18. November 2022 – 25 November 2022
Parameters:
Water hardness 16-18 dH,
Flow rate 0.55 m3/h
Functional description:
The DHTECO device was installed on an industrial washing machine. The washing machine tested was a brand new 50 kg machine with a water volume of 180 l.
The power of the installed heaters is 5 kW per heater and a contact temperature of 270°C. There are 9 heating elements installed in the machine, which reach a power of 45 kW.
Savings (energy, service, spare parts):
20% in the 1st year
300% to 500% in 5 years
Conclusion:
For every ton of laundry washed, up to 50 minutes of heating time and up to 34 kWh of energy are saved.

Air cooling
Test period:
10. May 2023 – 28. May 2023
Parameters:
Water hardness 17 dH,
Flow rate 3.6 m3/h
Functional description:
The DHTECO device was installed in an air cooling system in a larger building.
ROI was 6 – 7 months
Savings (energy, service, spare parts):
In the 1st year 40% to 50%
In 5 years 400% to 450%
Conclusion:
Before installing the DHTECO device in the tested area, there were constant costs for maintenance, cleaning and repair of the components of the air cooling system, as well as for their frequent replacement.
After the positive test results, the decision was made to purchase and install the DHTECO device to ensure the maximum efficiency of the cooling system and reduce overall costs.

Water supply
Test period:
28. November 2022 – 22. February 2023
Parameters:
Water hardness 16 – 18 dH,
Flow rate 1.65 m3/h
Functional description:
The DHTECO device was installed in a pumping station where drinking water was continuously circulated in a tank. The fluctuation range of the water supply is between 1 and 2.5 m3/h. The decision for 1.65 m3/h was made after evaluating the consumption profile
ROI was 10 to 12 months
Savings (service, spare parts):
In the 1st year up to 20%
In 5 years 200%
Conclusion:
Before installing the DHTECO device in the area under study, the customer had to constantly maintain and repair the pumps and replace them frequently. Therefore, the annual costs were high. After the positive test results, the customer decided to purchase and install the DHTECO device to ensure maximum efficiency of the pumps and reduce overall costs.
