Innovative project to recover heat from ammonia

A project to recover heat from superheated ammonia for central heating (CH) and domestic hot water (DHW) was implemented at a company in the food industry. This project was successfully implemented together with the engineering and construction company Projandspaw. This is a company with extensive experience in the implementation of industrial systems, covering a diverse range of industries, from pharmaceuticals and heating to refineries and the oil and gas industry.

Use of ammonia detectors

A key safety feature of the project was the use of JUMO ammonia detectors to detect leaks in the circuit. The Jumo ammonia sensor consists of a glass pH electrode and a reference electrode, housed in an electrolyte separated from the medium by a membrane. The operating temperatures of the sensor range from 0 to 50°C, and with a low-temperature electrolyte from -8 to +30°C.

Precise measurement and data analysis with the ammonia regulator

For data reading and analysis, the client chose the JUMO AQUIS 500 pH ammonia regulator due to its exceptional features:

• Accuracy and reliability: The AQUIS 500 pH ensures precise measurement of ammonia concentration in solutions, which is essential for proper control of industrial processes. The device is known for its stability and resistance to interference, guaranteeing reliable measurement results.
• Wide measurement range: The AQUIS 500 pH offers a broad measurement range, suitable for various applications, from wastewater monitoring to chemical process control.
• Ease of use: The AQUIS 500 pH is equipped with an intuitive menu and graphic display, making operation and configuration simple. It also includes automatic calibration and temperature compensation functions, further simplifying the user experience.
• Durability: The AQUIS 500 pH has an IP67-rated housing, making it resistant to harsh environmental conditions, such as high humidity, dust, and dirt.

Benefits of heat recovery

The ammonia heat recovery project has brought a number of benefits to the food company:

• Significant heating cost savings: Recovered heat covers a significant proportion of the building's heating needs, reducing energy bills.
• Reduction in CO2 emissions: By using waste heat, we reduce our use of fossil fuels, which in turn leads to a reduction in greenhouse gas emissions.
• Improved energy efficiency: The heat recovery system increases the energy efficiency of the factory, meaning less energy is wasted.
• Increased safety: Heat recovery from ammonia eliminates the need to burn additional fossil fuels, which reduces the risk of fires and explosions.

Safe heat recovery with NH3 ammonia detector - summary

The project to recover heat from superheated ammonia for central heating and hot water is an example of an innovative approach to energy management in the food industry. Thanks to the use of state-of-the-art technologies, such as Jumo ammonia meters and the JUMO AQUIS 500 pH controller, it was possible to achieve significant energy savings, improve efficiency and safety, and reduce CO2 emissions. The collaboration with Projandspaw proved crucial to the success of the project, opening up new perspectives for future, equally innovative initiatives.

We sincerely thank Projandspaw for its cooperation in the above project and are confident that our collaboration will continue in the future. We are already planning further joint projects in which we will be able to build on our mutual strengths and achieve even more.
