Helen is developing a smarter, carbon-neutral energy system that enables everyone to produce, use and save energy with respect for the environment. Helen aims to achieve 100 percent carbon neutrality in energy production by 2035.

The challenge
Helen was one of the first energy customers to take Sulzer Sense into use in their district cooling plant in Helsinki after it was launched in 2019. The system monitors the condition of two vertical pumps and motors.

The system consists of one gateway designed for industrial conditions, located in the process area, and six sensors installed in the bearings of the monitored equipment. The devices are battery powered and operate in a wireless mesh network.

The solution
The condition monitoring system was installed right after the pumps were commissioned. The assembly of the sensors was quick and effortless, with only a very short downtime, and did not require any special skills from the installer. The mobile app provided by Sulzer for the deployment of the system is straightforward and easy to use.

Sulzer Sense measures vibration and temperature every 30 minutes. Access to this information is granted only to persons authorized by the customer. The gateway is connected to the Internet / Sulzer’s cloud service via a cellular connection. The monitored devices are within a radius of about five meters from each other. This allows for an excellent network and the use of a single gateway.

"The system has worked well in a challenging environment for over a year now. Its measurement results are well in line with our own measurements" Ida Eskman, Mechanical Engineering Specialist, Helen Oy.

Customer benefit

  • In addition to the advantages of continuous monitoring, one of the most significant benefits to the customer is the access to detailed equipment information such as spare parts lists and product documentation through the service. For maintenance and repair work, there is no need to look in the archive for instructions and drawings.
  • Sulzer Sense is suitable for all pumps, agitators, mixers and motors regardless of the type or brand in all industries.
  • The operating status of the equipment can be remotely monitored 24 hours a day, seven days a week.
