Control and safety devices - key elements of the installation

In the world of hydraulics and electricity   control and safety devices play an extremely important role . They ensure the safety and efficiency of systems. They ensure their proper functioning. At Onninen, we understand their importance perfectly. That is why we offer a wide range of high-quality products. Our range includes renowned brands. These include Afriso, Syr, Wika, Flamco Meibes and Volt. Each of them is renowned for its reliability and innovation.

Our clients often ask about selecting the right devices.   It is crucial to precisely define the needs and specifics of the installation . Many factors must be taken into account. These include the type of system, working conditions and required parameters. In our daily practice, we provide individual advice. We help select the optimal solutions for specific applications.

Types of control and safety devices offered by Onninen

Our offer includes a wide range of products. It includes:

  • Manometric cocks
  • Heating and standard pressure gauges
  • Siphon tubes
  • Immersion sleeves
  • Temperature sensor pockets
  • Two-way and three-way taps
  • Contact pressure gauges

Each of these devices has its own unique application. Manometers are used to measure pressure in installations . Manometer cocks allow them to be safely disconnected. Siphon tubes protect manometers from high temperatures. Immersion sleeves and sensor pockets protect measuring elements.

In the case of large industrial projects, we often recommend contact pressure gauges. They allow for automatic process control. We recently used such a solution in a production plant. It provided precise pressure control in the steam system. The effect was a significant improvement in energy efficiency.

Criteria for selecting control and safety devices

When selecting the right devices, there are several key aspects to consider:

  • Installation operating parameters (pressure, temperature)
  • Type of medium
  • Required measurement accuracy
  • Environmental conditions
  • Compliance with standards and regulations

Our experience shows that precise selection is essential . Many customers ask us about the differences between the different types of devices. We explain that, for example, standard manometers work well in typical installations. Contact gauges, on the other hand, are ideal for process automation.

In the case of office reorganization, we most often recommend compact solutions. They work well in limited spaces. For the chemical industry, we recommend devices resistant to aggressive media. We often come across the question of energy efficiency. In such situations, we propose intelligent control systems.

Practical applications of control and safety devices

Control and safety devices are used in many industries . In the food industry, they ensure the safety of production processes. In the power industry, they monitor the operation of boilers and turbines. In residential buildings, they provide comfort and energy savings. We recently implemented a project for a hospital. We used an advanced system for controlling medical installations there. It ensured the safety of patients and staff.

In our daily practice, we see how important reliability is. That is why we focus on products from proven brands. Afriso is famous for its precise pressure gauges. Syr offers reliable safety valves. Wika is synonymous with innovation in pressure and temperature measurement. Flamco Meibes specializes in complete solutions for heating systems. Volt provides high-quality assembly accessories.

Onninen recommends a comprehensive approach to securing installations. We combine various devices into coherent systems. We thus provide optimal protection and control. Our specialists provide professional advice at every stage. We help in the selection, installation and configuration of devices. We also provide after-sales support and service.

We invite you to familiarize yourself with our full range of control and safety devices. Our experts will be happy to answer any questions. They will help you choose the optimal solutions for your specific needs. Take advantage of our experience and knowledge. Provide your installations with the highest level of safety and efficiency.
