FAQs - Frequently Asked Questions

Below you will find the most frequent questions/problems and their solutions. You can click on the most popular FAQs or on the topic relevant to you. 


  • Can the defrost function of the ROFROST Eco also be used (in Winter) to defrost frozen pipes?

    No, the defrost function can only be used to defrost at specific points (under the tongs). Therefore it is not possible to defrost frozen lengths of pipe or systems.

  • What should one look out for concerning freezing with the ROFROST Eco in practice?

    If only one pipe is to be frozen then both jaws can be mounted side by side. This improves the freezing performance. It is important to ensure that both jaws are mounted together with no gap. If the device is stored at low (<0°C) or higher (>25°C) temperatures, the device must be attached to the power supply as soon as possible before use. The ventilators in the housing bring the device up to the operating temperature so that the performance of the device can be used to its ideal full potential. Avoid storage at low temperatures.To avoid a situation where the reducing inserts fall out easily when attaching the freezing jaws to vertical pipes, the freezing process should be started before attaching the freezing jaws to the pipe. The heat conducting paste will freezes the insert to the jaw, allowing the jaw to be positioned

  • Can the pipework or multi-layer composite pipes be frozen using the ROFROST Eco?

    No, plastic lines cannot be frozen. Plastic is a poor conductor. There is therefore the danger that the water in the pipes does not freeze. Multi-layer composite pipes can be frozen but with a much longer freezing time. Therefore the beeping of the ROFROST Eco CANNOT be taken here as an indication that the pipe is frozen!

  • When is the pipe frozen with the ROFROST Turbo?

    There is no 100% accurate way to indicate that the pipe is frozen. However, ROTHENBERGER offers, as is the only manufacturer to do this, three different indicators. o A thermometer: It lies easily seen above the freezing jaw. Based on experience the water is frozen for normal use and environmental conditions if the temperature indicator has shown -15°C constantly for at least 10 minutes (marked area in the thermometer). o Freezing time: There are details of the freezing times given in the cover of the device which are based on experience values. There is a safety factor built into the times quoted. This means that longer times were deliberately quoted as further security for the user. Build up of an icy coating: A clearly visible icy coating on the outside of the pipe is the indicator for freezing of water in the pipe. Apart from ROTHENBERGER there is no other manufacturer who works with an integral thermometer. We therefore offer a high degree of security when using the device.

  • Can the plastics pipes or MSR (multi-layer composite pipes) be frozen using the ROFROST Turbo?

    Yes, MSR can be frozen. Observe longer freezing times (freezing times at least double compared to copper and steel pipe). Yes, plastics pipes can also be frozen. The freezing process simply takes longer.

  • What is better when freezing using the ROFROST Turbo: Heat conducting paste or spraying the pipe?

    Both techniques avoid air pockets being trapped between the freezing jaw and the pipe (air pockets impair the freezing performance). Spraying on has some disadvantages in use: o the time factor: constant spraying of the pipe with water o cleanliness: Humidification / fouling of the whole area around the pipe (for example the wall)

  • How does freezing take place with the ROFROST Turbo on vertical pipes?

    On vertical pipes fastening or mounting takes place through connecting the hose in the lower area of the jaws. This avoids deposits of oil accumulating in the freezing jaws.

  • Why does only one freezing tong ice up on my ROFROST Turbo or why has the performance of both freezing jaw got worse?

    It is possible that compressor oil has accumulated in the freezing jaw or in the hoses. Hold both freezing jaws up high and run the machine for 10 minutes. This allows the compressor oil to flow out of the freezing jaws.

  • How does freezing take place with the ROFROST Turbo on plastic pipes?

    Wrap the plastic pipe with aluminium foil before attaching the freezing jaws. This can help accelerates the freezing process.
