Klimator and Saltera: road weather forecasts, salt control

Since March 2026, the products have been grouped under the Saltera brand: forecasts for each road section, connected road weather stations and control that sends the treatment directly to the spreader. Mesta has worked with Klimator since 2020. For Falköping spreaders, Saltera's forecast control is not listed as ready to use, but Saltera states that Falköping can be integrated.

About Klimator

Klimator was founded in 2001 by Torbjörn Gustafsson and Jörgen Bogren, who have a long research background in applied road climatology at the University of Gothenburg. The company is listed on Nasdaq First North Growth Market.

Klimator has two patented core innovations: the Road Condition Data (RCD) data platform, which produces road weather forecasts in real time and up to 18 hours ahead, and the AHEAD sensor technology, which reads the road conditions ahead of the vehicle in real time. On 5 March 2026, Klimator launched the Saltera brand for its winter maintenance products. The company behind it is still called Klimator AB.

The products under the Saltera name

The press release about the new name divides the offering into six parts:

• Saltera Road Status (RSI): decision support with current and upcoming road conditions and recommended actions, designed for decisions about when something needs to be done, what to do and how much salt or sand to use.
• Saltera IoT RWIS: battery-powered 4G road weather stations that measure road surface temperature, air temperature and humidity. The measurements are used in the forecast model.
• Saltera Dynamic Salt: sends the relevant treatment directly to the salt spreader.
• Saltera Adaptive Salt: a camera and laser sensor analyse the road conditions in real time and adjust the spreading accordingly. See AHEAD: camera and laser that read the road conditions.
• Saltera WMI (Winter Maintenance Index): brings forecast, action and result together in one place, for follow-up.
• Saltera API: gives access to Klimator's road and weather data in the customer's own systems.

From forecast to spreader

In what Klimator calls dynamic salting, the dose is planned for each road section. Compatible spreaders fetch the set points directly from RSI and apply them automatically. Klimator describes it as the treatment forecast being downloaded to the spreader, which acts on the forecast at the same time. The product page says that you can set your own safety margins for the dosage.

In 2024, Epoke launched a solution in which Klimator's road condition forecast is transferred to Epoke's EpoSat routes, so that the spreaders are controlled dynamically according to the forecast. Klimator wrote that this would help simplify a decision chain made up of the decision to start, manual control of the spreader and documentation of the treatment.

Saltera states on the product page that salt use can be reduced by up to 30 per cent. That is the supplier's own figure. What research says about the effect is covered in forecast-controlled gritting. In Næstved Municipality in Denmark, RSI is connected to BM System's operations platform; see the guide to BM System.

Falköping spreaders and Saltera

Saltera and Falköping describe the link differently:

None of these pages lists Falköping as ready to use with Saltera's forecast control. If you want forecast control on a Falköping spreader, you therefore need to check with Klimator and with us which solution applies to your spreader and your control system. Read about the control systems for the C, CL, CLC and TC spreaders and about data collection.

Christer Friggeråker of Friggeråkers Verkstäder sat on the reference group for the Swedish research project “Prognosstyrd dynamisk vinterväghållning”. The final report from August 2023 describes a first meeting about testing automated salt spreaders in the winter of 2023/24, at which Vaisala was considered able to send a forecast-based dose via BM System to a connected Falköping spreader. A similar arrangement was planned with Mesta and Klimator in Norway.

• On Saltera's product page for forecast-controlled spreaders (Dynamic Dosage), only Epoke is listed under “Redo att användas – spridare” (ready to use – spreaders). Saltera states that the system can be integrated with additional spreaders on request.
• Saltera's campaign page “Fem vägar” states that larger spreader manufacturers such as AebiSchmidt, Epoke and Falköping are “möjliga att integrera” (possible to integrate).
• On the product page for road-condition-controlled spreaders (Adaptive Dosage), Falköping / Friggeråkers is listed as a partner together with Epoke. That solution is in a test and evaluation phase.
• Falköping itself states that its forecast-controlled spreading has been developed exclusively for, and is available together with, Falköping's own control system and Panel PC.

Users in Norway

Norwegian users mentioned in the sources, mostly in Klimator's own press releases:

• Mesta: According to Saltera's customer page, the partnership started in the autumn of 2020 with a two-year evaluation agreement, followed by a four-year agreement in December 2022 covering use in all relevant winter maintenance contracts in Norway. In the winter of 2022/23, Mesta used salt forecasts from RSI in 23 areas, according to a Swedish research report. In 2025, Mesta ordered RSI for six new operating areas and just over 100 road weather stations. At the end of 2025, Mesta owned 11.15 per cent of the shares in Klimator.
• Vaktmesterkompaniet (Oslo, 2025): Dynamic Dosage connected to existing Epoke spreaders, together with IoT stations, RSI and Floating Car Data from Zeekit.
• Stian Brenden Maskinservice (2025): five-year agreement for dynamic salting, in which connected salt spreaders are controlled by the treatment recommendations from Klimator's system.
• Presis Vegdrift: three orders in 2026, including products for automated decision support.
• Statens vegvesen (the Norwegian Public Roads Administration) has run the pilot project “Ahead” with Mesta and Klimator in Sunnfjord and Salten, in which a laser, a camera and sensors on the snowplough truck adjust the amount of salt in real time.

Before you choose

Statens vegvesen states that it assesses the need for salting on the basis of observations from weather stations, inspections and weather forecasts, combined with local knowledge and past experience. Nor is Klimator the only forecast supplier: in the Swedish research project, SMHI, Vaisala and Klimator were the suppliers. See the guide to Vaisala.

Ask the supplier about the following before you decide:

• Which spreader makes and control systems are connected today, and does this apply to forecast control (Dynamic) or camera and laser (Adaptive)?
• How do the quantities from the spreader get into the documentation? What the maintenance contracts require is covered in GPS-controlled gritting.
• Which gritting material and which method suit the road network? See dry salt, pre-wetted salt or brine.
