Partnership EcooSol – Sontex SA: Working together to develop solar installations on a regional scale.


eccosol sontex a 1

The EcooSol cooperative, based in Sonceboz-Sombeval, was officially founded on 29 June 2021 to promote the installation of photovoltaics and electric mobility in the Bernese Jura and its surroundings. Its aim to provide technical support and assistance with financing or operation to an entrepreneur, a municipality or an association wishing to equip itself with solar installations and participate in the energy transition.

Sontex SA has been strongly involved in the creation of this cooperative and will carry out a pilot project. The objective is to install 600 m2 of solar panels on the company’s roof, which will provide an annual electricity production of 140 MWh. The installation will then cover a quarter of the factory’s electricity needs with a self-consumption rate of more than 85%. Construction will start in autumn 2021 and the plant is scheduled to be commissioned in spring 2022.

Sontex SA is very grateful for the creation of EcooSol and the involvement of the municipality of Sonceboz-Sombeval, other companies and the population of the region.  The solar panel project on its roof will help increase the production of “green” energy in the region with competitive prices per kilowatt hour and we look forward to the start of this project in the coming months.

COVID-19 Pandemic communication, 02.11.2020


Dear partner,

After several months, it was thought that the virus was disappearing and life was returning to normal but our hopes have unfortunately not been fulfilled. The virus is still among us and will immediately take advantage of any lessening of our efforts.

With strongly rising numbers of cases and hospitalizations, many countries have now considerably reduced social life again. Even if the situation is not comparable to the one this spring, we have to be prepared for a longer period with restrictions and reduced activities.

Sontex has done everything possible to be ready in such a case as well. Our employees wear masks at the company; our warehouses are full so as to temporarily bridge any interruptions to supply chains and home office workstations are set up and are used extensively. Our production is running in 2 shifts and sometimes even at night to meet the current extremely high demand.

Whatever happens over the coming weeks, we will do everything possible to serve you and be there for you.

We wish you and your loved ones good health and a degree of calm in these uncertain times!

Management communication


Dear partner, the worst phase of the pandemic in Europe is now thankfully behind us. We will all do our best to ensure there are no further waves of infection. Thanks to the huge commitment of our staff and the best efforts of our suppliers, we were able to continue production without interruption and to guarantee a more or less regular process across the logistics chain. Despite this, we were sadly unable to avoid additional delays over the last few weeks and wish to apologise for this. We are committed to ensuring that, from now on, you will experience the normal Sontex again.

To date, we have had no diagnosed corona virus cases within the company and are happy that the safety and health measures taken contributed to this. The measures continue to be implemented in the factory until further notice. At the beginning of June, all staff who were still working partly from home will return to the factory for the most part and will be able to work as a team on new products and services.

We would like to thank all our partners for their patience and their great support during these difficult and challenging times. We look forward to meeting you in person again soon. And soon we will hopefully be able to enjoy a good meal together again.

Stay healthy! See you soon!

Sontex SA

Olivier Carnal. CEO                                     Patrick Grichting, CMO

COVID-19 Pandemic communication


The Corona virus pandemic is affecting us across all areas of life, starting with our own health – in family life, at work and not least in our leisure time. This requires patience, mutual understanding and time.

According to information from the Swiss government, we too have taken important precautions with regard to the Corona virus (SARS-CoV-2), primarily to protect the health of our employees, customers, suppliers and partners.

Due to the current situation throughout Europe and the situation which is changing hourly, it is difficult at the moment to predict what changes will occur in the coming days for us and our customers. We are committed to maintaining our operations and delivering on our promises to customers. However, these events are not without consequences. Our suppliers are currently experiencing the same situation as we are and are having difficulty meeting our needs. Many of our employees are in the process of organising their personal and family situations while others belong to risk groups and are temporarily unable to work at the company. It is therefore inevitable that longer delivery times will occur.

We stay in close contact with our customers and partners in order to focus the remaining resources on the essentials and to satisfy all your requirements as much as possible. We would like to take this opportunity to thank you very much for your constructive cooperation.

Although we are forced to slightly reduce our production volume, we will do our utmost to continue to provide you with the best possible service.

RED (Radio Equipment Directive)


On the 13th of June 2017 the RED (Radio Equipment Directive) 2014/53/EU will definitely replace the past R&TTE 1999/5/EC. In addition to a stronger harmonisation, it is the target of this directive to assure that radio communication is done in an effective and efficient manner while avoiding unnecessary disturbances. Our products have been tested and the documentation has been adapted accordingly in order to comply with the new directive.

Supercom 323 and 327 radio modules – Sontex SA’s contribution to a peaceful sleep


According to statistics most fires start during the night and asphyxiation by smoke is one of the main causes of death.

The radio modules Supercom 323 and 327, developed in partnership with Ei Electronics and approved by the KRIWAN Test Centre, allow remote inspection of the EI650FA smoke detector. A periodic remote reading of the smoke detector enables to check, in real time, the functioning of the sounder and the battery. In the event of a malfunction it is possible to react quickly and thus ensure the safety and well-being of the tenants.

For more information about the radio modules Supercom 323 and 327 please see Communication Modules.

New range of reading systems


For many years Sontex SA has dedicated its know-how to innovative communication systems. The well-known and in many applications established Sontex 433 MHz radio system is now complemented by the wM-Bus and OMS 868 MHz radio system. Sontex SA offers a range of devices – heat meter, heat cost allocators and additional radio module – that work with the unidirectional wM-Bus system. If requested, an AES128 encryption key to protect your data can be inserted into the devices from both radio systems at the factory. With the Supercom 637 and Supercom 647 reading systems as well as dedicated software it is now possible to make a simple, fast and efficient reading at any time.
