Conflict minerals | As a global supplier of HVAC control solutions and fan speed control devices, Sentera has a policy of conducting business and operating within all regulatory guidelines.
After reviewing our processes and consulting our carefully selected material suppliers, some of the products supplied by Sentera do contain one or more of the 3T1G - Tin (Sn), Tungsten (W), Tantalum (Ta), and Gold (Au), also known to be conflict minerals. Sentera does NOT directly purchase any of these minerals from the DR Congo or its neighbouring countries and does not know the source.
Due to the complexity of the mineral supply chain, Sentera is unable to identify the origin for the minerals used in components and in our products. We are, however, asking our selected material suppliers to take reasonable due diligence in the supply chain to ensure that the minerals used are not sourced from conflict regions.
