Product catalog summary
Company Overview
Eremu, S.A. has been in operation for over 50 years, specializing in the manufacture and repair of electrical transformers. The company expanded its product line to include battery chargers and power suppliers, primarily serving the naval sector. Eremu's business policy focuses on quality assurance, client communication, efficient service, and adherence to international standards such as CE and ISO-9001. The company has a strong presence in various markets including naval, railways, and power electronics.
Product Offerings
  • Cast Resin Transformers: Designed for indoor use, these transformers feature advanced production processes that extend their lifecycle by 3 to 5 years compared to similar products. Key features include enhanced cooling surfaces, medium voltage surge arresters, and a vacuum casting process for uniform winding distances.
  • Oil Immersed Transformers: Suitable for outdoor applications, these transformers range from 50 kVA to 30,000 kVA with voltage classes up to 145 Kv. They include features like separate high and low voltage boxes, large sealing covers, and reinforced cooling fins.
  • Dry Type Transformers: Ideal for environments where non-inflammability is crucial, such as refineries. They feature a clamping system with grooves and phase isolation for delta connection bars.
  • Reactors: Used as current limiters in case of short-circuits, suitable for both indoor and outdoor use. They support up to 6000 A with insulation classes up to 36 KV.
  • Autotransformers: Designed for engine start-up situations, these products offer controlled start-up to reduce mechanical wear and are suitable for both indoor and outdoor installations.
Design and Innovation
Eremu emphasizes innovative design features across its product range, such as improved aeration and cooling for transformers, and user-friendly maintenance features like accessible drain valves and dryers.

MV/HV transformers-3

PRESENTATION AND ACTIVITIES Eremu, S.A. was established more than 50 years ago as a firm dedicated to manufacture and repair electrical transformers. Aftewards, and due to complete a line of parallel necessities detected in our costumer´s environment, we enlarged our range of products with a line of elements associated to the others. A line of battery chargers and another of power suppliers constituted this new range basically. In both cases directed preferentially to our customers on the naval sector. At the moment our presence in the market is completely consolidated due to our firm bussines...

Dry type transformers In certain contexts like refineries or the petrochemical field, the non-inflammability becomes a factor of primary importance. The dry type transformer is the ideal product in these contexts thanks to the productiva technology and thanks to some special features such as: Clamping system with grooves Phase isolation for fixing the delta connection bars Interleaved disc windings

Autotransformers It is ideal product in the situations of engine start up that, as know, reproduces the conditions of a shortcircuit. AUTOTRANSFORMERS ALLOW A CONTROLLED START UP WICH REDUCES Twisting efforts Generating wear and breaches Generating machine stop To these advantages we have to add the benefits due to the functioning flexibility. This product is made for indoor and outdoor usage. If installed outside, it does not need particular protections against the contact or premises used for the installation. It reveals as a product that generates incredible cost savings.
