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...

CAST RESIN TRANSFORMERS Product for indoor application OIL IMMERSED TRANSFORMERS Product for outdoor application DRY TYPE TRANSFORMERS Not inflammable REACTORS In case of breakdown AUTOTRANSFORMERS In case of engine start up

Cast resin transformers Avant-garde production processes and industrial concepts characterized by constant innovations allow to obtain a product with a longer life cycle from 3 to 5 years respect to analogous products on the market. This in due to the 50% reduced partial discharge level. This product is characterized by the following PLUS. Medium voltage surge arresters arrangement Rating plate can be placed as installation needs Greater cooling surfaces Design of clamps that allow a greater aeration and cooling of windings Under vacuum casting process, wich allows uniform distance between...

OUTDOOR PRODUCT

Oil immersed transformers Our production covers a wide power range, extending from 50 kVA up to 30000 kVA, with voltage classes from 1,1 Kv up to 145 Kv. The product is characterized by refiable production features common to all the EREMU production range. This product is characterized by the following PLUS: Separated boxes for high voltage and low voltage. Cooling fins with reinforcements to guarantee the transport Sealing covers of big dimensions that facilitate connections and inspections Filter press and drain valves to avoid long connection distances Identification plate can be...

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

Reactors The EREMU reactor is a current limiter in case of short-circuit in the system. It is for reason that its position is at the output power plants or at the input position in substations. The production range extends up to 6000 A with insulation classes up to 36 KV.

ENGINE START UP EVERY ENGINE START UP REPROPOSES A SITUATION OF SHORT-CIRCUIT A controlled start reduces twisting efforts, burns and the mechanical wear of the engine.

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.
