Our history

Depósitos Coballes, 1981-2015

"More than 30 years at your side, our beginnings"

 

1981  The  company was founded   in1981 with the current denomination of deposits COBALLES, SL. Its first location was in the town of A Guarda (Pontevedra), in a warehouse of 100 square meters. Our founders goal was to manufacture  tanks to produce hot water in the style of firewood kitchens, after detecting a need  in this market..Previously, the products used for this purpose had a much lower quality than  what is now available, since the existing products in the market at that time were made of galvanized iron. 

 

2015  Today we continue to be a dynamic and innovative company thanks to our extensive technical knowledge and experience,which we apply in every project. Each new product is  adapted for renewable energies  and customer´s requirements.

DEPOSITOS COBALLES MANUFACTURE PROCESS

DÚPLEX 2205 STAINLESS STEEL MANUFACTURING

  • The material used in the manufacture of our tanks & wáter heaters is DUPLEX 2205 stainless steel.
  • We have selected this steel becouse of its high resistance to corrosion, as well as is high mechanical resistance - much higher than the traditionally used for manufacturing - AISI 316 stainless steel.
  • DUPLEX 2205 ensures the absence of contamination in the water, in addition to the conservation of its organoleptic properties.
  • Sheathed electrical resistance: High resistance and durability as well as a quick replacement, becouse it does not require the draining of the water heater.
  • The quality of the materials used prevents corrosion, making unnecesary the use of magnesium anodes or cathodic systems.
  • Manufacture in-house

UNIQUE MANUFACTURING PROCESS

  • TIG Welding: The highest accuracy in welding, avoiding the presence of pores
  • Protected atmosphere Welding
  • Coil: our manufacturing process unique, as we make each coil in a single piece, avoiding intermediate welds.
  • Pickling and passivation by immersion: Deposits are submited to a process of pickling and passivation by immersion, as opposed to the wash surface, so we can guarantee their durability.
  • Insulation: our tanks are insuladed with HD polyurethane foam, resulting in Less heat loss = Greater energy efficiency
  • Double test: Once its manufactured, we submit tanks to a double test in efficiency and resistance.
