Best Water Tank Manufacturer


Formerly known as Killarney Plastics, Tricel is one of the leading Water Tank Manufacturer, renowned for crafting durable water tanks made of GRP (glass reinforced plastic).

Founded in the early seventies and following the initial success and growing service demand, the company moved to a new site and constructed its first small factory in the 1980s.

A great deal of operational experience gained over the years enabled the company to develop a number of innovative and unique manufacturing methods and processes that produced high-quality products.

The reputation of Tricel within the engineering and technical development sector flourished and, in time, led Tricel becoming the leading water tank manufacturer that it is today.
