What makes this Insulated the right choice?
Two piece 375 Litre GRP Water Tank - Insulated (25 mm) Full WRAS approval
Manufactured to meet BS7491 Parts 1 and 2, using the highest quality GRP materials, ensuring a long service life with minimal maintenance requirements. Grey colour as standard (other RAL or BS colours are available at additional cost). Only materials of the highest quality are used along with a highly efficient manufacturing processes. This combination ensures that these tanks are of the highest quality available.
All internal surfaces, including the lid, have an Isophthalic white gel coat layer which provides a clinical smooth surface which will not support the growth of microbiological organisms. This gel coat layer is reinforced by the main GRP laminate, which provides the main structure of the tank body. The materials used are of the highest quality and applied with exacting production standards to assist in prevention of osmotic blistering. Further reinforcement is provided by square section steel tubing with fully welded corner joints. Steel reinforcement ensures that the softening and general deterioration encountered with timber supports is avoided, thus providing full structural reinforcement for the life of the tank.
After the CFC free PU foam insulation and the steel reinforcement are fitted, the GRP outer skin is then applied. This ensures that both insulation and reinforcement are fully encapsulated and protected from external conditions. The whole tank is then coated with a tack free grey polyester gel coat layer. This ensures that the tanks are suitable for all locations and weather conditions, and can be located outdoors as standard. Where access is a limiting factor and our one piece GRP tanks are unsuitable, a two piece tank could do the trick. These tanks are manufactured in two or more horizontally split sections, which are then assembled once the restriction has passed. In a nutshell, a one piece tank in two or more bolt together sections.
All the components including sealant and fixings for the joint flange are supplied with the tank. The assembly of this range of products could not be easier and should not prove difficult for any competent mechanical services engineer. These two piece tanks allow utilization of the more cost-effective one-piece type tank format, where a considerably more expensive sectional tank would traditionally have been supplied.
The Encapsulated Baseboard will come moulded into the internal base of the tank to become part of the tank's construction and overall strength of the base. This will benefit the tank if it's on uneven surfaces or positioned on raised supports. It will not come supplied as a separate item
