Hengxing abstract

We offer sectional tanks that are made from hot pressed moulded panels to British and European Standards. Although there is no gel coat, the isophthalic resin rich inner surface is ideal for storing wholesome water. WRAS approved products. (G16.1)

Tanks constructed from panels can be built in spaces with restricted access.

Panels

Panel sizes currently offered are:

• 1 metre square
• 1 metre by 1/2 metre
• 1/2 metre by 1/2 metre

All sizes are available either plain or 40mm pre-insulated.

Access Hatches

All tanks come with a raised access hatch which is secured by 4 stainless steel fixings with a special finger-friendly top to enable the access hatch to be opened. To complete the requirement a seal is located on the underside of the access. This seals the top from the ingress of dirt and moisture. The access can be modified to be hinged and lockable, if required.

Raised Ball Valve Box "AA" and "AB" Air Gaps

To maximise capacity or to offer a type "AA" or "AB" air gap, a valve box can be included in the lid, thereby allowing a valve with a drop arm or an Aylesbury KA/KB valve to be fitted. The standard valve boxes for sectional tanks are 300mm in height with other heights available on request.

When a type "AB" air gap is needed, a slot is cut in the tank (of a size dependant on inlet valve size), covered with a specially moulded shroud that incorporates a screened mesh, and with a catchment tank that can then be plumbed into a discharge overflow. For type "AA" air gap the screened mesh is omitted.

Divisions

Tanks can be divided into compartments with stainless steel internal RHSs and cleats. Any divided section of a tank should not remain empty for more than 7 days to preserve the torque setting of the structure.

Insulation

Pre-insulated panels use zero ozone depletion polyurethane foam which is then covered with a waterproof skin. Phenolic foam insulation is also available to special order.
