Thermal Storage

Bespoke Buffer Tanks

Mibec are able to offer bespoke designed but cost-effective buffer tanks for large heating and cooling projects. Ideal for a range of applications including larger biomass projects, district heating, CHP (Combined Heat & Power) systems and chilled water systems (e.g. in large data centres).

A Buffer tank retains heat for later use and can supplement the heat source when demand is high or store heat when demand is less. Stored heat can be immediately accessed without the heat source needing to get up to temperature; this can be very useful for maintaining a constant output.

All of these Mibec tanks are tailor-made to suit the exact customer requirements. Tanks and vessels of up to 200,000 litres are possible with our bespoke design and manufacture service (although 100,000 litres is often the practical limit for ease of transportation to site). It is perfectly possible to even manufacture small bespoke tanks from only 100 litre capacity if the customer is unable to find an off-the-shelf solution to meet their exact requirements. Tanks at around 10,000 litre capacity are most common and these tend to be used in conjunction with heat sources at around 1 mega watt output as typically seen in commercial RHI projects.

Mibec bespoke buffer tanks are precision built using only the highest quality materials. They are typically manufactured from mild steel (usually 5mm thickness / SJ275R grade for the main body and 6mm for the dish ends) and rated to 3 bar (6 bar if required). The tanks are finished with a rigid foam insulation jacket to minimise heat losses (initial thermal K factor 0.023 W/m K. Initial U-value 0.22 W/m2 K) and a metal outer skin for increased durability during installation and in service. All bespoke tanks are individually tested to the European Pressure Equipment Directive (PED) before leaving the factory.

The tank specifications are fully customisable to meet the exact project requirements, for example baffles and coils can be added for linking to existing systems and heat loads. Flow and return connections can also be selected to meet the exact customer requirements with different sizes available with for example Female BSP threads or equivalent with flange connections.

If you are looking for that bespoke buffer tank solution please feel free to email or call our support department on 0330 053 8880 where one of our team will work with you to define your exact project requirements and provide you with a no obligation quote. When the specification for the project has been agreed our team will produce a technical drawing of the tank design for customer sign-off. Once the order is placed lead-time for delivery is only around 2-3 weeks.
