AF Thermal Stores
The Arbe AF series of thermal stores are utilised to store heating water produced by an external heat source such as a CHP, heat pump or a biomass boiler, in closed circuits. The vessels are supplied plain as standard with material options available as below. Vessels can also be supplied with baffle plates, dividers and sparge pipes where required.
Arbe supply 3 off types of AF vessels, including standard and bespoke models:
AF-PV Range – Thermal stores for systems with various heat input circuits, available as a standard design
AF-RM Range – Multi-functional vessel with various heat inputs and DHW production for small systems
AF Range – Traditional thermal stores with multiple connections to suit various system designs. The AF range of vessels are bespoke to each application
The AF range of vessels are generally supplied with 4 off system connections and other connections as listed in our brochure. The vessels is also supplied with 3 off sensor connections for use with equipment such as CHP units or biomass boilers. The AF models are split into 2 types and either type can have additional fittings supplied such as sparge pipes, directional flow baffle plates and any other requirements for any specification.
AFT – Carbon steel shell, open design
AFP – Carbon steel shell with baffle or divider plates
Vessels are available with plain carbon steel, galvanised steel or stainless steel shells
We can also design and manufacture thermal stores up to 125,000 litre capacity, designed in accordance with various codes such as PD5500, supplied with full certification and CE marked where required.
Our standard range of thermal stores are designed and manufactured to the latest standards and are fully compliant with the Pressure Equipment Directive.
AF-PV Range of Thermal Stores
Thermal stores for systems with various heat input circuits, available as a standard design. The AF-PV vessels fitted with coils can be utilised as system separation vessels whilst having multiple heat inputs.
AF-RM Range of Thermal Stores
Thermal stores for systems with various heat input circuits, available as a standard design. The AF-PV vessels fitted with coils can be utilised as system separation vessels whilst having multiple heat inputs. The AF-RM vessel also has an additional coil for the generation of potable hot water making it an ideal solution for factories or other applications where a small amount of hot water is needed for sanitary requirements.
AF Range of Thermal Stores
The AF range of bespoke thermal stores are generally designed to suit each application, with connections and dimensions bespoke to the requirements. The AF thermal stores can also be designed to operate at higher working pressures and temperatures, with full certification as required.
Efficient Thermal Store Design
In an ideal world, a thermal store being used on a system with a CHP or a biomass boiler would be designed to be tall and thin, with a height:diameter ratio of 3:1 to aid with stratification, ensuring the CHP or biomass boiler operates efficiently and correctly.
Where this is not possible, the ARBE AF range of thermal stores can be fitted with baffle plates, in either vertical or horizontal orientations, so a thermal store can be designed to suit any site constraints. The baffle plates separate the cold and hot zones making it operate the same as a standard vessel by creating stratified sections.
The image below is of a horizontal vessel with a centralised baffle plate to ensure correct operation of the heat source it is being connected to.
