Copper-Lined Storage Calorifiers
The Arbe ALC range of standard storage calorifiers are manufactured from carbon steel and copper. It is a design with a steel outer shell (pressure bearing) and a copper inner shell (for the potable water application). This ensures a long-lasting shell, which gives a product solution for installations where a copper shell is a specification-compliant requirement, especially where high pressures are involved.
The removable heater battery on each calorifier is manufactured to suit the required duty and the standard units are manufactured with brass tubeplates and with finned copper tube.
Each ALC calorifier is supplied with an anti-vacuum valve as standard and are suitable for vented or unvented systems.
The Arbe AL-CSS range of semi-storage calorifiers are a bespoke product that offer solutions for high output, fast recovery domestic water heating. As an alternative to the Arbe StorPlate package, the HevaCal AL-CSS unit has an integrated removable heater battery and is supplied with a circulating pump that takes water from the bottom of the cylinder, heats it up by passing the water over the heater battery and pushing it into the top of the cylinder, ready to be taken off to the system.
Arbe can supply the units c/w all primary controls and unvented kits.
Arbe design and supply sectional storage calorifiers which are ideal for instances where access into an existing plantroom is limited. Each calorifier is bespoke for the particular site requirement, with the size of the calorifier and the size of the sections designed to suit access.
The calorifiers are generally supplied with bolted sections and are re-assembled on site in final situ' ready for testing and operation.
The sectional calorifiers can be manufactured in stainless steel, copper-lined steel and galvanised steel to suit any specification, with working pressures to suit the project.
Standard Heater Batteries
The Arbe AL range of standard storage calorifiers have removable heater batteries fitted as standard to heat the water in the shell, with the primary medium inside the tubes. Our batteries are manufactured from either stainless steel or copper, depending on the application and requirements.
