Our BT2 buffer tanks add heating or cooling capacity to non-potable, closed-loop systems where the peak demand would otherwise exceed the ability of the system to satisfy it. They are found with low-mass boilers, geothermal systems, and large-scale environmental control systems.
As a chilled water buffer tank in an air conditioning or refrigeration system these tanks help satisfy demand when cooling loads are low by drawing from the chilled water they hold. This avoids the need for a full system start, which reduces equipment wear and overall energy consumption.
As a hot water buffer tank the BT2 provides both thermal mass and thermal storage to a system. The thermal mass helps stabilize the water temperature while the thermal storage provides capacity during periods of low demand. This reduces the number of boiler starts and need for full system operation.
The BT2 series is designed for storage capacities to 1,000 gallons as standard. All buffer tanks are provided with an internal inlet deflector (CW) or flow partition (HW) and are available with a fully insulated and jacketed exterior. Installed in a system, the BT2 reduces cycling, improves temperature control, and helps provide for a more even response to system demand.
