Instantaneous domestic hot water production unit for AICFX buffer tanks, with integrated control of up to four modules.
SANIBOX is GSI’s instantaneous domestic hot water (DHW) production module, designed for use with AICFX thermal storage tanks. Thanks to its stainless steel plate heat exchanger and high-efficiency electronically controlled primary pump, it converts the stored thermal energy into instantaneous domestic hot water without directly storing DHW inside the unit—ensuring continuous comfort and scalable performance, with cascade operation of up to four modules.

The SANIBOX range includes five sizes—80, 125, 150, 200, and 260—all featuring a standardized footprint and available as a single unit or in cascade configurations of up to four units.
Integrated DHW Recirculation Without Primary Pump Operation
The DHW recirculation loop operates independently of the primary pump. During recirculation-only operation, the primary pump remains off, reducing electrical consumption compared to systems with separately managed recirculation.
Flow Rates up to 260 l/min, 1,040 l/min in Cascade
Available in five sizes from 80 to 260 l/min, SANIBOX units can be combined in cascade configurations of up to four modules, delivering a total flow rate of up to 1,040 l/min. A scalable solution for applications ranging from small residential buildings to hotels and commercial facilities.
Seamless Integration with AICFX Thermal Storage Tanks
SANIBOX harnesses the thermal energy stored in AICFX buffer tanks (500 to 2,500 litres), maximizing thermal stratification and overall system efficiency, particularly when paired with heat pumps.
Programmable Controller with GSI CLOUD Connectivity
Equipped with a controller featuring a graphical display and Ethernet port, SANIBOX is ready for remote monitoring, supervision, and technical support through GSI CLOUD via CLOUDBOX.
SANIBOX
Instantaneous domestic hot water (DHW) production module for use with AICFX thermal storage tanks, available in cascade configurations of up to four modules.
SANIBOX is an instantaneous domestic hot water (DHW) production module designed for use with AICFX thermal storage tanks. Thanks to its stainless steel plate heat exchanger, it uses the thermal energy stored in the primary circuit to produce DHW only when required, eliminating the need to store domestic hot water inside the unit.
The electronic controller manages heat transfer between the thermal storage tank and the DHW circuit, maintaining a stable outlet temperature while optimizing overall system operation. Intelligent control of the primary circuit also enhances thermal stratification within the storage tank, improving system efficiency, particularly when combined with heat pumps.
Designed for residential, commercial, and multi-residential applications, SANIBOX provides a reliable solution for instantaneous DHW production, even under high demand. It ensures continuous hot water availability, outstanding comfort, and consistent long-term performance.
