AHT modular pump station for waterloops
5th May 2025
AUSTRIA: AHT Cooling Systems has launched SPI Circumpolar – a patented modular pump station designed to deliver unprecedented flexibility, scalability, and integration for semi plug-in waterloop systems.
The SPI Circumpolar was developed entirely in-house by AHT and debuted at Chillventa last year.
AHT insists that as commercial refrigeration moves toward more efficient and sustainable technologies, this solution offers a future-ready foundation that adapts to customer-specific needs without compromising system integrity or rollout speed.
Modular and configurable, it is designed with functional building blocks that can be adapted to support heat recovery, connection to dry coolers, or heating distribution like floor heating, buffer tanks or fan coils.
It can be wall-mounted, floor-standing, or ceiling-mounted and its compact size enables it to be delivered on a Euro pallet and fits through standard doorways.
SPI Circumpolar supports direct and indirect heat recovery and connection to air or brine heat pumps for enhanced sustainability.
It is also compatible with AHT’s Active Monitoring System (AMS) and third-party controllers, making it a truly open system.
“Our goal with SPI Circumpolar was to rethink how hydronic systems are built and installed,” said Andreas Uitz, AHT’s department manager global product management. “The result is a fully modular solution that simplifies complexity, reduces installation barriers, and scales effortlessly – from small stores to large supermarket environments.”
