SPI CIRCUMPOLAR with heat recovery and heat pump
Developed entirely in-house by AHT, SPI CIRCUMPOLAR sets a new standard for decentralised cooling infrastructure in the retail sector. 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.
“Our goal with SPI CIRCUMPOLAR was to rethink how hydronic systems are built and installed,” says Andreas Uitz, Department Manager Global Product Management at AHT. “The result is a fully modular solution that simplifies complexity, reduces installation barriers, and scales effortlessly – from small stores to large supermarket environments.”
Key Benefits of SPI CIRCUMPOLAR:
• Modular and configurable: Designed with functional building blocks that can be adapted to support heat recovery, connection to dry coolers, or heating distribution (e.g., floor heating, buffer tanks, fan coils).
• Flexible installation: Can be wall-mounted, floor-standing, or ceiling-mounted – ideal for retrofits or space-constrained environments.
• Compact and transportable: Delivered on a Euro pallet and fits through standard doors – simplifying logistics and on-site handling.
• Open integration: Compatible with AHT’s Active Monitoring System (AMS) and third-party controllers, making it a truly open system.
• Energy optimisation: Supports direct and indirect heat recovery and connection to air or brine heat pumps for enhanced sustainability.
Proven in Practice
While the broad market rollout is just beginning, SPI CIRCUMPOLAR has already been successfully installed in several retail locations across Europe, proving its concept in live environments and demonstrating real-world value in terms of handling, performance, and system integration.
The product’s modular approach is protected under a patent, underscoring AHT’s leadership in technical innovation and its commitment to developing refrigeration solutions that evolve with the industry’s needs.
