Filter pump station SPI POLARBASE

Overview
SPI PolarBase is AHT's patented modular pump station designed for Semi Plug-In (SPI) Waterloop systems. Its modular architecture allows configuration for SPI operation, heat recovery, dry cooler integration and building heating distribution while enabling flexible installation and maintenance.

Modularity & Customisation
The unit's modular design permits capacity scaling, addition of functions and future upgrades. Configurations support SPI Waterloop system operation, heat recovery circuits and interfaces to building heating/cooling distribution.

Installation Flexibility
SPI PolarBase can be floor standing or wall mounted. Modules can be installed as connected sets or separately to suit site constraints. Each module is sized to pass through standard doors for narrow-access installation.

Interoperability & System Integration
A single connection point consolidates SPI cooling, freezing, heating and monitoring. SPI PolarBase is compatible with the AHT Active Monitoring System and third-party monitoring platforms. It integrates with dry coolers, heat pumps and building heating distribution systems to meet project requirements.

Advantages for Customers

• Fast on-site installation without a separate machinery room.
• Simple maintenance and straightforward capacity scaling.
• Designed to address practical retail and commercial refrigeration challenges.

Heat Recovery
Use refrigeration system heat to support space heating or hot-water preparation. With reversible heat pump operation, SPI PolarBase can contribute to building climatization strategies and reduce heating costs.

Optimization
Modules are specified according to system capacity to optimise SPI Waterloop system performance and energy efficiency.
