APOLLO Lake Heat Exchanger system overview

Built for Durability

Constructed from premium AISI 316 stainless steel, this heat exchanger is engineered to withstand corrosion and mechanical stress, ensuring reliable, long-term performance. Its robust design guarantees a maintenance-free solution for your geothermal system.

Silent & Efficient

Unlike traditional dry coolers, this system operates without any moving parts or fans. It runs silently and passively, requiring minimal upkeep while providing maximum efficiency as a thermal bridge between your heat pump and the natural water source.

Sustainable Geothermal

By using a natural body of water as your primary heat source or sink, this exchanger significantly lowers your energy consumption and carbon footprint. It is the perfect interface for a low-carbon, high-performance geothermal system.

Seamless Integration

Designed to seamlessly replace traditional ground loops, this product connects directly to your APOLLO geothermal system's closed-circuit hydronic piping. Its compact form factor and simple submersion design make installation straightforward and efficient.
