Product Detail


Holtop 3D high efficient cross counter-flow heat exchanger is a unique recuperator specially designed for air-to-air heat recovery in balanced ventilation systems. It is a true breakthrough in ventilation technology, making it possible to recover and efficiently reuse generated energy for heating or cooling rooms while optimizing the ventilation that is so crucial for a healthy indoor climate. 

Holtop 3D high efficient cross counter-flow heat exchanger can be used in almost any ventilation system to maximize indoor comfort and air quality while substantially reducing basic energy requirements and costs. This benefits end-users by increasing their well-being and reducing their energy bills. And, reducing the need for fossil fuels also benefits our environment.

Features of 3D High Efficient Cross Counter-flow Heat Exchanger

The appearance structure of the 3D counterflow high-efficiency heat exchanger is a hexagonal core, and the internal main channel structure is a triangle. This structure can fully ensure the maximum heat exchange area. The frame material of the heat exchanger is ABS, and the core material is special resin. This material has the characteristics of high thermal performance, good air tightness, tear resistance, oxidation resistance, and mildew resistance.

Working Principle 

When the indoor temperature and humidity are different from outdoor, the two-way differential air stream will transfer energy and dampness, which call energy recovery.

In the counter-flow heat exchanger, airflows are passed by each other along with parallel special resin plates in a counter-flow direction. This allows achieving higher temperature efficiency than using crossflow heat exchanger core. Two neighbor special resin foils form a channel for fresh and exhaust air streams. Heat is transferred when the partial air streams flow crossly and partial air streams flow counter through the channels, and the fresh airflow and exhaust airflow are totally separated.

Ultra-high Heat Recovery Efficiency

The air flows counterflowly to extend the heat exchange time and make heat transfer more thoroughly. The heat recovery efficiency is up to 95%.
