The new membrane-based Enthalpy Heat Exchanger will bring new thresholds in efficiency, effectiveness, and simplicity, making it an ideal choice for core energy recovery solutions in modern ventilation systems.
Enthalpy heat exchanger means both heat and moisture transfer in a fixed membrane-type heat exchanger. Enthalpy heat exchangers are of two types, plate-type heat exchangers and membrane-type heat exchangers. Membrane heat exchangers are the desired option in ventilation systems where any ‘circulation’ of air is unwanted. The incoming and outgoing airstreams are entirely separated, and no moisture or odor is transmitted.
The DRI EcoERV HEX will come in both crossflow and counter-flow options.
Counter-flow heat exchangers are primarily used in ventilation and air-conditioning systems and are particularly suitable for controlled ventilation of residential buildings. In the counterflow heat exchangers, the channels are arranged in the opposing air flows to maximise the heat energy exchange.
Crossflow heat exchangers have higher spacing between the plates than in counter-flow models. In these heat exchangers, the air channels are arranged so that the air flows cross over one another.
Core energy recovery solutions a membrane core is one component inside an ERV/HRV—not the entire energy recovery solution.
A membrane enthalpy heat exchanger uses a specially engineered semi-permeable membrane to transfer heat and moisture between exhaust and fresh air streams. The membrane allows energy exchange while keeping the two airflows completely separated, while preventing direct mixing of the two air streams.
In a counterflow membrane core, supply and exhaust air move in opposite directions, maximizing heat recovery efficiency. In a crossflow membrane core, the air streams cross each other at right angles, offering a compact design with reliable energy recovery performance for a wide range of HVAC applications.
These membrane cores are widely used in hospitals, commercial buildings, schools, offices, shopping malls, residential buildings, restaurants, and ventilation systems where fresh air and contamination-free operation are essential.
DRI membrane cores offer high heat recovery efficiency, moisture transfer, minimizes cross contamination , low pressure drop, minimal maintenance, energy savings, improved indoor air quality, and compatibility with both crossflow and counterflow ventilation systems.
