The high-performing HRV RS300 is designed for applications where compact dimensions and high efficiency are essential.
To meet these demands, the unit features an elongated shape that reduces thickness, combined with an optimized channel design for enhanced airflow.
Compared to the RU300, the RS300 also offers a slightly improved pressure drop, contributing to even better overall performance.
Additionally, our resource-efficient manufacturing process ensures consistent quality and energy efficiency.
We are top brand of the year in energy recovery
In 2025, we were recognized as the top brand of the year in the field of energy recovery.

With ribs
Two ribs on opposite sides of the heat exchanger enable it to be guided into a groove, making installation and removal easy.
They also provide even better sealing for our heat exchangers.
With fire protection grids
To comply with specific fire behaviour requirements, our heat exchangers can be equipped with fire protection grids.
This enables them to meet the requirements of the German Institute for Building Technology (DIBt), for example, and achieve fire behavior class E in accordance with EN 13501.
With condensation drain holes
Defined points on the outer casing of the heat exchanger ensure controlled drainage of condensate, so that it is reliably directed into the condensate collection tank of the ventilation unit.
Our innovative CORE enthalpy and heat exchangers can be found in numerous ventilation systems around the world.

Generally, an enthalpy exchanger (ERV) fulfills the same function as a heat exchanger (HRV). It transfers the heat from the extract air to the supply air, or vice versa. But enthalpy exchangers also transfer energy from moisture thanks to their integrated, moisture-permeable polymer membrane.

CORE enthalpy and heat exchangers are designed for long-term operation and durability. Under normal operating conditions and with proper ventilation system maintenance, such as regular filter replacement and heat exchanger cleaning, the lifetime of a CORE enthalpy or heat exchanger can be up to 17 years or longer.
Yes. As a company, association, public institution or research institution you can order a sample and test the product using the contact form on this page.
Depending on the product type, the minimum order value for ventilation unit manufacturers is usually one pallet.
Yes. CORE provides ventilation unit manufacturers with technical data, documentation, and expertise to help them obtain certification and approval.
As we only sell our enthalpy and heat exchangers as components for ventilation units to ventilation unit manufacturers, we are unfortunately unable to do this. Please contact your ventilation unit manufacturer for the necessary support and spare parts. You can also order spare parts from retailers.

Under certain conditions, like low outdoor air temperature and a high humidity level of the extract air, condensation can occur. Therefor proper condensate management is recommended. Controlled flow rate and temperature ranges can keep the operation of the corresponding ventilation unit condensate free in a wide range.
CORE enthalpy and heat exchangers are made primarily of recyclable polymer materials. At the end of their service life, they can be disposed of according to local plastic or aluminum recycling regulations. We recommend contacting local waste management or recycling companies to ensure proper and environmentally responsible disposal.
