Certification, assessment and inspection of air recuperators

Air heat recovery (rekuperation) is an essential component of modern buildings – from family homes and apartments to office and industrial facilities. To ensure safety, efficiency, and long-term reliability, professional testing and certification of air heat recovery units are necessary.

What Is Air Heat Recovery

Air heat recovery refers to the process of reclaiming heat from extracted indoor air. The heat exchanger transfers energy from outgoing warm air to fresh incoming air that is supplied back into the interior. This allows for continuous ventilation while significantly reducing heat loss and lowering heating costs.

A well-designed and properly functioning heat recovery system provides:

continuous fresh air supply without the need for frequent window ventilation,
energy savings thanks to recovered heat from extracted air,
stable humidity levels and reduced risk of mold and condensation,
increased comfort and a healthier indoor environment.

Why Certification of Air Heat Recovery Units Matters

Certification of air heat recovery units verifies that the device meets required technical parameters and standards. The outcome is an independent confirmation that the unit operates safely, efficiently, and in compliance with legislation.

Main Benefits of Certification

Verified quality and safety – the unit is assessed for operational safety, construction, and function.
Guaranteed performance – declared values such as efficiency, airflow, and noise levels are independently tested.
Energy efficiency – certified units support meeting building energy requirements.
Simplified approval and documentation – certification helps with compliance during project approval and inspections.
Customer trust – certified devices demonstrate quality and reliability.

What Our Assessment and Certification Includes

As part of the certification process, we conduct comprehensive testing and evaluation of air heat recovery units according to applicable standards and technical requirements.

Typical Tests and Evaluated Parameters

measurement of airflow rates and pressure losses,
determination of heat recovery efficiency,
air leakage tests and assessment of unwanted air bypass,
noise and vibration evaluation,
electrical and mechanical safety checks,
inspection of product workmanship, labeling, and documentation.

Based on the results, we prepare detailed test reports and, if requirements are met, issue the corresponding certificate. This document confirms that the unit is suitable for use in the intended types of buildings and operating conditions.

Who the Certification Is Intended For

Manufacturers and importers – to prove conformity and product quality on the market.
Designers and construction companies – certified devices simplify HVAC planning and project approval.
Investors and building owners – certification provides confidence in safe and efficient performance.
Facility managers – ensures long-term reliable and compliant operation.
