ATREA

What ATREA does

ATREA s.r.o. is a Czech private limited company headquartered in Jablonec nad Nisou that designs, manufactures, and distributes heat recovery ventilation (HRV) and air handling units under the DUPLEX brand for residential and commercial/industrial customers. Its core technology centers on proprietary cross-flow, counter-flow, and rotary heat exchangers delivering up to 93% thermal recovery efficiency, complemented by an in-house control system supporting Modbus TCP, BACnet, and KNX building automation protocols. The portfolio spans air-flow capacities from 100 m3/h (residential family homes) through 15,000 m3/h (civil and industrial buildings), with specialized lines for schools (29 dB(A) units), large kitchens, apartment blocks, and indoor pools, plus Master Therm-branded heat pumps and thermal storage solutions distributed as part of an integrated HVAC offering.

The company operates from a 20,000 m2 owned manufacturing facility backed by an internationally accredited in-house testing laboratory, employs 350 people, and serves customers in 30 countries with a 25+ year continuous presence in Germany. Revenue is generated through hardware sales of ventilation units and consumable aftermarket filters (cartridges and textiles sold direct via eshop.atrea.cz), supplemented by professional services including mandatory authorized commissioning, project design support, and warranty/maintenance. Go-to-market is primarily channel-led through a structured network of project design partners, certified installation firms, and authorized service technicians coordinated via a Partners Zone portal, augmented by regional technical-commercial representatives covering distinct Czech territories. International distribution is handled through resellers, with a new branch opening in Finland in May 2026 to anchor northern European expansion.

ATREA's competitive positioning rests on multiple international certifications (Passive House Institute, TÜV, CE, Eurovent, ErP 2018, EAC, VDI 6022), premium component sourcing (EBM Papst fans), product compactness (170 mm ultra-thin units), and very low noise operation. The closely-held ownership structure (founder Petr Morávek; CEO Daniel Morávek) and absence of disclosed external funding point to a profitable, organically-financed mid-market industrial business rather than a venture-backed growth-stage company.

Scale indicators7 records

Recent moves7 records

Expansion highlights6 records

Broad incumbents

• Aldes Group: French indoor-air and ventilation group with a much broader HVAC portfolio than ATREA, including residential HRV, ducting, and IAQ solutions. It competes in ATREA's commercial and kitchen-ventilation verticals as a broader incumbent rather than a focused HRV specialist.

Direct peers

• Vents (Ventilation Systems JSC): Large Eastern-European ventilation manufacturer with broad ranges in fans, AHUs, and HRV units. Comparable SKUs across residential and commercial segments, with overlap in Czech and neighbouring CEE markets where ATREA operates its partner network.
• Dantherm Group: Danish HVAC manufacturer owned by EU-backed industrials, with ranges in air-handling, heat-recovery, and dehumidification units. Comparable technology portfolio and European specification footprint position Dantherm as a direct competitor in commercial HRV tenders.
• Blauberg Group: German/European ventilation manufacturer with single-room and central HRV units serving residential and light-commercial projects. Comparable mid-market positioning and export footprint in CEE and DACH regions.
• Swegon Group: Swedish-owned indoor-climate specialist covering ventilation, air-conditioning, and building automation. Comparable product depth and European installer-channel reach make Swegon a primary competitor for ATREA in commercial and educational DUPLEX applications.
• Zehnder Group: Swiss-listed specialist in heat-recovery ventilation and indoor climate, with a European manufacturing footprint and strong specification presence in residential HRV. It is the closest functional competitor to ATREA across the DUPLEX product family and target applications.
• Brink Climate Systems: Netherlands-based HRV specialist serving residential and small-commercial segments across Northern Europe. Brink is a focused direct peer in the same Passive House / low-energy residential niches where ATREA's compact DUPLEX Flexi-V and family-house SKUs compete.
• Inventer: German ventilation manufacturer specialising in decentralised and central heat-recovery units for residential and small-commercial applications. Direct overlap with ATREA's decentralised school / office range and family-house DUPLEX products.
• Systemair AB: Swedish-listed ventilation manufacturer with a pan-European production and distribution network across residential, commercial, and industrial air-handling units. It directly competes with ATREA's mid-range DUPLEX commercial line and has the scale ATREA lacks.
• Vallox (now part of Vallox & Finervent): Finnish ventilation manufacturer focused on residential HRV and demand-controlled ventilation. Vallox is a particularly salient peer given ATREA's announced 2026 Finland branch entry and shared expertise in cold-climate ventilation efficiency.
