At the ISK-SODEX Istanbul Fair held at the Istanbul Expo Center between 22–25 October 2025, DOGU HVAC welcomed visitors to its booth for four days under the theme “DOGU HVAC: Innovating Today, Sustaining Tomorrow”
At this year’s exhibition — which saw a 40% increase in international visitors compared to previous years — Doğu İklimlendirme presented its products designed with good technology for the future of nature, people, and its employees in a 396 m² exhibition area.
Throughout the fair, one of the highlights was the new-generation DKS Air Handling Unit, equipped with a rotary heat recovery system, DX cooling coil (3000 m³/h capacity), and a SIEMENS automation infrastructure. Certified by Eurovent and produced specifically for the fair with T2 and TB2 performance values, the unit drew considerable attention along with Four Season by DOGU-branded VRF Systems.
Another standout product was the environmentally friendly ECRH Rooftop Package Unit, operating with R32 refrigerant. With its custom design tailored to the conditioned environment, the unit offers heat recovery systems, fully automatic control, economizer dampers, and free-cooling functions, delivering high efficiency, low energy consumption, and superior comfort.
In addition, the FHR-T Floor Type Heat Recovery Unit, compliant with ERP 2018 regulations, and the CFHR-U Universal Type Counterflow Heat Recovery Unit, offering three installation options, stood out with their patented designs. These units enable recovery of up to 94% of the thermal load from exhaust air.
Another notable product in the same group was the Classmate School-Type Heat Recovery Unit, which can effectively ventilate indoor spaces without duct connections, thanks to its integrated return air grille and specially designed supply diffuser, providing high energy efficiency.
One of the most remarkable innovations at the fair was the HOME HW Heat Pump Heat Recovery Unit with Hot Water, produced for the first time in Türkiye by DOGU HVAC and launched at ISH Frankfurt 2025. With its integrated heat pump, the unit provides high-efficiency fresh air ventilation for residences up to 100 m², while its 200-liter integrated tank meets the domestic hot water needs of a family of 4–5 people.
Using R290 (Propane) refrigerant with a low Global Warming Potential (GWP), the system reduces carbon footprint with an environmentally conscious approach. Its compliance with European standards attracted great interest, reflecting Doğu İklimlendirme’s commitment to sustainable technology.
Additionally, the EPP Home and steel-cased HOME series units, featuring fully recyclable EPP body structures and ERP 2018-compliant design, stood out among residential-type heat recovery solutions, earning positive feedback for energy savings and improved indoor air quality.
Commenting on the company’s strong presence at the exhibition, DOGU HVAC General Manager Mr. Seckin Tuncer ERDOGMUS stated:
“As in previous years, our booth received an exceptional level of interest this year as well. During the fair, we welcomed visitors with a team of 67 staff members on the first two days and 50 on the remaining days. Once again, we proudly experienced the joy of being part of this industry with our continuously growing and specialized team. I must emphasize that behind this successful exhibition lies the dedication and teamwork of our outstanding employees.”
