What Günsu does

Günsu Enerji Sistemleri Ve Konfor Tesisleri San. Tic. A. Ş. is a privately held Turkish engineering and construction firm headquartered in the Antalya Organized Industrial Zone that delivers turnkey pool, aquapark, and spa/wellness infrastructure primarily to the hospitality industry. Its offering spans design, supply, installation, and commissioning of swimming pools, Olympic and ornamental pools, water park attractions, Turkish baths, saunas, steam rooms, and related comfort facilities, alongside recurring revenue streams from pool chemicals, Legionella-control biocides, dosing systems, water treatment equipment (softening, filtration, reverse osmosis, ultrafiltration, wastewater), and industrial cleaning and hygiene products under sub-brands including Ante, Eponol, and Cappel Bio.

The company's technical base rests on composite and fiberglass manufacturing through the Fipol joint venture with Polin Waterparks (established 2004, 52,000 m² facility in Antalya OSB) using Hand Lay Up, Spray Up, RTM, Vacuum Infusion, and Pultrusion techniques, complemented by in-house R&D for wave-pool and automation systems as demonstrated on the 2022 Aqua Terra project in Moldova. In 2024 Günsu launched the Akıllı Su Takip Sistemi (Smart Water Tracking System), an IoT-based monitoring and automated dosing platform marketed to deliver up to 20% water savings in hotel pool operations.

Commercially, Günsu operates a direct enterprise sales model through six regional offices across Turkey (Antalya HQ, Muratpaşa, Alanya, Manavgat, Bodrum, Istanbul), targets enterprise hospitality buyers via project-based custom quotes and recurring chemical/equipment supply, and supports lead generation through industry trade fair participation, online inquiry forms, and industry-association training programs. The company holds ISO 9001, ISO 14001, and ISO 45001 certifications, and was recognized as a finalist at the World Architecture Festival 2024 in the Hotel & Leisure category for its role in the Scorpios Bodrum project.
