GOHL KTK

What GOHL KTK does

GOHL-KTK GmbH is a German manufacturer of custom-engineered cooling towers, headquartered in Durmersheim, Germany, and operating as the German subsidiary of the French COFINAIR Group. The company designs, builds, and services an extensive portfolio of products including open-circuit evaporative cooling towers (ECube/DTC/TMR-EC and KAD/TM-X series), closed-circuit towers (ERI/WRI), hybrid coolers (KAHV), adiabatic recoolers and ammonia condensers (TOPAZ/ONYX), and the CALOR heat recovery tower. Core technology is built around EC (electronically commutated) fan drives and the proprietary Wirbelsinterung corrosion protection coating, with products already compliant with EU ErP 2026/Ökodesign energy efficiency requirements.

The business model combines custom-engineered one-time equipment sales with multi-year service contracts covering inspection, sealing, coating, technical upgrades, and retrofits. Pricing is quote-based and project-specific, with retrofits (notably the ECube) yielding ROI under five years for customers. Go-to-market is direct enterprise field sales, with a regional sales team organized by German postal code areas and dedicated after-sales contacts covering DACH plus project exports to more than 100 countries. Customer segments are horizontal and industrial, including data centers (e.g., Leibniz-Rechenzentrum), paper, laundry, and broader industrial process cooling and building HVAC applications. The company employs 51-100 in Germany and is part of the 300+ employee COFINAIR Group operating five production sites across Europe.

Core offering

GOHL-KTK designs, manufactures, and services custom-built evaporative, hybrid, and adiabatic cooling towers and recoolers for industrial and commercial customers. Its portfolio spans open-circuit towers (ECube/DTC/TMR-EC, KAD/TM-X), closed-circuit towers (ERI, WRI), hybrid coolers (KAHV), adiabatic recoolers (TOPAZ) and condensers (ONYX), and the CALOR waste-heat-recovery tower. All systems are individually engineered and produced in Germany, and the company provides full lifecycle services including inspection, maintenance, sealing and coating, technical upgrades, complete renovation, new installation, and the ECube retrofit for upgrading existing towers.

Product overview

GOHL-KTK offers Europe's largest portfolio of evaporative, hybrid, and adiabatic recooling solutions, delivered as a modular product family supplemented by lifecycle services. The product line centers on open-circuit evaporative cooling towers (ECube/DTC/TMR-EC series with EC-technology, and KAD/TM-X axial-suction series), closed-circuit cooling towers (ERI stainless steel and WRI Wirbelsinterung-coated series), hybrid coolers (KAHV combining dry and evaporative cooling), adiabatic recoolers (TOPAZ) and condensers (ONYX for NH3/R717), and the CALOR heat recovery tower. Services cover inspection, sealing/coating, technical upgrades, complete renovations, new installations, and the ECube Retrofit for modernizing existing towers. All products are manufactured in Germany with high production depth.
