The ETUBE cooling tower is a closed-circuit evaporative cooling solution designed to provide efficient and reliable heat rejection while keeping the process fluid separated from the ambient air and spray-water circuit.
The process medium circulates through a closed coil system, while the external coil surface is wetted with recirculating water. In counter-flow, the combination of efficient heat-transfer surfaces, optimised water distribution, evaporative cooling and powerful EC radial fan technology enables stable thermal performance with reduced energy consumption and a protected primary circuit.
Designed for demanding industrial and HVAC applications, the ETUBE cooling tower offers reliable operation, energy-efficient airflow control, simplified protection of the process medium and service-friendly access to the main internal components. Durable casing and material options support operation in a wide range of installation environments.

The process fluid remains inside the closed coil system and is not directly exposed to ambient air, spray water or airborne contamination.
Evaporative cooling enables efficient heat rejection and stable process temperatures close to the ambient wet-bulb temperature.
The separation of the primary and secondary circuits helps protect sensitive process fluids from dirt, biological contamination and uncontrolled water quality changes.
High-efficiency EC radial fans provide powerful, precisely controllable airflow with direct drive, reduced transmission losses and low maintenance requirements. The ETube can be adapted to different process media, temperature levels, flow rates and installation conditions.
Inspection access and a practical component layout support efficient maintenance and help reduce intervention time.
