High density main


The High Density adiabatic condenser is a hybrid cooling system designed to avoid water waste and pollution. This makes it a more cost and resource-efficient alternative to cooling towers in industrial refrigeration systems, for example in the food and beverage industry.

Product Overview

High Density adiabatic condensers combine dry-cooling heat exchangers with hydroBLU™, Güntner’s pre-cooling system based on humidification pads, in one compact device. As long as the temperature in the cooling system doesn’t exceed a pre-set threshold, hydroBLU™ remains inactive and no cooling water is used. Once the threshold is passed due to a peak in load or ambient temperature, humidification of the pads is activated and dynamically adjusted by the intelligent control modules GHM and GMMnext. The resulting evaporation chills the air passing through the pads just enough to provide the required level of extra cooling.

By keeping cooling water consumption to the absolute minimum, High Density adiabatic condensers use up to 70 percent less water than comparable cooling towers. As the humidification pads dry during normal operation, no disinfection or other expensive chemical water treatment is necessary to ensure hygiene and efficient operation. Avoiding maintenance work, water waste and pollution in this way can easily amount to significant annual savings.

Benefits at a glance

Icon control


With Güntner’s intelligent control systems, an energy-efficient and resource-saving unit operation is guaranteed.
Icon water drop


With Güntner’s adiabatic pre-cooling and humidification pad system, operation at high ambient temperatures is ensured, at the lowest possible energy consumption.
Icon fluid


This unit works with all available refrigeration fluids and is optimised for use with natural refrigerants.
Icon fans


Maintenance-free, durable fans. Available in AC and EC technology, ErP-compliant, adjustable speed, in various sizes, optimal air and sound level properties.
Icon circles


Ensuring long service life, the coil prevents the refrigerant carrying tubes from coming into contact with the end sheets. This allows a contraction-free operation without the risk of tube damage, drastically reducing the chance of leaks.
