TOPAZ is a hybrid dry cooler with adiabatic precooling that dissipates the heat energy dry into the atmosphere. Without water treatment and without spraying water into the air flow, the coolant is cooled down to temperatures that are lower than the ambient air temperature. If the outside temperature rises, the humidification is switched on. With ambient air temperatures of up to ca. 23°C, the dissipation of heat is made by dry cooling. Bacteriological growth and pollution, as well as deposits in the heat exchanger are here prevented by the daily draining off the humidification water and the drying of the humidifier. The energy-saving motor and the low water consumption by recirculation also contribute to the low operating costs. The simple access through a rollup door and the parallel, vertical arrangement of the heat exchangers make servicing possible without dismantling the motors and fans.

Advantages of precooling through humidification of the supply air

No water treatment necessary
Very high switching point from wet to dry operation (approx. 23°C)
Low water outlet temperatures
Adiabatic cooling below the ambient air temperature
No dirt or deposits in heat exchanger
No chemicals (biocide, hardness stabilizers, corrosion protection) required

Technical characteristics

Supplied as “plug and play“, ready to connect devices
Performance control: always attempts to reach the optimal operating point

Easy maintenance

Internal access through complete opening
Maintenance free EC-Fans

In June 2018, the two renowned cooling tower manufacturers GOHL and KTK KÜHLTURM have grown together into an economic and legal entity. Both brands with their core competencies are to be maintained, strengthened and expanded.
Both brands GOHL and KTK KÜHLTURM KARLSRUHE have been standing for outstanding cooling tower quality for many decades - GOHL for whirl sintered series products, KTK for stainless steel cooling towers in almost every dimension - standard sizes as well as special constructions.

The consistent use of high quality materials and components, the continuous optimisation of our products and procedures, as well as our outstanding customer orientation in all corporate divisions are fundamental elements of our philosophy.
All cooling towers are produced to order. We process the metal sheets directly in an integrated system, implementing all steps from initial 3D-drawings to CNC-controlled machining. Flexible production means we are able to meet the specific requirements of our customers.
GOHL-KTK is a component manufacturer whose portfolio is designed to offer the right solution for every cooling task. We produce cooling towers to match practically any application. Our systems are used in nearly all areas of water recooling.

HIGHEST STANDARDS – CONTINUOUS ENHANCEMENT
We continuously work to enhance and match our models to meet the demands of today and tomorrow. Simultaneously, we are constantly developing new methods for optimising our product line. Examples of this include tank floors with a fall, or alternative designs of stainless steel droplet separators / tube heat exchangers.

EFFICIENCY AND HYGIENE
Our engineers had started working on the topics of efficiency and hygiene from the very beginning. In light of our company's broad portfolio of wet, dry and hybrid equipment, we are able to offer the most efficient one out of these system solutions with the lowest carbon emissions.

TECHNOLOGY
We pursue new avenues of design, based on our experience from delivering 60,000 cooling tower cells to customers in 35 countries.

DRY COOLER WITH ADIABATIC PRE-COOLING – A revolution in cooling technology: does not require water conditioning, produces no aerosols, and has a very high switchover point.
BIOZID-FREE HYBRID COOLING TOWERS WITHOUT RECIRCULATION OF SPRAYING WATER
EC VENTILATORS – The latest technology: energy savings of up to 30%, very quiet, straightforward regulation when used as axial and radial fans.
DTC ECOTEC - Innovative design: Flawless integration of components and optimized air distribution maximize efficiency of the system. Straightforward accessibility and a reduced number of components keep service expenses
FULLY WELDED COOLING TOWERS meet the most rigorous of demands on durability and hygiene thanks to being made entirely of stainless steel, their straightforward full-chemical cleaning and superheated steam cleaning. They are the first choice among hospitals and in the food & beverage industry.
