Cooling Towers & Adiabatic Coolers

Erivac is proud to represent the Cofinair Group (Decsa, Gohl-KTK, and Jacir), a leading supplier of cooling towers, adiabatic coolers, condensers, and refrigerant coolers, providing cooling solutions and technology to businesses in various industries. With decades of experience and a commitment to innovation and quality, they have established themselves as a reliable partner for companies seeking efficient and dependable cooling solutions. 

Why Cooling Solutions Matter

In many industrial processes and manufacturing facilities, maintaining the right temperature and climate control is crucial for both product quality and efficiency. Overheating or undercooling can lead to production disruptions, increased energy consumption, and reduced productivity. Therefore, the choice of cooling solutions is of utmost importance. 


Cofinair Group's Product Range of Cooling Towers, Condensers, and Refrigerant Coolers

We understand that different industries and applications have varying cooling needs. That’s why Erivac, through Cofinair Group, offers a comprehensive portfolio of cooling towers, condensers, refrigerant coolers, and adiabatic coolers designed to meet diverse requirements and usage scenarios. Here are some of our top cooling tower lines:

Open Evaporative Cooling Towers for Clean Water  

Open Evaporative Cooling Towers are used when cooling requirements demand large water volumes and/or when cooling water must be at a low temperature. They use evaporation to efficiently cool water and are ideal for a variety of applications. Open-loop cooling towers have no specific water quality requirements. Some of Cofinair’s open cooling towers are specially designed for use with clean water. 

  • Evaporative Cooling Towers with Axial Fans and Forced Draft (KH Series)

   This series of evaporative cooling towers is designed for industrial use with low power consumption. They are cost-effective and offer reliable cooling. Often supplied as a solution fully in Stainless Steel for higher corrosion resistance, lower maintenance, higher availability and longer operational life.  

  • Evaporative Cooling Towers with EC Fans and Induced Draft (ZENIT Series)

   Erivac’s ZENIT series combines low noise levels, low power consumption, and a compact design to meet various HVAC and industrial cooling requirements. With frequency converter integrated with the fan motor the power consumption can be reduced to half if operating at 2-3 degrees below design wet bulb temperature. 

  • Evaporative Cooling Towers with Radial Fans and Forced Draft (S, ATM, TMR, WRD, KS Series)

   For HVAC and industrial use with low noise levels, this series of evaporative cooling towers is the perfect choice. They deliver high efficiency and reliable performance. 

  • Evaporative Cooling Towers with EC Fans and Forced Draft (DTC Series)

   Cofinair’s DTC series combines low noise levels and low power consumption, making them ideal for HVAC and industrial applications where energy efficiency is important. 

  • Evaporative Cooling Towers with Axial Fans and Induced Draft (TMA-EU, SQA, VAP, KAD Series)

   These cooling towers are designed for industrial use in limited spaces. They have a compact design and offer high-performance cooling. 

  • Crossflow Evaporative Cooling Towers (X TAR, TMX Series)

   This series provides better thermal exchange, low power consumption, and low noise levels. They are perfect for HVAC and industrial applications where efficiency and noise levels are important factors. 


Evaporative Cooling Towers for Impure Water, Process Water, or Wastewater

Our cooling towers for impure water are designed to handle water with high particle levels, which is essential for some industries such as paper, chemical, and petrochemical industries, among others. 

  • X-STREAM Technology

   Cofinair’s unique X-STREAM technology uses specially designed fillings that can handle extreme conditions in the air, higher particle levels, and in the water, a high concentration of suspended particles, compared to other types of fillings. This reduces clogging, improves thermal exchange, and extends the lifespan of the cooling tower. Installing these cooling towers in industrial environments with expected high levels of air pollution and dirty water is no longer a problem. 

  • Custom Options

   We offer a range of custom options, including various fan types, sound insulation, stainless steel construction, and more, so you can tailor your cooling solution for impure water to your specific needs. 

  • Closed-Circuit Evaporative Cooling Towers for Clean Water / Very Dirty Water

   Closed cooling towers are preferred, especially in situations where high-quality cooling water is required, such as for process equipment with narrow cooling channels. 

   In cases where process water or wastewater that needs cooling is so impure, with high dirt content, that Cofinair’s X-STREAM technology can no longer be used, evaporative cooling towers can be installed in a closed loop with clean water and heat exchangers specially designed for heat exchange with the dirty water. 

Adiabatic Coolers – No Aerosols and Significant Water Savings 

   These cooling systems are developed to: – radically reduce liquid losses from evaporation; – be entirely safe and not propagate Legionnaires’ disease (legionella); – not require water treatment before the cooler; and – be easy to maintain. 

   Adiabatic coolers are characterized by the spatial separation of adiabatic evaporation of water in the inlet air from the downstream dry cooler. The adiabatic evaporation process is time-limited and cools the inlet air as needed. This lowers the air temperature when ambient temperatures are high, such as in the summer. The downstream dry cooler removes process heat. 

  • Adiabatic Cooler with H-Shape (Topaz Series)

   Cofinair’s Topaz Series of adiabatic coolers is designed to be easy to maintain, with easy access to the inside of the equipment for tube bundle cleaning and potential fan disassembly. 

  • Adiabatic Cooler with V-Shape (Zyrco Series)

   Cofinair’s V-Shape adiabatic coolers require less installation space and are a cost-effective alternative to the Topaz series. 

Adiabatic Condensers (Onyx Series) 

   Adiabatic condensers are used for cooling systems that use ammonia as a refrigerant. These adiabatic condensers have low water consumption, no risk of propagating Legionnaires’ disease (legionella), no need for special water treatment, and easy maintenance due to their H-shape design. 

Evaporative and Adiabatic Condensers – The Most Efficient Way to Remove Heat During Cooling 

Cofinair can offer two types of equipment with condensers for industrial refrigeration: evaporative condensers (most efficient) or adiabatic condensers (energy-saving and without generating any aerosols). 

Evaporative Condensers for Refrigerant Cooling 

  • Refrigerant Cooling with Radial Fans (CFR-C Series)

   This product line of refrigerant coolers is specially designed for low noise levels. 

  • Refrigerant Cooling with Axial Fans (CFR-A Series)

   Cofinair’s refrigerant coolers with axial fans are designed to take up as little space as possible while having the lowest possible energy requirements. 

Options for Cofinair’s Cooling Towers, Adiabatic Coolers and Condensers

   There are many optional features available for Cofinair’s cooling towers, condensers, and adiabatic coolers that may be of interest to your specific needs and applications. Here are some of these options: 

  • Sound Insulation
  • Stainless Steel Construction – Special steel called X-Steel with better corrosion properties than SS316L
  • Surface Coating (Decsa surface coating or “Whirl Sintering” with corrosion class C5M)
  • Polyester construction, completely free from corrosion issues. 
  • Hybrid Cooling Towers – with condensers for outgoing air with evaporated water, applications for dry cooling are also possible. 
  •  Adiabatic coolers with drainable coil loops – Topaz series. 

Construction Materials 

Cooling towers are often exposed to extreme weather conditions and must therefore be made of corrosion- and weather-resistant materials. Whether you choose stainless steel or DECSA coating/Whirl sintering, you can be assured that our towers will last a long time.
