DRY COOLERS

Bora dry coolers

High-end dry coolers in V-shaped and horizontal design, featuring microchannel heat exchangers and evaporative pre-cooling

10-2000kW

PRODUCT OVERVIEW

Leading edge dry coolers for industrial and commercial applications

Bora dry cooler is a concentration of new heat transfer and HVAC technologies, including microchannel technology, evaporative cooling, and modern EC-driven fans. Bora dry coolers cover the application range up to 2MW and are available in two designs, with V-shaped and horizontal microchannel heat exchangers, and suitable for commercial, air conditioning, and industrial process applications.

 

The optional evaporative pre-cooling system offers substantial energy savings, increased capacity, and reduced noise emissions, and enables the use of Bora dry coolers at extremely high ambient temperature conditions without efficiency loss.

Efficient, cost-effective and quiet axial fans

Axial fans used in Bora design have outstanding characteristics in every respect, including performance and efficiency, weight, noise pollutions, and robustness.

EC technology is one of the key foundations of energy efficiency, and we equip Bora condensers with the latest EC motors which demonstrate impressive performance, low energy consumption, high torque, and durable design.

Comprehensive corrosion protection measures have been taken that allow the fans to be used in almost all climatic applications with outstanding operating reliability.

Unbeatable heat transfer and high corrosion protection

Microchannel technology provides Bora dry coolers with numerous benefits, including higher heat transfer rate, decreased fan power consumption, based on lower airside pressure drops, closer approach temperatures, smaller unit footprint, and reduced weight. The synergy effect is unrivalled performance and efficiency, lower system cost and reduced operating expenses.

 

High corrosion resistance enables a long lifespan for Bora dry coolers in seashore, aggressive, and chemically polluted atmospheres.

BOOSTS SYSTEM EFFICIENCY UP TO 30%

Evaporative pre-cooling

REDUCES COMPRESSOR WORK

Evaporative pre-cooling system provides cooling of ambient air before entering the heat exchangers. Even in humid environments, Bora dry coolers offer remarkable performance and expand the scope of operation of the cooling system. Equipping Bora dry coolers with evaporative pads results in significant energy savings of up to 30%.

 

The evaporative media of E•VAP™ based on water retaining finned aluminium plates designed for maximum evaporation: saturation efficiency reaches 90% and more at air velocities up to 2m/s. The internal geometry and special fin coating of evaporative media facilitate cleanliness of the evaporative media during the operation.

 

In order to achieve maximum efficiency and minimal water usage, the E•VAP™ pre-cooling system can be equipped with a pumping station which includes circulation pump, water treatment module, and control system with state-of-the-art algorithms that monitor ambient conditions and determine operation modes, ensuring the E•VAP™ system is only active when necessary. The fully automated water management system continuously monitors the water quality, drains the system and refreshes the water when mineral levels reach certain values.

Evaporative pads can be easily detached for maintenance and access to the heat exchangers for cleaning.
