ECO-SUSTAINABLE AND ENERGY-SAVING SOLUTION
Bora is a range of air-cooled condensers featuring microchannel heat exchangers, high-performance axial fans, and suitable for use with a wide selection of HFC- and HFO-based refrigerants. Bora condensers cover application ranges up to 2MW and available in two designs, with V-shaped and horizontal heat exchangers.
The optional evaporative pre-cooling system offers substantial energy savings, increased capacity, and reduced noise emissions, thus enabling Bora condensers to be used at extremely high ambient temperature conditions without efficiency loss.
The range includes a large number of models to select from: with V-shaped or horizontal microchannel heat exchangers, units with V-shaped or heavy-duty vertical evaporative pads, equipped with EC- or AC-motor fans and single or double refrigeration circuits, in standard or low noise configurations.

Evaporative Pre-Cooling
BOOSTS SYSTEM EFFICIENCY UP TO 30%
REDUCES COMPRESSOR WORK
E•VAP™ evaporative pre-cooling system permits a reduction in the temperature of air delivered to condensing coils even in hot and humid environments and expands the scope of operation of the condenser while remaining at the same level of efficiency. Equipping Bora condensers with evaporative pads results in significant energy savings of up to 30%.
The evaporative media of E•VAP™ is based on water retaining finned aluminium plates designed for maximum evaporation: saturation efficiency reaches 90% and more at air velocities of up to 2m/s. The internal geometry and special fin coating of evaporative media facilitate cleanliness of the evaporative media during operation.
In order to achieve maximum efficiency and minimal water usage, 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 the ambient conditions and determine the operation modes, ensuring the E•VAP™ system is active only when necessary. The fully automated water management system continuously monitors 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 condensing coils for cleaning.
Unbeatable Heat Transfer Rates and High Corrosion Resistance
Microchannel technology provides Bora series condensers numerous benefits, including higher heat transfer rate, decreased fan power consumption based on reduced airside pressure drops, closer approach temperatures, smaller unit footprint, and reduced weight. These benefits, as well as reduced refrigerant charge, result in lower system costs and reduced operating expenses.
Latest Generation Axial Fans
EFFICIENT, QUIET AND COST-EFFECTIVE 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 Bora condensers are equipped with the latest EC motors which demonstrate impressive performance, low energy consumption, high torque, and durable design.
Comprehensive corrosion protection measures have been taken to allow fans to be used in almost all climatic applications with outstanding operating reliability.
