The HXC range of evaporative condensers are forced draft, combined flow and axial fan towers.
Key benefits include: maximum water savings, low refrigerant charge and no fogging.
Typical applications for this range of cooling towers are: industrial refrigeration applications, installations requiring water savings and installations requiring a low mist level.
Description
General presentation
Unparalleled water savings
It offers different operating regimes throughout the year. During the summer, the HXC works as an evaporative condenser. In other periods, the louvers that modulate the air intake increase the air flow and the condensing capacity in dry mode, as well as the water economy. Dry operation in winter is possible.
Fog-free operation
The combination of sensible, adiabatic, and evaporative heat transfer decreases the possibility of fog formation.
During the winter, HXC operates in dry mode, Dry operation.
Fog-free operation during wet operation due to the finned coil that reduces the humidity of the air rejected through the coil.
Low refrigerant charge
Smaller coil (due to the patented combined heat transfer system) means less refrigerant and lowers the operating cost of the whole system.
Low maintenance and easy inspection
Inspection and maintenance of HXC capacitors is carried out safely, with unrivaled indoor comfort
HXC evaporative condensers have a spacious interior area and easy access for inspection/maintenance.
Access to the inside of the tower is achieved by means of a large door, and the optional internal platform does not require the removal of water from the pool for inspection of the interior of the unit
Easy to inspect coil during operation both externally and internally via removable drop separators.
Easy to inspect the stuffing from the inside and via the removable air intake grills from the outside.
Bacross II patented filler sheets reduce dirt, allowing full inspection of the filler without disassembly. One can opt for BACross filler packs that can be quickly and easily removed for cleaning the filler.
Self-cleaning cold water basin and filling it above the inclined basin to wash away dirt and debris.
Removable anti-vortex suction filter cover.
Make-up system, drain and overflow easily accessible for inspection and cleaning.
Energy saving
Evaporative cooling PLUS unique combined heat transfer system for minimum system-wide energy consumption.
The axial fan uses half the energy of a similar centrifugal fan and achieves a huge capacity with a single cell: saving more!
Uses less water = lower water costs = lower water treatment expenses
Flexible operation
Unique and patented heat transfer system having both coil and filler, being suitable for applications with strict temperature requirements and thermal challenges.
Different corrosion-resistant materials are available, including Baltibond, a patented hybrid coating, to guarantee a long service life.
Single air inlet and outlet, condensers are suitable for most applications
Maximum safety in operation
HXC units are easy to clean and inspect, reducing the hygiene risk caused by bacteria or biofilm inside.
Air intake grilles prevent sunlight from entering the tower to prevent biological growth in the tower, filter the air and stop water splashing outside.
The patented BACross padding reduces fouling.
Eurovent certified drop separators prevent water droplets from reaching the air.
Operating principle
The first mode of operation
The process fluid (1) first passes through the fin coil (2) and then enters the primary coil (3), which is wetted by a spray system (4). When the dampers (5) are closed, the axial fan (6) blows air over the primary coil in parallel with the water spray flow. The evaporation process condenses the vapor into liquid (7). The sprayed water falls over the filler (8) where it is further cooled before reaching the inclined water basin (9). The spray pump (10) recirculates the cooled water to the spray system. The warm saturated air (11) leaves the tower through the droplet separators (12) behind the finned coil, where it picks up additional sensible heat.
Mode 2 of operation
If the ambient temperature is below the condensing temperature, the dampers will open. The air flow increases and the air distribution changes so that less air is drawn over the primary coil and filler. This improves sensible heat transfer and further reduces water consumption.
Mode 3 of operation
Completely dry operation is possible when the spray pump is turned off.
