1. Scelta di materialiHXC - Costruzione

  • Acciaio zincato a bagno di forte spessore viene utilizzato per i pannelli dell'unità esterna e gli elementi strutturali che presentano la protezione anti-corrosione Baltiplus
  • L'esclusivo rivestimento ibrido Baltibond è disponibile come opzione. Un rivestimento polimerico ibrido che assicura una vita utile più lunga, pre-applicato a tutti i componenti in acciaio zincato a bagno dell'unità. 
  • Acciaio inox opzionale tipo 304L per pannelli ed elementi strutturali, oppure tipo 316L per applicazioni estreme.
  • Oppure l'alternativa economica: una vasca per l'acqua fredda in acciaio inox per il contatto con l'acqua. I componenti principali e la vasca stessa sono in acciaio inox. Gli altri elementi sono protetti dal rivestimento ibrido Baltibond.

2. Elemento di scambio termico

Sistema esclusivo e brevettato di trasferimento termico: dotato di flusso combinato tramite batterie di scambio termico e pacco di scambio.

Batteria di scambio principale

  • Sezione batteria per unità HXCLa batteria di scambio principale è costruita con tubi continui in acciaio di prima qualità ed è zincata a bagno dopo la fabbricazione.
  • Progettata per una pressione d'esercizio massima di 23 bar, conformemente alla PED. Testata ad aria compressa a 34 bar
  • All hot dip galvanized and stainless steel coils are delivered with BAC's Internal Coil Corrosion Protection, to ensure an optimal internal corrosion protection and guaranteed quality.

Try our HXC coil options:

  • Multiple circuit coils (split coils) for your halocarbon refrigerants, maintaining individual compressor systems. Or use it for compressor jacket water or glycol cooling. 
  • Stainless steel coils are in type 304L or 316L. 
  • High pressure coils are designed for 28 bar operating pressure and pneumatically tested for 40 bar. Hot-dip galvanized after fabrication.

All coils are designed for low pressure drop with sloping tubes for free drainage of fluid.

Finned coil

  • The 6-row dry finned coil is constructed of stainless steel 304L in a staggered triangle tube arrangement and with pre-coated aluminium high density fins.
  • Designed for maximum 23 bar operating pressure according to PED.

Fill BACross fill

  • The patented and factory-tested BACross fill with integrated drift eliminators certifified by Eurovent. Optional BACross fill bundles with handles for quick and easy removal and cleaning of the fill. The bundle includes individual sheets which are easy to dismantle for inspection and cleaning, eliminating the need for frequent fill replacement.
  • In self-extinguishing plastic, which will not rot, decay or decompose.
  • For operation above 50°C, try our optional high temperature fill, usable with spray water up to 55°C.

3. Air movement system

  • HXC fan system features two corrosion resistant sheaves, belt and motor. Together with the heavy HXC dampers duty fan shaft bearings and the BAC Impervix motor, this guarantees optimal and year-round operational efficiency.
  • Low kW and noise axial fan(s) in corrosion resistant aluminum, encased in fan cylinder. 
  • Modulating air inlet dampers are constructed in galvanised steel with air-tight, opposed blade design and proportional modulation through beams.
  • Air flow control package includes a pressure transmitter (ships loose for on-site installation), damper actuators and intelligent damper controllers.
  • Our drift eliminators in the coil section come in UV-resistant plastic, which will not rot, decay or decompose and their performance is tested and certified by Eurovent. They are assembled in easily handled and removable sections, for optimal coil access.
  • Easy removable UV-resistant plastic combined inlet shields at air inlet. Sunlight block to prevent biological growth in tower, air filter and water splash-out stop.

4. Water distribution system

FXV-D spray systemThese consist of:

  • Spray branches with wide non-clog, plastic, 360° distribution nozzles secured in grommets. Overlapping spray pattern for complete coil wetting.
  • A sloped cold water basin with large hinged and inward swinging access door and internal walkway.
  • Anti-vortexing strainers and make up both easily accessible from air inlet side.
  • Close coupled, bronze fitted centrifugal spray pump with totally enclosed fan cooled (TEFC) motor. Bleed line with metering valve installed from pump discharge to overflow.
