1. Scelta di materialiHFL - 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 per pannelli ed elementi strutturali di tipo 304, oppure tipo 316 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

Batteria BACBatteria di scambio principale

  • La batteria è costruita con tubi continui in acciaio di prima qualità, ed è zincata a bagno dopo la fabbricazione. Progettata per il libero drenaggio del fluido e una pressione d'esercizio massima di 10 bar, conformemente alla PED. Testata ad aria compressa a 15 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.

Optional stainless steel coils are in type 304L or 316L.

Optional finned coilHFL dry finned coil

  • The dry finned coil is constructed of minimum 4 circuits of staggered copper tubes with aluminium plate fins.
  • In galvanised steel casing with access door and enough space for inspection.
  • Designed for free drainage of the fluid and maximum 10 bar operating pressure according to PED. Pneumatically tested at 15 bar.
  • In combination with a flow control package including a 3-way valve, temperature sensor and piping.

3. Air movement systemHFL fan drive system

  • With motor-driven centrifugal fan and a V-belt drive, sized for dry operation as standard.  You can easily remove the entire motor base for proper belt tensioning to ensure constantly correct belt alignment. Together with the heavy duty fan shaft bearings this guarantees optimal operational efficiency.
  • Centrifugal fan(s) are forward-curved and nearly noiseless. Overcome external static pressure! Use sound attenuators and duct work etc. for air intake/discharge with no loss of thermal performance!
  • Our drift eliminators 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 internal access.

4. Water distribution systemHFL water distribution system

  • A header and spray branches with wide non-clog plastic nozzles, secured by rubber grommets.
  • A spray water collection section with:
    • dry sloped basin with circular access doors
    • wet water basin out of the air stream including easy to lift-out anti-vortexing strainer, make up, rectangular access doors.
  • Close coupled, bronze fitted centrifigal spray pump with totally enclosed fan cooled (TEFC) motor at connection end of the unit. Bleed line with metering valve installed from pump discharge to overflow.
  • The electric water level control package maintains a constant water level in the cold water sump independent of cooling load changes and water supply pressure variations.
