WL26LY Aeroclimatizator pro omnibus montatus in tecto — Praeclarum architecturae unitatis divisae

1. Split Roof vs Integral Roof — The Design Choice

The WL26LY belongs to the LY split-roof family: the condenser and evaporator sections are laid out as independent sub-assemblies inside one long roof profile, joined by the refrigerant circuit rather than by shared ducting. This gives two practical fleet advantages — modular service access (either section can be opened and repaired without stripping the other) and copper-tube coils on both sides for maximum corrosion margin in humid climates.

3. Copper-Tube Coils — Both Sides

Unlike integral designs that use aluminium parallel-flow on the condenser, the LY family specifies copper-tube fin-and-tube coils on both condenser and evaporator. Copper gives higher corrosion resistance against road salt and coastal air, and — critically — the coils can be repaired locally by any refrigeration shop, whereas aluminium condensers must be replaced.

4. Fan Configuration — 6 + 4

Six ZHF283502 evaporator blowers distribute 4,800 m³/h across the full cabin; four LNF273107C condenser fans provide the idle airflow a split unit needs at bus terminals. The drive train pairs an FKX40-560K / 4PFCY compressor (550/650 cc) with a 2A/2B clutch and SPB belt.

7. FAQ Emptoris

Q1. Quale est vantagium del disegno LY a tetto diviso?

Sectiones condensatoris et evaporatoris independens significat accessum modularis ad servitium, et bobinae in tubis cupri utrinque praebent resistentiam superiorem contra corrosionem simul ac possibilitatem reparationis.

Q2. Ad quos autocarros WL26LY aptatur?

Autocarri et autocarri coachei inter 8,0 et 10,5 m longi, qui 28 kW requirunt — via communis ad meliorationem ab unitatibus classis 20 kW.

Q3. Quod refrigerans utitur?

R134a cum onere fabricae de 12,0 kg.

Q4. Est-ce que le compresseur est inclus ?

Kit completus cum compressore FKX40-560K/4PFCY, clavicula, cingulo et alternatore; optio sola pro tecto disponibilis.

Q5. Num coilae loco reparari possunt?

Ita — bobinae fin-and-tube in tubis cupri a quolibet officina refrigerationis curari possunt, aliter quam condensatores aluminium parallel-flow.
