WL32D aeroclimatiseur pour autobus électrique — gestion thermique intégrée
Thermal management file TM-WL32D | The largest electric-bus roof unit in the WL-D family: high-capacity cabin cooling plus battery thermal-management integration.

1. Beyond Cabin Cooling — Thermal Management
For a 10.5–12.0 m electric bus, the AC system does double duty: it cools the cabin and supports the battery thermal-management loop. The WL32D is sized at 24 kW standard / 32 kW maximum cooling with 6,000 m³/h evaporator airflow — capacity headroom that lets the same thermal system serve cabin comfort without starving the battery cooling circuit.

3. The Compressor Core
The WL32D uses a horizontal variable-frequency scroll compressor (Copeland-type) — the same technology class trusted by major EV bus builders for its quietness and efficiency. Driven through a CV800-D032 frequency converter, it modulates capacity to match both cabin load and battery-loop demand.
