DD540-E

All-electric double deck AC system

The DD540-E is a compact AC unit specifically designed for electrically driven double decker buses. Particular attention was paid to lightweight and energy-efficient components as well as performance and ease of installation.  

The product with integrated compressor and inverter convinces with a small space requirement, high safety and maximum reliability.

Highlights

Low Life-Cycle-Costs

  • Low energy consumption due to low overall weight (lightweight components and aluminium housing)
  • Long lifetime due to brushless EC blowers and fans

Environmentally friendly

  • Safety against leakage due to less piping and integration of components, e.g. compressor and inverter, in the unit
  • Outstanding COP of 2.3 due to energy saving design and components

Easy installation

  • Integrated components and reduced piping simplifies the installation process

Comfort & Safety

  • Individual and independent temperature control for upper and lower deck
  • A broad voltage range covers any of the requested applications
  • With the implementation of the sealed inverters, all maintenance parts, like fans, blowers, etc are at 24V level.
