Product Overview
The DR1 is a high-capacity rooftop electric air conditioning system designed for trucks, motorhomes, campers, off-grid vehicles, machinery, marine applications and custom builds. On the 200s, the plastic ends on the side steps are notorious for getting cracked or torn off — usually from a rock, stump, tree, or even just stepping on them the wrong way.
It uses a modern variable-speed inverter compressor (not the old fixed-speed rotary style), so cooling output and power draw automatically adjust to demand.
Why DR1?
- Engine-off operation capable
- Battery-friendly variable-speed operation
- Designed for high ambient temperatures (35°C+)
- Can be run while driving (many rooftop units are park-only)
Compressor & Operating System
Compressor type: Variable-speed inverter
Typical operating speeds:
- Low: ~1500 RPM (temperature holding / low load)
- Medium: ~3000 RPM (normal cooling)
- High: ~4500 RPM (rapid pull-down on hot starts)
As the cabin cools, the compressor automatically reduces speed and current draw. This is significantly more efficient than older rotary compressors that run flat-out continuously.
Electrical & Power Consumption
| System | Current Draw | Power |
|---|---|---|
| 12V | 16–75A | ~500–800W |
| 24V | 8–35A | ~200–800W |
Battery Protection
- Soft-start (reduces startup spike)
- Low-voltage cut-off (helps prevent battery drain)
