DR1 Rooftop Electric Air Conditioner

Premium high-output cooling for trucks, campers, boats & heavy machinery

When you’re chasing serious cooling performance, the DR Series sits right at the top. With its oversized condenser, twin 300 mm high-flow fans, stainless fittings, copper/aluminium core design and a smart variable-speed inverter compressor, this unit is built to cool bunk cabins, long-haul trucks, large campers, heavy machinery, boats and off-grid setups with ease.

This is the flagship rooftop unit — big power, big reliability, built for harsh Aussie heat.

Variable-Speed Inverter Compressor (Corrected Information)

The DR unit does not run at a fixed RPM. It uses a true variable-speed inverter compressor, meaning it automatically adjusts its speed depending on cooling demand.

Typical operating bands are:

• Low: approx. 1500 RPM (holding temperature / low load)

• Medium: approx. 3000 RPM (regular cooling)

• High: approx. 4500 RPM (rapid cool-down on hot starts)

This variable-speed system allows:

• Faster initial cooling

• Lower current draw once the area is cool

• Much quieter operation

• Less strain on batteries

• Longer compressor life

Power Consumption

• 12V version: 16–75A (500–800W)

• 24V version: 8–35A (200–800W)

As the temperature stabilises, the compressor automatically slows down, dramatically reducing power draw.

Battery Protection

• Soft-start system (no large current spike)

• Low-voltage cut-off (prevents flattening your batteries)

Smart tech designed for engine-off use and off-grid systems.

Refrigerant

The system uses R134a, which is the standard automotive refrigerant used by most cars, 4WDs, trucks and machinery in Australia.
Any licensed automotive A/C technician can gas it easily.
