The Dometic FreshJet 5 13,500 BTU rooftop air conditioner is a low-profile solution designed as a direct replacement for Penguin II units, offering modern performance without changing the fit or other components. Featuring built-in hard start, quieter operation, and a reinforced steel base, this unit delivers reliable comfort and long-term durability. Powered by R32 refrigerant and a simplified mechanical system, the FreshJet 5 provides efficient, dependable cooling while on the road.
Direct Penguin II Replacement
The FreshJet 5 is designed to directly replace Dometic Penguin II rooftop air conditioners while maintaining the same 10.5" low-profile installed height and standard 14" x 14" roof opening. Backwards compatibility means no roof modifications are required when upgrading from Penguin II models.
Efficient Cooling with R32 Refrigerant
This unit uses R32 refrigerant, which delivers higher performance with less refrigerant volume. The result is improved cooling efficiency, faster cooling, and reduced environmental impact compared to older refrigerants.
Reliable Startup Power
An integrated hard-start system helps ensure dependable compressor startup on generators and limited electrical service, ideal for boondocking or campground hookups where power may fluctuate.
Built for Long-Term Durability
- Reinforced steel base resists vibration and road shock
- Coated evaporator coils improve heat transfer and corrosion resistance
- High-performance motors and fans support quieter, consistent airflow
- Fixed-speed compressor provides dependable mechanical operation
These features work together to extend system life while maintaining strong cooling performance over time.
