Ramsond RDZ‑28HP‑230V0 — 28,000 BTU Free‑Match Outdoor Condenser

High‑Efficiency Dual‑Rotary Compressor

The SANYO dual‑rotary compressor is the heartbeat of the RDZ system. Its dual‑rotor design minimizes vibration, enhances torque stability, and ensures reliable heating performance even in extreme low‑ambient conditions.

• Model: C‑6RZ180H1AAF
• Ultra‑low vibration
• Optimized for R454B
• High‑efficiency modulation
• Whisper‑quiet operation

The integrated crankcase heater prevents refrigerant migration during freezing temperatures, ensuring safe compressor startup and maintaining proper lubrication.

Frost buildup reduces heating efficiency. The RDZ‑18HP‑230V0 uses a sensor‑driven defrost algorithm that activates only when needed, improving energy efficiency and maintaining consistent heating output.

Once activated, the ODU axial fan reverses direction, generating a powerful airflow that blows out accumulated dust, particles, and debris from the outdoor unit’s fins.

This automatic self‑cleaning cycle helps maintain peak heat‑exchange efficiency, reduces maintenance needs, and ensures long‑term system reliability.

• Clears dust and buildup from condenser fins
• Improves airflow and cooling performance
• Reduces service frequency
• Enhances long‑term durability

Ramsond stands behind every RDZ system with industry‑leading protection designed to keep homeowners comfortable and technicians confident. When reliability matters, Ramsond delivers peace of mind without compromise.

And unlike many brands, Ramsond keeps parts in stock. If a unit ever goes down, replacement components are ready — no long waits, no backorders, no downtime. Your comfort stays protected.
