Yacht combined heater-air conditioner OA-ZY Series

monoblocreversible

The OA-ZY Series is an integrated yacht air conditioning unit that combines the compressor, condenser, expansion device and evaporator into a single water-source heat pump system suitable for marine installations. It uses river, lake or seawater as the heat sink/source. In cooling mode the condenser is water-cooled and the fan supplies cold air; in heating mode the unit extracts heat from the water and the fan delivers warm air.

Features:

• Compact structure and reduced footprint for installation aboard yachts.
• Low-noise EC fans optimized for marine environments.
• Low starting current; soft-start module available for specific electrical constraints.
• Compatible with eco-friendly refrigerants (R410A / R134a) with strong cooling and heating capacity.
• Digital control with comprehensive protection functions for safe operation at sea.
• Corrosion-resistant, vibration-damped and anti-rolling design for onboard reliability.
