OA-TCS Series
Principle The OA-TCS series unit is a water-source heat pump-based chiller that utilizes rivers, lakes, or seawater as cooling and heating sources. During summer cooling, the unit supplies 7°C chilled water for indoor cooling. During winter heating, it provides 45°C hot water for indoor heating.

Features
- Modular design: Allows parallel connection of water systems for flexible configuration, meeting large cooling/heating demands, improving regulation performance, and reducing starting current.
- Removable coaxial tube-in-tube heat exchanger on the river/lake/seawater side for easy cleaning and maintenance.
- Capable of heating with low water source temperatures as low as 3°C, maintaining over 70% of rated heating capacity.
- Fully enclosed imported brand compressor with low noise levels.
- Digital control with multiple protection functions.
- Designed for corrosion, vibration, and sway resistance.
- Modular frame structure supports horizontal or vertical parallel arrangement to suit different spatial requirements.
Protection Functions
- Water flow protection: Protection against lack of water or flow interruption in both seawater and circulating water systems.
- Refrigerant pressure protection: High-pressure and low-pressure protection.
- Compressor protection: Overload and overheating protection.
- Water temperature protection:
- Low seawater temperature protection; inlet/outlet water temperature differential protection.
- Circulating water high/low temperature protection; inlet/outlet water temperature differential protection.
- Optional: Zinc anode anti-corrosion protection.
