Norsup Inverter Heat Pump Steel 50 mm 9A 400VAC Black Horizontal Type SG Silent-Pro 28T

Precise heating all season long

The Norsup SG Silent-Pro 28T heat pump uses full inverter technology that dynamically adjusts heating output to current weather conditions and heat demand. This allows the unit to operate extremely efficiently – COP reaches up to 16 at A27/W27, resulting in low operating costs and a fast return on investment. This model is designed to operate in temperatures down to -15°C, making it a year-round solution for both heating and cooling pool water.

The dual air outlet design and fully variable fan speed achieve noise levels as low as 19 dB(A) – quieter than a whisper. Combined with a steel housing and titanium heat exchanger resistant to salt and chlorine, the pump guarantees long-term reliability even in harsh conditions. A winter cover is also included to protect the unit during the off-season.

Built-in Wi-Fi and 4G modules enable remote control and monitoring of operating parameters from a smartphone. A full-color touchscreen provides intuitive operation, and Power, Smart, and Silent modes allow energy consumption to be optimized based on needs. SmartGrid technology additionally enables integration with home photovoltaic systems – the pump automatically adjusts power consumption to available renewable energy.

Key benefits

• Energy class A – maximum efficiency and low electricity bills.
• Quiet operation from 19 dB(A) – ideal for gardens and relaxation areas.
