Seamless pure titanium tube offers superior corrosion resistance against chlorine, salt, and chemicals – long service life with minimal after‑sales maintenance.
Ultra‑Quiet Operation
DC inverter fan motor + sound‑absorbing cotton wrapping + twin‑rotor balance reduce noise by 8–10 dB(A) compared to scroll‑compressor units.
R32 Eco Refrigerant
Lower GWP (675) – compliant with F‑Gas phase‑down. Non‑toxic, stable, with excellent heat transfer performance.
Smart Connectivity
Modbus protocol (BACnet / BMS optional). IoT remote monitoring with OTA updates. PV direct connect via MPPT board cuts running costs by ~50%.
Module Parallel & Rotation
Up to 8 units parallel‑controlled by one controller. Rotation operation balances runtime across units and compressors, extending overall lifespan.
Multiple Protections
High/low pressure switches, anti‑freeze, overload, phase sequence protection, and real‑time auto‑alarm for safe, worry‑free operation.
Heating & Cooling
‑way valve enables both heating and cooling modes – year‑round pool comfort in any season.

1
How quiet is the Commercial Pool Heat Pump?
Noise levels range from 54 dB(A) to 80 dB(A) at 1 meter, depending on the model. The DC inverter twin‑rotor compressor and sound‑absorbing materials reduce noise by 8–10 dB(A) compared to traditional scroll‑compressor units.
2
Can it handle cold winter conditions?
Yes. EVI (Enhanced Vapor Injection) technology ensures stable heating performance down to –35°C ambient temperature, making it suitable for cold climates.
3
Is the heat exchanger corrosion‑resistant for saltwater pools?
Absolutely. The titanium heat exchanger uses seamless pure titanium tubing, offering superior resistance to chlorine, salt, and chemicals – ideal for both freshwater and saltwater pools.
4
Can I connect the unit to my building management system?
Yes. The unit supports Modbus protocol as standard, with optional BACnet and BMS integration for seamless building automation.
5
ow much can I save on energy costs?
With a COP of up to 6.1, the heat pump generates 6.1 kWh of heat per 1 kWh of electricity consumed – up to 6 times more energy‑efficient than traditional boiler systems. When paired with PV solar via direct MPPT connection, running costs can be reduced by approximately 50%.
6
Can multiple units work together?
Yes. Up to 8 units of the same model can be paralleled and controlled by a single wire controller. Rotation operation balances runtime across units to extend overall system life.
