Products Advantages

Discover the core advantages that make Tongyi commercial pool heat pumps stand out – from exceptional energy efficiency and precise temperature control to reliable year‑round performance

DC Inverter + EVI

Twin‑rotary DC inverter compressor consumes 30% less power than traditional scroll compressors. EVI technology boosts low‑temperature heating capacity, ensuring stable performance down to –35°C.

Titanium Heat Exchanger

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.

Frequently Asked Questions

Tell us about your project requirements and we will figure out a solution that will meet your budget and design expectations.

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.

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.

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.

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.

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%.

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.
