Direct from China's leading R&D laboratories, our high-performance DC inverter heat pumps utilize eco-friendly refrigerants and advanced thermodynamic technology to optimize seasonal energy efficiency.
Across the European Union, North America, and high-growth Asian economies, commercial and industrial thermal energy demands are shifting rapidly toward low-GWP, high-efficiency DC inverter technology.
Strict European Union guidelines under the F-Gas mandate are accelerating the phase-out of traditional high-GWP HFCs like R410A. Global procurement officers are prioritizing natural refrigerant thermodynamic solutions such as Propane (R290) and Carbon Dioxide (R744/CO2) to future-proof investments.
Municipal heating systems and massive residential complexes require seamless automation. Modern inverter solutions must offer SG Ready (Smart Grid) interfaces, Modbus RTU, and Wi-Fi/Cloud connectivity to automatically modulate thermal output based on dynamic utility pricing.
For operations in Nordic regions, northern China, and North America, traditional heat pumps suffer steep performance drop-offs. Procurement requirements now dictate the use of Enhanced Vapor Injection (EVI) compressors, which maintain high COP levels down to ambient conditions of -30°C.

Evaluating thermodynamic potentials: How modern air-to-water systems optimize the transition from synthetic chemical refrigerants to natural, high-performance compounds.
| Refrigerant Type | GWP (Global Warming Potential) | Max Water Outlet Temp | Optimum Applications | Compliance / Environmental Impact |
|---|---|---|---|---|
| R290 (Propane) | 3 | 75°C | Residential space heating, high-efficiency radiators | Excellent safety standards, zero ozone depletion potential, highly recommended for EU markets. |
| R744 (Carbon Dioxide CO2) | 1 | 90°C | Commercial hot water systems, ultra-low sub-zero operations | Natural refrigerant, operates on a transcritical thermodynamic loop, zero F-Gas constraints. |
| R32 (Difluoromethane) | 675 | 60°C | Split systems, cost-effective residential units | Medium GWP, transitioning refrigerant with excellent volumetric capacity and lower charge limit. |
| R515B / R134a | <299 / 1430 | 85°C | Industrial drying, heat recovery generators | Targeted industrial applications with strict containment procedures. |
PeakWay’s engineering laboratories are advancing the integration of multi-stage scroll compressors and inverter drive boards. By combining EVI (Enhanced Vapor Injection) circuits with custom economizers, our systems increase heat capacity by up to 30% under deep sub-zero conditions. Additionally, variable frequency drives dynamically control fans and water pumps, maintaining a high Seasonal Coefficient of Performance (SCOP) even under partial load profiles.
Modern commercial buildings and industrial production lines demand integrated systems that go beyond standard Monobloc configurations.
Combining air source heat pumps with flat-plate solar collectors creates a highly resilient system. The solar thermal loop provides base temperature pre-heating, reducing energy consumption during peak periods and maximizing COP during cold winter months.
In manufacturing plants and large commercial kitchens, excess heat is often lost. Our waste heat recovery units capture thermal exhaust from refrigeration circuits and mechanical processes, returning it to domestic hot water loops to reduce operating costs.
For agricultural processing, timber, and manufacturing, wood-drying or fruit-dehydration requires consistent, high-volume heat. Our specialized high-temperature drying equipment replaces traditional coal-fired boilers, lowering carbon footprints by up to 70%.
Ensuring global logistics and regulatory compliance for our distribution and EPC partners in Europe, Australia, and North America.
Transitioning to green energy systems requires strict adherence to international safety and performance standards. Zhejiang PeakWay Pump Co., Ltd. ensures that all exported inverter heat pumps hold complete international certifications. This compliance process includes third-party audits by organizations like TÜV SÜD and Keymark, confirming that our products meet ERP A+++ energy efficiency ratings, CE safety requirements, and SG Ready network profiles.
To support global distributors and engineering firms, PeakWay offers a direct-to-factory technical support system. We provide diagnostic protocols, digital control board configuration interfaces, complete English and German technical manuals, and targeted warranty replacement components. This support helps our OEM/ODM partners minimize installation times and build long-term trust in local markets.
Expert engineering answers to technical questions about system design, COP optimization, and refrigerant selection.
R290 is a natural refrigerant with a Global Warming Potential (GWP) of only 3. It is not subject to F-Gas quotas and phase-down regulations. Its excellent thermodynamic properties allow it to achieve water outlet temperatures of up to 75°C, making it ideal for replacing boilers in older radiator networks without requiring expensive structural changes.
EVI technology injects a portion of refrigerant vapor into the intermediate chamber of the compressor cycle. This process cools the compressor interior, increases mass flow rate, and improves heating output at extreme temperatures, allowing the heat pump to operate reliably down to ambient conditions of -30°C.
Imports must meet CE directive safety standards. For financial subsidies, units must be certified under the HP Keymark scheme, comply with EN14511/EN14825 testing guidelines, and carry an official ERP energy label (ideally A+++ at 35°C and A++ at 55°C flow temperatures).
A Monobloc heat pump contains the entire refrigerant loop within a single outdoor unit, meaning water pipes run directly from the outdoor unit to the building. A Split system separates the circuit: the condenser is located indoors, and refrigerant lines connect the indoor and outdoor units, eliminating the risk of outdoor pipe freezing during power failures.
Yes. Using SG Ready control inputs, our inverter heat pumps can monitor solar production and run at higher thermal rates when excess PV electricity is available. This stores thermal energy in buffer tanks and reduces consumption from the grid.
Our manufacturing facility utilizes a multi-step quality control protocol: 100% helium mass spectrometer leak testing, automated electrical safety testing, water loop performance testing in specialized psychrometric chambers, and post-assembly vibration testing to ensure reliable operation during shipping and installation.
Engineered for hotels, factories, and agricultural drying systems, these heavy-duty inverter heat pumps provide clean energy solutions for high-capacity applications.
