Engineered to withstand tropical oceanic conditions, highly saline atmospheres, and optimized for extreme thermal efficiency.
Evaluating volcanic hydrology, high-cost electrical grids, and decentralized thermal engineering paradigms in Grande Comore, Anjouan, and Mohéli.
The Union of the Comoros, located off the southeastern coast of Africa, faces unique energy challenges and natural resource opportunities. With high volcanic activity, notably Mount Karthala on Grande Comore, the island holds highly promising geothermal profiles. Furthermore, its surrounding tropical marine environments are highly suitable for Ocean Thermal Energy Conversion (OTEC) and Seawater Source Heat Pump (SWHP) systems. Ground-source and seawater-source thermal loops represent a massive opportunity to decouple Comoros' industrial and commercial growth from imported diesel generators, which currently strain the local economy.
Traditional heating, ventilation, and air conditioning (HVAC) systems in Moroni and surrounding regional centers run on low-efficiency split-type air conditioners that put stress on unstable municipal grids. In comparison, Water Source Heat Pumps (WSHPs) harness the thermodynamic stability of shallow volcanic aquifers or deep ocean waters. A WSHP system utilizes water as the heat exchange medium, yielding Coefficients of Performance (COP) as high as 5.5—saving up to 65% in electricity consumption compared to standard combustion or electric resistance heaters.
Because the Comoros electricity grid relies heavily on thermal diesel generators, every kilowatt-hour of energy saved prevents a direct carbon emissions equivalent. Guangdong Retro Pumps has optimized its product lineup to assist commercial developers, high-end ecotourism villas, and agricultural process engineers across Anjouan and Mohéli. By implementing low-GWP refrigerants (R290 and R32) combined with high-capacity variable speed hermetic scroll compressors, our systems run efficiently even under unstable grid voltages.
How water-source and premium air-source thermodynamic loops serve key sectors of the local economy.
Moroni, Mohéli, and surrounding coral islets demand silent, low-visual-impact heating and cooling systems. By utilizing sea-source or ground-loop heat exchangers, resorts can heat infinity pools, supply domestic sanitizing water up to 75°C, and provide high-efficiency chilled water air conditioning without loud outdoor fans or heavy diesel consumption.
Comoros is globally renowned for its high-grade Bourbon vanilla and ylang-ylang essential oils. The curing process of vanilla pods requires precise, continuous thermal control. Our high-temperature water source heat pumps supply exact, stable hot water loops to specialized agricultural drying rooms, ensuring top-tier crop quality while minimizing energy inputs.
Artisanal and commercial fisheries in the Comoros require high-efficiency ice makers and freezing tunnels. Modern multi-stage thermodynamic loops allow heat rejected from the freezing process to be recycled to provide free hot water for plant sanitation, dramatically cutting down general operational expenditures (OpEx) for marine processors.
A Pioneer in Global Low-Carbon Thermal Technology Engineering
Guangdong Retro Pumps Co., Ltd. is a highly specialized technological enterprise focusing on the R&D, structural design, manufacturing, and international supply of premium heat pump systems. Established in 2022 and situated in the global manufacturing capital of Foshan, Guangdong Province, China, Retro Pumps operates state-of-the-art facilities designed for maximum production efficiency and high quality assurance. Our infrastructure includes highly sophisticated water-loop system laboratories, dynamic environmental simulation testing chambers capable of replicating extreme ambient conditions, pilot run workshops, and automated electrical assembly lines.
Our leadership and engineering core consist of experienced industry veterans from Fortune 500 HVAC corporations. This deep expertise allows Retro Pumps to pioneer custom thermal solutions including residential, commercial, and heavy-duty industrial thermodynamic architectures.
Ensuring operational durability, global regulatory compliance, and seamless installation logistics in isolated grids.
For remote areas such as the Comoros archipelago, finding on-site thermodynamic service engineers can be challenging. Retro Pumps resolves this through integrated smart cloud monitoring. Our systems report real-time operational metrics—such as compressor temperatures, loop pressures, flow rates, and COP values—to our centralized engineering dashboard. This allows for proactive technical support, predictive maintenance scheduling, and remote system calibration.
With global mandates phasing out hydrofluorocarbons (HFCs) due to their high Global Warming Potential (GWP), our focus on R290 (propane)—a highly efficient natural refrigerant with a GWP of only 3—is a key advantage for our clients. Choosing R290 helps buyers future-proof their installations against regulatory phase-outs while improving thermodynamic efficiency by up to 10% compared to legacy refrigerants.

Water Source Heat Pumps utilize water (groundwater, lake water, or seawater) as the heat exchange medium. Because water has a much higher specific heat capacity and more stable seasonal temperatures than air, a WSHP achieves higher thermodynamic efficiency (COP 5.0+) compared to an ASHP (COP 3.2–4.2) under high ambient island temperatures. WSHPs also lack exterior fans, making them completely silent and immune to salt-spray wear on external fins.
Yes. Our heat pumps feature variable-frequency DC Inverter technology, which avoids the high current surges typical of traditional fixed-speed on/off compressors. They start up smoothly, making them ideal for integration with hybrid off-grid or grid-tied solar photovoltaic (PV) setups and battery banks, which are increasingly common across Grande Comore and Mohéli.
For open-loop seawater applications, we use high-grade Titanium or Cupronickel (BFe10-1-1) heat exchangers that are highly resistant to chloride ion corrosion. In addition, our structural metal chassis undergo a high-durability electrophoresis coating process and are sealed with polyurethane topcoats to achieve a marine-grade C5 corrosion resistance classification.
Our heat pumps are certified by international testing agencies and hold CE, CB, TUV, Keymark, and ErP A+++ Energy Labels. These rigorous certifications ensure our products comply with demanding European safety and environmental standards, simplifying building permits and project approval processes in the Comoros.
Designed for commercial hotels, industrial operations, volcanic highland climates, and marine leisure complexes.
