Our flagships models configured with tropical-grade anti-corrosive coatings and variable-frequency compressors optimized for Mozambique's sub-tropical and oceanic climates.
As Mozambique transitions into a major natural gas, mineral processing, and regional economic hub, commercial businesses face an urgent challenge: high operational overheads driven by unstable energy grids and inefficient thermal machinery. Traditional boiler systems based on diesel or direct electric resistance heating impose severe operational costs on food processors, mining infrastructure, and luxury tourist lodges alike.
From Maputo's booming business towers to the industrial zones in Beira and the deep-water ports of Nacala, the demand for sustainable energy is surging. Our high-efficiency EVI (Enhanced Vapor Injection) DC Inverter Heat Pumps present an ideal solution, capturing ambient heat from Mozambique's rich sub-tropical climate. By reducing electricity consumption for hot water and commercial heating by up to 75% compared to conventional thermal systems, we help businesses unlock long-term profitability.
Unlocking thermodynamic stability and high-output water heating across extreme seasonal transitions and highly corrosive coastal environments.
Standard heat pumps experience sharp drops in COP (Coefficient of Performance) during periods of high ambient humidity or temperature spikes. Our EVI technology employs a secondary electronic expansion valve and flash tank system. By injecting vapor mid-stage into the scroll or rotary compressor, it expands the refrigeration system envelope, providing high discharge temperatures while keeping the compressor motor operating safely below thermal threshold limits.
Driven by advanced dual-rotary Panasonic or Mitsubishi DC compressors and brushless DC fans, the system dynamically scales performance from 30% to 100% frequency to perfectly match instantaneous thermal load demands. This eliminates the massive power surges typical of traditional fixed-speed (On/Off) compressors, a crucial factor in shielding off-grid solar microgrids from failure.
Mozambique's extensive 2,470 km shoreline exposes heat exchangers to high-salinity air, promoting rapid oxidation. Our heat pumps feature hydrophilic gold fin coatings on aluminum evaporators, and heavy-duty C5-M rated epoxy pre-treated structural frames. This ensures long-term resistance to salt mist spray and prevents rapid performance decay.
Custom configurations engineered to maximize production efficiency, lower environmental footprints, and guarantee operational continuity.
Luxury coastal resorts in Bazaruto and Vilankulos require huge quantities of hot water for guest sanitary demands and private swimming pool temperature regulation. Our integrated air-source EVI heat pumps run silently in the background, utilizing R290 or R32 eco-friendly refrigerants. By pairing with solar PV arrays, resorts can achieve near net-zero carbon operations.
In remote regions like Tete Province, mining camps house thousands of workers requiring reliable hot water for sanitization, dining halls, and laundry services. By integrating modular, commercial-scale EVI heat pumps, operators can phase out expensive, diesel-burning hot water boilers and minimize transport logistics for remote fuel deliveries.
Mozambique's agriculture and aquaculture operations rely on stable temperatures for seed sprouting, fish farming (shrimp/tilapia hatcheries), and drying applications. Our systems provide precise water temperature regulation within a tolerance of ±0.5°C, ensuring optimal biological conditions and high crop yields.
Engineered to work reliably even under low-temperature drops or extreme sub-tropical summer conditions.

Our design engineering process ensures compliance with local grids and long-term hardware survival in challenging regional networks.
Voltage instability is common in remote industrial and mining areas of Mozambique. To prevent electrical failures, our EVI heat pumps feature an integrated low-voltage start-up system, operating reliably down to 180V for single-phase systems and 320V for three-phase installations. Built-in phase sequence protection and phase-loss safeguards prevent motor reverse-running or burnouts due to local utility issues.
Our units support integration with solar PV systems via smart dry-contact relays or Modbus RS485 communication protocols. The EVI DC Inverter is configured to ramp down its speed based on available solar battery levels or grid supply conditions, providing an ideal thermal storage or water heating option for off-grid operations.

Expert responses to common technical and operational inquiries regarding heat pump deployment in Mozambique.
Although EVI (Enhanced Vapor Injection) is primarily designed to improve low-temperature performance in cold climates, it offers significant advantages in hot environments. When ambient temperatures exceed 40°C, the refrigerant density drops, which can cause standard compressors to overheat. EVI injects cooler refrigerant vapor into the compression cycle, lowering the discharge temperature of the compressor. This allows the system to operate safely and maintain high COP efficiency without triggering thermal shutdowns.
Salt-spray corrosion is a major cause of early heat pump failure along coastal Mozambique (e.g., Maputo and Beira). High salt concentration speeds up the oxidation of aluminum fins on the evaporator, reducing heat transfer efficiency and leading to leaks. To prevent this, our systems are built with specialized copper tubes, hydrophilic gold-fin evaporators, and powder-coated cabinets that offer excellent resistance to marine environments.
Yes. Our DC Inverter systems feature soft-start capabilities, which prevent current spikes when starting up. This makes them ideal for hybrid solar setups. By adjusting output based on solar generation, they help reduce battery cycling and lower overall energy costs.
Our standard production time is 30 to 45 days after order confirmation. Shipping from Shenzhen or Nansha port to Maputo or Beira port usually takes between 25 and 35 days, depending on shipping line schedules and routing.
