With a focus on sustainability, performance, and long-term reliability, the EGB range is fast becoming a preferred solution among leading mechanical contractors, engineers, and developers throughout South Africa.
The Greenbro EGB Range of Heat Pumps, are designed specifically for high-demand hot water systems across residential, commercial, and industrial developments.
Powered by EVI (Enhanced Vapor Injection) Technology, the EGB Range delivers outstanding energy efficiency and performance, even in low ambient temperature environments.
Superior Cold-Climate Performance: Traditional heat pumps struggle in very low temperatures, while EVI heat pumps operate efficiently in low ambient conditions. This makes them ideal for regions with harsh winters.
Higher Output Temperatures: EVI heat pumps can produce hot water up to 65°C, compared to 55-60°C for standard models. This makes them suitable for applications requiring higher water temperatures.
Enhanced Efficiency (COP): The EVI cycle injects additional vapor into the compression process, resulting in a higher Coefficient of Performance (COP). That means more heating output per unit of energy consumed, translating to lower running costs.
Expanded Operating Range: With EVI technology, these units can maintain performance across a broader range of outdoor temperatures, ensuring stable hot water delivery.
Reduced Compressor Stress: By lowering discharge temperatures and improving oil return, EVI compressors run smoother, resulting in less mechanical wear and longer system lifespan compared to traditional compressors.
Eco-Friendly Refrigerant Options: Many EVI heat pumps use low-GWP refrigerants like R407C, offering a more environmentally responsible solution with reduced carbon footprint.
Ideal for Demanding Applications: Due to their high efficiency and heating capacity, EVI heat pumps are well-suited for large residential developments, commercial buildings, hotels, and hospitals, where consistent high-temperature heating is required.
An EVI (Enhanced Vapor Injection) compressor is a type of compressor used in heat pump systems to improve efficiency, especially in low-temperature conditions. It utilizes an intermediate cooling and vapor injection process that enhances performance compared to standard compressors.
It uses a special economizer or sub cooling circuit to inject additional refrigerant vapor into the compressor at an intermediate pressure.
This process reduces the discharge temperature, increases cooling/heating capacity, and improves efficiency.
