Their exhibit will highlight a comprehensive range of products designed for various applications, including heat pump space heating, water heating, and washroom appliances. All of these units utilise the environmentally friendly R290 refrigerant. Key offerings include fixed-speed and inverter compressors, BLDC motors, EC fans, and circulating pumps.
As heat pump technology is crucial in reducing global dependence on fossil fuels, GMCC & Welling is set to contribute further to sustainable development worldwide by leveraging their innovations in core heat pump components.
GMCC & Welling have developed a comprehensive offering of core components to meet consumers’ growing demand for high-efficiency, reliable, and quiet heat pump heating solutions. These include the R290 Inverter Scroll Compressor, R290 Inverter Twin-Cylinder Rotary Compressor, BLDC Motor, and circulating water pumps. These products meet the rigorous requirements of heat pump systems and provide an integrated “compressor + motor” solution for more competence.
Take the 135CC R290 Inverter Scroll Compressor from GMCC, for example. It features a high-efficiency pump design, optimised motor structure, high reliability, low noise, low vibration, and an EVI (Enhanced Vapor Injection) function to ensure superior efficiency, lower noise levels, and enhanced reliability.
GMCC’s R290 Inverter Rotary Compressors for Heat Pump heating applications are also a star product that highlights improved Coefficient of Performance (COP), reduced noise levels, and higher operational safety. GMCC has continuously invested in the product’s R&D and introduced IP54/IP67 terminal covers for enhanced operational safety. These innovations further solidify GMCC’s R290 heat pump heating sector leadership.
For heat pump water heating applications, GMCC & Welling offer a range of solutions incorporating GMCC Fixed-Speed and Inverter Rotary Compressors and Welling BLDC Fans and EC Fans, providing customers with multiple options that fully cover the diverse application needs of “compressor + motor” integration.
GMCC’s R290 fixed-speed single-cylinder rotary compressor has been specifically optimised for R290 refrigerant, delivering exceptional heating efficiency. It supports a maximum water temperature of 65°C and can maintain the temperature at 55°C even in winter. Designed for a service life of 60,000 hours, it meets European market demands while enhancing reliability. Its wide operating range also ensures stable performance under high-load summer weather and high-pressure ratio winter weather. Moreover, the product also features a low-noise valve system developed from a fluid-structure interaction simulation, ensuring exceptionally low noise levels.
In summary, GMCC & Welling provide customers with a wide array of core components and solutions for various heat pump applications, including heating, water heating, and dryers. Their offerings include different types of compressors, BLDC and EC fans, asrculating water pumps and electronic expansion valves, enabling a comprehensive system solution for global customers.
Notably, Welling’s “BLDC motor + Axial Fan” combination—introduced for heat pump heating and water heating applications—delivers low power consumption, low noise, and cost-efficient large-scale production. It is also fully compatible with R290 refrigerant and meets G6.3 safety standards, ensuring environmental sustainability, operational safety, and high efficiency.
As a key advocate in the global transition to environmentally friendly refrigerants, GMCC & Welling showcase their extensive range of R290-compatible compressors and motors, reinforcing their commitment to green development.
GMCC began investing in R290 refrigerant technology and product development as early as 2004, and today, the company boasts a comprehensive R290 portfolio across multiple categories, including air conditioners, portable air conditioners, refrigerators, freezers, light commercial refrigeration, and heat pump applications for heating, dryers, and water heaters. Innovating to make the size more compact and the energy consumption lower, GMCC has enhanced the safety, reliability, and energy efficiency of R290 High-Efficiency Compressors, earning widespread recognition from both the market and customers.
