MILAN, Italy, 12 March 2024: GMCC & Welling, an Integrated Core Components Solution Provider for heat pumps, announced that it showcased in Mostra Convegno Expocomfort (MCE) 2024 in Milan, Italy. Making the announcement through a Press release, GMCC & Welling said, it demonstrated to European and global consumers core components and solutions such as rotary compressors; scroll compressors; fans for heat pumps; motors for heat pumps and circulating pumps for a wide array of applications covering heat pump space heating, heat pump water heaters, heat pump dryers and swimming pool heat pumps. 

Spokesperson, GMCC & Welling Europe, said: The company has become the industry leader in R290 eco-friendly refrigerant technology, thanks to years of commitment and efforts to meet European consumers’ demand for energy-efficient, eco-friendly, high-performance products. For the next phase, GMCC & Welling will develop and build heat pump products that are more efficient, green and environmentally friendly with whole machine manufacturers. 

GMCC said it unveiled R290 refrigerant rotary and scrolls compressors specifically designed for heat pumps, covering fixed-speed and inverter products. The GMCC also said that the R290 heat pump rotary compressor for space heating offers a product portfolio from 2kW to 25kW, with specialised compressors of smaller size yet greater efficiency based on characteristics of R290 refrigerant and requirements of heat pump space heating applications. Furthermore, GMCC said the heat pump scroll compressor for space heating increases energy efficiency by five per cent, thanks to the asymmetrical spiral line and multi-stage pressure relief static plate technology, perfect for large-capacity and high-end heat pump systems. 

GMCC said the heat pump rotary compressor for the water heater has a wide operating envelope with 55 degrees C outlet water temperature even in cold winter while maintaining stable operation at different seasonal temperatures. In addition, GMCC also said that it had developed highly efficient and reliable heat pump compressors for swimming pools and heat pump rotary compressors for dryers, providing a comprehensive product portfolio for a wide range of heat pump applications in Europe. 

GMCC said Welling’s fans and motors for heat pumps also excel in energy efficiency. Welling’s fan for heat pump space heating adopts intelligent EC control technology to receive intelligent feedback on the fan operation status while enhancing overall efficiency with large torque and a highly efficient outer rotor. GMCC added that Welling’s fan for the heat pump water heater provides axial flow, forward centrifugal and backward centrifugal solutions. Moreover, GMCC said the outstanding blade fluid design of  Welling’s fan with an efficient, silent outer rotor motor offers optimal energy efficiency and silent operation. In terms of motors for heat pumps, GMCC said, Welling’s motor for heat pump space heating increases the magnetic flux utilisation by 7.7% and effective space and material utilisation by five per cent while reducing shaft voltage amplitude by 60%. GMCC said, it is therefore characterised by high efficiency, compact size and high reliability. The motor for a heat pump water heater includes different options such as resin encapsulation brushless DC motors and iron-clad asynchronous AC motors to meet customers’ various power requirements, GMCC further said. 

In R&D and application of circulating water pumps for heat pump space heating, GMCC said Welling adopts a condensate protection design and anti-jamming, simple-maintenance design to achieve high reliability while further optimising efficiency and volume. In addition, GMCC said that in the electronic expansion valve product category, it unveiled the M series with high reliability and flow accuracy, the W series with extremely low noise, and the L series with ultimate miniaturisation. These products are widely applicable to various complex application scenarios.
