Delta’s EC fans for the safety and efficiency of heat pumps with next-generation refrigerants<\/strong><\/h4>\n

The adoption of next-generation heat pumps<\/strong> that use low global warming potential (GWP) refrigerants – such as R290 (Propane)<\/strong> – has set a new standard for the development of sustainable, environmentally friendly heating systems. Delta’s EC fans<\/strong>, from Delta<\/strong><\/a>, are a cornerstone of these new heat pumps, which aim to deliver truly \u201cgreen\u201d technology, in line with the EU’s sustainability goals.<\/p>\n

\"EC<\/p>\n

Refrigerants play a key role in the transition toward reducing greenhouse gas emissions<\/strong>, replacing hydrofluorocarbons (HFCs) with a high \u201cglobal warming potential\u201d with low-GWP natural alternatives such as Propane and CO2, in line with the EU’s F-gas regulation<\/strong> and the Paris Agreement.<\/p>\n

Although heat pumps using natural refrigerants<\/strong> have reached a mature stage and are considered a safe technology, they present unique challenges due to their high flammability<\/strong>. Manufacturers of heat pumps using flammable refrigerants must comply with strict regulations regarding system design, safety, installation and operation.<\/p>\n

EC fans for gas extraction<\/h5>\n

Delta’s fans are safe and specifically designed for primary and secondary ventilation applications within heat pump modules. Delta’s axial EC fans, for residential and industrial applications,<\/strong> range in size from 120mm to 800mm<\/strong> and are designed to meet the strict requirements of these applications. Most Delta EC fans are compliant with the A2L and A3 refrigerant safety standards<\/strong>, have very low energy consumption, a highly energy-efficient motor >90%<\/strong> and a cutting-edge blade design<\/strong> that ensures maximum airflow and minimal noise levels<\/strong>, while excelling in both performance and reliability.<\/p>\n

In industrial applications, the heat pump often includes a second level of ventilation (secondary fans) for gas extraction in the event of leaks. Delta offers a complete range of ATEX-certified EC fans specifically designed for \u201cgas extraction.\u201d<\/strong> In fact, for systems with a high quantity of flammable refrigerant, the F-gas regulation requires frequent leak checks; a leak detection system is therefore often included. The secondary fan is activated when this system detects a refrigerant level above the threshold. Due to direct contact with the refrigerant, this fan must necessarily be<\/strong> ATEX certified, for safe operation in potentially hazardous environments.<\/p>\n
