Against the backdrop of tightening global refrigerant regulations, many heat pump OEMs face a dilemma when selecting compressors. High-GWP refrigerants are under growing restrictions, while alternative solutions either bring high modification cost for complete units or suffer obvious performance degradation under high ambient temperatures. The GMCC EDTM310D85EMT, an R290 DC inverter twin rotary compressor, is developed to address this pain point. It is mainly applied in light commercial heat pumps and residential low-temperature heat pumps for export projects, suitable for extreme conditions with hot summers and cold winters in the Middle East and Southern Europe.
EDTM310D85EMT Core Specifications
Two concerns often trouble OEM engineers working with R290 compressors: maximum safe refrigerant charge and capacity drop under high ambient temperatures. The EDTM310D85EMT adopts targeted design optimizations. Internally, it uses GMCC proprietary propane-resistant materials. The motor insulation is matched to the R290 lubrication system. Meanwhile, optimized exhaust silencing structure reduces vibration under continuous full-load operation and lowers the risk of pipeline fatigue of heat pump units.
Compared with R410A models of equivalent cooling capacity, the biggest advantage of EDTM310D85EMT is not merely improved energy efficiency, but its long-term compliance value. The EU F-Gas Regulation continues to restrict the placement of high-GWP HFC refrigerants on the market. As a natural refrigerant, R290 is not subject to HFC quota controls. By adopting this compressor, OEM manufacturers do not need to reserve extra budget for future HFC quota price hikes, and their products enjoy a longer compliance cycle for exports to EU, Southeast Asian and Middle Eastern markets.
In terms of operating conditions, this model can run stably under 46℃ T3 high ambient. 43℃ represents typical daily high temperature in the Middle East. When equipped with a properly sized accumulator and control logic, it can start heating reliably at an ambient temperature of -20℃, making it suitable for regions with large day-night temperature differences. For heat pump OEMs, the EDTM310D85EMT comes with mature control electronics and complete GMCC drive solutions. OEMs do not need to develop electronic controls from scratch, shortening new product launch cycles.
If you are developing export heat pumps and looking to replace legacy R410A models while meeting low-carbon compliance requirements, the GMCC EDTM310D85EMT is an R290 inverter compressor balancing performance, regulatory compliance and supply chain stability.
