In Singapore’s competitive HVAC maintenance industry, where refrigerant costs are soaring and efficiency is paramount, incomplete recovery of low-pressure refrigerants like R123 can lead to significant financial losses and operational inefficiencies. For a leading local contractor with over a decade of experience servicing top-tier AC brands, this challenge became a priority—until the ChunMu CMR123-20 Low Pressure Refrigerant Recovery Machine delivered a cost-saving solution.

Many HVAC maintenance teams in Singapore rely on over-positive pressure recovery machines, which struggle to handle low-pressure refrigerants such as R123, R11, R245fa, and R1233ZD. This limitation became costly for the contractor, especially as they took on more maintenance work for units using R123— a high-value refrigerant whose price has risen sharply in recent years.

Using their previous recovery method, the team was left with 80–150kg of residual R123 after each service. With refrigerant costs reaching approximately S$20 per kg (equivalent to 110 yuan/kg), this translated to losses of S$1,600 to S$3,000 per job. Over time, these recurring losses eroded profit margins and created a need for a more efficient, thorough recovery solution.

After researching solutions, the contractor turned to ChunMu’s CMR123-20 Low Pressure Refrigerant Recovery Machine—specifically designed to address the challenges of low-pressure refrigerant recovery. Unlike standard machines, the CMR123-20 is engineered to achieve a deep vacuum recovery of -0.09Mpa, ensuring near-zero residual refrigerant and eliminating waste.

Beyond its core recovery capabilities, ChunMu customized the machine to fit the contractor’s on-site needs: a wind-cooled version, which eliminated the reliance on a water source—critical for field maintenance work where water access is often limited. This adaptability ensured the machine could perform reliably in Singapore’s diverse maintenance scenarios, from commercial buildings to industrial facilities.

The impact of the CMR123-20 was immediate. By recovering every drop of R123 refrigerant, the contractor eliminated the costly waste that had plagued their operations. Customer feedback highlighted a rapid return on investment: the machine paid for itself in less than three uses. For the long term, the CMR123-20 continues to generate extra value by reducing refrigerant costs and improving operational efficiency.

For Singaporean HVAC maintenance teams facing similar challenges with low-pressure refrigerants, the CMR123-20 proves that targeted, custom-engineered equipment can turn waste into savings—while ensuring compliance and reliability.
