Welcome to Sidite Tounite’s Heat Pump Production Line!
How do we make sure every one of our air-to-air heat pumps is top quality? First, we do a helium leak test – a highly accurate method to check for any leaks. Every single unit gets this test to guarantee reliability. Next up, we move to the vacuum pumping process, followed by automatic refrigerant charging to ensure optimal performance. Then, each heat pump undergoes a running test to verify it works perfectly before leaving the factory – no shortcuts here! This is our complete production and testing area where precision and quality are our top priorities. After the second halogen leak test, we finish with assembly and packaging to prepare these heat pumps for you!
