Welcome to the Heat Pump Manufacturing Line at Sidite Tounite!


How do we ensure every air-to-air heat pump meets the highest quality standards? It starts with a helium leak test, an extremely precise method to detect any leaks. Every unit undergoes this test to guarantee reliability.

Next, we perform a vacuum pumping process, followed by automatic refrigerant charging, ensuring each unit operates at peak performance.

Once the refrigerant is charged, the heat pump goes through a comprehensive running test to verify flawless functionality before it leaves our factory – no compromises!

This is our dedicated production and testing area, where precision and quality are our top priorities. After a second halogen leak test, we finish with assembly and packaging, getting the heat pumps ready for delivery.

Quality. Reliability. Efficiency. That’s the Sidite Tounite promise.
