Behind the Scenes: How We Build Reliable R290 Monoblock Heat Pumps

What makes a stable and reliable R290 heat pump?

Here is a quick look at our production & testing workflow:

1. Full-process R290 charging line
Safe, precise and fully enclosed charging system.

2. 100% performance testing
Each unit goes through heating/cooling performance tests following EN14511.

3. Noise & vibration control
We optimize the compressor layout, PCB design and airflow structure to achieve industry-leading quiet operation.

4. Low-temperature climate simulation
We run tests at –20°C to ensure stable performance for European winter conditions.

A stable R290 heat pump comes from strict engineering, not marketing.
