Problem
- Fungus formation in garment in finished product during storage
- 98% RH with 30C ambient temperature
We partnered with the client to design and implement solution with Danfoss SZ110 scroll compressor and allied controls (Expansion valve, Filter Drier, Sight Glass, Solenoid Valve, Pressure controls, Temperature sensors) that addressed these challenges while incorporating key unique selling propositions (USPs). Danfoss and FX technical team played important role to run the tests for worst operating conditions and got it qualified.
