In the latest Danfoss conversation, host spoke with and about protecting in challenging and applications. The focus was on extreme low-temperature operations, , and ensuring without . This is part three of a seven-part series.

Kitchen explained the challenges: “When you run low-temperature systems, or push heat pumps to the limits, you increase the compression ratio. That’s where protecting the compressor becomes critical.” Saar agreed, highlighting the role of discharge thermostats: “Discharge thermostats monitor the compressor’s discharge line. If temperatures exceed safe limits, the thermostat can prevent catastrophic failure, especially when refrigerant charge is lost.”
