SHAVER

● Superior Environmental Performance

Adopts eco-friendly refrigerants: R410A for low-temperature stage, R134a and R515B for high-temperature stage. All refrigerants feature zero ODP, non-toxic and non-flammable with excellent environmental compatibility.

The GWP of R134a is 1430, while R515B is a new-generation eco-refrigerant with an ultra-low GWP of only 299, delivering far lower global warming potential than R134a.

● Ultra-Low Ambient Temperature Operation

Equipped with advanced two-stage cascade technology, the unit effectively reduces the system compression ratio under low ambient temperature conditions, and delivers powerful heating performance even at an extreme ambient temperature of -35°C.

● Ultra-High Hot Water Output Temperature

Fitted with top-tier brand high-temperature dedicated scroll compressors worldwide:

For R134a high-temperature compressors, the maximum evaporation temperature hits 40°C and maximum condensation temperature reaches 85°C, enabling the unit to provide stable hot water at 80°C all year round.

For R515B high-temperature compressors, the maximum evaporation temperature reaches 50°C and maximum condensation temperature hits 100°C, supporting constant 95°C hot water supply throughout the year.

● Wide Range of Application Scenarios

Cascade heat pumps operate stably under ambient temperatures from -35°C to 45°C. When the high-temperature stage uses R134a, the hot water outlet temperature ranges from 40°C to 80°C; when R515B is adopted for the high-temperature stage, the outlet temperature ranges from 40°C to 95°C. The units fully meet hot water supply demands in frigid cold regions.
