The selection of a dehumidifier's compressor should be determined based on the usage scenario and requirements. Piston compressors are suitable for residential use, rotary compressors are suitable for commercial use, and scroll compressors are suitable for industrial use.
Piston Compressor
Piston compressors are suitable for small dehumidifiers, with a cooling capacity generally within 1.3 kW. Their advantages include a simple structure, lower cost, easy maintenance, low noise, and minimal vibration. However, they have lower energy efficiency ratios and relatively higher energy consumption. They are highly suitable for residential dehumidifiers, especially in small spaces requiring a quiet environment.
Rotary compressors
Rotary compressors have a cooling capacity ranging from 200W to 3HP (approximately 2200W), with a higher energy efficiency ratio than piston compressors and higher dehumidification efficiency. However, they produce relatively higher noise and vibration. They are suitable for commercial dehumidifiers, such as in offices or shopping malls where rapid dehumidification is required and noise levels are not a major concern.
Scroll compressor
Scroll compressors have a cooling capacity of over 3HP (approximately 2200W), high energy efficiency ratios, and relatively low noise levels. However, they are less common in the market and have higher costs. They are primarily used in large industrial dehumidifiers, such as workshops and warehouses, where large-scale dehumidification is required and there are high demands on energy efficiency ratios.
The SIAL-C80 achieves a technical breakthrough in stable operation at 0°C by incorporating an international brand scroll compressor.
This compressor features an optimally designed scroll structure, combined with an automatic defrosting system for hot air, enabling it to maintain a rated dehumidification capacity of 80L/day even under extreme low-temperature conditions of -7°C to 0°C (such as in winter basements or northern regions during the “return of the south wind” season).
Test data shows that in a low-temperature environment of 10°C and 85% humidity, the C80 can reduce the humidity of an 180㎡ space from 90% to 55% within 2 hours. In contrast, conventional models frequently shut down due to compressor overload protection, resulting in significantly lower dehumidification efficiency.
