The SPR units are ideal for swimming pools that not only require dehumidification but must also renew the indoor air without dispersing heat outdoors. Up to 80% yield is guaranteed by the high-efficiency recovery system. The SPR units represent the state-of-the-art in terms of efficiency, reliability and emitted sound power. The SPR range only uses electronic radial fans with high-energy efficiency incorporated inverter. HiDew has developed a sophisticated adjustment software to adjust the SPR dehumidifiers air flow rate. This software sets, measures and controls the air flow rate, eliminating any chance of incorrectly calculating the ducts’ pressure drops, thereby making dehumidifier installation and system commissioning extremely easy and quick and reducing installation times and costs.
