NEW PRODUCT FLASH: ASCENDANT From SEMCO

SEMCO has introduced its ASCENDANT™ Series, an active desiccant hybrid system that provides conventional cooling and dehumidification for commercial applications requiring 100% outdoor air, and low dew point temperatures and supply air humidity levels as low as 15 grains.dehumidification

Geared for facility management applications that include hospital operating rooms, archival and dry storage, hotels, and multi-family buildings, ASCENDANT operates without the need for exhaust heat recovery, and can perform as a partial or dedicated outdoor air system (DOAS), or as a true variable air volume (VAV) unit. The series comprises five standard models ranging up to 20,000 cfm.

SEMCO’s ASCENDANT series provides conventional cooling and dehumidification for commercial applications.

When compared to conventional mechanical DX or chiller systems, ASCENDANT provides up to three times more dehumidification, achieves dew point temperatures as low as 20°F, and uses up to 60% less cooling capacity. ASCENDANT promotes efficient mechanical system operation via higher coil air discharge and central plant suction temperatures, which facilitates performance that surpasses ASHRAE 90.1 building energy, ASHRAE 170 ventilation, and ASHRAE 62.1 indoor air quality (IAQ) standards. Latent loads are, in majority, addressed by economical hot water, steam, waste heat, or direct gas-fired regeneration energy, facilitating 50-75% greater efficiency when compared to conventional DX dehumidifiers with electric compressors.

Further energy savings can be realized via integration of SEMCO’s on-board, integrated direct digital control (DDC), which optimizes system operation and space condition management to achieve flexible air temperatures and relative humidity.

ASCENDANT has been recognized with a 2016 AHR Expo Innovation Award, an annual competition honoring inventive and original products, systems, and technologies showcased at the AHR Expo.
