Rittal has introduced a low noise TopTherm Plus rack air-conditioning unit for office environments. The new unit features low noise fans, which avoid the need for water-cooling. Units are currently available for applications up to 750W, and are also equipped with the new Condensate Management System (CMS). CMS collects the condensate and evaporates it back into the external atmosphere via a heating element and new routing tube. Available on fast delivery times, the new coolers run on 230V or 115V 50/60Hz. Dimensions are compatible with any rack equipped with RS232, RS485 and RS422 for on-line connectivity.
