Blue Line ASB

HANSA's exhaust air side evaporative cooling Blue Line ASB has been a successful model since its introduction: Your investment and operating costs are very low compared to the mechanical cooling and allow a cooling of the outside air up to 13 Kelvin (see figure below).

The HANSA ASB system uses rigidly mounted nozzles, which allow a comprehensive and uniform exhaust air side humidification of the double plate exchanger used. In conjunction with increased corrosion protection of exposed components, the system therefore becomes durable and low-maintenance.

With appropriate design, which we guarantee, our Blue Line ASB units meet the ErP Directive according to Regulation (EU) 1253/2014.

The Blue Line ASB units are individually configured and designed according to the air conditioning task to be fulfilled. Due to our modular HKG design, the series of equipment can be individually expanded with the necessary components in each case: integrated mechanical cooling or heat pump (also reversible), cold or hot water register, humidification and dehumidification, etc.
