Built on the design approach used in the current range, Lambda DX/DXU II offers improved efficiency driven by all-new segmented microchannel evaporator coils and the latest radial fan technology.
With two fully independent refrigeration circuits, the new Lambda DX/DXU II provides high reliability for mission-critical applications and 35% more cooling than its previous generation.
In fact, Lambda DX/DXU II system is a 2-in-1 air conditioner where two independent refrigeration systems share common controls and a case. Beyond reliability, this allows customers for on-the-fly maintenance without system shutdown.
Sixteen basic models will be offered in total. The range offers a cooling capacity of 20 to 115kW for units with integrated fans and 25 to 130kW for units with separate underfloor fan compartments (gross capacity for 24°C/45%rH inlet air). The control system is set for operation with an inlet air temperature range of 25°C to 45°C.
The system is targeted for serving thermal-sensitive applications such as clean rooms, metrology, measuring and other laboratories, precise manufacturing, medicine, museums, data center-grade cooling, and other areas with a concentrated heat load.
Lambda cooling units can run on refrigerant R410a and later on lower GWP refrigerants in Q4 2022-Q1 2023 – after the European Commission’s scheduled revision of EN 378 in 2022.
In sum, Lambda DX/DXU II offers a large set of advantages if compared to preceding precision air conditioning systems:
- Offers high availability for critically temperature-controlled environments
- Delivers improved cooling efficiency
- Requires less refrigerant charge
- Allows maintenance without service interruption
- Provides maximum versatility in installations
Lambda DX/DXU II is compatible with both CxM condensers configurable for vertical and horizontal airflows and high-performance LCC series of air-cooled condensers. The latter provides lower condensation temperatures, adding to energy savings. An expanded operating envelope of LCC condensers allows ambient temperatures of -35°C (with low-ambient kit ordered) to +55°C.
