Kaltra Innovativtechnik, a German-based provider of innovative thermal management technologies and advanced cooling equipment, today released the Lambda DX/DXU family of the feature-rich, high-end direct expansion (DX) precision air conditioners with the innovative microchannel evaporators and dual refrigerant circuit amongst many of its features.
With a capacity range from 30 to 95kW, the energy efficiency of the newly developed cooling units (EER) reaches a maximum of 4.06.
Lambda DX air conditioning units based on newly developed microchannel evaporators with advanced design that combines high-performance flat tubes,state-of-the-art airside fins and ultra-low-pressure manifolds with integrated refrigerant distributors.
The unique geometry of the manifolds and refrigerant distributors make it possible to feed the microchannel tubes equally for evaporation and ensures consistent and predicted heat transfer. Vertically-oriented microchannel tubes ensure free condensate water shedding.
In combination with doubled area shaped design, microchannel evaporators permit multiple advantages to be achieved, including low airside pressure drops, higher cooling capacity, remarkably less weight and reduced refrigerant charge.
With two independent refrigerant circuits each connected to its own microchannel evaporator, Lambda DX/DXU allows maintenance tasks to be carried out with the cooling system at power.
Each refrigerant circuit is equipped with an electronic expansion valve (EEV) which has the function of regulating and optimizing the refrigerant quantity to the evaporator according to the current needs.
Lambda DX features a refrigerant leak detection system, which is becoming a high priority for many customers, especially considering the potential for loss of inventory if a major leak renders a cooling system inoperable.
