Precision air conditioner

Kaltra launches new range of high-efficient precision air conditioners

Kaltra Innovativtechnik, a Germany-based provider of innovative thermal management technologies and advanced cooling equipment, today released the Lambda DX/DXU family of feature-rich, high-end direct expansion (DX) precision air conditioners with innovative microchannel evaporators and dual refrigerant circuit amongst many of its features.

With cooling capacity ranging from 30 to 95kW, the energy efficiency (EER) of the newly developed cooling units reaches a maximum of 4.06.

Lambda DX air conditioning units are based on newly developed microchannel evaporators with an advanced design that combines high-performance flat tubes, state-of-the-art airside fins, and inlet manifolds with integrated refrigerant distributors.

The unique design of inbuilt refrigerant distributors makes it possible to feed the microchannel tubes equally for evaporation and ensures consistent and predicted heat transfer. Vertically-oriented microchannel tubes ensure free condensate drainage.

Combined to double the heat transfer surface, microchannel evaporators permit multiple advantages to be achieved, including low airside pressure drops and consequentially low fan power consumption, higher cooling capacity, remarkably less weight, and reduced refrigerant charge.

With two independent refrigerant circuits, each connected to its own evaporator, Lambda DX/DXU allows maintenance tasks to be carried out at power, without service interruption. 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 detector, 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.

Kaltra is a world-known provider of cooling technologies and advanced cooling products for mission-critical applications, such as data centers, clean rooms, contaminant-free areas, processing plants, and other facilities where reliability and energy efficiency are key factors. Kaltra’s cooling equipment range includes precision cooling systems, air-cooled and water-cooled chillers, evaporative cooling solutionsdry coolers, and condensers.
