LAMBDA DX/DXU

Product catalog summary

Overview: The document provides detailed information about the Lambda DX/DXU precision air conditioning systems by Kaltra Innovativtechnik GmbH, designed for mission-critical applications with high energy efficiency and flexibility to meet complex requirements.

Specifications: The Lambda DX/DXU units offer cooling capacities ranging from 35 to 95 kW with an Energy Efficiency Ratio (EER) of up to 4.06. They feature dual refrigeration circuits with scroll compressors and microchannel heat exchangers, ensuring precise control of temperature, humidity, and airflow.

Design and Construction: The units are constructed with a robust, lightweight frame using aluminum components, ensuring durability and airtightness. The modular design reduces parts by 30%, facilitating easy integration into data center infrastructures and reducing costs.

Refrigeration and Airflow: Each unit includes two independent refrigerant circuits with electronic expansion valves (EEVs) for optimized refrigerant flow. The use of microchannel evaporators reduces refrigerant charge and enhances efficiency. New radial fans with EC motors provide quiet operation and energy efficiency.

Control and Monitoring: A sophisticated microprocessor controls the units, allowing local or remote management. The system supports various control strategies, including continuous temperature, airflow, and pressure control, and can configure multiple units simultaneously.

Options and Accessories: The units offer a range of standard and optional features, including steam humidification, dehumidification, EC fans, touch screen HMI, backup power supply, and various connectivity options (BMS, SNMP, GSM).

Technical Data: The document includes detailed technical specifications for different models, including cooling capacities, power input, airflow rates, and dimensions. The units are designed to operate efficiently under specified temperature and humidity conditions.

Conclusion: The Lambda DX/DXU air conditioning systems provide a reliable and efficient solution for critical environments, offering flexibility, high performance, and reduced total cost of ownership.

Heat exchangers High performing microchannel evaporators combined in A-form Lambda units based on newly developed all-aluminium microchannel heat exchangers with an advanced design that combines high-performance flat tubes, state-of-the-art airside fins, and low-pressure drop headers. The unique geometry of the manifolds and refrigerant distributors make it possible to feed the microchannel tubes equally for evaporation and ensures consistent and predictable heat transfer. Vertically-oriented microchannel tubes allow free condensate water shedding. Lambda family of precision air conditioners...
