Specialising in fast, accurate diagnostic tests for the management of infectious and genetic diseases The Molecular Diagnostic Unit (MDU) specialises in providing fast, accurate diagnostic tests for the management of infectious and genetic diseases. Our CPA-accredited unit uses the latest technology, including next generation sequencing and UPLC to provide an unparalleled service to our national and international customers. The academic Department of Genitourinary Medicine (GUM) and Retrovirology which houses the MDU also encompasses a Clinical Trials Centre (CTC) and The National Centre for Human Retrovirology (NCHR). Many of the assays developed for the MDU were designed to support the HIV and HTLV trials undertaken by the CTC and to optimise management of patients attending the NCHR and the Imperial College Healthcare Trust. The academic department is constantly researching and developing new diagnostic methods which, once validated, can be introduced into clinical service via the MDU.

This allows us to remain ahead of the field in diagnostic testing and clinical monitoring and to provide the highest quality of patient care. Our work is particularly centred on HIV, hepatitis viruses and sexually transmitted infections, but we are happy to collaborate with you in designing and producing assays for your particular clinical requirements.

In Partnership with the Center for Digital Research and Scholarship at Columbia University Libraries | Terms of Use | Advanced Dual Circuit Cooling for Data Center Applications Liebert DS data center cooling system provides efficient, precise, reliable control of room temperature, humidity and airflow for proper operation of critical electronic equipment. The flexible Liebert DS offers high energy efficiency, user-friendly Liebert iCOM controls, modular frame, front service access, and compressor and fan options. Liebert DS is offered in downflow models from 28-105kW (8-30 tons) capacities and upflow models in 28-105kW (8-30 tons) sizes.

The system is available in 60Hz and 50Hz.​​ Precision cooling and humidity control Provides component redundancy compressors, motors and blowers Offers multiple configurations and sizes for flexible application Monitors and controls operation with Liebert iCOM Allows installation in upflow or downflow configuration, and in Air, Water, Glycol, GLYCOOL economizer models. Offers ultra energy efficient GLYCOOL economizer and Dual Cool hybrid models. Downflow models compatible with optional air economizer. Offers ultra energy efficient GLYCOOL and Dual Cool hybrid models. ​Flexibility Allows installation in upflow or downflow configuration, and in Air, Water, Glycol, GLYCOOLâ„¢ models. Provides a complete environmental control package, including both precision air conditioning and humidity control. Offers a choice of compressors, including Digital Scrollâ„¢, scroll and semi-hermetic four-step models. Provides flexible cooling capacity via variable capacity compressors.

Requires only front access for service. Installs easily due to modular frame construction. Brings high-level supervision with Liebert iCOM controls, allowing networking of multiple mission-critical cooling units. Features reliable refrigeration components, including dual compressors, A-frame evaporator coils, all factory pre-piped, wired, and tested. Offers new Copeland Digital Scrollâ„¢ Compressors stepless variable capacity control for ultimate control and reliability. Provides redundancy with dual refrigeration circuits. Lowest Total Cost Of Ownership Exceeds the most stringent government efficiency requirements with NEMA premium efficiency motors. Offers energy efficient EC fans on downflow configurations. Industrial process control centers Other sensitive electronic applicationsDoes the Liebert DS cost more to operate than a regular building air conditioning system? Specifically designed for the demanding requirements of year-round operation, the Liebert DS is actually less expensive to operate over its life cycle compared to both comfort cooling equipment and competitive precision air conditioning products.

Does this type of cooling system use a lot more energy? No, due to a greater sensible heat removal capability compared to a comfort cooling system of the same size, the Liebert DS will save money and even pay back part of your investment over the life of the system. What if you don't have a raised floor in your data center? The Liebert DS is available in upflow models for use in facilities without raised flooring, as well as downflow models designed to be used with raised floors. Why is a Liebert DS precision cooling system better than ordinary building air conditioning? The Liebert DS offers a much higher level of reliability compared to comfort cooling systems. It uses rugged refrigeration components that are designed to operate 24 hours a day, 365 days a year. The Liebert DS also provides the precise temperature and humidity control required by sensitive electronic computer equipment.Contact your local Liebert NA Representative at your location.
