This document is an engineering specification sheet and product documentation for Liebert CW floormount chilled water systems supplied to the U.S. Embassy in London, England.

The specification details two Liebert CW Model CW106DC1G2A254 chilled water units ordered on July 1, 2014, by B.L. Harbert International for delivery to the U.S. Embassy in London. The units feature 415/3/50 voltage with 5,000 amps RMS short circuit current rating, total cooling capacity of 488,300 BTU/hr (131.3 kW) net capacity, and sensible cooling of 448,100 BTU/hr (131.3 kW) net capacity. Key components include a 4-row aluminum coil with copper tubes, 2-way chilled water control valve (150 psig/1,034 kPa rated), EC motorized impeller fans operating at 16,800 CFM with 0.2 inches ESP at 0-1000 feet altitude, three 4.15 HP motors, MERV 11 filters with 2-inch pre-filters, optional infrared humidifier with auto-flush capability (22.1 lbs/hr capacity, 9.6 kW), and optional electric reheat (102,390 BTU/hr, 30 kW). The control system includes iCOM large graphic display with supply air sensor and English language interface, IS-UNITY-DP card for network connectivity, smoke sensor, LT410 point leak detection sensor, LT460-Z30 zone leak detection sensor, dual float condensate pump, and standard 24-inch floorstand. Cabinet dimensions are 122 inches wide × 35.6 inches deep × 76 inches height, weighing 1,785 lbs. The unit is equipped with non-locking disconnect switch, factory-installed based on 415/3/50 voltage specification, and includes domestic packaging with protective covering and corner buffers. The documentation comprises engineering specifications, performance rating sheets showing cooling capacity analysis, electrical schematics, dimensional drawings, piping connection details, and product specification literature for integrated Liebert monitoring and control components.
