DCL centrifugal chillers and magnetic-bearing selections — Moon-Tech

Datasheet

Product overview

Power: 300–2000 RT · DCL single head · Pressure: Chilled water 12 / 7°C · Flow: Cooling water 32 / 37°C · DCL

Moon-Tech's HVAC catalog presents DCL centrifugal chillers as a Dunham-Bush product line. The DCL page lists a single-head cooling range of 300–2000 RT and a twin-head range of 600–4000 RT, with entering/leaving chilled water at 12/7°C and cooling water at 32/37°C. RT describes cooling capacity rather than motor power or compressed-air delivery. Tie the offered chiller to its legal seller, brand, assembly location and current model documentation.

The DCL description identifies HFC-134a refrigerant and CCS TOUCH controls, with ice-storage and heat-recovery functions available for selection. Specify which functions the quotation includes and request the current refrigerant and destination-compliance documents. The catalog range is not a guarantee of the selected machine's performance at other water temperatures.

A separate magnetic-bearing centrifugal chiller page lists 100–900 RT, with 12/7°C chilled water and 30/35°C cooling water. It describes two-stage compression, magnetic bearings, direct drive and variable-speed operation. This alternative has different cooling-water conditions from DCL; compare both at an agreed duty. Its separate heating-duty entries are not cooling-capacity ratings.

For a project, send peak and part-load cooling requirements, entering/leaving water temperatures, water flow and quality, electrical supply, site layout and redundancy. Obtain full/part-load input data, pressure drops, stable operating range, control/BMS interfaces and installation/service access. Itemise tower or other heat-rejection equipment, pumps, treatment, controls, commissioning and spares separately from the chiller supply.
