LWN Type Hydrociat HPS Chillers
Crystal Air was recently engaged in supplying and commissioning two Hydrociat air cooled chillers to deliver 800kW of chilled water for the new offices at 1 Kilmainham Square, Dublin 8. The main challenge was to deliver an air cooled system within the confides of the basement to comply with local planning in the area.
A high power system (HPS System) ensures that each circuit has an increased cooling capacity an a higher EER which facilitated a small footprint for the main chilling plant. These units were coupled to four heat-rejection condensers from the CIAT Concept AHU range with inverter speed-controlled condenser fan motors to ensure low noise operation and maximum energy efficiency.
The complete Hydrociat range is available from 270kW to 1420kW and is designed and manufactured to ISO9001 Quality Managment Systems. It is also certified to Eurovent norms.
The extensive range of Hydrociat chillers can meet a wide variety of liquid cooling environments and comply with all applicable standards in respect of ozone layer protection limiting the greenhouse effect. Various versions cater for different applications in offices, housing, hotels, industrial processes etc
Evaporators, with two or three refrigerant circuits and one hydraulic circuit, were specially developed by CIAT for the Hydrociat range. Making connection on site is simple. The flow switch and al the sensors required for correct, safe operation are fitted, tested and adjusted in the factory. Each Hydrociat chiller is supplied with a transformer fitted on the control panel which single mains supply, with no neutral, is all that is required.
Thanks to the unique design of the heat exchangers and their high exchange coefficients - plus the compact accessible hermetic compressors with integrated oil separators - Hydrociat units are extremely compact. Their reduced footprint means that additional space can be made available in the plant room for other equipment. They are also easy to install.
The compressors used allow a wide operating range with a particularly high performance. Despite their high capacity and with compressors part-winding and cascade control starting, they still keep an acceptable starting current.
The small number of parts, high-quality components (such as auronautical bearings), optimised oil management and maximum continuous motor cooling, means longer life for all Hydrociat units. The fact that the units require no servicing or heavy maintenance is an additional plus factor for installers and clients alike
