OptiChill FreeCool Specifications OptiChill FreeCool The OptiChill FreeCool is a large capacity, low energy R134a air-cooled screw chiller that meets diverse cooling loads with a flexible, low sound cooling solution. Highly energy efficient, the OptiChill FreeCool offers more than 95% free-cooling over a year (cumulative hours, London, UK) and can save more than 50% of the energy consumed by a conventional chiller thus greatly reducing operational costs. For up to 30% of the year, the OptiChill FreeCool can operate purely in free-cooling mode, leading to Free-cooling EER's* of up to 75....

OptiChill FreeCool Energy savings Energy saving benefits EER1 up to 3.06 ESEER2 up to 3.44 > Free-cooling virtually all year round > Two sizes of free-cooling coil (2 and 3 rows) for increased annual efficiencies > Economisers, each with dedicated EEV, to enhance compressor performance at full and part load operation (option) > Electronic expansion valves increase ESEER by 30% > Interactive head pressure setpoint management to achieve optimum EER > Closed transition avoids high transient changeover current peaks (option) > EC fan for ultimate system efficiency (option) > Compressor power...

OptiChill FreeCool Features and options Key feature: Modulating screw compressors to match cooling load Top-of-the-range twin screw compressors offer high performance coupled with low sound and vibration levels. The compressors offer eight stages for optimum efficiency, performance and reliability and are complemented by optional economisers to produce a significant increase in cooling capacity. Optimised for part load, the compressors give an improved ESEER and are applied in a way that ensures system design is fully integrated and the efficiency is maximised. The increased operating...

OptiChill FreeCool Features and options Key option: Electronically commutated (EC) fans* Offered as an option in the OptiChill FreeCool for ultimate condenser efficiency at full and part load, cleverly-designed axial fans use the latest electronically commutated (EC) motor technology. EC technology combines AC and DC voltages to bring the best of both technologies and give increased performance at reduced power input. At certain conditions an EC fan gives energy savings of more than 80% compared with an AC fan. Featuring low motor temperature, the EC fan has a longer life than an AC...
