Tender Specification SyScroll 140-360 Air CO / HP 1 General description SyScroll Air EVO CO / HP / RE units have been designed and optimized to operate with R410A refrigerant and scroll compressors Thanks to multi-scroll technology and asymmetric design in refrigerant circuits, it is possible to reach very high level of full load efficiency (EER up to 3,2 and COP up to 3,3) and seasonal performances (ESEER up to 4,3), in line with Ecodesign requirements SyScroll Air EVO CO units are available in 9 sizes, w
Tender Specification SyScroll 140-360 Air CO / HP • Low Noise (L): the units are equipped with star connected fans implying lower rotation speed. Besides lower fan deck sound emission, the chillers are supplied with compressors box to reduce the noise emissions • Super Low Noise (S): the units are equipped with star connected fans, fitted with a speed controller which allows the units to operate with a very low rotation speed.
Tender Specification SyScroll 140-360 Air CO / HP • Total Heat Recover (TR version): double circuit plate type heat exchanger to recover the total heat rejected to the condensers.
Tender Specification SyScroll 140-360 Air CO / HP version • Control platform Modular architecture, compressor envelope integration, corrective actions in border line areas, easy-friendly user interface • Several options / accessories provided with standard delivery: o Phase sequence control safe electric installation o Electronic expansion valve precision in SH control o Control circuit transformer power supply without neutral o Control data logger thermodynamic parameters recording o Water diffe
Tender Specification SyScroll 140-360 Air CO / HP 4 Compressors Compressors are of hermetic scroll type and fitted with an electronic control system ensuring protection against high temperature and excessive load. All compressors have direct-on-line starting and are mounted on rubber vibration isolators in order to minimize noise and vibration transmission 5 Evaporator Indoor heat exchangers are brazed stainless steel plate type.
Tender Specification SyScroll 140-360 Air CO / HP 6 Condenser Condenser coils are made of seamless copper tubes, arranged in staggered rows, mechanically expanded into corrugated aluminum fins. In Cooling only version (CO) condenser coils are microchannel type, made of 100% aluminium (fins, tubes and headers) with the exception of copper pipe couplings. Additional surface coating is provided for the standard delivery in order to further improve resistance to corrosion.
