The Hailos S23 dual cooling source precision air conditioner is a room-level unit rated 24.5 kW total cooling and 22.0 kW sensible cooling, with a second cooling source capacity of 18.2 kW in the same cabinet. It is designed for computer rooms that need a fallback cooling path without installing a second machine: one cabinet carries the direct expansion circuit and the second cooling source, and the duty is shared or switched according to the room requirement.
The S series cabinet is compact, fully front access, and fitted with variable speed AC/EC rear tilt centrifugal fans as standard. On this model the maximum external static pressure is 235 Pa for downward air supply and 220 Pa for upward air supply, so it can feed a raised floor plenum or a short duct run without losing air volume.
Direct expansion cooling plus a second cooling source rated 18.2 kW share one cabinet, one controller and one power feed. Sensible heat ratio is 0.90 and energy efficiency ratio is 2.16, with maximum total power consumption of 14.9 kW.
R410A is the standard charge. R134a, R407C and R513A are available on the same cabinet with factory set expansion valve, pressure settings and controller parameters.
Vortex (scroll) compressor with safety devices, designed for frequent start-up and long term continuous operation of precision constant temperature and humidity systems.
Variable speed AC/EC rear tilt centrifugal fans, dynamically balanced as a complete assembly before delivery, cutting fan power consumption by about 35% and keeping noise at 53.9 dB(A) for downward air supply and 54.6 dB(A) for upward air supply.
Hydrophilic aluminium fin with high efficiency internally threaded copper tube for corrosion resistance and long service life; ALCO expansion valve for high sensitivity and easy replacement.
Electrode humidifier with 9 kg/h capacity using tap water directly with automatic cleaning, 12 kW PTC ceramic heater, and reusable metal frame G4 plate filter.
All service points are reachable from the front face, so maintenance is possible in a narrow aisle without moving the cabinet. Air supply method can be switched on site.
