| High Light | R410A multi refrigerant precision AC ，S35 downflow CRAC unit 380V ，data center precision AC supplier | ||
The Hailos S35 is a room-level precision air conditioner from the S series, rated 37.0 kW total cooling and 35.1 kW sensible cooling, built for computer rooms and data halls that need constant temperature and humidity all year round. R410A is the standard factory charge; the same cabinet can be supplied with R134a, R407C or R513A when a project specification or local import rule requires it.
The S series was developed for energy efficiency, compact footprint and low noise. The electronic speed regulation fan cuts fan power consumption by about 35%, the fan is placed above the coil on downflow models to improve airflow through the evaporator, and the full frontal design allows all service work from the front face.
R410A is the default charge for global availability and stable service cost. R134a, R407C and R513A are released on the same cabinet, with the expansion valve, pressure settings and controller parameters configured at the factory, so a specification change does not require a new unit design.
Two vortex (scroll) compressors with safety devices deliver high efficiency, low noise and long service life, and support the frequent start-up and continuous operation duty of precision cooling.
Each unit is fitted with variable speed AC/EC rear tilt centrifugal fans as standard, dynamically balanced as a complete assembly before delivery. Fan power consumption is reduced by about 35% and there is no need to consider pressure equalisation when units are combined.
High efficiency internally threaded copper tube with hydrophilic aluminium fin, giving corrosion resistance, long life and high heat transfer. ALCO expansion valve is used for sensitive and easily replaceable regulation.
The electrode humidifier uses tap water directly, has an automatic cleaning function and can be serviced without shutting the unit down. Heating is by PTC ceramic electric heater, 18 kW on this model.
Filters, fans, humidifier cylinder and controller are all reachable from the front face. The cabinet footprint is among the smallest in this capacity class, and the air supply method can be switched on site between underfloor and upward supply.
