Product detailed description
The RDS-1150 refrigeration dryer dries compressed air to a pressure dew point of +3 °C, i.e. water class 4 according to ISO 8573-1. It handles 19,167 l/min (1,150 m³/h) at 7 bar, operates at up to 16 bar and connects via a female thread G 2 1/2"; power supply 400/50 V/Hz.
It belongs to the Omega Air RDS refrigeration dryer range with R513A refrigerant, an automatic zero air loss condensate drain and a controller that displays the dew point.

Dimensions
Dimensions according to the manufacturer: width A 662 mm, depth B 856 mm, height C 1534 mm; weight 250 kg. The dryer is moved by forklift.
Flow rate under other conditions
The nominal flow rate of 19,167 l/min applies to +25 °C room temperature, +35 °C inlet temperature, 7 bar and +3 °C dew point. Under other conditions, multiply it by the manufacturer’s correction factors. For example, at 10 bar, +40 °C inlet temperature and +30 °C room temperature, the RDS-1150 handles 19,167 × 1.14 × 0.83 × 0.96 = 17,410 l/min.

How it works
The air passes through the three-stage heat exchanger module: the dried air pre-cools it, the refrigerant in the evaporator cools it so that the water vapour condenses, the demister separates the water droplets and the drain discharges them. The dry air is warmed up again at the outlet, so no moisture condenses on the pipework.
Equipment
The automatic condensate drain discharges water without air loss. The controller displays the dew point and signals alarms; the dryer communicates via MODBUS and can be switched on and off remotely. The refrigerant circuit is protected by a temperature switch and a pressure switch.
R513A refrigerant
R513A refrigerant has zero ozone depletion potential and low global warming potential, and it has replaced the former R134a refrigerant.
Position in the system
The dryer goes downstream of the compressor and air receiver. Install a 3 µm pre-filter upstream of it, for example one of the basic compressed air filters; downstream, depending on the required purity, install a fine pre-filter and a microfilter. For a dew point below 0 °C, you need a desiccant dryer.
Accessories
Bypass piping is not supplied for this size.
