Medium pressure range
The PLH series refrigerated dryers is designed for compressed air networks up to a pressure of 50 bars needing a pressure dew point of +3ºC.
They are equipped with stainless steel plate heat exchangers. These heat exchangers offer a better resistance and take up less space than traditional ones.
The cooling circuit is regulated by a proportional valve, guaranteeing a dew point stability from 0 to 100% of the flow.
The range comprises 19 models covering flows of up to 5000m3/hr.
• 3ºC pressure dew point (ISO 8573-1:2001=4 class)
• stainless steel brazed plate heat exchanger
• vertical design of the heat exchanger, natural separation of the water through gravity, without risk of backflow
• condensate separator with stainless steel demister
• digital display of the dew point
• electronic controller with configurable remote alarm monitoring
• low energy consumption
• low clutter
• electronic condensate drain
* Select the generic if you don't know which model to choose. The sales department will contact you to determine the appropriate model.
(*) ISO 7183 - 20ºC 1 bar abs. for a pressure of 40 bar, compressed air 35ºC, ambient air 25ºC, pressure dew point +3ºC.
PLH: Medium pressure range
The PLH series refrigerated dryers is designed for compressed air networks up to a pressure of 50 bars needing a pressure dew point of +3ºC.
The thermodynamic circuit is designed around a robust stainless steel brazed plate heat exchanger. These heat exchangers offer a better resistance and take up less space than traditional ones.
A proportional regulation bypass valve offers a perfect stability to the cooling circuit and a constant dew point , without freezing risk, regardless of the dryer’s load.
The dew point is constantly displayed for a better control.
