PLH series (high pressure dryers for compressed air systems up to 50 barg) makes the most of manufacturing and functional advantages of brazed plate heat exchangers, which are more suitable for high pressure working conditions (on models PLH 15-500). All the stainless steel plate heat exchangers used are manufactured by primary companies and are specifically designed for air dryer applications and certified for high pressure (up to 50 barg). The refrigerant circuit and demister type condensate separator are projected and dimensioned to increase dryer performance, and comply to the 97/23/CE-PED directive.

Main characteristic are:
1. simple and ergonomic component layouts guarantee functionality and efficiency;
2. final performance is excellent due to low pressure drop and to constant pressure DewPoint;
3. dryer design is very attractive both aesthetically with a two tone cabinet and practically with a rounded profiles robust casing (on models PLH 15-330).
