A dehumidifier system for regenerating a dissicant wheel by means of steam and a dehumidifier comprising said system

A dehumidifier system (200,300,400) and a dehumidifier comprising said dehumidifier system (200,300,400), said dehumidifier system (200,300,400) comprising

• a rotary desiccant wheel (210) comprising a silica gel;
• a supply gas flow path (220) for supplying a supply gas to an adsorption section (211) of said rotary desiccant wheel (210) defining thereby an upstream side (221) and a front side (215) of said rotary desiccant wheel (210), and a downstream side (222) and a backside (216) of said rotary desiccant wheel (210);
• and
• a closed regeneration loop (240,340,440) for regenerating said rotary desiccant wheel (210) using superheated steam;
• and
• said closed regeneration loop (240,340,440) comprising
• at least one means for circulating superheated steam (250,350,450) in said closed regeneration loop (240,340,440),
• at least one steam superheater (260,360,460),
• at least one diversion flow path (270,370,470) for diverting a flow of excess superheated steam from said closed regeneration loop (240,340,440) to at least one process element of interest (280), said at least one process element of interest (280,380,480) being a heat exchanger (380) or a heat driven cooling unit (480);
• and
• wherein said closed regeneration loop is operated at a regeneration operating temperature of said superheated steam from 110° C. to 200° C.
