Pfannenberg Adjustable Hygrostat, Snap Mount, 230 V AC/DC, FLZ 610 Series 17218100000

Pfannenberg 17218100000 Adjustable Hygrostat, part of the FLZ 610 series, is a precision control device designed for industrial and commercial HVAC and thermal management systems. Suitable for maintaining relative humidity levels in control cabinets, it prevents condensation and corrosion by activating fans or heaters when preset humidity thresholds are exceeded.

This hygrostat combines both thermostat and humidity sensing functions in a single compact housing, providing independent monitoring of temperature and humidity. It features a snap mounting style which simplifies installation and servicing in electrical enclosures.

With an adjustable humidity setting range of 40% to 90% RH and a switching temperature difference of approximately 2K, it ensures tight control over environmental conditions. The device supports a maximum supply voltage of 230 V AC/DC, making it highly compatible with various industrial power arrangements. It is rated IP20 for protection against accidental contact and foreign objects, suitable for indoor industrial applications.

The Hygrostat operates reliably between temperatures of -20°C to 0°C, making it suitable for colder environments requiring precise humidity control. Its robust construction meets BS EN, ANSI/ESD, and RoHS standards, reflecting high quality and compliance with environmental directives. The compact form factor with dimensions 80.5mm height, 59mm width, and 38mm depth facilitates integration into limited space control panels.

Adjustable humidity range from 40% to 90% RH. Snap mounting type for easy fitting. Max supply voltage 230 V AC/DC. IP20 protection class. Operating temperature between -20°C and 0°C. Switch configuration: Changeover (CO).
