AutomationDirect now offers STEGO enclosure heaters, thermostats, hygrostats and hygrotherms to protect against condensation while providing the greatest possible air circulation. Touch-safe convection heaters are designed to utilize natural convection, resulting in a circulating current of warm air while minimizing surface temperatures on the accessible side surfaces of the housing. The compact, DIN rail-mountable units are available in 12 to 30V AC/DC and 120 to 140V AC/DC models and with heating capacities ranging from 10W to 150W (depending on model).
Touch-safe convection heaters start at $24.25. Fan heaters with an operating voltage range of 100 to 120VAC are available in screw-mount and DIN rail-mountable versions as well as panel-mount and foot-mount models. Designed with high-performance axial fans, the units provide forced air circulation to prevent the formation of condensation and ensure evenly distributed air temperatures. Screw-mount and DIN rail-mount units have heating capacities of 150W to 650W (depending on model) while panel-mount and foot-mount versions have 950W or 1200W heating capacities. Panel-mount and foot-mount models are designed with integrated adjustable thermostats and built-in overheat protection. Fan heater prices start at $86.75. DIN rail-mountable enclosure thermostats have also been added. Tamperproof styles available in normally-open and normally-closed models feature fixed set points and are available in single and dual versions. Adjustable thermostats available include single units in normally-open and normally-closed models as well as dual units containing one normally-open and one normally-closed thermostat with separate color-coded adjustable temperature controls. Thermostat prices start at $12.
Electronic hygrostats sense relative humidity and activate the enclosure heater at a setpoint to help prevent the formation of condensation within the enclosure. Available in two models (120VAC and 230 VAC), the DIN rail-mountable electronic hygrostats feature adjustable relative humidity setpoints (40% to 90% RH), high switching capacity and a visual function display. Hygrostat prices start at $55. Electronic hygrotherms provide efficient temperature and humidity control. With a temperature setting range of 32℉ to 140℉ and a humidity range of 50% to 90%, the unit is designed with a high switching capacity and optical function display. The hygrotherm senses the ambient temperature and relative air humidity. The unit then turns a connected device either on or off if either the temperature is below or the humidity is above the set point. Hygrotherms are priced at $82.75. LED lights suitable for panels and enclosures have also been added. Available with either On/Off switch or motion sensor, and in magnet-mount and screw-mount versions, the powerful output allows up to 10 lights to be connected together. LED light prices start at $67.50.
