The STI-7521-HTR STI Heated Polycarbonate enclosure features integrated heating technology and thumb lock security for reliable equipment protection in cold environments. The durable polycarbonate construction maintains clarity for visibility while the heating element prevents condensation and ice buildup on critical fire safety equipment. The thumb lock mechanism provides quick access for authorized personnel while deterring unauthorized tampering. Ideal for outdoor installations and unheated facilities requiring year-round operational reliability.

These enclosures are perfect for safeguarding a variety of devices, components, and sensitive equipment against vandalism, accidental impacts, and exposure to harsh elements such as weather, dust, dirt, and grime. Engineered to maintain the internal temperature above freezing, these covers enable the protected equipment to be installed outdoors, in freezers, or in unheated storage areas and warehouses. The integrated radiant heat plate ensures LCD screens remain responsive and do not freeze, operating on 12, 16.5, or 24 VAC/VDC power sources. The STI-7510-HTR and STI-7511-HTR models come with an external thumb or key lock and offer two different enclosed back box options. The STI-7520-HTR features a key lock, while the STI-7521-HTR is equipped with a thumb lock.
