The PRZ 18 is the proven entry-level model in the INHAG professional rescue tent series. With a floor area of 4.09 x 4.60 m (19 m²) and a weight of 73 kg, it is the most compact PRZ in the portfolio—and also serves as the basis for the DZ PRZ 18 decontamination tent.
The dual-circuit safety system, consisting of two pneumatically separate air chambers, is the central feature of the entire PRZ series: In the event of a complete loss of pressure in one air circuit, the remaining support frames remain functional—the tent retains its shape, enabling an orderly evacuation and immediate repair. This is complemented by the self-erecting feature: Two longitudinal air cylinders in the base area automatically erect the tent after unpacking—a second person is not required to roll it out.
The roof and walls are made of PVC-coated polyester fabric (300 g/m²), which is flame-retardant in accordance with DIN 4102 B1. The removable PVC floor covering is secured with Velcro. Eyelets for lamps, IV bags, and accessories are attached to all longitudinal and transverse beams of the frame. The tent is available in seven standard colors at no extra charge.
