Klinge's Explosion-Proof Refrigerated Container Model PFR-571 ZII-II was designed for operation in hazardous Zone 2 locations.  The unit complies with the ATEX Directive 94/9/EC level of Ex II 3 G, Group IIA. Every component in the evaporator section is explosion proof, since this section is in direct contact with the cargo area. All external parts are also explosion-proof. The PFR-571 ZII-II was designed for 20' and 40' Insulated ISO Containers.

Defrosting of the evaporator coil is done with our unique and well proven “On Demand” hot-gas system, when required. The “On demand” defrost system assures that the optimal time for defrosting is chosen, which then assures that the maximum refrigeration time is obtained. In other words the defrost is not governed by a timer but by a sensor, sensing the heat transfer capabilities of the evaporator coil, so defrost is not started too early or too late.

The PFR-571 ZII-II is used to transport hazardous chemicals, resins, adhesives, pharmaceuticals, ammunition and other goods requiring extra protection. Klinge has been providing this model to major chemical and pharmaceutical companies around the world for nearly 30 years.

Klinge's machinery complies with International Customs Regulations for Containers, relevant ISO recommendations, and the rules of B.V., ABS and Lloyds.
