Redundant Walk-In Freezers

A redundant refrigeration system is a cold storage unit equipped with two independent refrigeration systems operating in tandem, so that if one system experiences a failure, the second can continue maintaining temperature without interruption. In practice, one system runs as the primary and the other as a backup, with both synchronized to share run time evenly and protect the integrity of stored products. This design is particularly important for industries where even a brief temperature excursion can result in product loss, regulatory non-compliance, or patient safety risk.

A standard walk in freezer operates with a single refrigeration system. If that system fails, there is no built-in backup to prevent temperatures from rising until a service call is completed. A redundant walk in freezer, by contrast, is equipped with two independent refrigeration systems so that cooling continues even if one unit goes offline.

Redundant walk in freezers and coolers are best suited for operations where a temperature excursion could result in significant product loss, regulatory violations, or a risk to patient safety. Pharmaceutical companies, clinical research organizations, vaccine distributors, and food manufacturers with high-value or irreplaceable inventory are among the most common users. Redundant systems are also a sound choice for any business operating under FDA GMP regulations, USP Chapter 1079 guidelines, or other cold chain compliance frameworks that call for backup refrigeration as part of a risk mitigation plan.

Our DT820RP Redundant walk in Cooler and Freezer features two independent condensing units with a KE2 Therm controller installed on each evaporator coil. The two controllers are synchronized so that both systems share run time evenly, with one operating as the primary and the other as an active backup. If the primary system goes offline, the backup engages to maintain temperature while service is arranged. This design also supports 24/7 remote monitoring, with real-time temperature data, alerts, and control accessible via the KE2 platform.

Our DT820RP Redundant walk in Cooler and Freezer is engineered for customers with precise temperature requirements, with operating capabilities ranging from 35°F (2°C) down to -10°F (-23°C) and lower depending on configuration. That range covers refrigerated storage as well as standard and deep-frozen storage needs, making the unit versatile across pharmaceutical, food, and biological applications. If your products require a specific temperature target or a validated temperature range, we can confirm the appropriate configuration before delivery.

Yes. Our redundant cold room units are temperature validated, and our validation reports are available to provide documented evidence of consistent performance within specified temperature tolerances. Validation documentation can serve as a baseline for your own qualification process, and our units are designed to support IQ/OQ/PQ protocols required by FDA GMP and USP Chapter 1079 compliance frameworks. Each unit also supports 21 CFR Part 11-compliant data logging, which is essential for pharmaceutical customers managing audit trails and regulatory documentation.

Our redundant walk in units arrive fully pre-assembled and require only a single electrical connection to begin operating, with no on-site refrigeration work, hard wiring, or diesel generator needed. Delivery timelines vary based on your location and current fleet availability, but our national distribution network is designed to get units on-site quickly, including for urgent or emergency situations.
