COLD STORES


Reducing pharma temperature-control risk


Pharmaceutical operations depend on precise temperature control across process cooling, controlled environments, and cold storage. Temporary cold store solutions they must do more than provide refrigerated space. Dave Palmer, district leader UK and Ireland, ICS Cool Energy explains.


F


ew industries demand precision like pharmaceuticals. From process cooling and cleanroom support to fi nished-product storage,


temperature control infrastructure must perform reliably under changing conditions while supporting product quality, regulatory compliance, and operational continuity. Process chillers form a critical part of that infrastructure. Optimised for demanding use, they provide a reliable solution that not only supports continuity of process but adapts rapidly in response to fl uctuations in system demand, helping maintain stable, precise temperature control at all times and under varying operating conditions. Against this backdrop, temporary cold stores are


rarely used as simple overfl ow space. More often, they are deployed to solve a specifi c operational challenge: protecting temperature-sensitive product during planned maintenance, supporting refurbishment of existing cold rooms, creating temporary additional capacity, or providing separate storage conditions for testing and stability work. In deep-frozen and ultra-low-temperature applications in particular, a temporary cold store can be more practical than attempting to replicate permanent infrastructure with a temporary chiller-based arrangement on site.


The objective is always clear – to preserve product integrity, maintain controlled conditions, and reduce the risk of excursion, deviation, and batch loss when permanent infrastructure is unavailable or under pressure.


Why use temporary cold stores Permanent cold rooms remain central to pharmaceutical operations, but they do not solve every short-term challenge on site. Temporary cold stores and freezer containers are used across a broad range of pharmaceutical cold chain applications, including vaccine storage and distribution, biologics and biosimilars, temperature-sensitive enzymes, clinical trial materials, blood plasma, biological samples, and temporary manufacturing backup during shutdowns, refurbishment, maintenance, or peak production periods. They are also relevant across multiple storage


regimes, from controlled-temperature applications in the +2°C to +8°C range through frozen and deep- frozen storage to ultra-low-temperature applications such as -70°C, depending on the product profi le, process requirement, and risk level of the material being stored.


In pharmaceutical manufacturing and life sciences


operations, cold stores are typically used in a set of well-defi ned operational scenarios. These include: ■ planned maintenance, refurbishment or replace- ment of refrigeration infrastructure, when product must be protected while permanent cooling systems or cold rooms are taken offl ine


■ temporary expansion, where additional con- trolled-temperature capacity is required during peak production, site reconfi guration, or shifts in inventory profi le.


■ testing and stability work, where operators need a separate temperature-controlled environment without disrupting validated permanent storage.


They also fulfi l an important business continuity


role, either as live backup or as contingency capacity in the event of permanent equipment failure or power disruption. This is especially relevant where the stored materials include high-value fi nished products, intermediates, biologics, plasma, enzymes, investigational materials, or deep-frozen inputs for later manufacture. In such cases, the temporary cold store is not simply a space solution; it is a controlled, documented, and dependable part of the site’s wider risk-control and continuity strategy.


Redundancy is the critical diff erentiator From a pharmaceutical perspective, the principal diff erentiator between a standard refrigerated container and a pharma-specifi ed temporary cold store is redundancy. In pharma, compared to other
