Cold room rentals
Polar Leasing’s temperature controlled cold room rental units are walk-in combination freezer/refrigeration units specifically designed and engineered for customers operating in the pharmaceutical cold chain. Each custom-built cold room has an option for rental validation. For added efficiency and to further protect the integrity of the products stored inside, each cold room rental features vinyl strip curtains to reduce the amount of cold loss or heat gain.
Temperature-controlled cold rooms for rent
Polar Leasing currently supplies cold rooms for rent to many pharmaceutical companies involved in temperature-sensitive distribution. Polar Leasing cold room storage rentals are the perfect on-site solution for temporary refrigeration anywhere throughout the cold chain, for everything from research & development and clinical trial phases to the logistics of pre-conditioning gel packs & PCMs prior to transport.

Polar Leasing and Phase Change Materials (PCM)
Phase Change Materials (PCM) are ideal for holding pharmaceutical products at precise temperatures during transport, but in order to maintain the low temperatures required, they must first be charged. Polar Leasing’s cold room storage rental units are designed achieve temperatures as low as -22°F / -30°C , allowing them to charge PCMs and prepare them for transport.
Benefits of PCMs
- Maintain precise temperatures
- Reach and maintain sub-zero performance
- Temperature ranges: 0°c (32°f), -7°c (19.4°f), -16°c (3.2°f), and -21°c (-5.8°f).
- Reusable and non-toxic
- Maintain low temperatures 3-5x’s longer than ice or dry ice.
Frequently Asked Questions
When does it make sense to rent instead of buy a cold room?
Renting often makes sense when you need extra capacity for a defined period, want to avoid a large upfront purchase, or test the right size and configuration before making a long-term commitment. Renting can also help you stay flexible as demand changes across R&D, clinical trials, production, and distribution.
What temperature range can a portable cold room maintain for pharmaceutical cold chain storage?
Our temperature-controlled cold room rentals are designed for pharmaceutical cold storage needs and can reach 0°F down to -22°F (about -18°C to -30°C). That range supports frozen conditioning and other sub-zero cold chain workflows where temperature control is critical. These units are also designed to achieve temperatures low enough to charge phase change materials used in transport.
How is a pharmaceutical cold room different from a refrigerated trailer or shipping container?
A pharmaceutical cold room is purpose-built for stationary, compliant storage with features designed for temperature stability and hygiene. Refrigerated shipping containers were designed for transport and often lack the tight temperature control that GMP and other regulations require.

What does validation mean when talking about pharmaceutical cold room rentals?
Validation is documented proof that a cold storage system has been methodically tested to maintain temperature within required tolerances across defined conditions. Our validation process includes factory testing steps such as visual inspection, 24-hour empty-unit thermal mapping, open-door recovery testing, and power failure testing at multiple setpoints. Validation documentation can help reduce compliance risk by providing a baseline of performance before you complete site-specific qualification.
How can cold room rentals support temporary cold storage for compounding pharmacies?
Compounding pharmacies often need cold storage that holds tight temperature tolerances through frequent door openings, busy periods, and cleaning cycles. Our pharma cold storage guidance highlights the need for reliable, audit-ready temperature documentation and fast replacement capacity when uptime matters. When you need to scale up quickly, temporary cold rooms can add capacity without waiting for construction or permanent expansion.

What size cold room storage rental units does Polar Leasing offer?
Our temperature-controlled cold room rentals are offered in 8×10 and 8×20 sizes, with customers typically evaluating footprint, access needs, and storage volume when choosing the right unit size. If you have unique space constraints or throughput requirements, we can help match the right unit to your workflow.
What monitoring and alarm options are available for Polar Leasing cold rooms?
We support remote monitoring and can track real-time temperature, door activity, and defrost cycles. KE2-equipped units provide 24/7 control, alerts, and data access. Cloud monitoring with SMS and email alerts is also available. If you have a gap in monitoring records, we can help provide tracked data for troubleshooting or documentation.
Do you offer rental units for ambient temperature storage or humidity-controlled testing?
Yes. Our ambient temperature walk in unit maintains a stable room-temperature environment between 65°F and 80°F (18°C to 27°C), which is ideal for pharmaceuticals and life science products that don’t require refrigeration. For stability, shelf-life, or quality testing, we also rent stability chambers with precise temperature and humidity control to simulate environmental conditions over defined test periods.
