Cold Room & Walk-In Unit Monitoring for Healthcare Facilities

A single sensor in a large cold room leaves blind spots. PharmaWatch deploys multiple sensors across every zone — so a temperature drift in any corner of your cold room is caught immediately, not when someone walks in and finds the problem.

One System. Monitoring, Compliance, Protection.

Full Coverage. No Blind Spots.
Multiple sensors deployed across every zone of your cold room — corners, shelving units, high-traffic areas. If temperature drifts anywhere in the space, your team is alerted immediately. Not when someone walks in and finds the problem.

Automated Compliance Records
Every reading from every sensor logged automatically with a timestamp. Every alarm documented with a user ID and resolution note. Joint Commission, FDA, and State Board of Pharmacy-compliant records — built continuously, no manual entry required.

Up and Running in Minutes
Sensors ship pre-configured. Plug them in and monitoring starts immediately — no IT, no WiFi, no setup. Most facilities have their entire cold room covered the same day equipment arrives.

Built for large cold storage environments

What We Monitor

Every critical parameter across every zone of your cold room or walk-in unit — tracked continuously so a drifting corner or a failing door seal never catches you off guard.

Temperature
Continuous zone-by-zone monitoring across the full cold room, 3-5-minute readings per sensor
Humidity
Relative humidity monitored continuously across storage zones
Differential Pressure
Monitored for pharmaceutical cold rooms and controlled storage environments where pressure differentials are required
Open Door Detection
Every door open event logged with timestamp and duration. Extended openings trigger immediate alerts.
Flood & Wetness Protection
Water intrusion detection in cold room flooring and storage areas
Power Status
Immediate alert on power loss with 5-day battery backup per sensor
Every facility is different. Your monitoring should be too.

Why we’re different

There’s a Reason Facilities Choose Us.

No False Alarms When Staff Enter

Cold rooms are accessed constantly. Every time the door opens, air temperature spikes and standard sensors alarm. Staff learn to silence it — and that’s how real excursions get missed. PharmaWatch’s patented VTB™ models actual product temperature, not ambient air. Alarms only fire when it actually matters.

Catch Refrigeration Problems Before They Escalate

A failing compressor in a cold room doesn’t just risk one unit — it risks everything stored in it. PharmaWatch tracks refrigeration system performance patterns and flags struggling equipment weeks before failure, giving you time to act before your entire inventory is at risk.

Frequently ask a questions

Find the answers here

How many sensors do you recommend for a cold room?
It depends on the size and layout of your cold room. PharmaWatch recommends a sensor deployment that covers every distinct zone — particularly corners, areas near doors, and high-density storage shelving where temperature variance is most common. Our team will recommend the right sensor count and placement for your specific space during your demo.
How does PharmaWatch eliminate false alarms when staff enter the cold room?
PharmaWatch’s patented Virtual Temperature Buffering™ (VTB™) models actual product temperature rather than ambient air. When the cold room door opens, air temperature spikes momentarily. VTB™ filters these events so alarms only fire for genuine excursions — not routine access.
Can PharmaWatch detect when a cold room door is left open?
Yes. Open door detection is built in. Every door open event is logged with a timestamp and duration. If a door is left open beyond a configurable threshold, your team is alerted immediately before temperatures are affected across the space.
What happens if the power goes out?
Built-in 5-day battery backup keeps every sensor running independently of your facility’s power grid. Your team is alerted immediately via call, text, or email. When power returns, all timestamped data syncs automatically. Zero gaps in your compliance record.
Does PharmaWatch work without WiFi?
Yes — entirely on cellular. No network credentials, no firewall changes, no IT involvement. Monitoring keeps running during WiFi outages, IT maintenance, and power interruptions.
What compliance standards does PharmaWatch support for cold room monitoring?
Joint Commission, FDA 21 CFR Part 11, FDA GxP and cGMP, AABB, USP 797/800, CDC VFC, and State Board of Pharmacy. IQ/OQ/PQ validation documentation is included in every deployment at no additional cost.
How does calibration work for cold room sensors?
ISO 17025 pre-calibrated replaceable probes with a 2-year calibration interval. Replacement probes ship automatically before expiration — swap in seconds, monitoring stays continuous. NIST-traceable certificates permanently linked to each device record in the portal.
Can PharmaWatch monitor cold rooms across multiple facilities?
Yes. Multi-site deployments from one centralized dashboard. Every cold room, every sensor, every zone visible in real time — compliance reports for any location in 3 clicks, from any device, anywhere.
