Purolite manufactures the ion exchange and affinity resins used in different separation, purification, and decontamination processes, with applications ranging from water softening to the purification of biopharmaceuticals. These products are specialised and highly valuable and need to be stored at precise temperatures in fridges and freezers. Purolite also stores large quantities of chemicals at specific temperature and humidity levels in warehouses which, until recently, had to be manually checked by staff every day.


KoolZone partner, GPE Scientific, is a long-standing advisor and supplier of life science and chemistry equipment to Purolite’s UK R&D Centre of Excellence in South Wales. 

Patrick Gilbert, Technical Director, Agarose at Purolite Life Sciences commented, ‘GPE Scientific made me aware of new technology that could take the onus off staff and provide round the clock monitoring of every asset on our estate, alerting us to fluctuations in temperature and humidity in time to fix a situation before it becomes serious. This meant we would no longer have to worry about what was happening out of hours, a particular vulnerability when we were doing checks manually’.



GPE recommended KoolZone’s IoT-based (Internet of Things) sensors, gateways, and monitoring software. KoolZone’s technology is long-range, wireless, and low power. Patrick Gilbert, ‘This was of particular interest to me because we wanted an inexpensive and flexible solution that allowed us to monitor and reconfigure our assets without major upheaval’.

After a demonstration showing how the sensors capture data via a cellular gateway that can be accessed from any mobile device, KoolZone mapped the relevant sensors to a plan of Purolite’s facility. KoolZone’s long range (LoRa) technology meant the whole configuration works using a single router.


Patrick continues, ‘It became evident to me that KoolZone was exactly what we needed, I purchased a range of temperature sensors for our fridges and freezers and temperature and humidity sensors for the warehouses. There is no software or wiring to install, simply place the sensor where you want it, login, and access the data. I set-up alarms so I am notified by text if an asset falls out of a set temperature range. Furthermore, I can generate reliable reports quickly, I don’t have to wait for the old manual checks that were so prone to human error. Before long KoolZone highlighted an ongoing issue with an old freezer, which we replaced before it failed, saving us time and money’.

Patrick says he would recommend the GPE Scientific-KoolZone solution, ‘It gives my colleagues and I peace of mind, which is hard to put a price on’.
