Understanding the Essentials of Warehouse Temperature Control
Warehouses in all manner of different industries need to have controlled environments. You might be working with food, sensitive technology, pharmaceuticals or general industrial equipment. Whatever sector you operate in, your warehouse temperature is one of the most significant things for you to keep an eye on.
Warehouse temperature control requires a multifaceted approach that includes HVAC optimisation, creating a proper building envelope and a general understanding of thermodynamics. This article gives more actionable insights into how to establish a properly temperature-controlled warehouse, whether it’s a primary imperative or just to enhance an already functional environment.
Dealing with the air stratification challenges of warehouse temperatures
Warehouse temperature monitoring and control are a lot more complicated than they are in a residence or smaller workplace. Warehouses with high ceilings generally deal with air stratification, meaning the roof is likely to be 10–15°C higher than the temperature at the floor.
The solution is to install high-volume low-speed fans (HVLS). They don’t work by cooling the air, but rather by destratifying it by pushing the warmer air down and mixing it with the rest, creating a more uniform temperature across the space.
It’s also worth understanding that concrete floors act as something of a heat sink, which is why certain modern warehouses might install radiant tubing into flooring slabs. This allows operators to use the entire floor as a heating or cooling element.
How to stop your loading dock from leaking
The loading dock or loading bay is likely to be the biggest enemy to your warehouse temperature control, as it’s a regularly opening space where hundreds of pounds of treated air can escape. That’s why it’s important to properly set the dock up to maintain temperatures over extended working hours.
- Proper doors, such as insulated roller shutter doors or sectional models will help to keep temperatures consistent. Fast acting, smoothly operating doors ensure that doors are open for less time, resulting in less temperature loss.
- Dock seals and dock shelters are essential for creating a physical gasket between trucks/trailers and the building, ensuring deliveries and pickups don’t cause major temperature loss.
- Air curtains can be used to create an invisible wall, blocking around 80% of air transfer, keeping bugs and heat out while letting forklifts pass through.
It’s vital to manage the loading bay or dock as comprehensively as possible, whether following warehouse temperature regulations for pharmaceutical study or a retail operation.
Modern warehouse temperature control technology
There are more forms of temperature technology beyond the HVLS fans and loading dock installations that warehouse operators should keep in mind.
- Evaporative cooling technology uses the enthalpy of vaporisation to cool air using water pads, ideal for dry climates and high-heat manufacturing sites.
- Chilled water systems circulate cold water through heat exchangers, perfect when fitted in heavy machinery sites or major catering operations.
- Spot cooling directs refrigerated air directly to specific workstations, which is ideal for companies with assembly lines or contained furnace sections.
- CO2 monitoring tools should be used in industrial settings, prioritised above temperature control to ensure safety in working hours.
- The entirety of the temperature control in a warehouse should be run through a building management system (BMS), allowing for thermostat control and so much more.
It’s worth doing an audit of your current technological suite, as this will act as an actionable guide on what you need to install and incorporate moving forward.
From the doors on your loading bays to the software/hardware that you manage the building with overall, warehouse temperature control takes a broad stroke approach. And make sure to regularly check each installation for potential improvements or savings.
