Pressure equalisation
Thermatek® technology can help you to regulate airflow, ensuring smooth door operation, structural integrity, and energy efficiency.
The issue
The hidden risk of pressure imbalances in cold storage
Cold storage facilities rely on airtight insulation, but this can create dangerous pressure imbalances that impact performance and safety. Without proper ventilation, pressure fluctuations can lead to:
- Door sealing issues, making it difficult to open or close freezer doors
- Structural stress, causing damage to walls and insulation panels
- Energy inefficiency, increasing refrigeration system workload
The science behind pressure changes
- Rapid temperature shifts: Every time a freezer door opens, warm air enters and cools rapidly, reducing internal air volume.
- Vacuum effect: As air contracts, negative pressure makes doors difficult to open and puts stress on seals.
- Condensation and ice formation: Unregulated airflows introduce moisture, leading to frost buildup inside freezers.

Reliable heating systems to prevent frost heave and condensation.
Thermatek approach
Why pressure equalization valves are essential
Thermatek® pressure equalization valves (PEVs) provide a controlled way to balance internal and external air pressures. These engineered vents:
- Prevent excessive pressure differences, ensuring smooth door operation
- Protect structural integrity, reducing strain on walls and panels
- Minimize moisture infiltration, lowering the risk of ice and frost formation
Backed by industry research
- Research from the International Refrigeration and Air Conditioning Conference highlights that pressure fluctuations contribute to cold storage inefficiencies and higher maintenance costs.
- Studies from the Institute of Building Physics confirm that proper ventilation prevents excessive condensation and frost buildup.
The Thermatek® advantage
Our precision-designed pressure equalization valves provide reliable, low-maintenance performance:
reducing strain on door mechanisms
preventing frost-related failures
ensuring continued operation
built for industrial use.
Ensure reliable cold storage performance
Don’t let pressure imbalances disrupt your operations. Thermatek® pressure equalization valves are the simple, effective solution to prevent door failures, structural stress, and energy losses.
