Pressure equalisation valves (PEVs)
Thermatek® PEVs protect cold storage by regulating airflow, preventing door lockups and structural damage.
The product
Product information
Thermatek® Pressure Equalisation Valves (PEVs) are essential components for maintaining the structural integrity and functionality of cold rooms and freezers. Designed to equalize internal and external pressures, PEVs prevent common issues such as doors becoming impossible to open or structural damage caused by pressure imbalances.
Pressure fluctuations can occur due to various factors, including defrost cycles, temperature changes during freezer operation, door usage and ambient temperature variations. Thermatek® PEVs efficiently manage these changes, ensuring reliable and safe cold storage operations.
Innovative design
Independent testing has confirmed that the Thermatek® PEV outperforms other commercially available products, supporting larger cold stores due to its superior airflow efficiency.
Key design features:
- Simple installation: designed for effortless mechanical and electrical installation, ensuring seamless integration into cold store environments.
- Durable construction: crafted from high-quality ABS (for freezer interiors), stainless steel, and aluminum, the PEV is built to withstand harsh conditions, requires minimal maintenance, and is easy to clean.
- Sleek design: engineered for aesthetic compatibility, its clean, modern design complements the professional appearance of any cold store.
- Trace heating: low power inexpensive heating to ensure flawless operation.
Optimal sizing and installation
To ensure effective pressure equalization, the number of Thermatek® PEVs required is calculated based on freezer volume:
- Small Freezers (<1000m³): One PEV is sufficient
- Larger Freezers: Install two PEVs for every 1400m³. Add two additional valves for resilience and to accommodate external fluctuations (e.g., blocked airflow).
Example Calculation:
For a freezer of 4200m³ at -20°C:
Required PEVs = (4200 ÷ 1400) + 2 = 3 + 2 = 5 PEVs
Safety and longevity
Thermatek® PEVs are designed with safety and durability in mind:
- Secure power connections: connections for the trace heating are made externally, at the rear of the unit, for improved safety and ease of access
- Hygienic materials: the internal face is crafted from ABS, and internal components are stainless steel or aluminum, eliminating the risk of rust or paint contamination
- Effective sealing: an O-ring seals the unit to the freezer wall, allowing any condensation to drain externally and maintaining a clean, dry interior
Thermatek® Pressure Equalisation Valves combine innovative design, robust materials, and precise engineering to ensure dependable performance and long-term value.
