The Explovent Relief Port is designed to equalise pressure changes within Medium and Low Temperature Rooms and Blast Chillers. Pressure changes caused by temperature fluctuations and door operation can place stress on insulated panels, atmospheric seals and refrigeration systems. The Explovent Relief Port provides reliable pressure equalisation to help protect panel integrity, maintain efficiency and reduce ice buildup. Available in sizes from 100mm to 300mm and designed for refrigeration pressure equalisation applications.

Pressure Relief Port Sizing Guide
Selecting the correct pressure relief port size is important for maintaining effective pressure equalisation within cold rooms and blast chillers.
Frequently Asked Questions
Why Use A Pressure Relief Port?
Pressure changes occur naturally within refrigerated environments.
As temperatures change and doors are opened and closed, pressure differentials develop inside the room. If these pressure changes cannot equalise effectively, they can contribute to:
- Panel movement and stress
- Atmospheric seal failure
- Ice buildup
- Reduced operating efficiency
- Increased maintenance requirements
The Explovent Relief Port helps minimise these issues by allowing pressure to equalise safely and consistently.
How many pressure relief ports do I need for my cold room?
The number of pressure relief ports required depends on the room type and internal volume.
Low Temperature Room:
1 Relief Port per 40m³ of internal room volume
Blast Chiller Room:
1 Relief Port per 20m³ of internal room volume
For larger rooms, additional relief ports should be installed based on the total internal room volume.
Where should a pressure relief port be installed?
Pressure relief ports are typically installed high on a wall or ceiling and positioned away from direct evaporator airflow.
What size pressure relief port do I need?
Sizing depends on room volume and application. Refer to the sizing guide above or contact JAV Industries for assistance.
Are Explovent Relief Ports suitable for blast chillers?
Yes. Explovent Relief Ports are suitable for blast chiller applications and can be sized according to room volume requirements.
Are they Australian Made?
Yes, JAV Industries manufactures the Explovent Relief Port in Australia for the Australian refrigeration industry.
