At SUNPASS, we understand completely why ISO tank owners and operators should never compromise on the quality of their gaskets and seals. While they may seem like a small component, their role is absolutely critical to the safety and efficiency of your operations. Our years of experience and unwavering commitment to quality have shown us just how vital a single gasket can be.

A compromised gasket doesn’t just lead to a small leak; it can result in:

• Leaks of hazardous or valuable cargo
• Costly downtime and emergency maintenance
• Environmental and safety violations
• Damage to customer trust and brand reputation

For us, the gasket is the tank’s first line of defense. It ensures a secure seal under extreme pressure, temperature, and chemical exposure. Using substandard or incompatible gaskets can quickly turn a routine operation into a crisis.

Remember, a tank is only as reliable as its weakest component. Don’t let that be the gasket. At SUNPASS, we eliminate this risk with the superior quality products we provide.

How it works?

1. Initial Assessment:

The ISO tank is checked to ensure it’s structurally sound and free of any contaminants. 

2. Nitrogen Injection:

Nitrogen gas is introduced into the tank, usually through a dedicated connection, displacing the existing atmosphere. 

3. Purging Process:

The nitrogen flow is maintained until the oxygen content within the tank reaches a safe level, typically below 1%. 

4. Monitoring:

The pressure and oxygen levels are continuously monitored to ensure the purging process is effective. 

5. Final Check:
