The PSH panel is a specialized control system designed by one of our clients and currently manufactured by SIOS as part of an ongoing collaboration.

This panel is used in cryogenic tank installations to prevent the release of product in its liquid phase. It does so by alternating the operation between two vaporizers using programmable timers—allowing one vaporizer to operate while the other undergoes a defrost cycle. This ensures continuous and safe gas supply without service interruptions.

In addition, the panel includes a temperature monitoring controller at the gas outlet. When the system detects a drop in temperature below the operational threshold, both vaporizers are automatically activated to prevent any risk of discharging liquid-phase product.
