Functional description

Adequate, clean, and dry gas flow at the seal governs seal reliability. During normal operation, this is achieved by taking product gas from the compressor high-pressure stage or discharge, flowing it through filter(s) and using it to flush the seal cavity. When the compressor slows and comes to a pressurized standstill, the gas flow is interrupted and leaves the seal(s) unprotected against contaminated product gas. This poses a serious risk, because unfiltered product gas leaves deposits in the primary seal cavity, which causes high seal leakage and even seal failures. To alleviate this problem, the RoTechBooster CX draws gas from the compressor and flows it through filters delivering a clean and dry gas to the seal(s) when seal gas flow must be produced.

Unlike other seal gas boosters that require additional skids to house the needed instrumentations, fittings, and tubing to make them appropriate for installation, the RoTechBooster CX already has all the necessary components included.
All that is required:

1. Inlet supply
2. Outlet back to seal gas panel
3. Power supply - with soft start
4. Signal connections
5. Logic to initiate operation.

It has never been cheaper and easier to incorporate a seal gas booster into your seal gas system.

GSS Gas supply system

Gas supply systems of the GSS range are specially designed for contact-free operated, gas-lubricated mechanical seals. The gas supplied from the supply network (e.g. air or nitrogen) is regulated/monitored by the GSS in accordance with the requirements of the seals being supplied. The GSS systems are equipped with alarm and/or switch-off points depending on specific safety requirements. Centralized monitoring of the measurement values is also possible on request.
