Features
Pressurized barrier system (closed circuit) for use in seal systems with high pressures and/or for hazardous/environmentally harmful processes.
The SPC6000A4 (API Plan 53C) range is available with a pressure booster, cooler (finned tube, water or air cooler with fan) and a wide range of instruments.
A refilling unit must be provided.

Advantages
- Pressurization occurs by means of a pressure booster
- Automatic setting of the barrier pressure via reference pressure:
simple and reliable mode of operation - Safe operation even in case of pressure changes
- Barrier pressure is created without any need for connection to a nitrogen supply
- Available with finned tube, water or air coolers with fan
- Modular system: combination with a wide range of system components/instruments possible
Standards and approvals
- API 682 / ISO 21049

Functional description
The SPC6000A4 is designed to perform the following functions of a barrier system:
- To pressurize the buffer chamber
- As leakage compensation
- To cool the seal
Pressurization (> process pressure) prevents the process medium from getting into the barrier circuit or the atmosphere. Circulation in the barrier circuit occurs via the thermosiphon principle or by forced circulation, e.g., with a pumping screw.
