The SBTP 408, rotary, twin-screw compressor offers variable volume ratio. A hydraulically actuated slide stop adjusts slide valve position to optimize internal discharge pressure. This matches compressor volume ratio to system pressure ratio and eliminates the power penalties associated with under- or over-compression.
The SBTP compressor models utilizes API compliant journal bearings and tilting pad thrust bearings to absorb radial and axial loads respectively. The cylindrical sleeve bearings are oil grooved for optimal lubrication and higher radial load capability. The tilting pad thrust bearing uses offset pads and directed lubrication to minimize power loss and maintain lower bearing temperatures at lower oil flows for maximum bearing life.
