GWVT Series

GWVT Series Special and Process Gas Screw Compressors

The GWVT Series Special and Process Gas Screw Compressors are designed for process gas compression applications that differ from conventional compressed air systems. Equipment configurations can be tailored to the properties of the specific gas, working pressure, flow rate, and project operating conditions.

The series offers working pressure ratings of 0.8 MPa, 1.0 MPa, and 1.25 MPa, covering a range of motor power ratings and FAD capacities. The technical documentation also provides specifications for cooling water inlet and outlet connection sizes, cooling water requirements, overall dimensions, weight, and gas outlet connections.

Special and process gases may vary significantly in composition, temperature, pressure, corrosiveness, flammability, and process requirements. Therefore, the final GWVT model should not be selected solely on the basis of general product specifications. Complete gas composition and operating condition data should be provided for each project so that technical personnel can confirm the appropriate equipment configuration.

Note: This table has been extracted from the original GWVT product documentation and follows the existing “one model per row” web table structure. For each model, the 0.8 / 1.0 / 1.25 MPa pressure ratings and their corresponding FAD ranges are arranged vertically within the same cells, maintaining the order shown in the original table. The “Lubricating Water Requirements” column contains no values in the original documentation, so the corresponding cells in the web table have been left blank without adding any assumed values. For the GW250VWR model, the cooling water inlet and outlet connection sizes and cooling water requirements are displayed on two lines in the original table. These entries have been preserved as presented, without making additional assumptions about their individual correspondence to the three pressure ratings.

Selection Guide

Among the six product series, the GWVT Series requires the most extensive preliminary information before equipment selection.

The first step is not to select the motor power rating, but to identify the gas to be compressed, including its name, main components, concentration range, and whether liquids, particles, or other accompanying substances may be present.

The following operating parameters should then be determined:

Inlet pressure → Required outlet pressure → Actual required flow rate → Inlet temperature → Continuous or intermittent operation.

The pressure ratings and FAD ranges in the specification table can then be used to shortlist suitable base models.

Different process gases may impose different requirements on materials, seals
