GTS 114 Gas Turbine Intake Filter Test System
High-flow test system for gas-turbine and rotary-machinery intake filters, combining particle, salt and water-endurance testing under adjustable temperature and humidity conditions.
Model Overview
| Model | System purpose | Standards / method | Core fit |
|---|---|---|---|
| GTS 114 | High-flow conditioned-air test system for gas-turbine and rotary-machinery intake filters | ISO 29461-1, ISO 29461-2, ISO/AWI 29461-4, ISO 16890-2/-3/-4, ASHRAE 52.2 | Particle efficiency, salt removal, dust holding and water-endurance testing |
Key Features
ISO 29461 workflows
Configured for gas-turbine intake-filter testing, including water endurance and salt-removal evaluation.
Controlled air conditions
Circulation mode enables adjustment and stabilisation of test-air temperature and humidity.
Multiple aerosol challenges
Introduces NaCl, KCl, DEHS and standard test dusts into an optimised flow profile.
Water and vapour loading
Automated feeding of water droplets and supersaturated vapour supports endurance procedures.
Flexible filter formats
Accommodates cassettes, pocket filters, cartridges and flat media.
High automation level
Operator-guided, mostly automated sequences support repeatable data and documentation.
