In-house psychrometric testing laboratory, engineered and built by Q-Corporation, USA for performance tests on Air Handling Units, Fan Coil Units, Split Air Conditioners & Roof top package Units.

Test simulations can be conducted at Trosten’s laboratory as validation of equipment’s actual performance at project specified conditions.

Testing complies to the following international standards:

  • EN 1886
  • AHRI 430, AHRI 440, AHRI 410, AHRI 340 / 360
  • ASHRAE 41.1, 41.2, 41.3, 41.6
  • ASHRAE 79 & 37
  • ISO 5151
