The Q-Lab Q-SUN Xe-3-HDSE Flat-Array Xenon Arc Test Chamber with RH and Dual Spray is a full-size xenon arc weathering tester for laboratories that need controlled full-spectrum light, temperature, relative humidity and advanced spray capability. The Xe-3-HDSE model uses three 1800 W full-spectrum ozone-free xenon arc lamps, a large flat-array specimen tray, SOLAR EYE irradiance control and dual spray capability. It is designed for technical buyers testing coatings, plastics, automotive materials, textiles, packaging, sealants, printed materials and selected three-dimensional components where sunlight, heat, humidity and liquid exposure must be simulated under repeatable laboratory conditions. For laboratories comparing Q-SUN Xe-3 configurations, the Xe-3-HDSE adds dual spray to the humidity-controlled Xe-3 platform, while excluding back spray and chiller functions.
Test Standards Supported
The Q-SUN Xe-3-HDSE supports xenon arc weathering and lightfastness methods where the selected cycle requires irradiance, chamber air temperature, black panel or insulated black panel temperature, relative humidity and spray capability. Exact method suitability depends on the selected optical filter, irradiance control point, temperature setpoint, RH setpoint, spray cycle and required fluid exposure.

Specimen Capacity and Configuration
The Q-SUN Xe-3-HDSE uses a large flat-array specimen tray with a 45 x 72 cm exposure area and capacity for 55 specimens at 51 x 102 mm. The near-horizontal 10° specimen orientation is useful for flat panels, coated coupons, plastics, textiles, packaging samples and selected three-dimensional parts. Q-Lab notes that Xe-1 and Xe-3 specimen capacities are listed without specimen holders, so holder selection should be confirmed during configuration.
The key difference between Xe-3-HSE and Xe-3-HDSE is the dual spray system. Q-Lab notes that the Xe-3-HDSE has a separate water reservoir that requires additional floor space. This makes the model suitable for laboratories running more advanced spray programmes than a standard front-spray configuration, while still avoiding the added chiller system used on C models. If the test method requires water exposure on both sides of the specimen, a back spray configuration should be reviewed.
Operating Specifications
The Xe-3-HDSE is an S model, so it requires high-purity water. Q-Lab lists the water requirement for all S or W models as inlet pressure of 2.1 to 6.2 bar, resistivity greater than 5 MΩ.cm, conductivity less than 0.2 μS/cm, total dissolved solids less than 0.1 ppm and colloidal silica less than 0.1 ppm. Q-Lab also recommends pH 6 to 8 and use of a reverse osmosis/deionisation system for best performance.
For facility planning, the Xe-3-HDSE main chamber external dimensions are 91 x 178 x 99 cm, with a listed weight range of 190 to 233 kg depending on configuration. Additional floor space should be allowed for the separate water reservoir required by the Xe-3-HDSE dual spray configuration. Q-Lab notes that the rear Xe-3 vent duct can be removed to reduce chamber depth from 99 cm to 88 cm for movement through small doors.
The electrical requirement for Xe-3-HDSE is 208 V or 230 V, 3-phase at 39 A, or 400 V, 3-phase at 26 A, with voltage tolerance of plus or minus 10% and 50/60 Hz operation. The recommended laboratory ambient condition is 23 ± 5 °C and 50 ± 25% relative humidity. Q-Lab states that operation outside these conditions can cause temperature, humidity or other faults, and the chamber should not be operated above 36 °C ambient or above 80% RH.
Why Choose the Q-Lab Q-SUN Xe-3-HDSE?
The Q-Lab Q-SUN Xe-3-HDSE is a strong choice for laboratories that need a full-size Xe-3 flat-array chamber with humidity control and dual spray capability, but do not require back spray or chiller operation. Compared with Xe-3-HSE, it adds dual spray. Compared with Xe-3-HBSE, it focuses on dual spray rather than back spray. Compared with Xe-3-HSCE, it avoids the chiller system where lower chamber air temperature operation is not required.
For technical buyers, the main commercial value is advanced spray capability in a large flat-array platform. The Xe-3-HDSE combines three air-cooled xenon lamps, SOLAR EYE irradiance control, humidity control, BP or IBP plus CAT control, dual spray, AUTOCAL calibration and a large specimen tray. This supports repeatable, documented weathering and lightfastness testing for R and D, formulation comparison, supplier qualification, quality control and customer specification work.
