The Q-Lab Q-SUN Xe-3-HDSCE Flat-Array Xenon Arc Test Chamber with RH, Dual Spray and Chiller is an advanced full-size xenon arc weathering tester for laboratories that need controlled full-spectrum light, temperature, relative humidity, second-liquid spray capability and lower chamber air temperature operation. This extended Xe-3 Model E configuration combines humidity control, dual spray and a separate chiller in Q-Lab’s flat-array Xe-3 platform. It is designed for technical buyers testing coatings, plastics, automotive materials, textiles, packaging, sealants, printed materials and selected product components where degradation is driven by light, heat, humidity, spray chemistry and temperature-sensitive exposure conditions. For laboratories comparing Q-SUN Xe-3 configurations, the Xe-3-HDSCE adds chiller capability to the humidity and dual spray platform, while excluding the back spray function used on HDSBSE and HDSBSCE models.
Test Standards Supported
The Q-SUN Xe-3-HDSCE 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, spray capability and lower chamber air temperature operation. Exact suitability depends on the selected optical filter, irradiance control point, temperature setpoint, RH setpoint, spray cycle and test fluid requirements.

Specimen Capacity and Configuration
The Q-SUN Xe-3-HDSCE 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 testing 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 configuration advantage of Xe-3-HDSCE is its combination of dual spray and chiller capability. Dual spray supports a second spray liquid, while the chiller supports lower chamber air temperature operation. This makes the model useful for advanced weathering programmes where standard water spray is not sufficient and where lower temperature control is required for temperature-sensitive materials or specific customer methods.
Operating Specifications
The Xe-3-HDSCE 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 main Xe-3 chamber external dimensions are 91 x 178 x 99 cm, and the chiller dimensions are 78 x 94 x 94 cm. The dual spray system includes a separate reservoir and pump enclosure, so additional floor space should be allowed for the full installation. 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-HDSCE is 208 V or 230 V, 3-phase at 44 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-HDSCE?
The Q-Lab Q-SUN Xe-3-HDSCE is suited to laboratories that need a full-size Xe-3 flat-array xenon arc tester with RH control, dual spray and lower temperature capability. Compared with Xe-3-HDSE, it adds chiller-supported operation. Compared with Xe-3-HSCE, it adds dual spray for a second liquid. Compared with Xe-3-HDSBSE, it excludes back spray, so it is best aligned where dual spray and chiller are needed but front/back specimen wetting is not required.
For technical buyers, the main commercial value is advanced exposure flexibility. The Xe-3-HDSCE combines three air-cooled xenon lamps, SOLAR EYE irradiance control, humidity control, BP or IBP plus CAT control, dual spray, chiller operation, AUTOCAL calibration and a large flat specimen tray. This supports repeatable, documented accelerated weathering and lightfastness testing for R and D, formulation comparison, supplier qualification, quality control and customer specification work.
