Iso 9001 Gas Heating Furnace Testing Equipment 40kw Thermal Efficiency ±1%

Product Introduction

• Power adaptability: 0-40kW, suitable for wall-mounted boilers (18-30kW), floor-standing heating furnaces (30-40kW), supports natural gas (12T/10T), liquefied gas (20Y) full gas source testing, simulating combustion stability under different air pressure environments (500-3500Pa).
• Environmental simulation: water temperature adjustment 5-95℃ (accuracy ±0.5℃), room temperature 5-45℃, with water hardness simulation (0-1000ppm), verify the anti-scaling ability of the heating furnace under complex working conditions.
• Thermal performance: thermal efficiency test (dual thermocouple method, accuracy ±1%), load adjustment ratio (maximum/minimum heat input ≥3:1), flue gas composition analysis (CO≤300ppm, NOx≤50ppm).
• Heating water/domestic hot water dual circuit detection: heating water flow rate 0-30L/min (accuracy 1%), bathroom water flow rate 0-20L/min (accuracy 0.5%), adapted to GB 25034 Clause 6.5.1 dual-circuit test requirements.
• Safety performance: air tightness detection (1.5 times the working pressure for 15min, leakage ≤0.01L/h), gas valve response time (open/close ≤50ms), overheating protection (95℃ automatic shutdown).
• Electrical safety: ground resistance ≤0.1Ω, insulation withstand voltage 1800Vdc/1min, in line with EN 61326-1 electromagnetic compatibility requirements.
• Operation interface: 12-inch industrial-grade touch screen (Chinese and English switch) with built-in 8 major test templates (such as CE certification full items, Energy Star energy efficiency test), one-click start process, parameter setting time shortened by 50%.
• Data management: 128G solid-state hard drive automatically generates PDF reports (including SPC control charts and energy efficiency rating determination), supports USB/Ethernet export and MES system docking, and the data traceability period is up to 10 years.
• Quick clamping: The pneumatic quick-release clamp completes the DN20-DN50 interface replacement within 5 minutes, and is compatible with wall-mounted/floor-standing heating furnaces of brands such as Navien and Vaillant.
• Multi-station parallel: Standard 6-station independent testing (optional 12-station), detection efficiency increased by 80%, supporting full inspection/sampling inspection requirements for production lines with an annual output of more than 100,000 units.
