Leak testing for heat pumps, refrigeration systems, and refrigerant circuits
HVAC, heat pump, and refrigeration systems must operate efficiently, safely, and with low emissions over long periods. Leak-tightness is a decisive quality factor: even small leaks can cause refrigerant loss, efficiency drops, environmental impact, or functional malfunctions.
MACEAS develops testing systems for components and assemblies in refrigeration, air conditioning, and heat pump applications. The systems can be designed for individual components, pre-assembled modules, or complete circuits—depending on test pressure, medium, component volume, leakage rate, and production process.
Leak testing in HVAC, Heat Pumps & Refrigeration
Typical components in heat pumps and refrigeration systems include compressors, evaporators, condensers, heat exchangers, pipelines, valves, accumulators, brazed joints, welded connections, and service ports. Especially with modern refrigerants and high efficiency requirements, reliable leak testing in production is indispensable.
Depending on the application, helium, forming gas, or other suitable tracer gases can be used. In addition to integral leak testing, precise leak localization is also important to quickly identify defects at brazed, welded, or joined points.
Application examples
- Helium leak testing of heat exchangers
- Sniffer testing on brazed and welded connections
- Leak testing of compressors, valves, and connections
- End-of-line testing of pre-assembled refrigerant modules
- Testing concepts for natural and synthetic refrigerant applications
