Adjusting refrigeration systems
The advent of digital technology means huge quality improvements when it comes to the adjustment of refrigeration systems or heat pumps.
Digital manifolds provide high-precision temperature and pressure measurements, determine subcooling and superheating, but also enable reliable evacuation of the system through accurate vacuum measurement.
And the convenient testo refrigeration App makes commissioning, maintenance or repair even quicker!
