Description

Sauermann Si-RM350 2-Way Digital Refrigeration Manifold

The Sauermann Si-RM350 2-Way Digital Refrigeration Manifold is used to commission and service all types of refrigeration-based installations, including heat pumps, air conditioning, refrigeration and reversible systems. It is suitable for domestic and complex industrial machines, combining the latest technology with intuitive operation along with a built-in smart digital assistant that helps technicians achieve their objectives in the best possible way.

The Si-RM350 supports over 130 refrigerants and features auto updates to stay aligned with evolving industry changes. It has a graphic display that is engineered for all lighting conditions, like being readable under direct sunlight, backlit for indoor use and an anti-glare design for great visibility. Technicians can rely on a long battery life of up to 300 hours, allowing for internal memory data logging at a capacity of 600,000 points or up to 9 days of recording. The Si-RM350 also includes 8 integrated programmes, such as efficiency calculations for COP and EER ratings.

 The new “Easy Mode” allows quick measurement with a single pressure port, while the innovative parrot clamp shape accommodates pipes from 6 to 42 mm. With an IP54 protection, the Si-RM350 is protected from dust and rain, making it suitable for demanding on-site conditions.

Probe Compatibility

The Si-RM350 works seamlessly with both wired and wireless probes at a distance range of up to 100 m/328 ft. For example, pressure can be measured via flexible hoses or the Si-RP4 probe, while temperature can be recorded using the Si-RT2 wired clamp, the Si-RT7 wireless clamp or the Si-RT5 self-gripping probe. Vacuum measurement is made possible via the Si-RV4 wireless vacuum probe, and for temperature and humidity monitoring, it integrates with the Si-TH4 wireless thermo-hygrometer.

Integration with the Sauermann Pilot app

The free Sauermann Pilot app, available on iOS and Android, pairs seamlessly with the Si-RM350 to provide technicians with complete control and reporting tools right from their mobile device. The capabilities include:

  • Real-time control and readings display
  • Secure recording of measurements
  • Create, sign and send reports with photos
  • Export reports in PDF or CSV (Excel) format
  • Manage a detailed customer database directly in the app

The Si-RM350 is built to be durable with features such as a high-strength aluminium hook for secure handling and housing constructed from polyamide reinforced with 30% glass fibre. Additional design details include an anti-theft padlock slot, a rear hook, and a modern USB-C power supply option. Plus, it is suitable for use with A2L and A3 refrigerants.
