Benefits of Using RODEM® in a Crisis

The future of Chiller Service Support is Remote Access

Since RODEM® was first launched in 2014 we have now established remote access upon Chillers at sites across the UK.

The current Coronavirus crisis has seen the RODEM® system come into its own. Despite many clients effectively shutting their doors, we retain full-service access to RODEM® equipped Chillers across our portfolio of sites.

RODEM® is at the cutting edge of Machine to Machine (M2M) Internet technology, and only now are reliable, industrial grade, interactive 3G / 4G routers becoming available to the market. The latest feature external alert capability.

So we are no longer reliant upon the client notifying us of a problem, or discovering this at a routine remote service check, “RODEM® 2” alerts us to any machine going into fault via email, so we know within a few seconds of a site issue, allowing us to be proactive in assessing what’s up. We even get a follow-up email when a fault clears.

RODEM® has also proven that in a considerable majority of fault situations we can resolve the immediate issue remotely, with further site attendance simply not necessary, or where minor background issues can be dealt with at a future routine site physical visit.

After ~6 years of service, RODEM® has eliminated ~85% of physical site attendance to breakdown related call-outs, a response is generally ~15 minutes from first call or auto email alert. For most clients, physical servicing costs have reduced by up to 50%, and when the peripheral benefits are considered, RODEM® is entirely self-funding with a surplus from reduced revenue costs (energy savings from optimisation and increased uptime).

Response to a problem is rapid however we also routinely log on to the Chillers at least once each month to observe any issues and apply minor seasonal adjustments.

For each service visit, a detailed report is issued to the client.

Training with RODEM®

Our training sessions utilise our Chiller simulator to allow our staff to interact with the system and better understand how changes in a Chiller's operation can be observed and acted upon using RODEM®.

They can also learn how to assess a Chiller, and apply adjustments.

Training then extends to observations and adjustments of live Chillers via live RODEM® units.
