Problem Addressed

Companies use high man power to gain asset understanding and to find ways to improve carbon footprints. Plexus Innovation’s GUARDIAN® helps companies overcome challenges including data overload and compliance and helps them on the road to Net-Zero. GUARDIAN® reduces water waste, unnecessary energy use and the need for vehicles on the road in certain scenarios due to the IoT’s remote nature, which consistently uncovers new and innovative ways to be environmentally sustainable.

Solution Overview

Plexus Innovation offers an IoT remote monitoring solution – providing a digital alternative to manual measurement, bringing business improvements in a number of sectors.

The company’s GUARDIAN® technology remotely measures temperature, pulses, humidity, and CO2, allowing you to manage water systems, cold chain storage and refrigeration; along with air quality, and damp and mould detection.

Many customers are using GUARDIAN® to tackle reducing their water waste, some saving up to 80% within months of installation. Others are focusing on reduction of energy consumption, or on ensuring compliance on environmental health and risk for tenants.

The remote technology is attracting clients focused on Net Zero and business improvements including better use of manpower and delivering improved service to their own customers.

It is an innovative proprietary product that addresses legislative issues, pushing compliance and asset management into the 21st Century.

A typical time scale for ROI is within 12 months. For those who are challenged with reducing risk of human error, operational costs, water waste, energy consumption or environmental impact, GUARDIAN® is now a must-have technology.

Case Study

Selwood Housing was finding the traditional manual approach for monthly temperature checks cumbersome and administration heavy, using high manpower to gain limited asset understanding. On switching to GUARDIAN® the phase one results were immediate:

  • 75% reduction in flushing requirement and associated water waste
  • Numerous potential scald risks, due to failing TMVs, identified via alerts received

When implemented across phase two, a further 21 facilities, the results included saving:

  • 28 days of manpower
  • 11 tonnes of associated CO2 (equivalent to 66 trees)
  • 240m3 water (3200 domestic baths)
  • 4900 kWh energy

The data gives them a better understanding of their TMV performance and whether there is a scalding risk enabling them to take relevant action.
