Improved boiler room efficiency leads to: Fuel Savings – typically in range of 5-25% Reduced Carbon Dioxide Emissions Typical paybacks between 6 months and 2 years

Proven technology with numerous successful case studies from the UK & USA, and recently in Australia

Over 10,000 units installed worldwide

CCM is an authorised distributor for Australia – new technology for this market

Boiler Load Optimisation

Boiler Optimisation

Boiler Load Optimisation Specifically designed to overcome the inherent problems of excessive cycling

Retrofitted onto existing boilers with no impacts to building temperatures or existing control strategies

Integrates with and complements existing boiler controls (e.g. Building Management System, sequencing, Outdoor Temperature Compensation)

Uses flow and return temperature sensors and proprietary software to regulate boiler cycling

Prevents boilers cycling on to recover standing losses; only respond to genuine calls for heat

Is widely overlooked – leaving untapped energy savings

Red sections show sporadic firing periods of <15 minutes

Pink sections show boiler firing continuously

Initial Site Analysis

Sabien- How Does it Work? Flow and return temperatures are analysed independently every 10 seconds by two digital probes (measuring every second) Intelligent and self adapting software monitors the boiler’s thermodynamic profile in real time Boiler temperature decay is monitored to distinguish dry cycling from genuine calls for heat

Should the temperature decay be more rapid from the boiler’s set point - this will indicate a genuine call for heat from the building load, rather than just standing losses

Boiler Temperature

The M2G measures a reference point of the flow and return temperatures when the boiler reaches the required set point and creates 2 temperature gradients The M2G measures the temperature decay of the flow and return every second to identify the true load profile of the individual boiler The M2G will prevent the boiler from firing due to dry cycling, i.e. within the deadband values.

Identifying a Genuine Call for Heat If the flow or return temperature decay is outside of the deadband values, the M2G allows the boiler to fire to meet with the genuine heating demand The M2G re-calculates these values each time the boiler reaches the required variable set point temperature This ensures the required ambient temperatures and hot water within the building are not compromised

Individual Boiler Analysis Dry cycling cannot be identified by measuring the blended temperatures of all the boilers connected into a common header- this must be identified at each boiler
