Combined Heat & Power (CHP) Plants


A Combined Heat & Power (CHP) plant can take many forms. In essence however, it consists of an electrical generator combined with equipment for recovering and using the waste heat produced by that generator. CHP schemes have a multiple of well-documented benefits.

Remote Asset Monitoring 


Where energy is being generated at remote locations from diesel-powered generators, it is critical that electricity is constantly available to the equipment and/or people who rely on such a source.  Failure of electricity supply in these instances can result in serious consequential disruption to the connected remote processes, such as mobile telephone transmission towers. To ensure efficient and reliable delivery of these services, there has to be enough diesel fuel in the tank and the genset status must be correct.  Rapid detection and reaction to an unusual reduction in fuel tank levels, a genset malfunction or an unexpected increase in electricity consumption would, therefore, be essential.


Energy Sub-metering


The global reach of Dexdyne’s technology now includes Nigeria with the recent implementation of a project in the Energy Sub-metering sector to a multinational energy consultant. 
This project involves monitoring over 20 power meters, geographically dispersed over a large site, with the aim of logging each meter’s maximum power consumption over one-minute intervals in order to profile peak demand.  The acquired  data is sent to a central server where it is analysed and processed to show the peak power demand for each area of the site.  

Knowing when peak demand occurs means that existing generator capacity can be used more effectively, leading to a reduction in the site’s peak power demand.  This helps to reduce requirements for additional generating capacity and thus saves a significant amount of money from the plant’s capital expenditure budget.

Gas Monitoring


Underground gas monitoring presents its own unique set of challenges. This applies particularly to sites that rely on methane drainage to supplement traditional fan-based ventilation systems.  However, monitoring these vents can prove difficult, as they are often located in areas without an electrical power source nearby and as such may not be monitored regularly. Commonly, the first evidence that a methane drainage system may not be operating efficiently (or not operating at all) can be an increase in methane concentrations at a return air shaft - or worse - underground where the workforce is exposed to the risk of a methane explosion.

Environmental Monitoring


Dexdyne’s web-enabled monitoring system is used around the world in many vertical markets such as energy generation and sub-metering, water and sewerage treatment works, gas extraction plants, pumping stations and CDM projects.  Now our technology has found a new application - air quality monitoring.
Our web-enabled Remote Communications Terminal (RCT) can accurately log dust particle counts, wind speed, wind direction and ambient temperature.  The data is then sent to our Cloud server over a GPRS/3G/4G network and can be simply accessed by authorised personnel over the internet.  Our system is user-friendly and intuitive.  The user can  easily configure logging intervals and SMS threshold settings on key parameters.  Dexdyne’s technology can be used to graphically analyse large amounts of collected data from multiple parameters.  Critical business data can then be either automatically delivered as regular reports by email or manually downloaded in Excel format.

Energy Management


For good financial and environmental reasons, management of utilities - and energy in particular - is a matter of serious concern to many industrial, public and retail organisations. 
To achieve optimum savings while meeting environmental forecasts, it is first of all necessary to visualise actual consumption patterns and trends before attempting to manage energy objectives.

CRC Compliance Monitoring


The CRC Energy Efficiency Scheme is a UK Government scheme designed to improve energy efficiency and cut carbon dioxide (CO 2 ) emissions in private and public sector organisations that are high users of energy.  
CRC operates in phases:  Phase 1 ran from April 2010 until the end of March 2014; we are now in Phase 2 that runs from 1 April 2014 to 31 March 2019. This scheme affects any organization whose half-hourly metered consumption of electricity is 6000MWh.

Air Conditioning & Refrigeration


Air-conditioning, refrigeration or climate-controlled environments are part of our daily lives in the workplace as well as in recreational and public domains.  In many commercial or public places, these facilities can constitute the single biggest user of energy. 
At a time when energy tariffs are ever increasing, this can represent a substantial cost.  Your challenge will be to keep systems running and costs under control. Inefficient or malfunctioning AC&R equipment may result in expensive bills, discomfort and inconvenience to customers.  In the case of climate-controlled environments, it may result in a serious loss of assets or even danger to health and well-being.
