The company was founded over 30 years ago operating primarily in
the petro-chemical and mining industries in the design of
electronic control systems, the manufacture of which is still a
vital part of the company's business.
Specialist in the
Control of Electrical Energy
From this background it was a natural progression into energy
saving products and systems to satisfy the needs of these clients.
The particular focus has been on electricity usage as this is the
most expensive form of energy and a field where the company has
had a long experience and expertise. It is also important for
environmental reasons to control electricity consumption as the
quantities of greenhouse gases responsible for global warming
produced by the fossil fuel burning power stations are far in
excess of that produced by other forms of energy use.
DEM Metron products
and systems for energy control of lighting and electric heating
have been developed largely from operational research dedicated to
applying the most appropriate form of electronic control to meet
the particular needs of different types of buildings and different
types of users.
DEM products are
compatible with all types of lighting for retrofit or new build
applications and can be installed with the minimum of modification
to new designs or existing wiring schemes. Furthermore, no
specialist knowledge or training is required on the part of the
installer or the end user.
The fact that electricity is so much more expensive than other
forms of energy means that measures to reduce its usage on lighting and electric space heating can result in a payback of the
capital cost in a relatively short period of time.
In many buildings the
total electrical energy used for lighting is often only 15% of the
total energy provided by the gas or oil to heat the building,
however, the electricity bill can often be more than 40% of the
total energy cost.
The relatively low
cost of electronic controls, which can be easily and quickly
applied, is a significant factor in making energy controls for
lighting and electric heating a first class financial proposition.
