NEED FORNEED FOR ENERGY CONSERVATIONENERGY CONSERVATION

Now the entire world is craving for new and long lasting energy resource.
Fossil fuel resources are fast depleting and may not last more than few
centuries, besides not being very eco friendly.
Generation of heating, refrigerating and air conditioning utilities typically
account for40 to 70% of the electrical power consumed in various domestic,
commercial and industrial sectors.
Meeting the peak demand of electricity with limited generation and
transmission infrastructure has been a challenge.

What is Heat Pump?What is Heat Pump?
Using the proven principles of refrigeration and air conditioning, heat from
the compressor and from air is used for heating the refrigerant gas.
Heated gas is compressed to super heat stage.
The total heat is then is transferred to the water storage tank through
patented coil.
The patented coils offers heat transfer with high efficiency, very lesspressure drop and no contamination of the water.
Heat pump technology has been used in air conditioning globally formore than 50 years and the technology is well proven.
The MWE Multi Utility Heat Pump, is at the leading edge in terms of
longevity and efficiency in all weather conditions.

Radiant Cooling SystemRadiant Cooling System
A radiant cooling system utilizes large surfaces, such as the floor, wall or ceiling.
Rooms are cooled by circulating water through embedded plastic tubes, excess
heat being absorbed by the surface.
Air change rates can be reduced to a minimum.
Radiant cooling system components can also be concealed, which enhances
the architectural concept and improves the rooms aesthetics.
Similarly to radiant heating, the temperature of the water circulating in the pipes
and room temperature are always close to one another, creating gentle,
comfortable cooling.
Cooling energy consumption is reduced, a key factor in obtaining moderate
energy bills.
It is a genuine benefit of the system that it allows you to install both heating and
cooling based on a single system16

DeDe--HumidificationHumidification
As one more value added by-product of the main system is
dehumidification.
Dehumidification is required due to geographical location.
With MWE Dehumidification the system can control the humidity
level between 50Rh to 60Rh.
Dehumidified air can be circulated by blowers through existing
ventilation system. With the use of dehumidified, air conditioner load can be reduced
and average temperature can be maintained at 27C.

To have maintenance free system as option we recommend to
install water descaling equipment.
This will reduce maintenance and increase the useful life of the
complete system.

Revenue generated through recovered heat can more thanpay for the cost of operating the cold utility generators!
Increasing energy costs and raising concern forenvironmentheightens the need to go for heat recovery systems.
Installations have been working satisfactorily for several years,in many cases without a service call.
Co-production of multiple utilities using a single system helpsreducing space requirement, initial cost and maintenance.
CO2 emissions are also reduced and electrical demand
reductions are also realized. Proper application engineeringcan ensure a Win-Win situation of simultaneously reducinginitial and operating cost.
