    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

    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.

    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.
