NESPAL (formerly NESPL) was founded by Anup Nalamwar (B.E. Mech) under the guidance of Mr. Prakash Nalamwar (Ex-servicemen-IAF, DME & DEE) in 2003.
Having worked in IAF, Mr. Prakash has instilled the great virtues of Defence Services viz., Commitment, Dedication, Team Work, Quality, Transparency, Trustworthiness and Care
Anup Nalamwar (BE Mech) is having 16+ yrs experience in Mktg, Designing and Business Devpt. He is aptly supported by:
Ravi Aghao (B.Tech. Mech) is looking after Application Engg to develop newer applications. Anup & Ravi are from Government College of Engineering, Amravati.
Vitthal Wadhekar is looking after Installation, Commissioning and After Sales Service. Though Vitthal is an ITI (RAC), he is capable of getting the Repeat Orders just by an excellent service.
We have technical tie-up with one Engineering Consultancy firm having more than 20 engineers, having total 100 years+ experience.
What is “Air Water Heater”? Like Solar Water Heater works on Sunlight, Air Water Heater works with environmental/atmospheric AIR independently on sunlight. “It is an instrument/concept where the heat from atmospheric air is absorbed, and is transferred to water through the mechanism for water heating using thermodynamic principle, saving up to 80% energy.” or “ It is an instrument which absorbs the heat from atmospheric air and transfers to water through the mechanism for water heating using thermodynamic principle, saving up to 80% energy.” Air Water Heater can extract heat even from Himalayan air i.e. sub-zero temp (up to -30 oC.).
Air Water Heater can be divided in to 4 sections: 1. Evaporation – to absorb atmospheric latent heat/energy 2. Compression – to raise the pressure and temperature of
energy rich vapours 3. Condensation – to release the energy in water and
increase water temperature up to desired temperature 4. Expansion – to convert heating fluid in to ideal cold
fluid Let us see working of each section in next slides:
In a heat exchanger (evaporator) the liquid cooling media draws energy from a heat source, in this case from ambient air and expands with increasing temperature.
In a compressor, under the supply of electrical energy, the now gas form (warm) heating fluid will be compressed and heated additionally. The heating fluid leaves the compressor as a very hot gas.
Plusses of Air Water Heater Micro-processor* based control Connectivity* with Aurangabad based server for online monitoring
(under implementation) and data logger Suitable for hard water of any hardness due to in-house developed
heat exchanger System auto cut-off due to any component failure Independent LED’s for individual component & control Possibility of installing Monitoring panel anywhere in the building
(advantageous as system is installed at terrace) Up to 100% hot water availability with Dual Tank Design Low heat losses from hot water tank as the insulation is decided
based on the particular climatic conditions System comes with Fully Charged with Heating Fluid (gas) and no
charging at Site. Can be commissioned in few hours * in higher capacities
Adaptability with Existing / New Building Very Compact – 40000 LPD system – 8’ x 5’ x 5’ Less weight – 40000 LPD system – 750 kg With Dual Tank design, weight of water/tank can be distributed in
larger areas (the minimum height of tank is just 1.5’ for any size – pl ask us for write up of Tank selection)
Due to low height of tank, aesthetics of the building elevation is maintained
End user Cold and Hot Water Connections for any tank capacity can be customised, from ½” to any desired diameter
Power connection up to 60 flat building required is 1 phase and for above, 3 phase, maximum connecting load (for 40000 LPD system) is 27 kWh, 3 phase
Can provide hot water return line without affecting the hot water availability, thus saving precious water and get the benefit of providing hot water always at tap to your patrons
Availability of Terrace / Open Space due to compactness Low cost in Electrical infrastructure – for 60 flat building with
2 nos, 2 kW geyser per flat, connected load is 240 kW whereas equivalent AWH connecting load is JUST 8 kW
Due to return line, metering of hot water is possible and accordingly the individual user can be charged, thus overcoming the unforeseeable arguments
Due to low energy bill and round the clock hot water availability, the users will be happy and in turn the Developer will be benefited for providing the most economical hot water solution
Testing Facilities We have in-house Testing facility – Environmental Test
Chamber comprising Insulated Chamber, Air Conditioner, Heater, Water Chiller, Hot Water Tank, and all Controls.
We can measure 42 Parameters while testing We can create here the site atmosphere from 1 to 55 oC Along with atmospheric conditions, we do have facility for
producing cold water as per site condition Each and every machines is tested as per site condition for
worst, lower and higher ambient and water temperature
