2. RENEWABLE ENERGY:               With the exposure of executing project jobs on SITC basis both in HVAC&R and Building industry we are now focused on venturing into the Hybrid Renewable Energy Power Generation in Solar and Wind energy catering to the range of 1kW to 10MW power mainly rooftops and off grid projects


We are ably supported by the founder directors and also Advisory board consisting of eminent people from the industry who have the expertise of teaching in premier Institutes like Indian Institute of Technology - Bombay and executing solar projects in India. We are also happy to be associated with kWatts Solutions Pvt Ltd, Mumbai, Dr. Chetan S. Solanki,-  Chairman for project drawings, supervisory implementations and validation of Hybrid energy power solutions.


Factory and R & D Lab: Seeing the huge potential in India for renewable energy for the next 25 years and with Industry growth currently clocking at 250 %  and the thrust from Central Government and each of the Indian State Governments fulfilling their energy needs who are quatripleting their budgets to meet their power demands. Seeing the tremendous potential, we intend to set up an ultramodern factory and a research Centre for the hybrid products to be manufactured in the factory mainly rooftop wind turbines.


We are in the process of acquiring 10 Acres of Land in most potential area for wind and solar energy in the state of Andhra Pradesh. With the support of the Local Government and able leadership of the Chief Minister Dr. Chandrababu Naidu, we cherish our dreams to lead in the lower segment of power requirement in the range of 1kW to 10MW power generation for self sustained building and institutions.

3.BUILDING MATERIALS & COATINGS:           To give thrust in Green Products we have entered into Franchise agreement with Hyderabad Industries Limited for Pre-fabricated Products for Pre-Engineered Building Materials and EXCEL COATINGS & NOVA SURFACE CARE for Sun Reflective Coatings for cool roofs and building also from DAIKIN Fluoro based ZEFFLE brand.

With the Green products and Services, namely Pre-fabricated Products  of HIL Limited of Hyderabad, under the banner of AEROCON who are pioneers and leaders in the field of Dry Wall Constructions and DAIKIN Fluoro chemical Division for their solar reflective coatings under the brand name of ZEFFLE thermal insulation coatings for cool roof and buildings.


Our new focus in green products in AirRef Engineer & Consultants, gives us imputes to further the LEED credit qualifications for Roofs and Buildings, Stopping Warm Earth, Decrease CO2, and Heat Islands.


The special pigment reflects infrared rays (changed to heat) in sunlight effectively to prevent thermal penetration into the building. Fluoro polymer has excellent durability and anti staining / soiling and keep thermal insulation performance.

AEROCON PANELS: Ideal for Partition Walls. 

Aerocon panel is the sandwich panel of two fiber-reinforced cement sheets enclosing a lightweight concrete core composed of Portland cement, binders and a mix of silicaceous and micaceous material aggregate.

These panels have a lightweight cellular structure, resulting in excellent thermal and sound insulation properties.

Aerocon panels are pre-cured. It is ready to install and does not need water or any on site preparation / mixing like other walling products. It is easy to work with and needs no special tools for installation.


·         Aerocon panels allow faster construction because of its tongue and groove joining system.

·         Aerocon panels’ water and termite resistant properties make an excellent choice for any land and climatic conditions.

·         Its low weight and Ductility makes an ideal choice for seismic and cyclone prone zones.

·         It also reduces the dead load on the structure.

·         It can be also dismantled and has high reusability.

·         It is also a “Green” product.

·         Aerocon Panel partition allows any kind of finishes including painting, wall paper, tiles, etc.,

Sun light -> Absorption

and change to Thermal energy / HEAT with constant heat on to the surface the surface temperature rises to a great extent depending on the surface material.


Therefore to reduce the room temperature the thermal insulation IR coatings are applied over deck.


Reduced Energy Cost: EXCEL CoolCoat ® topcoat remains white to effectively reflect the sun’s heat, unlike dark-colored roofs that retain heat and are subject to ultraviolet degradation. Roof temperatures can be reduced upto 20 degree C. Complies with ENERGY STAR® & Cool Roof Rating Council Guidelines. Ceritfied by "Building Energy Performance Laboratory", Gujarat.


Comparative thermal performance of EXCEL CoolCoat on corrugated roofing materials.

Temperatures recorded around 2.30 pm.

Thermal Test :

Ambient temperature = 40º C

Uncoated asbestos roofing = 56º C

Uncoated GI sheet roofing = 59º C

coated with EXCEL CoolCoat ® = 44º C

This result proves the continuous rejection of solar heat, preventing the roof from getting hot.

Note: The temperature indicated above is the exact temperature of asbestos roof sheets recorded with the aid of LASER GUIDED INFRARED NON CONTACT THERMOMETER


EXCEL CoolCoat® is a Single component, ready-to-use material available in various customized size packing. It may appear well mixed, but upon standing will settle into a two stage suspension. Thoroughly mix the contents of containers using a power mixer for a minimum of five minutes prior to application. Thinning or reducing the material is recommended as per the surface requirements.

Standard Packing Sizes : 4 lts, 10 lts, 20 lts and 50 lts
