Industrial Ventilation & Pressurization: |
|
| |
Large Industries need ventilation systems for fresh air along with pressurization to stop infiltration of dust inside the factories. This improves the product quality and the efficiency of the workers and machines. |

Industrial Evaporative Cooling |
|
| |
For Industries to have well working conditions for workers to increase productivity and decrease absenteeism. This is an ideal and most economical system which brings down the inside temperature by 8 to 10 deg C and inducts 100% Fresh air. The power and water consumption are quite low when compared with Air Conditioning systems including the initial installation cost |

Direct Indirect Cooling: |
|
| |
The latest in series for working in Dry and Humid conditions with optimum power and water requirement. This system is replacing conventional Air Conditioning systems worldwide. It can achieve saturation efficiency of more than 110%. In this first the air is sensibly cooled and later on adiabatically. |

Natural Ventilation
This system requires no power as it works on the principal of natural inlet using wind velocity and natural exhaust using temperature stack effect and Bernoulli's principals. This is majorly used in the Industries generating large sensible load.
Multi-Stage Filtration
The Industries that requires clean fresh air for manufacturing of high quality products require such systems. These systems are designed with multiple filters of various filtration levels for easy maintenance at reduced initial and running cost
Industrial Exhaust
These systems are required in the Industries involved in Heavy engineering works where large amount of fumes or dust is generated. The systems can be designed to take out the exhaust from localized areas and the exhaust air can either be induced inside the factory after cleaning as per norms or thrown out o the atmosphere.
Kitchen Ventilation
The kitchen is the most important area where all the cooking is taking place. It needs the proper ventilation system to ensure the cooks comfort with cleanliness and exhausting out the fumes generated while cooking. This systems includes supply and exhaust equipment with proper balancing of air to ensure the best performance.
Basement Ventilation
This is mandatory as per government law for comfort and Fire issues. Various type of systems are available for this depending on the requirements.
Cogenration
Need of the hour is to have cogeneration systems where in any form of energy which is going waist is utilized in another form. This will maintain the energy balance of the systems thereby saving substantial cost.
Clean Air
Electronic and Pharma Industries demands for comfortable and clean climate as per regulations to maintain the quality of the products. The various classes of cleanliness can be achieved by installing the right equipment.
Spot Cooling
Industries having large areas with few workers and large machines needing comfortable condition for worker's and some ventilation can be catered by designing spot cooling system. This is the only cost effective system with respect to initial and running cost. It is widely used in such Industries.
Diluation Ventilation
Large heavy Industries generated fumes and dust and the possibility of localized exhaust is low, the dilution Ventilation is the only solution to such needs. The system is designed wherein the Fresh filtered air is inducted in to the area which then mixes with the inside air and then exhausted out.
Power House Ventilation
Powerhouses generate lot of Heat, which affects the performance of the equipment. Ventilation system can easily remove the large portion of heat thereby making the equipment perform better as well as efficiently.
Cooling Schools:
The demand of fresh filtered cooled air in the classrooms and assembly halls is increasing due to high pollution levels in the school vicinity including the bad weather conditions in summer and monsoon. By providing the evaporative cooling system, these conditions can be achieved with optimal running and installed cost.
DG Room Ventilation:
The performance of any DG is based on the intake air and surrounding temperatures as well as the quality of fresh air. By providing either fresh air supply system or evaporative cooled air systems, the performance and the efficiency of these systems can enhanced.
Gas Trubines Intake Cooling:
The efficiency of any Gas turbine is directly proportional to the mass as well as the temperature of intake air. By installing the evaporative cooling system where direct air and water contact is taking place, the mass of intake air is increased and temperature is reduced, results in higher output at the given ambient conditions. The initial cost of evaporative cooling system is low, the pay back period is small.
Muti Stage Cooling:
This equipment can work during all the three seasons with the best performance and save large amount of power and water. In summers it works on 100% fresh air on direct indirect cooling system. In monsoon, it works with chiller with return air. While in winters, either hot water is used on the inside heat is used by recirculating the air. This system has to be installed based on the special requirements.
Industrial Process Air Conditioning:
The demands for process cooling are specifically for the performance of the equipment only where either the controlled temperature water or air is to be done. Various technologies, systems and equipment are available to get the desirable conditions.
Industrial Air Conditioning:
The Industries where the controlled temperature and humidity are critical for machines, requires special Air conditioning systems which can perform with the best efficiency at minimal costs.
Roof Cooling:
The maximum cooling load in any large or medium Industry for enclosed area being conditioned comes form the roof through conduction, convection and radiation. The roof cooling by installing special type of water cooling sprinkling system can reduce this load to zero, thereby saving the power and running cost with minimal investment with good payback period.
