Services
At AIROCHEM, We manufacture Centrifugal Fans, Axial Flow Fans, Air Pollution Control Equipments, Execute projects on Trunkey Projects. Other than this we also provide following services.
- Retrofitting
Initially the fan is designed on safe side for the success of installation. In actual scenario for continuous rating flow and pressure requirement is much less than design condition.
Let us take an example of bio fuel fired boiler. Initially, boiler fan capacities are designed for 35% excess air, and further margins of 25% above these quantities are kept for safety. Generally this results in fan operating at a point away from best efficiency point. This causes loss of energy, and waste of power.
To avoid such a situation, we can adjust the fan by suitably modifying design to move operating point in high efficiency zone. We have done such jobs and benefitted clients by enhancing capacities with power saving.
- Wear Resistance Solutions
To enhance the life of impeller by providing proper hard facing solution is our specialty. At JK Sugar in Utter Pradesh, the ID Fan impeller was wearing out every 15 to 20 days. It was found that the fuel contained more silica. We decided to use backward inclined straight blades in place of curved blades, and used special alloy hard facing process, resulting in enhancing life of impeller to 6 months. The necessary retrofitting was done.
- Field Testing of Fans and Systems
We have portable field testing instrument for testing fan performance at site. It has three manometers with least count upto 0.01mm in inclined position. It also has barometer, static pitot tube for measuring velocity pressures. This helps diagnosing faults in process and set it right.
- Field Balancing and Vibration Analysis
We have SKF field balancing and vibration analyzer, and we provide services on this side.
> - Shaft Alignment
Shaft alignment services are provided using laser alignment tool
