Lessons learned |
|
| |
| Initiative |
M/s Parle Products is a known name and actively involved in ensuring highest quality standards for Environment Management Systems, Occupational Health and Food Quality. The company while utilizing Thermic Fluid System for preparation of Sugar Syrup identified the areas where major energy consumption was taking place. After thorough brainstorming and energy analysis they identified the required heat and potential for HSD savings. This triggered use of SWH System. The management had worked out the relative cost of sugar syrup preparation, vis-a-vis the existing thermic fluid system and thus implemented the SWH System.
|
|
| Integration methodology |
The R.O water pumped up to the collectors on the roof top, where the water is heated to the desired temperature. This cold water is pumped up to the ETC assembly the system using a pump. The SWH system works as thermo-syphon.
