About WES

WES In Brief

We are a spin-off from IIT Madras, focusing on providing products which are pioneers in the segment of harnessing lost exergy, compressors and engines with superior power density and efficiency. We achieve this by going through innovation, design, development, and manufacturing practices to achieve the quality desired by ideation in-house. As a part of our endeavor to produce energy-efficient products, we are working on various sustainable ideas to improve industrial plant efficiency effectively and economically.   

Our Focused Products

Why Choose Us

Reasons For Industries Choosing Us

Quality Material

We use a dynamic volumetric control mechanism that controls the mass flow rate of admission steam to the expander. ​


This mechanism helps to achieve near-constant isentropic efficiency of the expander for the entire turndown. ​

Trained Workers

The peak load efficiency of the developed technology is better than the other available technology solutions.​

Time Availability

The power delivery of the Wankel expander is much higher for off-design conditions compared to the throttle-governed expanders, where the admission control is done by reducing the pressure of the admission steam.​

Quick Response

The lower number of parts, when compared to the reciprocating expander of similar size, could potentially increase the reliability.​

1 Year Warranty

The expander, as well as the canopy, is ergonomically designed by WES, considering safety and appeal to customers.​

Principles We Follow


The Sort step separates items in your workspace that you know you need from those that you do not need or may not need by moving the latter to a “red tag” holding area.


The Straighten step thoroughly organizes the items that remain after sorting, such that frequently used items are easy to access and every item has a clear and easy-to-find home.


The Shine step elevates the work area by thoroughly cleaning and inspecting tools, equipment, and other items. It also can include routine maintenance on equipment, which is one of the ways it flows directly into TPM.


The Standardize step is a bridge between the first three steps (Sort, Straighten, Shine) and the last step (Sustain). In this step, your goal is to capture best practices for 5S as standardized work for your team


The Sustain step assures that 5S is applied on an ongoing basis. It transforms your standardized 5S processes into regularly completed tasks.
