The Situation

The Prasad Group was established in 1967. In 1996 a joint venture Prasad GWK Cooltech Pvt. Ltd. was formed as a co-operation between Prasad and Gesellschaft Warm Kaltetechnik mbH of Germany.

Gesellschaft Warm Kaltetechnik, GWK, has for more than twenty years been manufacturing world-class energy-efficient compact chillers and mould temperature controllers mainly aimed at the plastics industry. Prasad GWK Cooltech Pvt. Ltd. was established in order to combine the GWK know-how with the Prasad Group’s very strong position in the Indian and South East Asian markets.

GWK knows Grundfos from its activities in Europe, and it was natural, therefore, to choose Grundfos as the supplier of pumps for Prasad GWK Cooltech’s production of compact chillers and centralised chilling plants.

The Grundfos Solution

 The Grundfos CM range of multistage centrifugal pumps offers a very compact design that make the pumps easy to fit even where space is limited. It is a robust design with a leakage-free mechanical shaft seal and stainless steel hydraulic parts. As an option, the pumps can be supplied in all-stainless versions.

The Grundfos CM pumps offer noiseless operation, low energy consumption, and easy low-cost maintenance – which is exactly what Prasad GWK Cooltech was looking for their high-quality chiller plant

The Outcome

With the Grundfos CM pumps, Prasad GWK Cooltech is able to offer a line of products that fully live up to the very strict quality standards that are a hallmark of the Prasad Group as well as of German GWK. The result is trouble-free, energy-friendly, and noiseless operation with no unscheduled service stops.
