Projects and Case Studies

A key component of the MultiGen system is the MultiChill Chiller developed by Cooltec in the USA that now forms part of the MultiChill Technologies MultiGen System. The following are some of the projects CTI and WES were involved in as the product was developed. There follow a series of specific operating experience examples including some Client quotations.

The MultiChill 5 RT unit demonstrably meets or exceeds its performance specification, operates reliably and with low maintenance requirements and works in an exhaust heated CCHP environment. Details are also given of independent performance checks to verify that specified outputs are achieved.
