We believe it is important to maintain a long term partnership with our customers. Naturally, we provide all the technical expertise on installation and applications support which may be required to initially commission our equipment. But beyond that, our customers can be confident that we will continue to give ongoing service and support in the future. Our products are designed to be expandable. While a system configuration may match initial needs and budget, our equipment can subsequently be expanded to handle future growth. So the investment in existing critical system support equipment is not lost as soon as our customers expand their operation.
