Hi Sreeranga,
I do not believe they offer a trail version to download, please contact your Qlik vendor or e-mail Qlikmaps with your contact details, including your phone number, they will get in touch with you, one of their account representatives will contact you to talk about your needs, before they organize a presentation at their office or your own office. Their response time is acceptable, they took a couple of days to contact me.
Good Luck, it is a good product.
