Save Time Specifying Ventilation Products with Greenheck’s eCAPS Engineer Application Suite

Greenheck’s free, online eCAPS Engineer Application Suite provides fast and easy selection of HVAC products including fans, gravity ventilators, louvers, dampers and Dedicated Outdoor Air Systems (DOAS) based on your application.

Select the right product for your building project. Just enter a few project requirements and let eCAPS quickly guide you through the selection process. eCAPS finds and ranks the best products based on cost and performance. Fine-tune your selection by indicating certifications or special requirements.

Compare models quickly and efficiently. Whether you want to compare performance, sound levels, operating costs or first costs, eCAPS puts that information for all applicable models on a single screen for easy comparison.

Reduce Errors. eCAPS automatically cautions when your selections are close to maximum fan rpm, close to being unstable, close to having water carry over (for louvers), or when enthalpy recovery ratio does not meet the minimum requirement.

Simulate installation performance. Use eCAPS’ System Effect Simulator to see how selected productswill perform under various inlet and outlet conditions.

Find more information in the eCAPS Toolbox. eCAPS’ convenient Toolbox features a damper selection guide, information on the latest product technology, and links to application articles and online fan courses.
