Page 5: Basic Information
Basic Information View and Options The views of standard NG series dry coolers’ product line are shown on Pic.C.1. and C.2 below. Dry cooler Options • Capacity. NG series dry coolers range broadly in their capacities, which depends on factors including physical size, fluid flow rate, glycol concentration and ambient conditions. - Page 6 • Pump package (optional). As needed, dry cooler could be equipped with pump package – to establish cooling media flow (or to serve as additional/booster pump). For multi-fans coolers: If pump • package is required, each “two-fan” • section, normally, would get its own package (Pic.

Page 13: Basic Maintenance
Basic Maintenance Although dry cooler is built for minimal service downtime, periodic preventative maintenance is required to ensure maximum reliability, safety, and operating efficiency. WARNING! To ensure equipment longevity and proper and efficient operation, it must be maintained properly. It is recommended to create a facility-specific Routine Maintenance Program. Failure to perform necessary maintenance task(s) properly and regularly could result in personal injury, equipment damage or malfunction and will void the equipment warranty. -
