The electrostatically applied polyester epoxy powder-based coating is cured at high temperature and is so durable that these models are backed by the best warranty in the industry.Įnergy Efficient. Hot-dipped galvanized steel, welded for maximum strength is combined with our exclusive POLYBOND® fi nish that protects the whole system – cabinet pans, distributor covers, louvers, and all other parts contacting water. This basic principle underlies the design of the MasterCool direct evaporative cooler. Put simply, whenever water is evaporated, heat is absorbed.

In the next cooling stage, this air is further cooled along a new wet-bulb line (B to C), resulting in a lower dry-bulb temperature of leaving air than can be achieved with single stage direct evaporative cooling alone.ĭIMENSIONS AND SPECIFICATIONS Single Inlet Model Dimensions MD524 or UD960 (Down Discharge) and MS524 or US960 (Side Discharge) Top View Side View Front View MD/MS524 or UD/US960 Media SectionCabinet Model Number 1 Required H W Drain1 Location Duct Location Side D A DM080 or UM080 51½ 491/8 66 DM120 or UM120 51½ 491/8 70 Down C E B F G Media Blower Cabi- Cabinet net J K Water2 Service Location L M Electric3 Service Location S T Dia. The result is a dry-bulb temperature of the leaving air (B) approaching the wet-bulb temperature of the entering air (A).Ģ-STAGE INDUSTRIAL EVAPORATIVE COOLING Indirect/Direct Evaporative Cooling Process The Indirect Cooling Module In the indirect cooling stage, entering air is cooled along a horizontal humidity ratio line on the Psychrometric Chart (A to B) without adding moisture. SINGLE-STAGE INDUSTRIAL EVAPORATIVE COOLING Direct Evaporative Cooling Process MasterCool Evaporative Media Direct evaporative cooling exchanges sensible heat for latent heat, and follows upward along a constant wet-bulb temperature line on the Psychrometric Chart.
