2 UL TRA MODULE ULTRA MODULE Comprehensive Evaporative Cooling Solutions At the Pahwa Group, continuous Innovation is the driving philosophy. The focus is on Technologies which benefits you, our customers and partners in progress. The group employs over 400+ people in 6 continents and has state-of-the art manufacturing facilities, including 8 best in its class Test labs. We have filled patents globally in the last 7 years ( many granted). Operating within a board framework of 'energy and environment', the group comprises of 4 knowledge based technology driven airgineering companies specializing in technologies, products & services with desiccants at the core, in relation to air. Bry-Air and DRI are the two flag ship companies of the group. DRI is a global provider of components & systems for Energy Recovery, Indoor Air Quality (IAQ), Fresh Air Treatment, Evaporative Cooling, Desiccant Dehumidification, and Green Buildings. DRI's Evaporative Cooling Range is available under the brand. What is Evaporative Cooling? Evaporative Cooling is the process of reduction in temperature of air through the evaporation of water. As water is evaporated sensible energy is lost from the air thereby reducing its dry bulb temperature. Warm Outside air is taken into the unit through wet EcoCool Cooling Pads. The cool humidified air is supplied. Outdoor Air Hot & Dry How does Evaporative Cooling Works? Water Cool & Fresh Air SYSTEMS COMPONENTS Evaporative Cooling Pads (ECPs) Free Flow (Spot) Hot Fresh Air TM Fire Retardant Pads (FRPs) Cool Ducted/Direct CNC Manufactured Compact Module Evaporative Cooling Modules (ECMs) MODULE Indirect Evaporative (IDEC) TM Evaporative Cooling Pads Adiabatic Cooling Dew Point Desiccant Desiccant Rotor Solar-Assisted Desiccant

The air is filtered of dust/allergens. Working air removes heat. Heat and moisture is exhausted from the systems. Cool product air enters the building with no added humidity. 6 Outlet Condition with Dew Point Cooler Supply with DEC Outdoor Air HUMIDITY RATIO - GRAINS OF MOISTURE PER POUND OF DRY AIR The working air initially enters dry channels where it is pre-cooled sensibly before it is fractioned into multiple streams which are directed into wet channels. The heat from the product air is transferred to the working air in the wet channels by means of evaporation. The heat is exhausted out the sides of the DRI Cool ULTRA Module and then to the atmosphere. The product air stream is completely separate from the working air and never comes in contact with a wetted surface. This process occurs multiple times in a short physical space within the exchanger, resulting in progressively colder product and working air temperatures. This system is modular, so the size and shape of an Air Handling Unit can be changed to meet user requirements.
