Air is a mixture of moisture and air. Hence this moisture needed to be removed from the air by changing the temperature and humidity through a medium. The process in which the moisture is removed from the air is called Dehumidification process. This functionality could be achieved by using Appidi Dehumidifiers. midifier shall be Honeycomb Desiccant type and the patented refined technology which goes into manufacturing of Desiccant Rotors is most reliable and energy efficient. As a result our rotors will regenerate to its optimum level with only 120 Deg C. In several cases our Dehumidifiers are working with only low pressure steam of 3.2 Kg / Cm2 without adding any backup heaters. Our Dehumidifiers are so efficient that they maintain as low as 12% Relative Humidity with only 85 Deg C regeneration temperatures in favorable weather seasons. 

Keeping Customer’s ever changing requirements in mind, Appidi Technologies launched combined unit of Engineered Dehumidifier to control Temperature, Relative Humidity and Filtration. The air handling units are integrating pieces of equipment consisting of fans, cooling coils, heating coils, air controls dampers, filters. The purpose of this equipment is to collect and mix air from the Desiccant Rotor with that returning air from the building space. The air mixture is then cooled / heated, after which it is discharged to the building space. The Centrifugal / SISW / Plug fans pulls air from the occupied / process areas of the building through return air ducts. Return air partially goes to the Dehumidifier along with fresh air and the balance air is directly by passed to the post cooling coil section of the ENG. Dehumidifier. Thus mixture of air from Dehumidifier rotor and the return air is called the process air.

Appidi Energy Recovery Units (ERU) heat recovery is a plate or rotary type air-to-air heat exchange designed to provide maximum energy efficiency in ventilated systems where heated or cooled air is let out and outdoor air is let in. In applications where ventilation is required or recycling of the same air is not allowed, energy recovery wheels or plate heat exchangers are used to recover the energy from exhaust air. This reduces the initial investment in HVAC equipment and minimises operating costs. Since HVAC equipment is typically the largest source of energy consumption in commercial buildings, ERU investments are economically justified for outdoor air makeup. In new HVAC installations ERUs also allow ventilated systems to be sized with smaller compressors, lowering initial costs of the HVAC package.
