Air Washer & Evaporative Cooling Unit

The double stage evaporative cooling process works as a combination of a humidifier and a air purifier. The Indirect Evaporative Cooling at stage one builds on the strength of cooling by using water evaporation without increasing humidity in the supply air. This helps in removing sensible heat from the primary supply air stream thus providing 70-75% indirect saturation efficiency. The Direct Evaporative Cooling at stage twp productes near adiabatic cooling thus resulting in a total two stage saturation efficiency of 110-115% for the most comfortable, healthy cooling.

Features

Double stage cooling allows the use of energy saving evaporative cooling technology for design conditions where direct evaporative cooling is inadequate.
The energy consumption is around half than that of air conditioning, while the capital cost is also significantly lower.
The conditioned space is cooled by 100% fresh air, hence there are no IAQ related problems.
Since no refrigerant is used, the system is environmentally friendly.

Raised Floor Air Handling Unit

Raised floor Unitary Air handling product is specifically designed to meet the unique requirements of under floor/Raised floor air systems. This special AHU is designed to deliver air into a raised floor plenum while using up to two different air streams: primary pre-treated air, and a mixture of bypass space return air and return air chilled using either chilled water or DX coils.

Features

This Next Gen AHU is equipped with many unique features that make our equipment durable, easy to operate and maintain. Some of these features are:

The product is designed to consume low fan energy, has very quiet operation, and has a very compact space footprint.
Under Floor unit is manufactured in two modules for fan and coil sections. Each of these can rotate in any of the four directions with respect to each other, so that coil headers, filter access and supply air outlets can be selected for any direction to overcome internal constraints of the room.
The unit casing is fabricated out of specially designed engineered thermo-acoustic lined double skin 46 mm thick panels, resulting in lower noise levels and optimal thermal properties
The complete fan and motor assembly is mounted on suspended spring isolators and complete assembly can be easily slid out of the unit for maintenance.
Similarly, the coil is mounded on roller balls with quick lock header couplings and is easy to slide out from the front sided for maintenance.
Optional Accessories
The units come with highly efficient electronically commutated fans & AC/ BLDC motor as an option.
