Technical Datasheet

Air Handling Unit

AIR HANDLING UNITS are manufactured according to the most advanced technical specification and under strict quality control. Each and every part of the unit is fabricated / manufactured in-house and goes through various tests before being fitted to the main unit. The complete unit is Factory assembled and tested for leakages, vibration, airflow, temperature variation, sound levels etc. Only after all the tests are completed, and qualified by the quality control department, the machine is shipped to the customer’s site

SASA air handling units are manufactured according to the most advanced technical specifications and strict quality control. Every part of the unit is fabricated/ manufactured in-house. The unit is fabricated/ manufactured in house and goes through various tests before being fitted to the main unit. Unit is tested in the factory for temperature variation, leakages, vibration, airflow, sound levels etc. After all the tests are completed and qualified by the quality control department, the machine is shipped to the customer’s site.

Today, from the deserts of Sindh to the mountains of the frontier region, SASA’s name has become synonymous with Quality & Reliability. The complete range of SASA Air Handling Units is made from the conclusion of optimum thermal design aerodynamic and acoustic performance. A wide range of 14 models provides nominal airflow ranging from 1000 cm to 28500 cm with a single or multi zone horizontal type arrangement meeting most of the HVAC applications and requirements. The units can be easily dismantled for transport and installed within the difficult entries.

  1. Pharmaceutical Grade Air Handling Units.
  2. Hygienic Air Handling Units.
  3. Industrial & Commercial Grade Air Handing Units.

Mixing Section of air handling unit

For applications having the requirement of mixing fresh and returned air, a mixing section with two dampers is provided.

Dampers

Control dampers are off the galvanized frame. Air dampers have opposed airfall blades.

Fan Section

Forward curved or backward inclined fans can be provided to suit the required applications. Forward curved fans are constructed of galvanized steel and are tested in accordance with ARI standard 430, suitable for external static pressure up to 2.5degree w.g. Backward inclined wheels are of mild steel construction, wide structure members to provide maximum rigidity and are tested in accordance with ARI standard 430, and suitable for external static pressure up to 6 w.g. Backward inclined wheels are of non-overloading characteristics.

A unique feature of this range of fans is the interchangeability of the impellers within the same housing. This feature allows upgrading or modifying the AHU as per the site’s requirement. The impellers are statically and dynamically balanced.

Fan Bearings

Fan bearings are the self-aligning type with grease-able ball bearings selected for a minimum of 20,000 operating hours. Bearings are provided with extended lubricating nipples for ease of periodic greasing. Generally, two types of ball bearings are installed on the fan shaft.

  1. Sealed-bearing is lubricated for life and is covered in a unique rubber anti-vibration housing, which provides sound insulation and smooth running.
  2. Pillow-block bearings are provided for heavy-duty fans; greasing nipples are provided for easy maintenance.

Vibration Isolation

Rubber isolators are standard for SASA SAH units with internally mounted motor and fan assembly providing excellent vibration isolation. Fan and motor are mounted on the same rigid, rugged steel frame as standard.

Flexible Connection

Fan discharge is connected to unit discharge by internal flexible duct connectors to reduce the unit’s vibration further.

Filters

Every type of filter can be integrated in the SAH unit.

Flat Filter

The Bag filters are provided in a separate section in the unit. Synthetic fiber Filtration media is used that is here and water-resistant, having a final pressure drop of 1.0 deg wg.

HEPA Filter

The Hepa filters are provided in a separate section in the unit, having an initial pressure differential of 1.0 deg wg to a final pressure drop of 2.4 wg.

Coil Section

SAH units Coil sections are provided for humidification and dehumidification. The coil sections include chilled water, hot water, direct expansion or steam coils. All soils are easily removable from the coil section of the unit.

Coil Assemblies

SAH units’ coils are designed and tested for maximum heat transfer efficiency between circulating mediums, i.e., air and water (Or refrigerant). The basic heat transfer at the coil surface has been perfected by fin contour and staggered tube configuration.
