Air Supply Unit (ASU) is equipment used to circulate, supply or replace air from spray paint booth. Air Supply Unit is commonly known as Air Replacement Plant (ARP), Air Handling Unit (AHU), and Air Makeup Unit (AMU) etc. Air Supply Unit or Air Handling Unit was very popular in areas where the air has low humidity, and hotter climate, mainly to comfort the human conditions in such climate. As technology has changed for better development, even in the field of paint and painting equipment, more and more expansions have added up to make a dust free painted product .To attain such a clean paint film on the product free from dust above 5 micron, Air Supply Units and Air Handling have become a necessity of today’s market.

Construction :

• The standard version of these units include galvenized metal sheet, extruded aluminium frame, PUF Insulation.
• Some of the optional features include thermal break constructions, louvers, supply air grilled plenum, instrumentation and control.
• The vertical air handling unit finds applications in many public offices, shopping malls and multiplexes.
• The vertical Air Handling unit is one of the best cooling solutions of the present times. It is truly made dreams a reality for people. The company possesses a great degree of skill and expertise in this field and strives to satisfy the clients in the best way.

Features :

• Compact size and low height with single/ multi centrifugal fan
• Direct Driven/ Belt options
• Units available in Double/ Single skin
• Double skin units available with Aluminium profile
• Direct driven units with single phase motors

Applications :

• Shopping Malls, Hotels, Hospitals, Pharmacheutical, industries and Industrial Units.

• DRAIN PAN Single Piece, Deep Drawn, Externally insulated G.I./Stainless Steel Drain Pan in weld less construction concept within built slope.
• SILENT FAN DECK comprising of specially designed Centrifugal Fans for low noise and spilt capacitor permanent lubricated / ball bearing motor for maintenance free operation.
• FLEXIBLE DESIGN The Return Air Plenum can be interchanged from back air suction to bottom air suction. Chilled water connections are flexible and can be changed either to right or the left side at site.
• RUST PROOF POWDER COATED/PREPAINTED FINISH The units are designed to be long life and more durable due to weld-less design and the powder coated/Prepainted G.I panels besides appealing looks.

Coil constructed with aluminium corrugated fins and seamless copper tubes. Copper fins and hydrophilic fins are anti-corrosive materials which are optional. The fins are designed purposely for better heat transfer efficiency and moisture carry-over limit performance. Capacity, water pressure drop and selection procedure is designed in accordance with ARI Standard 410. Cooling coils can be used when the face velocity does not exceed 2.5 m/s. For higher face velocity, a moisture eliminator is required to prevent condensate water carry over. For stacked coil in the coil section, drip pan is installed at back between coils to drain condensate to the main drain pans without flooding the lower coil section. The optional intermediate drain pan can be supplied for those needs to access for cleaning between the coils. Suvidha make Air Handling Units can handle both chilled water and direct expansion system.

It consists of opposed blades meter varying air volume through the coil and by pass to attain the desired temperature. It provides very low leakage in the face and bypass sections. Face and bypass damper can be provided for temperature modulation by bypassing air around the coil. The damper blades are fabricated of aluminium and continuous Thermoplastic Elastomer (TPE) seals are inserted onto every damper blade. The rotated rod of handle is made of brass and handle is fabricated of aluminium casting. The size of damper is decided by the air flow volume (m3/s) and air speed (m/s). The air speed go through the damper shall not exceed 7.5 m/s.
