Bypass Type VAV Box

By-pass VAVs combine the advantages of proven air handling concepts to give complete zoning flexibility at lower cost from a single zone source. By-Pass VAVs complement by providing excellent temperature control and central air distribution by individually By-passing excess conditioned air to the main unit. The added costs of multi-zone systems can be avoided. Easy and simple to install, can be used with any Air conditioning units in any buildings or offices and can be easily modified or relocated as interior requirements. Capacities ranging from 35 to 1500 Ltr/sec. Unit casing is constructed out of 1.0mm (20g) galvanized steel sheet, acoustically and thermally lined. Internal insulation of 12.5 mm, thickness and 24 kg/m3 density. Loose linear edges are sealed and covered with metal sheet. Electronic thermostat and actuator provide accurate modulating by on/off control and is standard supply.

Pressure Independent VAV /CAV Box

Pressure Independent type VAVs combine the advantages of proven air handling concepts to give complete zoning flexibility at a medium cost from a single zone source. These VAVs deliver variable constant air volume as designed, by providing excellent performance and temperature control for central air distribution with unlimited zoning, combined with common by-passing with VZD - Variable Zone Damper (or VFD).The added advantage of multi-zone systems is by supplying centralized air distribution from unwanted zones to demand related zones. Easy and simple to install, can be used with packaged/ducted Air handling units in any buildings or offices and can be easily modified or relocated as per interior requirements.

Pressure Dependent VAV/CAV Box

Pressure Dependent Type VAVs combine the advantages of proven air handling concepts to give complete zoning flexibility at lower cost from a single zone source. These VAVs complement by providing excellent temperature control and central air distribution with unlimited zoning, combined with common by-passing with VZD -Variable Zone Damper. The added advantage of multi-zone systems are by supplying centralized air distribution from unwanted zones to demand related zones. VAV’s are temp and pressure dependent. Easy and simple to install, can be used with packaged ducted air handling units in any buildings or offices and can be easily modified or relocated as per the interior requirements.

Circular Pressure Independent VAV /CAV

Circular pressure independent VAV and CAV air volume control terminals. The terminals are designed particularly for systems with space and installation restrictions and for the accurate measurement and control of air volumes courtesy of the patented air flow sensor type Flow-Cross. In CAV application, the terminals maintain the required constant air flow independent to the inlet static pressure. In VAV application, the terminals control the air volume to the room, depending on the cooling load required thus saving energy consumption in both cooling and heating applications.

Air Flow Stations

The duct mounted airflow measurement station consists of single or multiple airflow elements, factory mounted and pre-piped in a casing designed for flanged connection to the ductwork. Standard materials consist of a G90 galvanized casing and anodized aluminum flow sensors, suitable for most HVAC applications. Flow transducers are available separately.

Venturi Air Valves

Venturi Air Valves are pressure independent flow control valves. The valve opening and the air flow volume are related on an equal percentage flow characteristics curve. The aerodynamic cone and its special built-in mechanism are designed to maintain a constant air volume independent of static pressure change, the air flow volume is mechanically corrected within one second and maintained constant without any actuator reset. No velocity air flow sensor is required before the valve to maintain the volume constant.

All desired air flow adjustments will be possible on site using the external dial and the valve label, no balancing or measuring devices should be required. Inlet and outlet connections to the valve will not influence the flow stability. The valve inlet and outlet are circular and of the same diameter. The body and the mobile cone are made of 18 gauge aluminum through spinning operation. Available in 5",6",8",10",12" Dia for CFM range of 20 to 1600 CFM.
