S Cleats & C Cleats

Slip and Drive Cleats system is generally used for lowend, less-critical applications. Traditionally, only the Drive cleats (“C”) which are positioning cleats were used for all four sides. This was giving a poor joint. The Slip cleats (“S” / “Standing S”) on the alternate opposite sides provide the moderate rigidity to the joint. While installing, Drive cleats are always fitted on the shorter sides and Slip cleats on the longer sides.

Pressure relief Damper & Non Return Damper

ACEVAC Pressure relief dampers for gas fire extinguishing systems and transformer substations, Air leakage with back pressure to EN 1751, class 4 Maximum differential pressure: 5000 Pa, Differential pressure can be adjusted from 50 – 1000 Pa (B > 600 mm: 600 Pa max.), Blades made of aluminum/GI/SS, casing made of galvanized steel /SS Blades open when the maximum differential pressure is exceeded and close automatically when the pressure drops, Blade locking with permanent magnet Robust, maintenance-free construction Available in standard sizes and many intermediate sizes Operating temperature 0 to 80 °C.

Optional Equipment And Accessories

Installation sub frame, Powder coating (RAL or DB), Stainless steel construction with stainless steel casing; blades made of aluminum

Application

Pressure relief dampers of PRD for the protection of internal spaces from differential pressures in excess of set maximum levels, when the set maximum differential pressure is exceeded, the blades automatically open to relieve the excess pressure Pressure peaks will be reliably controlled Differential pressure can be adjusted from 50 – 1000 Pa (B > 600 mm: 600 Pa max.)

Special Characteristics

Robust, maintenance-free construction, Maximum differential pressure: 5000 Pa Air leakage with back pressure, in closing direction, to EN 1751, class 4 Damper for negative or positive pressure (air extract or discharge) Operating temperature 0 to 80 °C Maintenance-free DU bearings with Teflon coating, bearing shafts made of stainless steel Each blade is locked with a factory set permanent magnet Adjustable differential pressure for blade opening: 50 – 1000 Pa, depending on width

Functional Description

Pressure-relief dampers open and close automatically. The blades are kept closed by magnets. If the differential pressure exceeds the set maximum value, the magnetic force is overcome, and the blades open. The airflow by which the excess pressure has been caused can now flow through the damper. The pressure peak is immediately and reliably controlled. The blade opening angle depends on the differential pressure and the volume flow rate. When the differential pressure drops below approx. 30 Pa, the blades close again.

Non Return Damper

ACEVAC Non-Return Damper which is an HVAC damper being used in the places where only one direction is required to flow air. Depending on the application, non-return dampers may be placed on the wall or duct. They are most frequently used in the presence of fans where the blades are only opened when the fan starts and the blades close because the fans stop.

Fire Damper

Construction

Frame: High quality galvanized Iron Sheet of 1.6mm thickness.
Blades: Interlocking type blades roll formed from 1mm thick galvanized steel. Blade Ramp: Formed from 1.6mm thick galvanized steel with a spring holder.
Springs: 2nos. constant force stainless steel springs.
Fusible Links: UL listed fusible links which has fire rating of 165° F / 212° F the shorter sides and Slip cleats on the longer sides.

Applications

Fire damper is a device installed in an air distribution system or an air transfer opening designed to close automatically upon detection of heat interrupting airflow and thereby restricting the passage of fire in the process. Fire dampers are installed in fire rated walls/barriers/partitions (sleeve required) where the HVAC ductwork penetrates ensuring that their integrity is maintained. The location and installation procedure of fire dampers should be in accordance with the widely accepted and recommended standard, NFPA 90A – Standard for the installation of Air-Conditioning.

By Pass VAV

Construction

Casing: High quality galvanized steel sheet of 0.9 mm thickness
By-Pass balancing damper: 0.9mm field adjustable balancing damper on the bypass outlet.
Actuator: 0-10 Modulating actuator.
Acoustic Media: Interior surface of unit casing is acoustically and thermally lined with ½ inch, 32 kg/m density glass fiber with high density facing. UL listed and meets NFPA 90A and UL 181.
Transformer: Step-down transformer, 240-24 V
Thermostat: 0-10V, Analog or
Digital Capacities range from 50– 3200 CFM in 8 sizes
Casing construction meets SMACNA standards and provides excellent strength and rigidity. Thoroughly sealed to prevent air leakage

Applications

ACEVAC Variable Air Volume (VAV) Control units are ideal for low and medium pressure applications. These units are suitable for both cooling and heating systems. The temperature can be preset on the electronic analogue/digital thermostat, which senses the room temperature and controls the VAV Unit. The required quantity of air to each zone is pumped in to the serving area based on the load requirement and the balance air bypassed through the bypass section of the VAV unit above false ceiling or to return air ducts.

Pressure Independent VAV

VAV System Works

The air passes into each zone from the ductwork through individual VAV boxes. A temperature sensor located in each zone is connected to its VAV box and opens or closes the VAV box to maintain the defined temperature set-point. As the
zone becomes satisfied, the VAV box modulates to a closed position. As the Zone’s requirements become satisfied, the pressure in the ductwork begins to rise as the openings in the ductwork close. Variable Air Volume systems, are used
to control both the ventilation and temperature to satisfy the requirements of a building.

VAV Applications

Residential & Commercial Buildings, Airports, Office space, Hospitals Hotels, Retail stores, Shopping Malls, Educational facilities, Indoor Games, Stadiums, Theaters

Construction

Casing Casings are made of high quality Galvanized Sheet Steel of 1.0mm Thick. Internal Insulation VAV Boxes are Internally Insulated with ½ Inch or 1 Inch Acoustic Liner (in compliance with project requirement). Metal encapsulated edge prevents cut fibers of the insulating plate falling off, and avoids erosion in the air stream.VAV Damper Shafts VAV Damper Shafts are made of 12mm Dia Round Solid Composite Steel shafts, which prevents condensation and breakage. Damper Gaskets Blade edges are sealed with Rubber Gaskets, preventing air leakage and for an air tight operation with low leakage characteristics.

VAV Sound Attenuator (optional only) VAVs are provided with Sound Attenuator as an optional (upon request), where excess noise to be decreased or controlled Maximum. Flow Grid Differential Flow Grids are located inside the VAV inlet with pre-calibrated holes with die cast aluminum junction, which measures air volume accurately. Electric Duct Heater (Optional only) Terminal shall include an integral electric heater, where indicated on the plans. The heater Control Box shall be constructed of not less than 20 gauge galvanized steel. Heater shall have a hinged access panel for entry to the controls.

Sound Attenuators

ACEVAC offers the design and engineering assistance to integrate our line of duct silencers, sound attenuators into a system solution. As a result you may choose from a selection of standard or custom engineered duct silencers that will
satisfy the requirements of each application. Prime candidates for noise control measures are openings into and out of noisy environments. This includes the ventilation of buildings, enclosures, and equipment rooms. Integration of noise control measures such as silencers and louvers, into the system design requires careful consideration of space constraints, fan selection and aerodynamic pressure losses
