Smoke / Fire Control Devices

Smoke & Fire Dampers

We present a new range of dampers that are equipped with internationally proven and certified electronic or mechanical controls. Fabricated in strong GI construction, these dampers ensure the automatic shut off of air in the system and thus safety and protection in case of fire, smoke or rise in temperature. The dampers can be effectively used to control the fire and its spread through air handling system and can be availed at most reasonable prices

Application
Fire Smoke Damper performs the function of both a Fire Damper and a Smoke Damper. Building layouts and designs often combine fire rated partitions with smoke barriers requiring the installation of both a Fire Damper and a Smoke Damper at a same location. All type of Fire Dampers and Combination Fire Smoke Dampers must be qualified under UL Standard 555-1995 (presently prevalent in India and tested by Central Building Research Institute, Roorkee) as a Fire Damper. The consideration mentioned above applies to the selection and application of both Fire and Combination Fire and Smoke Dampers.

Tested as Per UL 555: 1995 for 90/180 min.

The Conaire CDM 40 will accomodate ionosation senseor or photo-electric sensor. It is easy to clean and maintain, since detector heads can be removed by simply twisting-in, twisting-out of its housing. The CDM 40 samples air currents passing through the duct accordingly signals the actuators / AHU's Fans / warning systems through Conaire control panel model CDM 41 or Central Fire Alarm Panel and hence preventing the spread of toxic smoke and fire gasesin protected areas. The duct smoke Detector / Actuator can be tested periodicallywith the help of remote control panel CDM 42 provided with the unit (optional).

Variable Air Volume Terminals

Variable Air Volume Terminals are designed to achieve variable air volume delivery of conditioned air to a room in single duct, constant volume air distribution system.

VAV Terminal uses a primary air damper working in concert with a bypass port damper. As the primary air damper closes, the bypass port damper opens, and vice versa so that a constant volume of air is delivered by the air terminal, but varying amounts are delivered to the room or the bypass plenum. A locking quadrant on the inlet balancing damper determines the total air flow through the air terminal.

Construction
Variable Air Terminals are constructed of galvanized steel. The terminal casing inlet plate and damper consist of 0.5mm thick galvanized sheet steel.

The universal control mounting panel and damper cylinder are 1mm thick Galvanized sheet steel, insulation is 25mm thick, coated fibrous glass that Complies with the requirements of NFPA 90A, ASTM C-665 and UL-181. The outlet plenum interior wall is lined with 0.4mm thick metal, preventing air flow insulation exposure to the room.

Performance
Variable Air Terminal are available for system pressure Dependent and system pressure independent applications. They are Recommended for use in duct systems with static pressure up to 50mm water gauge. Supply air capacity range from 200 to 1600 CFM, depending on air terminal size
