Page 7: Introduction
INTRODUCTION 1.1. General DuraQuench is an FM Approved, single‐fluid water mist system, that when configured for Deluge System operation provides active fire protection for large machinery spaces and turbine enclosures. The primary components of the DuraQuench Deluge system are a fire pump skid, patented K6 fine water spray nozzles, ancillary components such as deluge control valves, backflow preventers, isolation valves, and a reliable water source (i.e., public mains, gravity tanks or other suitable water sources). These components are connected together as a system to deliver water mist to the protected enclosure to control, suppress, or extinguish fires. With a minimum operating pressure of 112 psi (8 bar) and a maximum operating pressure of 232 psi (16 bar) at the system nozzles, the system is classified by NFPA 750, Standard ...

Page 9: Water Mist Principle
As the water spray is converted to steam, it expands approximately 1,700 times forcing oxygen away from the vicinity of the droplet. This results in dilution of the air (oxygen) supply within the protected enclosure. If the amount of oxygen necessary to support combustion is reduced below a critical level (13% – 14%), the energy output of the oxidation process falls below the level of energy input the fire requires to sustain the chemical fire process, which causes the fire to burn inefficiently making it easier to extinguish. Blocking of Radiant Heat As water mist is released into the protected enclosure, the fine water droplets block the radiant heat generated by the fire from getting to unignited fuel surfaces and reduce the radiant heat flux between the flame and the fuel surface.

Page 10: Enclosure Effects
(integrity) Enclosures shall be fairly air‐tight. Higher O2% = reduced fire‐fighting effect. Ventilation Ventilation shall be turned off prior to system activation. High heat output (larger fire) = more combustion gases and steam = Heat Output improved fire‐fighting effect. Low ignition temperatures = higher cooling effect on fuels = improved Fire Characteristics Fuel Types fire‐fighting effect. Low shielding = more water evaporation = more steam and cooling = Shielding improved fire‐fighting effect. Higher High = more steam = less condensation = improved fire‐fighting effect. Ambient Temperatures Low Low = less steam = more condensation = decreased fire‐fighting effect. Conclusions: Large Enclosures, Small Fires and Ventilation  Larger Enclosures = More Air and Oxygen = Slower Smothering of Fire  Small Fires = Less Heat Energy = Less Steam and Combustion Gases = Slower Smothering of Fire  Ventilation = More Oxygen = Harder to Dilute Oxygen Concentration = Slow or Non‐smothering of fire Small Enclosures and Large Fires  Small Enclosures = Less Air and Oxygen to Dilute = Faster Smothering of Fire  Large Fires = More Heat Energy = More Steam and Combustion Gases = Faster Smothering of Fire Page 4 P/N 06‐791‐1 (Rev. 3) 704 SW 10 Street, P.O.

Page 11: Water Mist Versus Traditional Sprinkler System
1.5. Water Mist Versus Traditional Sprinkler System Water mist has several advantages over conventional sprinkler systems. One of the key benefits of the DuraQuench system is that it typically uses 75% less water than a sprinkler system. With a water mist system, the majority of the water droplets are evaporated by the heat and hot gases generated by the fire resulting in much less water damage to the protected property and a dramatic reduction in down time for cleanup. In industrial applications, the reduced down time means that the facility will be able to resume normal operations very quickly after a fire event. In contrast, traditional sprinkler systems spread large water droplets over the protected enclosure to absorb heat and cool the room. Due to the large size and relatively small surface area of sprinkler water droplets, they will not absorb enough energy to evaporate and quickly fall to the floor as water. This results in limited cooling of the fire and greater water damage to the protected property causing a large increase in facility down time due to the fire event. 1.6. Approvals The DuraQuench deluge water mist system is FM Approved to FM5560 appendix E and F for active fire protection of machinery enclosures and turbine enclosure with exposed or insulated turbines with the following limitations: Volumes of 0 ‐ 28,252 ft (800 m ) Enclosure height up to 26.25 ft. (8 m) max. Nozzle installation height up to 26.25 ft. (8 m) max. Volumes of 28,252 ft (800 m ) ‐ 162,801 ft (4610 m ) Enclosure height up to 39.37 ft. (12 m) max. Nozzle installation height up to 39.37 ft. (12 m) max. 1.7.

EQUIPMENT The DuraQuench deluge water mist system consists of a number of K6 nozzles connected by a piping network and a deluge control valve connected to a continuous pressure pump skid unit which is connected to a suitable water source (i.e., public mains, gravity tanks, reservoirs, etc.). This section provides a description of the components offered by Fike that can be used to construct the DuraQuench deluge water mist system. 2.1. Sourcing System Components The DuraQuench pump skid unit and the K6 nozzles are the only two components that must be purchased from Fike in order to maintain FM Approval. The remaining system components including deluge valve, detection and control panel, valves, piping, switches, etc. can be sourced from other suppliers. The operating pressure requirement of the DuraQuench system allows the use of traditional FM Approved sprinkler components and deluge system valves. Components selected for use on the DuraQuench system shall be FM Approved for use in deluge sprinkler systems. All system components should be a part of a FM Approval follow up service. It is very important to verify that the ...

Page 17 Pump Skid Ordering Format The DuraQuench pump skid can be ordered with different pump controller and pump combinations. When ordering the pump skid, it is extremely important to verify the voltage and frequency (50/60 Hz) of the power feed supplying the pump skid before selecting the appropriate pump skid part number. The voltage and frequency of the pump controller and the pump selected must be compatible with the available power supply. The fire pump controller is available in the following configurations: 1) Standard single source pump controller provides across‐the‐line full voltage starting for the three phase motor driven pump. No transfer switch included. 2) Dual source pump controller incorporates a transfer switch directly into the standard pump controller enclosure. The transfer switch provides for automatic transferring of the pump load from one power source to another (self‐ acting). 3) Variable speed fire pump controller provides a variable frequency drive (VFD) built into the standard pump ...

Nozzle Spacing for Turbine Enclosures with Turbines with Exposed Casings The fine water spray produced by the DuraQuench system may cause too much cooling to the casing surfaces on exposed turbines. The uneven temperatures in the casing materials from the cooling by the applied water mist may cause tensile cracks to occur in the casing of un‐insulated (exposed) turbines, in the case of water mist system being activated and distributing the water mist on hot turbine casing without thermal insulation. In order to overcome this potential problem, the radius of the protected turbine is limited to a maximum of 14’‐9” (4.5 m) and the K6 nozzles must be installed as shown in Figure 30 with regards to the spacing and location of the nozzles in direct relationship to the un‐insulated turbine.

Page 47: 3.11.3.4. Nozzle Obstructions
3.11.3.4. Nozzle Obstructions NOTE: *Systems with nozzles installed as described in this section are not part of the DuraQuench system FM approval. Care should be given when placing the K6 nozzles adjacent to obstructions. A major obstruction is defined as any object that obstructs more than 30% of the water mist from one nozzle when observed from below the obstruction. See Figure 32. If the protected area contains one or more major obstructions, an additional nozzle should be installed adjacent to the obstruction(s). Depending on the elevation of the obstruction, additional K6 nozzles shall be installed below major obstructions (i.e., beams, walkways, ductwork, etc.) in order to provide a homogenous distribution of the water mist in the enclosure. Regardless of the distance between nozzles and obstructions, and distances from the obstructions and the application, additional water mist nozzles shall be installed below obstructions with a foot print area exceeding 3.3 ft. (1m) wide and 9.84 ft. (3m) long. This includes grated walkways. Areas in which combustible liquids and other such materials may accumulate shall be protected by additional K6 nozzles. Figures 31 and 32 below should be applied to calculate the shield factor of an obstruction. Figure 31 shows the typical water spray from one K6 nozzle.

The friction loss depends on the flow rate, the pipe size, the pipe length, and elevation changes in the system. Piping components, such as valves, fittings, backflow preventers, etc., must also be factored into the system friction loss calculations. Actual system friction loss shall be determined by hydraulic calculations. 4. Calculate the required total head for the pump. The required total head for the pump is the difference between NPSH from the connected water supply and the friction head loss of the pipe distribution system. 5. Select the pump. Select the pump based on the pump curve information provided in Annex D.4 and D.5, using the total head and flow determined in the previous steps. The selected pump must be adequate to meet both the flow and pressure demands for the system. NOTE: NFPA 750 requires that a fire pump(s) be selected to provide a minimum of 110% of the required system water flow and pressure; whereas, FM Property Loss Prevention Data Sheet 4‐2 requires that a fire pump be sized to provide 120% of the required system water flow rate, at the minimum system operating pressure. The following formula can be used to estimate the size and number of pumps required to serve the protected area based on the total water flow required. = Q / q PUMPS MAX Where: = Number of pumps PUMPS = Total flow for area (gal/min or l/min) + safety factor (10% NFPA or 20% FM) q = Flow rate output of selected pump unit NOTE: Using the formula above, in most cases, will result in the selection of a fire pump that is oversized for the application. Hydraulic calculations shall be performed in order to determine the actual required capacity of the fire pump. Page 44 P/N 06‐791‐1 (Rev. 3) 704 SW 10 Street, P.O.

(NFPA 750; 6.9.2.2). However, power feed shall be arranged so that if the power supply within the protected facility itself must be disconnected during a fire, the power supply to the pump feeder circuit will not be interrupted (NFPA 750: 6.9.2.3). 4.1.6.2. Power Supply Capacity Power supply shall be capable of carrying indefinitely the sum of the locked‐rotor current of the fire pump motor(s) and pressure maintenance pump motor(s) and the full‐load current of the associated fire pump accessory equipment. The following formula can be used to calculate the pump’s motor inrush current, also known as locked‐rotor amps or LRA. Simply insert the motor’s KVA/HP, HP rating, and Voltage values into the formula. LRA = (KVA/HP x Motor HP x 1000) / (1.732 x Motor Voltage) Detection and Releasing Panel Connections to Pump Controller The buyer is responsible for material and labor required to connect the detection and releasing panel to the pump skid controller for pump activation and monitoring purposes, where required. Refer to documentation supplied with the pump controller for connection requirements. Fike recommends that the fire detection control panel and associated control modules used to monitor and control the pump skid be located outside the water mist protected area so they are not subject to the effects of the fire, which could render them inoperable.

Page 67: System Restoration After Operation
SYSTEM RESTORATION AFTER OPERATION After system operation (test or fire incident), the following procedure must be followed to restore the DuraQuench system back to normal operation. The procedure is written around the use of the C‐EL deluge control valve. Once it has been confirmed that the test is complete or the fire has been extinguished, press the red STOP button on the front of the pump controller to turn off the fire pump. Notify remote monitoring entity and fire brigade that the water mist system is going to be taken out of service. Power down the fire pump controller by closing the Circuit Breaker Switch and then the Isolating Switch. Verify loss of AC power to the controller is indicated on the Detection and Releasing panel. Close the supply isolation valve [X] on the pump skid. See Figure 43. Verify that a supervisory signal is indicated at the Detection and Releasing panel. Disconnect the actuator from the C‐EL valve solenoid coil by loosening the attachment screw. With the solenoid coil still attached to the valve body, momentarily apply 24 VDC reverse polarity voltage (‐ to A and + to B) to the solenoid coil [B] as shown in Figure 42 to close the valve. Figure 42: Solenoid Valve Reset Reconnect the solenoid actuator to the solenoid coil and secure in place with the attachment screw. Open the system drain/test valve [Z] located upstream of the C‐EL control valve to drain the residual water from the system riser pipe. See Figure 43. Verify that a supervisory signal is indicated at the Detection and Releasing panel. Close the drain/test valve [Z] once water flow stops. See Figure 43. Verify that the supervisory signal event indicated in Step 8 clears. Turn the manual release lever [A] on the C‐EL valve to the open position to drain any residual water from the C‐EL valve via the valve trim drain. See Figure 43. Close the manual release lever [A] once water flow stops. See Figure 43. Clean the pump skid strainer per the procedure outlined in Appendix B. Inspect a representative sample (minimum of 10% of nozzles in the activated zone) of the system nozzles for contamination of nozzle strainer. If debris is found all nozzle strainers in the activated zone should be cleaned. See Appendix C. Close isolation valve [Y] on the pipe riser. See Figure 43. Verify that a supervisory signal is indicated at the Detection and Releasing panel. Open the supply isolation valve [X] on the pump skid and verify that the supervisory signal event indicated in Step 4 clears. See Figure 43. Verify that the inlet pressure gauge [C] on the C‐EL valve shows a build‐up of water pressure. See Figure 43. P/N 06‐791‐1 (Rev. 3) Page 61 704 SW 10 Street, P.O.

Page 68: Figure 43: Typical C-El Valve Riser
Verify that the outlet pressure gauge [D] on the C‐EL valve reads zero, indicating that the C‐EL valve is closed. See Figure 43. Verify that the supervisory event indicated in Step 14 clears. If the pressure gauge [D] shows a pressure build‐up between the isolation valve [Y] and the C‐EL valve, close isolation valve [X] and correct the problem before attempting to open isolation valve [X] again. See Figure 43. A pressure buildup indicates that either the C‐EL valve is not seated correctly; the manual release valve [A] is open; or the solenoid valve [B] is open. See Figure 43. Open isolation valve [Y]. See Figure 43. Reset the Detection and Releasing panel making sure that no events are present on the system. It is important that the panel be clear of all events (normal operation) in order to prevent the fire pump from restarting once power is reapplied to the fire pump controller. Power up the fire pump controller by closing the Isolating Switch and then the Circuit Breaker Switch. Figure 43: Typical C‐EL Valve Riser Page 62 P/N 06‐791‐1 (Rev. 3) 704 SW 10 Street, P.O.
