An impressive array of new apparatus components and fire suppression equipment has been introduced in the first half of this year.

Among the products displayed at the Fire Department Instructors Conference trade show in Indianapolis were pumps, pump controllers, nozzles, monitors, vehicle monitoring systems, water systems, compressed air foam system (CAFS) units, engines and generators. Manufacturers include Elkhart Brass, W.S. Darley, Hale Products, Akron Brass, Cummins, Kochek Co., Fire Research Corp.

 Elkhart Brass of Elkhart, Ind., exhibited an electric remote control monitor, an Oscillating Rapid Attack Nozzle and a couple of unibody electric valves.

The Sidewinder EXM is Elkhart’s 700 gpm-class electric remote control monitor designed for fire apparatus. An offshoot of the company’s involvement with the U.S. Air Force’s research and development program on aircraft rescue firefighting (ARFF) vehicles, the new monitor is suited for wildland, ARFF, mini-pumpers, military specialty firefighting vehicles, skid units and station applications.

Don Sjolin, vice president of marketing and strategic development, said the monitor incorporates roller thrust bearings, as well as an electronics package built to NEMA 6 sealing requirements (that is, full submersion).

The Sidewinder EXM benefits from advanced computer-aided flow analysis and will flow 700 gpm, yet he said it is physically smaller than all current 500 gpm monitors.

The Oscillating Rapid Attack Nozzle (RAN) is water powered, has an adjustable sweep range and also a quick disengage mechanism for manual control. It can be installed as a retrofit to any rapid attack monitor.

Elkhart’s E3F and E4F Unibody Electric Valves embed microprocessor controls in the valves themselves, allowing valve position, pressure, status and flow to be broadcast and controlled across a two-wire network interfaced to the existing apparatus CAN bus, which eliminates wiring harnesses and third party interface systems.

With the embedded microprocessor, Sjolin said water, extinguishing agents, pump, power train and apparatus features can be integrated and supplied as a firefighting package, rather than a collection of components hung on a chassis. Operator control can be positioned in as many locations around the apparatus as desired.

The electric motors and actuators of the new valves are sealed to full submersion and rated in excess of 50,000 full load cycles.

W.S. Darley & Company of Itasca, Ill., introduced three new products at FDIC, the PuriFire Systems Model 3S3S and two low-cost CAFS units.

The PuriFire 3S3S is a three-stage water purification system integrated into a Darley Fast Attack firefighting skid unit. Company President Paul Darley said the unit’s stainless steel filter and UV housings are strong enough to handle pressure two times higher than traditional water purifiers do.

“The role of the fire service is changing to that of first responders now,” Darley said. “When you have natural disasters, people turn to the fire department first, and loss of power in an area means no drinking water. Our new unit can be built into pump modules, skid units or used as a stand-alone system.”

The PuriFire uses an advanced particulate filtration system composed of a self-cleaning strainer filter, two Ploydepth filters, and a carbon-block filter. Darley said together the filters can reduce the sediment level down to 0.5 micron and remove bad taste and odor from the water. The unit also uses a high intensity UV device to remove microbiological contamination such as bacteria, cysts and virus.

The two CAFS units introduced by Darley were the AutoCAFS HMBC 500/70 and the Odin Mongoose 70/35.

The AutoCAFS HMBC is composed of Darley’s HM 500 pump with an integrated belt-driven 70 cfm Vanair compressor that doesn’t require a clutch. The system is available as a midship, PTO or hydraulic drive. Its air compressor gauge panel includes an hour meter, air pressure gauge, oil temperature gauge, compressor high temperature and high pressure warning indicators, and a compressor unload switch with indicator lamp.

Darley said his company designed the system to drive down costs while not sacrificing quality.

“The compressor control system includes a means to unload the compressor system to minimize parasitic power load when CAFS is not being used,” he said.

The Odin Mongoose 70/35 (Odin is a division of W.S. Darley) is a 28-hp gasoline-powered unit with a Darley pump, Fast Foam injection system and Vanair compressor. It features a single pressure for CAFS – 125 psi.

“We’ve been listening to the marketplace,” Darley said. “These units are designed to allow fire departments on limited budgets to get into CAFS inexpensively, roughly at half the price or less than the cost of typical CAFS systems.”

Hale Products of Conshohocken, Pa., offered two new products at FDIC. The first was the TBP Twin Booster Pump – a two stage series/parallel pump that regional manager Shawn Kelly said meets the demands for higher pump performance for structural fires, while still retaining the ability to create the high pressures necessary to operate progressive hose lays and the capability of providing low speed pump-and-roll.

“The TBP is the first 750-gpm [National Fire Protection Association] rated two stage series/parallel PTO-driven fire pump in the market,” Kelly said.

The other pump introduced was the HP275 Attack Max, a twin hand line capable pump designed for easy installation by truck builders. The HP275 uses an air-cooled B35 V-twin overhead valve Briggs and Stratton Vanguard engine and comes in two configurations – 250 gpm at 125 psi or 180 gpm at 150 psi. The unit is 24 inches long, 24 inches wide, 31 inches high and weighs 190 pounds.

Akron Brass Company of Wooster, Ohio, displayed new and updated products, including a new vehicle data recorder (VDR) that meets the requirements of the 2009 edition of the NFPA 1901 apparatus standard.

Jeffrey L. Benson, product manager, said the VDR collects essential data that can be reviewed through an intuitive computer application. “Applying the data to training programs can improve response times, driver awareness and seat belt safety,” he said.

Restraint Indicator

Akron also introduced an Occupant Restraint Indicator, designed to tell the driver and the officer when and where restraints of occupied seats are properly fastened. In addition, the company exhibited its model 1230 self-educting firefighting nozzle, a variable-rate nozzle of anodized aluminum with a self-flushing feature.

Akron also displayed an updated style 538 cellar nozzle, a 500-gpm applicator with legs and a shutoff that throws out a 40-foot diameter spray pattern.

Cummins Inc. of Columbus, Ind., introduced a series of on-highway engines for 2010 that meet stricter federal diesel emission regulations set to take effect in January. The series of five different engines use selective catalytic reduction (SCR), allowing Cummins to decrease the amount of cooled exhaust gas recirculation so it could recalibrate the engines for stronger throttle response and better fuel economy.

The engines use fully integrated electronics, turbocharger technologies, a high-pressure common rail fuel system that allows multiple injection events per cycle and a special particulate filter.

Cummins Power Generation of Huntsville, Ala., a unit of Cummins, Inc., debuted a new SD20 Cummins Onan 20-kilowatt diesel generator that can be used in virtually any mobile application, according to Karl Wilson, business development manager for Onan Consumer Business.

A Larger Generator

“The previous generators offered only power up to 12.5 kilowatts, and we got a lot of requests from the field for a larger unit,” Wilson said. “We also plan to introduce a sound enclosure for the SD20-kw for those applications that need it.”

Lou Thomas, director of corporate sales for Kochek Co. Inc. of Putnam, Conn., said his firm made several product introductions at the show, including a new lightweight one-inch booster line nozzle, a Storz hydrant converter that converts existing threaded fire hydrants to quarter-turn Storz connections, and a series of aluminum nozzles (a 35-gpm constant flow, 10 and 24-gpm dual flow, and a 20 and 60-gpm dual flow).

Craig Lecy, regional sales manager at Fire Research Corp. (FRC) of Nesconset, N.Y., said his firm introduced a couple of upgraded products – the Incontrol 400, a pressure governor, engine monitoring and master pressure display, as well as the LED 900, a surface mount LED scene light.

The Incontrol 400 monitors and maintains desired water pressure, adjusts engine rpms for pressure fluctuations, has a digital master pressure display, uses highly-visible ultra-bright LEDs and is microprocessor controlled.

The LED 900 is 8 inches wide, 5 3/4-inches high and 1 1/2-inches deep. It runs on 12 volts DC, draws 6 amps and produces 5000 lumens of bright white light.
