Cargill

WinterPave® is an additive designed to help crews with winter pavement maintenance.

WinterPave® is an additive designed to help crews with winter pavement maintenance.

Cargill, North Olmset, Ohio, has announced the national release of WinterPave® asphalt anti-freeze. The product is specifically designed for helping make winter roads an easier maintenance item for public works officials and commercial contractors while providing an environmentally friendly option. Cargill is rolling out WinterPave asphalt anti-freeze technology in the United States after several years of adaptation, testing and development in Europe. The product is a proprietary additive that gives traditional asphalt anti-icing properties when mixed directly during production. “WinterPave asphalt anti-freeze will benefit the public by effectively helping reduce the bond of ice and snow to the pavement, creating safer driving conditions,” said Debby Capela, Cargill Deicing Technology business development manager. “Municipalities, commercial contractors and others who work to keep roads, bridges and parking areas safe for motorists and pedestrians will experience easier plowing conditions.”WinterPave offers these features and benefits, according to the manufacturer:

  • Mix directly with asphalt during production
  • Delays formation of slippery conditions caused by snow and ice
  • Longer margin of time for snowplow drivers to intervene during heavy snowfall
  • Releases fewer chlorides into the environment
  • Helps extend pavement life; may help the reduction of potholes

WinterPave asphalt anti-freeze helps prevent snowpack and ice from bonding to the pavement at surface temperatures greater than 17 degrees F, according to the manufacturer. “When we push snow and ice from the area over which the WinterPave asphalt was installed, we’re not seeing the ice and snow pack bonding that we see in other locations…” said Mark Jamison, transportation division manager for the City of Roanoke, Virginia. “The hard-pack doesn’t seem to be stuck to the road quite as hard. Once the road starts drying, it seems to dry a little bit quicker, which helps to minimize the extent of refreezing at night.” Environmental benefits of the product result in a reduced number of sodium chloride applications needed to melt away hard-pack. Once introduced to the asphalt mixture, the WinterPave asphalt anti-freeze product allows for slow and continual release of the anti-icing mixture onto the road surface. The anti-icing product is incorporated with asphalt during asphalt production, which creates a simple installation process that is the same as installing non-treated asphalt.For more information, contact Cargill at (800) 600-7258 or visit www.cargilldeicing.com.

Process Heating Company

The PHCo All-In-One Heater systems are pre-wired, pre-plumbed and ready for installation.

The All-In-One Heater Kit from Process Heating Company, Seattle, Washington, is a complete system that can provide direct heat to the asphalt tank, while also supplying hot oil for the plant. The primary feature of the system is the drywell-style electric heating elements that provide and maintain heat to keep liquid asphalt cement (AC) at the desired temperature. At the same time, the system circulates oil through scavenger coils and thermostat-controlled electric booster heating elements to provide hot oil to heat jacketed lines, pumps and valves, drags, silo cones, and other plant components. The scavenger coils allow for quick heat, while the booster coils sustain it for pinpointed locations. Booster elements also can elevate the oil temperatures above the controlled asphalt storage temperature, if higher-temperature hot oil is required. The system is designed to provide 100 percent efficient heat over its lifetime (often 30 years or more), as it reduces emissions and the associated need for expensive stack permits at the plant.

Using PHCo’s unique Lo-Density® patented Coil-Lock-Design heating elements, which reside within a drywell, the units dissipate controlled heat as low as three watts per square inch on the heater’s sheath, eliminating coking or damage of the AC and transfer oil. Because the drywell-style elements are accessible from outside of the system, they also may be serviced without draining the tank.Each All-In-One Heater Kit is a complete system that includes a high-temperature centrifugal pump that provides flow up to 85 gallons per minute (gpm) at 140 feet total head. The pump is skid-mounted and pre-plumbed, complete with shutoff valves and strainer. It includes a properly sized, vented expansion tank with a sight glass and a low-level shut-off switch. Like all fluids, heat transfer oil expands when heated. The expansion varies with the temperature to which it is heated. For example, 100 gallons of oil at 50° F will expand to 114 gallons when heated to 450° F. The expansion tank permits expansion of oil as it is heated, without exposing hot oil to air. It functions as an oil seal to accommodate the increased volume of expanded oil in a quantity of colder oil, which comes into contact with a limited amount of air. The low temperature of the oil seal will contribute to the long service life of the oil. A secondary function of the expansion tank is to provide a means for the escape or intake of air as the oil level in the tank rises and falls.

The system includes a UL-listed industrial control panel in a weatherproof enclosure, with standards that include a programmable time clock for early morning startup, main indicating controls and over-temperature controls. Also contained in the package are additional features on these heaters, including a strainer for easy cleaning, shut-off valves for the system and the fill lines. PHCo All-In-One Heater systems are completely pre-wired, pre-plumbed and ready for installation. Standard models come in 60, 100 or 125 kW total rating; custom sizes are available.

As an added benefit, the system has interlocking capability with other equivalent or larger electric users in the plant, to minimize excessive demand charges. For example, if an exhaust fan starts up at the plant, the All-In-One Heater shuts off, reducing overall energy consumption. The circulating pump will continue to run, however, and scavenge heat from the liquid for the plant’s hot oil needs.

TPF Inc.

TPF Inc., Cincinnati, has launched a new concept to prevent costly and dangerous asphalt overfills: the RAPTOR probe overfill protection system. The RAPTOR (Rapid Analog Pressure Temperature Overfill Response) System uses a 24-inch stainless steel gas-filled probe with an electrical output signal, which allows the data to be interpreted by the software on a PLC. The RAPTOR System probe is based on the simple principle: When gas is heated, it expands. Because the volume of gas is held constant in the probe, the pressure inside the system increases. This increase causes a spike in the system that is converted to an electrical signal interpreted by the software. A cut-off is triggered by a rapid change in temperature, caused either by contact with the probe, or by reaching a preset temperature. Check out the Here’s How it Works feature under the Departments tab.
