Pavement binder

Road Oyl is a resin-modified emulsion product that controls dust and erosion on unpaved highways, construction sites, and walking paths. The product can be applied with a standard spray truck. Because it is made from natural ingredients (pine resin and pitch), it can be used in areas of environmental sensitivity, such as landfills or wetlands. Midwest Industrial Supply. www.midwestind.com.

Spill cleanup kit

These emergency response spill kits are ideal for accidental spills at sites and in facilities. The kits are available in various models and include cleanup and safety supplies, such as absorbent pads and handbooks. They are available in 55-gallon drums and 5-, 10-, 15-, and 20-gallon watertight containers. Universal Valve Co. Inc. www.universalvalve.com.

Membrane filtration system

The PURON submerged membrane modules are designed for membrane bioreactor treatment of municipal and industrial wastewater. The module has an air nozzle that discharges air from the center of each fiber bundle at the base of the system, which effectively dislodges fibrous components. The module features 2-mm, hollow fiber membranes with a pore size of less than 0.1 micrometer. Each fiber filter is coated to prevent breakage during operation. The membrane blocks solids and particulates, including bacteria. Koch Membrane Systems Inc. www.kochmembrane.com.

Side loader

The MultiTask SL drop-frame side loader is ideal for refuse collection. It is available in 23-, 26-, 30-, and 33-cu.-yd. body capacities. The vehicle's packer cycle time is 12 to 14 seconds, and the compaction rate is 700 to 800 pounds per cu. yd. The Radial Crusher panel rotates 235 degrees from the back of the hopper wall, compressing and sweeping the refuse away. The Shur-Lock system allows operators to unlock the tailgate, discharge the load, and re-lock the tail-gate without leaving the vehicle cab. Heil Environmental Industries Inc. www.heil.com.

Compressors

The 3700V series of compressors includes the 3000V, 3700V, and 4500V, with 40, 50, and 60 hp, respectively. The variable-speed drive feature allows the compressors to adjust to changes in air demand. The compressors have sound levels as low as 68 decibels. Sullair Corp. www.sullair.com.

Flow meters

Stainless-steel Liquid Flo-Sensors measure flow rates electronically. The 104 and 107 models measure a variety of fluids, including fuels, light oils, solvents, coolants, pesticides, mild acids, and deionized water. The sensors can measure rates as low as 13 milliliters per minute. An analog 0- to 5-V direct current output and pulse output are standard. Four- to 20-mA outputs and an integrated display are optional. McMil-lan Co. www.mcmflow.com.
