Schaefer Ventilation Equipment

The WayCool portable evaporative cooler moves air farther with greater cool air output, smaller size and lower costs. It offers a UL-approved two-speed motor, high efficiency evaporative cooling pads on all four sides, high impact ABS plastic construction with an aluminum interior frame and a re-circulating submersible pump. Pneumatic wheels, manual or continuous fill options, automatic shut-off kits, water cleaners and conditioners are also available.

Greg Branson of Sunrise Energy Systems in Fort Wayne, Ind., recently used the WayCool cooler to both cool workers and add moisture to the air to prevent some exotic woodwork being installed from drying and cracking. “The evaporation process added the right amount of moisture to the facility to help solve this problem,” he said.

Ground Heaters

The new E1100 is specifically designed for builders, utilities, municipalities and small construction contractors. It offers more convenience features over the previous similar-capacity unit. Built with a new side access panel, the E1100 is easier to maintain and repair than previous units. A three-way valve replaced separate fill and suction valves, allowing no-mistake Heat Transfer Fluid refills. It is equipped with 1,100 feet of hose and its 126,000 BTUs/hr hydronic heater brings the propylene glycol Heat Transfer Fluid up to 180 F.

Richard Tjepkema, a site superintendent for Clark Builders, Edmonton, Alberta, used a Ground Heater to cure concrete grade beams during the wintertime construction of a church. “The heater worked beautifully,” says Tjepkema. “What most impressed me was the reliable, even heat it produced. From one end to the other, I knew that I had even heat. That's one of the biggest problems with using propane heating alternatives — the concrete can be too hot close to the source of the heat and still freezing on the other end.”
