Steam curing equipment, system engineering

The manufacturer’s signature equipment for precast, prestressed, pipe, masonry and tile curing, generates large volumes of controllable, low-cost steam. Operating at half the cost of traditional boilers, engineers note, CurePak can show return on investment in two years or less. Its capacity to produce steam instantly and initiate combustion prior to water contacting hot air equates to nearly 100 percent thermal efficiency and carbon monoxide risk reduction. CurePak also fits precast operations with flexible curing parameters, especially those requiring both intermittent and continuous steam flows.

A technical support team can quickly respond to user inquiries or troubleshooting matters by phone or in person, or schedule the mobile service center for preventative maintenance calls. The company extends technical support with training during plant start up and service calls. Curing equipment start up services include safety lockout and electrical testing; component interface and system functionality checks or full inspection; supply gas, electrical voltage and water pressure gauging; plus, documentation and follow up reports.

Users can also contract for different levels of turnkey support, to include supervising plant personnel and working with local contractors for proper equipment and utility installation. Company’s energy and control audits assess all aspects of a manufactured-concrete operation: continuous and peak loads; type of energy needed; control of energy going into the kiln; how heat and temperature are circulated; and, hold times. Such review ensures proper sizing of equipment to promote optimal curing cycles. — Johnson Concrete Curing Systems, Cedar Rapids, Iowa, 800/553-5422;

Micro-granulated, iron oxide pigment spray dryers with 20,000 metric tons’ annual capacity have entered full operation at Cathay Industries Group’s new manufacturing site in Tongling, China. “Cathay is now in the position to expand its broad portfolio by yet another important product line,” says CEO Terence Yu. “There are not many companies in the world that are able to manufacture top quality spray-dried iron oxide granules.”

Marketed under the CathayGran brand name, the new pigments exhibit excellent flow and dispersing properties, he adds, and suit virtually any automatic dosing system on the market. They exhibit a well specified particle size and can be handled practically dust free for use in sensitive working environments. CathayGran pigments are packaged in 25-kg and bulk bags.
