  JCC Design/Build may be today’s smartest
way to build your business.		  
     
     
 
With more than 90 years of HVAC fabrication and installation service under our belts, it is not a stretch for many customers to think of JCC people as the experts when it comes to system design and energy management.

In fact, many of the General Contractors, architects and building owners we work with rely on JCC engineering expertise to either assist with or completely plan efficient and cost-effective systems within the structures they are asked to bid or build. Complete ventilation systems for manufacturers and healthcare facilities, as well as specifically purposed systems for dust and fume collection are challenges we frequently address.		   Industrial refrigeration and cooling systems is another area where JCC experience – particularly in the areas of energy management and environmental sensitivity – often proves to be a valuable resource.

Rock Island Arsenal Building 222		  
     
     
 

JCC Design-Build specialists were engaged by the Rock Island Arsenal to help solve a problem inherent in the specialized system they use to provide cooling to oven jackets and doors in order to maintain the proper oil temperature needed for their heat-treat process. The system also provides coolant to ovens responsible for the heat-treat requirement of specialized metals and tooling for an assortment of military equipment.

The new design required 141 welds and includes a closed loop system with filtration, stabilizing the coolant. This system consists of a reverse-return system that eliminates the use of balancing valves. The system, comprised of a 828 gal/min cooled water primary loop and 224 gal/min secondary loop, was sized to allow future expansion.

   The massive new 280-ton cooling tower accomplishes its mission in four stages: a first stage thermal exchange; second stage variable frequency drive cooling fans; and third stage spray pumps in the tower, adding evaporative cooling. Fourth stage mechanical cooling consists of Trane chilled water units for additional stand-by cooling, if needed.
The chiller alone has 100-ton capacity.
