CHICAGO - NuTemp Inc., a leader in rental temperature-control equipment, has expanded the scope of its rental equipment specifically designed to meet the needs of the industrial process cooling market.
NuTemp has added to its rental fleet a line of heavy-duty industrial air conditioners, a 1,000-horsepower trailer mounted cooling system capable of supply temperatures to minus-40 degrees Fahrenheit, and a pair of rotary-screw industrial skids that offer unprecedented flexibility to meet the widely varying needs of the industrial process user.

Air conditioners

The NTIA-30 Industrial Air Conditioners are a complete packaged air-cooling system. They require only ducting to the area or device being cooled and connection to a suitable power supply.

These heavy-duty units, manufactured at NuTemp's Gonzales, La., depot, can deliver up to 12,000 cubic feet per minute of air at temperatures to 45 degrees Fahrenheit. Static pressures to 6 inches of water column (wc) are obtainable to allow long duct runs without compromising cooling ability. Each unit is factory-tested and set to job site requirements prior to shipment.

These units are well-suited for such diverse applications as low-temperature air, high air flow or long temporary duct runs.

Process cooling

The 1,000-horsepower, trailer-mounted cooling system - an industry first - was designed with great flexibility in mind and packaged to facilitate installation in the shortest possible time. The unit can operate on 2,300 or 4,160 volt power supply and requires no skid changes to make the switch.

The main motor starter is part of the skid package and all internal piping and wiring is complete, so that power need only be connected to one point to make the chiller operational. The unit features a rotary-screw compressor and includes a hot gas bypass system to allow continuous operation at zero load.

The industrial skids were also designed for greater flexibility and ease of installation. Provisions are made during design and construction to make it quick and easy to change from high-temperature, high flow applications to low-temperature, low-flow so that lead times are minimized.

The 700-horsepower skids, even though high-capacity and completely packaged, are able to be shipped without special permitting so that they can travel 24 hours to meet emergency needs. The skids feature a broad application range, are compatible with almost all process fluids and are capable of more than 100 tons at minus-40 degrees Fahrenheit.

Even though the skids were designed to be flexible, the first rental for one required modifications. NuTemp's customer, a Houston chemical company, needed more capacity than an existing air-cooled chiller was delivering, but had very limited power and space for a replacement.

NuTemp's efficient water-cooled skid provided the greatest capacity with the power available. The water-cooled skid would fit in the same pace as the air-cooled skid, but where to put the cooling tower? NuTemp solved the problem by building a support structure on the skid and installing the cooling tower on top of the chiller. The chiller fluid and condenser pumps were added to the skid and the entire package made suitable for installation in a Class I Division II environment.

NuTemp also has added a fleet of large custom portable cooling towers. These new cooling towers are designed and manufactured for the maximum cooling possible while maintaining easy portability. The towers are rated at 2,000 nominal tons of cooling each, are completely self-contained and can be running within hours of arriving on the job site. They are ideal for boosting the capacity of big field-erected cooling towers in chemical plants, refineries and utility plants. NuTemp offers a comprehensive range of equipment, such as:
