IR Closed Evaporative Cooling Systems

Do You Need a Closed Cooling System?

If you have water-cooled compressors in your plant the answer is yes!

Closed cooling systems virtually eliminate all of the operational problems associated with other cooling water sources, such as city supplies, rivers, wells or lakes and open style cooling towers.

 

Specifically, a properly designed closed cooling system will:

  • Reduce or eliminate water and sewer costs
  • Minimize corrosion of cooling system components
  • Virtually eliminate dirt build-up and fouling of heat exchangers and other compressor cooling surfaces
  • Eliminates algae and bacterial growth common on open style cooling towers
  • Maintain peak cooling efficiency of compressor coolers. Virtually eliminates all compressor cooler maintenance
  • Provide maximum freeze protection during cold weather operation
  • Allow compliance with environmental regulations
  • Provide the lowest operating costs possible

 

Closed Cooling Systems

Closed evaporative cooling towers and fluid coolers are two types of closed cooling systems commonly used to cool compressors. Both types utilize an air to liquid heat exchanger to cool the fluid, a water and glycol mixture (coolant), circulating through the compressors cooling circuit.

The heat generated by the compressor is removed through the air to liquid heat exchanger.

Air, with a cooling spray of water (evaporative), or air alone (fluid cooler) flows across this heat exchanger assisting in the heat removal process.

Both types of closed cooling systems assure peak compressor performance and minimal operating costs.

The compressors cooling surfaces remain clean since the fluid is isolated from the ambient air and it’s contaminants.

  • Corrosion inhibiting properties of the glycol protects the cooling surfaces from rust, corrosion and scaling.
  • The glycol/water coolant mixture prevents winter freeze-ups.Water and sewer costs are greatly reduced or eliminated. Allows compliance with water and sewer regulations.

 Dry Fluid Coolers

IR Fluid Cooler

The Ingersoll-Rand Dry Fluid Coolers are designed to meet your cooling requirements while minimizing or eliminating expensive water and sewer costs. All IR Fluid Coolers are UL/CSA approved and feature a weather-proof enclosure which contain all necessary electrical components.

Casing  – Built to last with corrosion resistant bright aluminum sheet. The casing is divided by baffles, into individual fan sections, to ensure proper air distribution through the coils and maximize efficiency at part loads.

Fans  – Made from durable aluminum and balanced for quiet, vibration-free operation.

Fan Motors  – 460 volt, 3/4 HP motor TEAO (Totally Enclosed Air Over) and mounted on rigid galvanized steel supports.

Electrical Controls  – All electrical components are located in a weather-proof enclosure which is integral to the IR Cooler. A built-in disconnect is provided as a standard feature. Installation costs are greatly reduced. Fan cycling is also provided as an energy saving feature on all multi-fan coolers.

Single and Dual Pump Module  – The module comes complete with industrial grade, close-coupled, centrifugal pumps. The pumps are mounted on a common base and include inlet and discharge piping with throttling, isolating, and check valves. Smaller pump models are housed in an aluminum enclosure. Automatic switch-over and pump failure alarm contacts are standard features.

Coils  – Constructed with copper tubes and aluminum fins for maximum performance. Coils are Ieak tested at 300 psig, dehydrated, evacuated, and sealed prior to shipment, to ensure safe, reliable operation.
