Air Condensing Chillers
Designed and built by GCI for the most demanding applications, DH Series Icewagon™ chillers are dependable workhorses with a broad range of capacities. Each air-cooled chiller is built to order with standard components and additional features to ensure reliable operation in critical applications.
Types of Air-Cooled Chillers
In addition to our Icewagon™ DH Series air condensing chillers for heavy-duty industrial use, we also manufacture low-temperature air condensing chillers (below -30°F) and extra-low temperature industrial air condensing chillers (below -75°F). Each type of air-cooled chiller features its own customizable models for specific industrial applications. Such as plant extraction with butane or propane.
Air-Cooled Chiller Features
A industrial, structural steel frame helps protect your air-cooled chiller from impact damage, and removable steel panels allow access for routine inspection and maintenance. The frame includes mounting pads.
DH chillers can be equipped with two compressors—a dual-circuit evaporator and a dual-circuit condenser—and wired for lead-lag performance. This allows one or both systems to operate depending on the seasonal heat load, which provides greater flexibility and can conserve electricity. Using a PLC control, complete dual systems within the same air-cooled chiller can offer total redundancy for critical applications. Three and four compressor models are also available.
DH Series chillers feature this unique modular type.
This feature delivers more precise temperature control by eliminating the constant on-off compressor short-cycling that results in excessive component wear and unnecessary power usage.
GCI will fit our own Coilmatic™ high-efficiency evaporator, a special low-flow evaporator, or a space-saving brazed plate evaporator based on your application.
A frequently selected option for DH Series air condensing chillers is a secondary loop, an additional heat exchanger installed within the chiller between the evaporator and the process. This component may be necessary to reduce the possibility of freezing the evaporator when ethylene glycol or methanol services are the primary coolant and water near 32°F is the secondary coolant. It may also be ideal when the secondary coolant is deionized water, oil, or thermal fluid, or when a large temperature drop is required. Secondary heat exchangers are fully enclosed in the air condensing chiller frame and may be brazed plate, plate and frame, shell and tube, or another design. Secondary pumps and tanks are also common.
Available for a wide range of coolants, stainless steel offers complete corrosion resistance, and the centrifugal-circulating pump has a high-efficiency impeller, centerline connections, mechanical seal. Vented tanks serve thermal purposes.
Extending throughout GCI air condensing chillers, our brazed copper piping is fully insulated, features bronze valves, and provides longevity, structural integrity, and protection against rust. Piping is optional for deionized water or food applications, stainless steel, or CPVC.
Controls include an easy-to-use digital thermostat in °F or °C, plus high- and low-pressure refrigerant gauges, pump pressure gauge, tank sight tube, and internal refrigerant sight glass. A remote interface is optional for air-cooled chillers, and extra digital thermometers are available.
This feature for air-cooled chillers includes a high/low refrigerant pressure safety switch, pressure relief device, motor overload protection, line and control circuit fuses, and pump switch interlock.
As another benefit to help keep your investment to a minimum, you’ll deal directly with our factory for your air condensing chiller customization. Our experts will help you select the right features so your air-cooled chiller is just right for your application.
We fully assemble and test all Icewagon™ air condensing chillers to your operating conditions before they leave our plant. Installation is simple, but we encourage you to contact us if you need assistance.
Outdoor and split systems are available on low and extra-low temperature air-condensing chiller models to -50°F.
