Outdoor Air Cooled
Outdoor Air-Cooled Systems
Outdoor air-cooled systems are specifically designed for outdoor use and exposure to the elements. Heat rejection is obtained by pulling outside air through a condenser coil. Heat is transferred to the ambient air as it travels past the condenser, and is released back into the atmosphere. This system works extremely well in most applications where outdoor conditions and weather are seasonally stable. During hot summer months outdoor air-cooled systems tend to consume more energy due to less efficient heat transfer resulting in longer running time.
Indoor Water-Cooled Systems
These systems are ideal for applications in which the building already utilizes a chiller system to manage building temperature. Heat transfer is achieved using water that is circulated through a coaxial tube & shell heat exchanger. The overall efficiency of a water-cooled system is excellent, and improves compressor capacity by 10% -15% over air-cooled systems. Water-cooled systems are available from single compressor individual models to multi-compressor refrigeration racks. This system design is ideal for hotels, casinos, university, or any buildings equipped with a cooling tower. Water-cooled systems are almost always located inside what we call the mechanical or compressor room making service and maintenance easy.
Indoor Air-Cooled Systems
Indoor air-cooled systems are identical to the outdoor design, just minus all the weatherproofing and exterior metal housing. These systems are typically limited to smaller horsepower units that don’t require large volumes of refrigerated area. A fresh air supply / exhaust ventilation is sometimes required with this application. The advantages to this system are units are not exposed to the outdoor elements and are less expensive to install.
Multi-Circuited systems combine from 2 to 15 compressors into a custom-designed prefabricated air-cooled refrigeration rack. Our condensers coils are circuited for up to 5-compressor saving valuable space and cost. With roof space typically being a big concern, the multi-circuited system design works to fit your system needs into the smallest possible space. This design approach is also ideal for easy servicing and maintenance, making the Multi-Circuited system a smart choice for many situations.
A parallel system design strategy involves piping two to three compressors together “in parallel” to do the same job as what would normally be a five to fifteen compressor refrigeration rack. This approach can apply to both Air-Cooled and Water-Cooled models. Compressors are cycled on or off as the system load calls for using our specially-designed digital controller that monitors system suction pressure, discharge pressure, and also equalizes compressor run times. Parallel systems are our most specified design due to the many benefits it provides, including flexibility with adding or removing refrigerated fixtures, lower energy costs, and lower equipment and installation costs due to fewer compressors and less piping required. Parallel is the most practical way to go for any system requiring more than four compressors to handle the job.
Our Individual systems are available from 0.75 to 30.0 horsepower units and are available in indoor/outdoor, water-cooled, and air-cooled models. Individual systems are single compressor units that are sized and designed to be used for single refrigerated fixtures or multi-plexed for multiple refrigerated fixtures.
Eco-Friendly Glycol Chilling
Glycol Refrigeration Systems
Glycol systems are referred to as “Green Refrigeration”. Glycol systems have a reduced freon charge, and are specifically designed to chill propylene glycol, providing accurate temperature stabilization inside the refrigerated fixtures. Glycol systems perform best in medium temperature applications, and are competitively priced versus CO2 systems. As the world continues to address our global warming crisis, glycol systems will be a viable refrigeration solution in helping protect our planet for future generations.
