Secondary refrigerants are used in for many special cooling applications; the most common secondary refrigerants in use are propylene glycol, ethylene glycol and water. A typical application for secondary refrigerants is a chiller package or a central compressor room connected to a high efficiency heat exchanger. These designs significantly reduce the operating refrigerant charge yet allows for a large number of areas and cooling devices to be serviced. The use of chilled water to provide cooling in medium and high temperature applications gaining attention, primarily in processing areas, often the chilled water is designed into thermal ice builders that use off peak electrical power.
For all large commercial and industrial applications requiring maximum refrigeration capability we provide the right product for the right application. We engineer and source high performance screw compressor packages that meet every design criteria of the project. The product we provide have a high reliability rate thereby minimizing maintenance and repair costs while maintaining low noise and vibration levels within the machine room.
With our optimized design, our parallel rack systems provide excellent reliability and performance for all refrigeration applications.
We start with the highest quality components, each fully tested to meet stringent reliability and refrigeration performance standards.
Our systems are built with advanced manufacturing processes that ensure the highest quality, and a three-step leak testing process that includes a highly sensitive helium leak test to ensure that there are absolutely no leaks.
Our Ingersoll Rand compressors have been designed with the latest technology for quieter operation, lower vibration and excellent energy efficiency. Superior design features result in built in quality and reliability.
Our distribution centers are complete pre-assembled “equipment centers” that integrate all your refrigeration, electrical and HVAC needs into one fabricated unit.
Each distribution center is designed to your specifications and custom built with your unique equipment needs. All equipment and components are in a pre-piped, factory-built package that reduces overall installation costs, shortens construction time and saves floor space
Our full line of air and water cooled condensing units offers you a solution to any refrigeration need, from single units for a critical temperature room to several units for a distribution or warehouse application.
Protocol is a “distributed” refrigeration system designed for specific product loads with the units being placed near the refrigeration demand.
By having the refrigeration system close to the refrigeration demand, your installation and operating costs are less, due to a reduced refrigerant charge, less refrigerant piping and fewer braze joints that reduce refrigerant leaks.
Energy efficiency is improved by incorporating vapor injected scroll compressors for low temperature and “optimized” scroll compressors for medium temperature applications.
Protocol has many environmental advantages including:
