C = Gas & Liquid Chiller

Cool Mass Series

Pioneer's CoolMass Gas & Liquid Chillers have a myriad of uses in industrial, food processing, medical, chemical, packaging, and other applications.

· Improve Product Quality
· Reduce scrap
· Reduce costs
· Increase tool life
· Increase production
· Recover heat
· Micro Processor Controller for precision temperature control. Standard for NEMA 1 and NEMA 4; not available for NEMA 7.
· Heat exchanger and tank combination feature (patent pending) increases cooling capacity, provides more consistent temperature and minimizes loss of cooling capacity to ambient.
· Rust free – The heat exchanger, tank and all cooling fluid piping are constructed of copper or brass providing rust-free service. Stainless steel construction is available.
· Cleaner fluid – Rust-free, closed-loop sealed fluid flow is standard, preventing algae and atmospheric contamination problems. Kleen Water Filters are recommended to remove particles that may be picked up during use of the cooling fluid.
· Cycling saves – Cool Mass chillers cycle just like your refrigerator and air conditioner. For most applications, the chillers should be sized for the maximum heat load under the most severe ambient conditions with a 10-20% buffer for contingencies. Because the heat load and ambient conditions generally vary, the Cool Mass design uses energy in proportion to the actual heat load being placed on the refrigeration system, thus saving energy and decreasing wear on equipment. The design incorporates a storage for cooling capacity (Cool Mass). This feature provides for added capacity during peak demand and turns refrigeration off during low load.
· Faster response – Once cooled, the Cool Mass design reduces the time required to lower fluid temperature during startup.
· Cylinder unloading (standard in C2400/CU2400 and larger) further improves the efficiency of Pioneer Cool Mass chillers by providing variable compressor capacity.
· Freeze protection is standard.
· Automatic pump down (standard in C2400/CU2400 and larger) saves on refrigerant loss and increases compressor life.
· Discus semi-hermetic compressor (standard in C2400/ CU2400 and larger) saves up to 10%.
· Unique discus valve design increases capacities, minimizes re-expansion gas, and improves volumetric pumping efficiency.
· Saves up to 10% in energy costs.
· Includes service valves, deep oil sump, crankcase heater and solid state motor protection.
· Capacity control.
· Crankcase oil level sight glass.
· Positive Displacement oil pump maintains required lubrication.
· UL recognized–60 Hertz.
· C.S.A. approved–60 Hertz.

The heat exchanger and the tank combination design-exclusive to Pioneer Cool-Mass Cycling chillers- is a variation of the patented Triple-tube design used very successfully in thousands of Pioneer refrigerant dryers.

Also available:

· Duplex pumping systems.
· Dual pump and dual circuit chiller systems for high temperature applications.
· Chiller/heater combination systems

Cool Mass Ultra High Efficiency Cycling Chillers

Lower temperatures and energy savings. Pioneer's Cool Mass Ultra utilizes an evaporative condenser to yield lower temperatures while saving on energy costs.

Principle of operation

The vapor to be condensed is circulated through a condensing coil, which is continually wetted on the outside by a recirculating water system. Air is blown upward over the coil, causing a small amount of water to evaporate. This evaporation removes heat from the coil, cooling and condensing the vapor in the coil to temperatures lower than either air-cooled or water-cooled condensers.

Energy Savings

Evaporative condensers offer energy savings by requiring lower system horsepower than conventional air-cooled and water-cooled condensing systems. Saves up to 30% compared to air-cooled systems

Evaporative condenser capacity is a function of ambient wet bulb temperature while air-cooled condenser capacity is a function of ambient dry bulb temperature. Since design wet bulb temperatures are generally 15 to 20 F lower than design dry bulb temperatures, using evaporative condensers, the condensing temperature can be 15 to 20 F less, resulting in compressor and system horsepower savings of up to 30 percent.

Saves up to 15% compared to water-cooled systems. The evaporative condenser rejects heat directly to the ambient air in one step of heat transfer. In the shell-and-tube condenser/cooling tower system, heat must be first transferred to the cooling water by the condenser, and then to the atmosphere by the cooling tower. The single heat transfer step in the evaporative condenser provides lower condensing temperatures and compressor horsepower savings of up to 15 %.
