Applications & Design

HY-SAVE combines unique  designs that are a result of years of analysis of the inefficiencies of the other methods of system operation.

They are extremely simple and yet they conform to all of the refrigeration principals. Here is why they are far ahead of other systems on the market. Our designs relate to "Floating Head Pressure" technology in as much as delivering refrigerant liquid at low ambient conditions.

Reduced Refrigerant Charge  -  Without a doubt the cost of refrigerant has risen to a level that is of great concern to the operations manager.  This waste of refrigerant is one of the considerations that have been addressed in the development of the Plus II system.   With the Plus II system, only enough refrigerant is needed in the receiver to meet changing conditions of the system and none is required for head pressure control.  The necessity of flooding the condenser with refrigerant has been eliminated.  This design will reduce the amount of refrigerant on the high side by as much as 50%.  This equates to less finance invested in the system and less spent if a leak should occur.  Higher capacity of the condensers is achieved.  Thus, fewer fans are required for a given condensing temperature.

Less Energy Use - With the small margin of profit associated in the average supermarket, anything spent on energy decreases the net profit.  Eliminating the wasted energy adds directly to the bottom line.   Operating at high head pressures and underfeeding of the expansion valves and evaporators is a waste of energy and money.  The Plus II system along with the LPA (liquid pressure amplification) will allow the system to operate efficiently and give more cooling for less.

Increased Cooling Capacity - With the Plus II system, expansion valves and evaporators can maintain top performance because 100% solid liquid refrigerant is delivered.   Even greater cooling capacity is achieved as condensing temperatures are lowered.   As an example, a refrigeration system can decrease the kilowatts per kilowatt of cooling by as much as 27.5% when condensing temperatures are lowered from 35oC to 21oC.

Product integrity - Spoilage of product is a direct result of poor case temperatures.  Systems that are not pumped may have trouble reaching the desired case temperatures.  The capacity of the evaporators in the cases is directly related to the percent of vapor     (flash gas) entering the evaporator through the expansion valve.  The Plus II System overcomes piping losses and assures the maximum capacity of both the evaporator and the expansion valves. 

Reduced Maintenance - As with any mechanical piece of equipment, reducing the heavy load and strain on the equipment will ultimately reduce the upkeep.  Reduced pressures and vibrations on the piping will result in fewer leaks in the system.
