• Welded and sealed construction
• Conforms to ASME or UL requirements
• 3¼4" insulation
• Rugged shell and coil design
• 6 SCT models from 2 thru 18 tons

Subcooling is accomplished by refrigerating the liquid line of a system, using a higher temperature system. Simply stated, subcooling refrigerates the refrigerant.
The effect is to give the refrigerant more heat removal capacity by increasing the number of Btu’s each pound of refrigerant can absorb. The lower the refrigerant temperature the more heat removal capacity, resulting in a far more efficient system. Providing you with:

• Up to 20% increase in Btu loading
• Decrease in electrical usage as much as 25%
• Reducing pulldown time up to 50%
• Provide more uniform refrigerating temperatures
• Reduces first costs, by permitting down sizing of compressors in new systems

Application

Mechanical subcooling can be added to existing systems or designed into new ones. It is ideal for any refrigeration process where more capacity may be necessary, or where operating costs must be lowered. Often subcooling can be added using existing air–conditioning equipment to provide the subcooling input. Mechanical subcooling is recommended for:

• Supermarkets. Especially where present capacity is strained or additional loads (refrigerant cases) are being installed.
• Warehousing/Processing. To handle new load requirements or to permit expansion of the facilities.
• Industrial. To produce more capacity for changing product conditions or additional equipment.

Mechanical subcooling has proven cost efficient in a variety of applications. Additional equipment costs required for retrofit installations, in some instances, have been returned within three to six months due to lower energy usage. Further, subcooling has eliminated the need to scrap existing systems which have become overloaded. And in new system design, subcooling not only delivers more uniform, efficient operation, but also allows down sizing of some components like compressors and control valves.
