M-100 Free Piston Stirling Cooler (FPSC)

M100B Exterior Dimensions [mm]

The M100B Free Piston Stirling Cooler (FPSC) is among the first Stirling coolers to be introduced to the market. The first production run of this unit allowed Global Cooling (GC) to introduce its technology to a number of manufacturers working in industries from food refrigeration to laser cooling. Not only did the first production runs allow GC to sell demonstrators to interested parties, it also gave GC a chance to field test units in a number of different environments. The feedback and reliability information that we received from these first units allowed us to continually improve the product as development progressed

We are also involved with other manufacturers to develop models of different capacities and of lower cost. Some of these are already available while others are projected to be available to the public in one year. For information on the progress of these programs check this web site since it will be kept up to date.

To investigate the possibilities of using Stirling Coolers in your application you can find detailed information throughout this web site. Check the Technical Papers page for papers on the subject.

EcoValve Electronic Expansion Valve (EEV)

Unique capabilities:   

• Control of refrigerant flow down to exceptionally low rates of 15 W or less of refrigeration.  A range of presently available orifice diameters enables flow control to 1200 W refrigeration, and higher flow rates are possible with a larger valve body.
• Maintains stable superheat of 3ºC, even at low flow rates.
• Physically small and easy to install by brazing into the liquid line at the evaporator inlet. The control unit is small, easily installed, and uses only 0.5W average power.
• Works with all common refrigerants, e.g., R134a, R22, R407C, isobutane, etc.  Can be adapted for CO2.
• Very low leakage reduces stop-start loss and minimum controllable flow.
• Ecovalve has been subjected to rigorous accelerated life tests, and showed no deterioration at the end of the equivalent of 15 years of service life.
• Digital control with an inexpensive microprocessor                                              

Ecovalve operates on the pulsed-flow principle.  An electrically actuated reed valve is pulsed open at two second intervals. Flow rate is proportional to the fraction of the pulse interval during which the reed valve is open.  That fraction is controlled by superheat as measured by thermistors. Stabilization of superheat is achieved with an inexpensive, passive, “superheat stabilizer”, which performs the function of an expensive PID control and is, in its simplest form, a section of tubing typically 20 mm Diameter x 200 mm length, in the suction line preceding the thermistor that measures vapor temperature.

"The Coca-Cola Company, based on laboratory and field tests, endorses Global Cooling's expansion valve (sold as the "Ecovalve") as an option that can improve energy efficiency, increase the cooling capacity and lower initial pull-down time across a broad range of ambient operating temperatures of sales and marketing equipment. The installation of the Ecovalve is an effective tool to improve the environmental impact of new and refurbished sales and marketing equipment. A technical fact sheet is available on request or at www.globalcooling.com.

Please note that equipment that has been redesigned to include the Ecovalve would need to be submitted for re-certification to confirm performance and efficiency prior to our system's inclusion of the valve in its purchase plans."
