Multi-Max Pump Control Systems MULTIPLE speed pump control systems providing MAXIMUM energy savings: · SAVEs MONEY $$ · IMPROVEs ICE QUALITY · INCREASEs EQUIPMENT LIFE · BOOSTs SYSTEM EFFICIENCY Multi Speed = Max Savings It is a well known fact that rinks are penalized twice for operating a brine or glycol pump in a typical indirect refrigeration system. For example, a 30 hp brine pump motor will draw about 22 kW whenever it operates. When running constantly, it costs about $15,000 per year just to run the pump. The same 22 kW also adds a 5 ton heat load to the refrigeration system in the form of frictional heat in the pipes. To refrigerate this heat, it adds another $3,500 per year in operating costs for a total of $18,500. While this $18,500 is all a result of operating the brine pump, up to 50% or $9,000 can be saved by using a Multi-Max pump control system. How It Works Only Multi-Max matches the brine flow with the refrigeration system output. Since the sole purpose of the brine pump is to transfer the refrigeration effect to the rink, the operation of the brine pump should directly match the operation of the compressors. The Multi-Max system pumps 100% brine flow with 100% refrigeration output, and 50% brine with 50% refrigeration etc. And, when the compressors are off, the Multi-Max system turns the brine pump off too - and that means MAXIMUM ENERGY SAVING. While there are many drive and pump control systems available, only Multi-Max pumps the right amount of brine at the right time - no more, no less. You can Increase Multi-Max savings even further with other optional features including: · EnergyEye infrared ice surface temperature sensors. · Ice Temperature Scheduling on a 24 hour, 7 days basis · DDC Controls with remote communications & graphical display · PID Control for the very best ice temperature control · Multiple Ice Sensors or control from multiple ice surfaces NB: For related articles on brine flow and refrigeration please visit our EnergyIce Publications library. |
