The challenge
Efficient and cost-effective cooling of submersible motors is a constant source of discussion by well and mine operators. Derating is a less-than-ideal solution. In addition to high capital and energy costs, the overlarge, downgraded motors usually require a larger well diameter. Oil cooling needs careful consideration as well – any failure can cause ecological damage.

MC-T – The solution
MC-T, an intelligent and compact cooling system, is the best solution here. A pump impeller brings movement into the cooling circuit and thus provides flow in the right direction. Our own-development cooling channels ensure heat absorption at all thermal sources and heat evacuation, as well as providing optimal heat conduction through the outside of the motor to the flow medium. The additional use of heat exchanger modules allows precise dimensioning of the cooling capacity.

Technical details and economic benefits:
  • Media temperature up to 75° C
  • High efficiency across the entire performance range
  • Uses drinking water as the coolant
  • Low investment required
  • Reduced energy costs
  • Maximum reliability
  • Long service life
