​​McKinley Service and Equipment Inc. is your State of Alaska dealer for ElectraTherm & the Power+ Generator™

ElectraTherm, Inc. is a leader in small-scale waste heat recovery. ElectraTherm’s fuel-free, emission-free Power+ Generator™ can convert sources of low grade waste heat (Internal Combustion Engines, biomass boilers, etc.) into power, and offer an attractive payback period on investment. Incorporated in 2005 and headquartered in Reno, Nevada, ElectraTherm is a privately held company.

ElectraTherm's Power+ Generator™​ converts low temperature water flows (between 190°F/88°C and 240°F/116°C) into fuel-free, emission free power. The Power+ Generator™​ output range is from 30-65kW, based on temperatures and flows.

The machine has low input requirements for its hot water supply relative to other ORC systems. The Power+ Generator™ has the ability to utilize these low temperature water flows allows its implementation in a rapidly expanding number of distributed heat to power applications. The small footprint, skid-mounted design facilitates ease of installation often where current methodologies for heat to power  solutions  are not feasible.

The Power+ Generator™ is  scalable to each heat source, allowing connection of multiple Green Machines  toa single heat source if enough energy is provided. The Power+ Generator employs a robust design and the majority of machine components are readily available. Routine maintenance is easy, and with basic ElectraTherm training, technicians with an HVAC and mechanical background can handle required maintenance.

Additionally, The Power+ Generator™​ has a​​​​​​​ control system is fully automated, allowing remote control, remote monitoring and off site maintenance.

ElectraTherm’s heat-to-power system uses a closed loop Organic Rankine Cycle (ORC).

Steps in the process:

  1. Heat is captured by the evaporator and boils the working fluid into pressurized vapor.
  2. The vapor is forced through the screw expander, spinning and electric generator creating kilowatts.
  3. The vapor is cooled by a cold water source and condensed back into liquid in the condenser.
  4. The working fluid is pumped to higher pressure and returned to the evaporator to repeat the process
