NRG Energy inquired about heating an outdoor pump to prevent it from freezing we knew it was right up our alley. Many of our industrial heating jackets live outside and can withstand all sorts of weather. The waste water pump (Gould Pumps) doesn’t run except for an hour at a time. Because the pumps are exposed to New York winters, keeping it from freezing was a must, and our pump insulation jacket can keep the water flowing. Custom outdoor pump insulation heating jacket, quick delivery, durable and competitively priced.
