How to Prevent Frozen Trash Compactors

As the cold weather settles around us again this year, you may experience the occasional compactor freeze-up. In an effort to minimize the potential effects of this situation, Waste Harmonics would like to remind you of our guidelines and how you can reduce the impact of a frozen compactor.


There are a few basic tips we can provide to help minimize the risk and expense of a frozen compactor:

  • Liquids – Rather obvious, but especially during the winter months, reduce or eliminate liquids from your waste stream. By not throwing water, milk, juice, ice, and other types of liquids in the compactor you can greatly reduce the potential for a compactor freeze-up.
  • Salt/Urea – Dependent on the overall use of your compactor, occasionally during
    your daily operation of the machine, throw a small amount of rock salt or urea into
    the compactor. This will help prevent any liquids in the machine from freezing solid, preventing the machine from operating, subsequently causing damage to the equipment.
  • Operation – If you do not use your compactor consistently during evening hours, a “warm-up” cycle is recommended for the compactor prior to regular use. Cycle the compactor ram in short cycles for a brief period to ensure that the compactor ram can move adequately in and out. Doing this not only can prevent major damage, but can also warm the machine cylinders, pumps, valves and oil, which has the effect of easing the equipment into use.


If your compactor stops working during the winter months, please call Waste Harmonics so we can dispatch a repair person and advise you of how we can resolve this issue. If the compactor has stopped working because of frozen materials, you will be charged for the service calls necessary to bring the compactor back into working order. If it is determined that the compactor has broken down for another reason, Waste Harmonics will make the repairs at no cost to you.
