Hydraulic Systems

Hydraulic pumps and hydraulic power units are a component in many kinds of heavy equipment, from trash compactors to cranes. Hydraulic fluid operates best at a fairly high temperature, and when cold-starting a machine, it's common for the fluid to be too cool, which can cause pump damage – even at room temperature. (Once started, though, a hydraulic machine warms the fluid to its normal temperature in the course of operation.)

The usual method for heating hydraulic fluid is to use a screwplug heater, with a size and wattage to fit your application. In some cases, it may also be possible to use a silicone rubber blanket heater on the outside surface of the fluid tank. Both these styles of heaters can be built to operate at low voltage (typically 12 or 24 V).
