All Hot Patch models feature a triple-layer steel bed. The middle layer of the bed consists of carefully designed flow channels between the inner and outer layers of the bed.
A fluid is circulated through the bed and is heated through a 120V overnight heater and, on most models, an onboard diesel fired heater. The result is a uniform heat across the bed that evenly heats patch mix to optimized temperatures.
Hot Patch Heaters are designed to not overheat cold patch material. Cold patch material that is overheated will begin to break down and lose most of it’s binding properties. Trying to heat cold patch material in a “hot box” will frequently cause the material to be overheated.
For nearly 20 years Hot Patch Heaters have been used by municipalities, street and water departments, county highway departments and state-level DOTs. These same types of customers with medium to large scale patching needs will appreciate the many upgrades incorporated into our redesigned EVO full size models.
Hot Patch also offers the LT Pothole Patcher. The LT (Light Truck) models are designed to fit between the wheel wells of a standard pick-up truck. Using much of the same technology as our full-size models, the LT will greatly improve patching for small townships, universities and property maintenance companies who may have small to medium size patching requirements.
