Product Description

ESUN CRJ-450 Polypatch hot melting patching material melter has two large openings for easy material loading. Advanced digital temperature controls maintain accurate material and oil temperatures and feature an auto flame shut down for safety. The products are thoroughly mixed by a horizontally mounted internal shaft with sweep paddles. To clean the Patcher for material type changeover, load the Patcher with clean aggregate, run the mixer and then empty. The ESUN CRJ-450 Polypatch hot melting patching material melters are designed to efficiently melt Roadbond polypatch products.



Designed for large cracks, manhole, bridge joint, etc. Our asphalt melter provides with functions of heating and mixing Roadbond and aggregate.



1Concentrated temperature control

Dual digital LCD temperature controller: Display and adjust the heat transfer oil and material temperature timely, guarantee the construction quality. 

2Circulated agitating and heating system 

Special designed agitating vane drawing the melted mixture from bottom to top achieves circulated heating and reduces heating time.

3Synchronous heating and agitating

Synchronous heating and agitating once material filled in guarantees the heating efficiency. 90 minutes from material loaded to melted provides sufficient working time. 

4Two mode on agitating and heating

Independent and synchronous working mode. Heating on while agitating off when no need of material discharging; if discharging is needed the agitating start work, discharging material in 5 minutes guarantees the construction efficiency. 

5Auto clockwise & anti-clockwise circulated agitating

Controlled by PLC, avoid stuck under only heating status and speed up heating and melting process.

6Independently cooking aggregate 

The melter can cook or dry aggregate independently.

7Heat transfer oil

Oil jacketed melter with less heat transfer oil compared with other products improves heating speed and reduces cost. 

8Special designed combustor

45°downward flame, in-direct heating the melter, sufficient burning with high heating utilization.

9. Skid mounted design

Popular method of distributing and storing, can be easily and securely transported and used.
