ARVEL brine spreaders are used to store and spread a saline solution – brine – when a road is frozen or to prevent it from freezing. If necessary, after first undertaking a feasibility study our design department will be able to de define the main characteristics of the kind of carrier vehicle required based on the amount of liquid to be carried. By combining the capacity of a number of tanks the quantity involved can be up to 18,000 liters and it may be transferred for storage purposes or to supply other vehicles using a drain outlet provided as standard on the machine.
Thanks to their low center of gravity design, ARVEL brine spreaders are well suited for direct mounting on a subframe or placing in a tipper.
As standard, four lifting rings are provided for handling or for raising or lowering the machine using an overhead crane.
A centrifugal pump installed in the technical compartment is made entirely from AISI 316 stainless steel. It is specially designed for use under extreme conditions.
A motor controlled valve is placed on the pump’s pressure line, for accurately controlling the flow rate. An electronic sensor fitted to the equipment as standard is used to place the pump in safety mode when there is no liquid solution onboard.
The liquid is stored in a set of interconnected modular polyethylene tanks mounted on a chassis. This design choice allows having a structure that remains flexible when directly mounted on the carrier chassis. Further, this division into cells stops the complete contents from sloping around, helped by the tank baffles, to ensure that the carrier vehicle can be driven in complete safety regardless of how full it is.
The top of the storage tanks is provided with a non-slip coating so that the operators can access the manholes in complete safety.
The solution is sprayed through stainless steel rails and nozzles mounted on the rear of the vehicle. They are supplied in line with operator instructions and based on the vehicle’s forward speed so that the solution sprayed on the roadway is always consistent. This is called speed-sensitive control. In addition to this function, it is also possible to use the control box located in the cab to select the desired spray width as well as the area to spray (right, left, center).
Drive system using the carrier vehicle’s hydraulics
The brine spreader can be run off the carrier vehicle’s specialized winter clearance equipment circuit as the equipment is compliant with European Standard EN 15431.
The necessary flow rate is 60 liters per minute with a maximum pressure of 220 bar
Auxiliary diesel engine drive system
The brine spreader may be equipped with a two cylinder air cooled 16 kW (22 hp) diesel engine. It has an electric starter controlled from the cab. It is located in a technical compartment to protect it from corrosion.
The engine comprises:
The Ecosat10 control box is equipped with a microprocessor with a wide range of possibilities for programming and viewing the various spreading parameters (spreading width, asymmetry, dosage)
The control box comprises the following elements:
It communicates with the external power unit via a CAN-BUS connection (a Bluetooth link is optional).
This control box controls the spreading of six different materials (calcium, sodium, potassium, etc.) using nine spreading programs per material. You can save different types of settings for spreading, asymmetry, spray width, type of material, etc.
The electric power circuit is protected in a sealed box and the electrical outputs are protected by electronic technology for detecting faults and protecting components.
Note: The brine spreader is equipped with a system for operating in manual mode.
Increasing the spreading width
Three nozzles on the right and three nozzles on the left are added to the original system to achieve a maximum spreading spray width of 17.5 meters. This system too is linked to vehicle speed.
The stirring system uses a pump to stop a layer of salt brine being deposited at the bottom of the tanks.
High Pressure System
All Arvel brine spreaders are suitable for use with a wide range of storage support systems. They are designed to reduce as far as possible the time required to fit and remove the systems and they are suited to all requirements and all vehicles.
For vehicles equipped with a tipper body or flatbed:
Wheel operated support stands
A support system using four telescopic manual wheel operated stands. The front stands are designed to pass over the side panels.
Automatic support stands
An automatic support system for tipper bodies with front supporting rollers, front stands that retract into the brine spreader’s chassis and retractable rear supports.
For vehicles equipped with an arm (Ampliroll type):
Removal cradle for Ampliroll arms
The brine spreader is mounted on a cradle equipped with a front hook and two offset rear rollers. To protect the carrier vehicle’s mechanical systems, a polyethylene base if fitted between the two.
