### N45

###### SANDING

##### N45

**Customer benefits**

##### Multi-step dosing device

##### Precision at the Core: The Dosing Device That Powers Your Sanding System. At the heart of every efficient sanding system lies our advanced dosing device — engineered to deliver consistent, high-performance sand flow from sandbox to distribution pipe.

##### Magnet-Activated Piston Technology: Experience unmatched precision with infinitely adjustable sand batching, ensuring optimal dosing for every application. The secure closure mechanism guarantees safe containment and handling.

##### Versatile & Reliable: Compatible with a wide range of sand types, our dosing system ensures high delivery accuracy and seamless integration into diverse industrial setups.

Sealed for Reliability: Like all Wabtec Nowe dosing systems, the Z30 ensures complete sealing of the sand container post-activation. This prevents moisture ingress, guaranteeing maximum system reliability and long-term performance.

### Z30

###### SANDING

##### Z30

**Customer benefits**

##### Multi-step dosing device

##### Z30 Sanding Dosage System – Precision That Drives Performance. When adhesion recovery depends on sand delivery accuracy, the Z30 electrically driven dosing unit delivers with unmatched precision. Its speed-proportional sand flow ensures optimal performance across all train operations

##### Smart Control, Precise Flow: The Z30 features an electronically controlled cell wheel powered by an electric motor. Sand flow is finely tuned via motor speed, enabling highly accurate and consistent dosing.

##### Sealed for Reliability. Like all Wabtec Nowe dosing systems, the Z30 ensures complete sealing of the sand container post-activation. This prevents moisture ingress, guaranteeing maximum system reliability and long-term performance.

### P15

###### SANDING

##### P15

##### Easy to integrate Dosing Device

##### The P15 is a pneumatically actuated piston dosing unit for precise and stepless dosing of sand and for securely closing the sand container to the environment.

##### It has been specially designed for quick and easy integration into vehicles, especially for retrofit on existing vehicles.
